I started watching your channel with the Oroville Dam . Because the regular news was not covering it . I have since learn to enjoy your perspective partly because you have let your viewers know you as a person . Thank You for your efforts ! Steven Smith Lansing NY Finger Lakes Region NYS
G'day Jaun Congrats on 100k subscribers. It shows people appreciate your videos for the honest, no nonsense info you cover. It also shows we love your videos on family, the mighty Luscombe, flying, music, airshows, motorbike rides etc. Keep up the fantastic videos. And thankyou for sharing your knowledge with us. Here's to your next 100k subscribers 🍺
Again, congratulations! Great content on the GE9x and a fantastic bonus nugget! I’m a metallurgist with a PhD and background in aerospace composites and coatings who moved to California a few years ago to continue my career in materials development - now doing R&D in metals including Ti and even gold alloys... I first discovered your channel with your fire tanker videos. Your channel has become my favorite with every video being well worth watching... I’m always very impressed with your content.
Congratulations on the 100K subs. I ran in some Kewit guys and asked if any of their crew had worked on the Oroville Dam project. One kid had and I thanked him and asked if he knew of your channel. He didn't know but I wrote it down for him and he most likely will be a new sub. Great report Juan.
100K...woohoo!!! That is amazing Juan! You have grown this channel thanks to YOUR presentations of all that is aviation. Lets get to 200K and change aviation for the better! Be safe and be kind to one another.
I originally found your Channel with the Oroville Dam updates. I stayed with your channel because you don't give us any bullshit just the facts. And I've come to enjoy your content a lot. Congrats on 100k keep up the good work Juan. Tip of the hat from south of you in Ione.
Just a slight technical correction if I may: Engine Pressure Ratio, EPR, is measured by exhaust total pressure, P5, divided by fan inlet total pressure, P2. Some commercial turbofan engines use EPR to gage their thrust output with respect to throttle lever angle. High Pressure Compressor, HPC, pressure ratio is compressor exit static pressure divided by compressor inlet static pressure. But for these huge turbo fan engines, I believe total "engine" air compression ratio might be HPC exit static pressure divided by ambient air static pressure. This would take into account the pressure increase imparted to the airstream entering the engine from the fan, Low Pressure Compressor, LPC, and HPC. Past the HPC is the combustor which can be considered a constant pressure process for simplicity. Then comes the turbine section, the first set of turbines is for generating HPC shaft power and the last set of turbines is for generating fan and LPC shaft power. Any energy left in the airstream past the turbines is exhausted out through the exhaust nozzle and contributes a "little" bit to the overall thrust output of the engine. Most of the thrust is generated by the air exiting the engine from the fan. But as these turbofan engines get bigger and bigger, the more I think they are becoming turbo "prop" engines where all the energy in the gas stream past the combustor is being used to generate shaft power to spin the fan with very little energy left to impart forward thrust via the equation, thrust = (air mass flow)*(V'exhaust - V'inlet).
@@gordonrichardson2972 That's OK by me though. I have great respect for pilots. Piloting an airplane is something I would find nearly impossible for me given my level of dyslexia. Too many switches in a flightdeck!
Congrats. It's comforting to know that there is now 100,000 followers that will realize the truth about your subjects. Gee that feels so good. On your last update I think there trying to get to much out of these engines.
Congratulations on attaining 100k subscribers, there are now 100k better informed people thanks to your no-nonsense thorough presentations, a Broncolirio notification is always a treat. The 'bonus' feature in this presentation was very informative too. Keep it up, and continued good health, see you here!
Congrats on 100k! Well deserved. Started following after doing a search for the Orville dam. Probably 8k at that point. Really enjoyed the dam info and now the 737 and 777 updates. Lots of family history with the 777. Keep up the quality content!
It's interesting how technology has moved things ahead in every walk of life. The German Axial Flow engine was a superior design over the Centrifugal Flow engines we used, but they wouldn't hold up as well. Same thing with P-38's using copper tubing that had to be pulled out of the plane and annealed every so many hours. Then along comes aluminum tubing that was halfway trouble free from fatigue and didn't have to be annealed. I have to admit that the thrust the GE9X puts out really surprised me. Back when I was in the Navy(1966/1970) the big engine on the block was a J-79 that produced about 16,000 pounds of thrust in full after burner! Something producing over a hundred thousand pounds of thrust is unbelievable for an old timer like me!..........Another very informative video, Juan. Keep these puppies comin'.(:>)
As usual for Juan. A comprehensive layman's update on some very technical material. I thank you for the work you put forth to bring exceptional content to your channel. And a big congrats on the subscriber milestone. Can we do a million? I think so.
Superb video Juan - it has everything...aviation economics, physics, materials science...and the rest, all easily understandable....and connecting it all back to the gold rush history at the end there was just genius!! Mega congrats on 100k from me in the UK - hoping your freedom to fly will be restored ASAP but in the meantime do continue with more awesome blancolirio content. Thank you!
Outstanding report that any layman can understand more now of how turbines work. The little tour of you town at the end peaks my interest to visit. Some great history there. I also noticed a winery in the background!! Thanks Juan. Love your reports.
Honestly people - the B777 is without any question the finest commercial jet aircraft I've ever had the privilege to operate. From the 200A to the 300ER, these aircraft are the Creme de la Creme - the Best of the Best out there today. The 777 is an absolute DREAM to fly: honest, powerful, efficient, and at the same time a BEAST. Its made me look good a great many times even in challenging situations. With 12000 hours in the Triple, I know it well, now but can't wait for these GE9X's to come out. We pilots (and I know you'll agree Juan) have a saying: "In Thrust we Trust" Boeings troubles aside, this is one fabulous piece of aerial engineering artistry: The B777! edit: Oh yeah - 100K subs. You worked for it and you're worth it. May there be much success to come! Cheers Juan...
As an engineer, I used to give tours at the Bonneville Lock & Dam and the Folsom Historic Powerhouse. From everything have read, while experimenting with the single bucket wheel, al la the Kinght Wheel, Lester Pelton noticed that when directing the water stream at the side of the bucket the wheel sped up. That's because when hitting the bucket the direction of the water is reversed imparting more energy to the wheel. The split wheel was a further development.
Thank you for the video Blancolirio, it was informative and educational, my kind of video. I remember when I lived in Albuquerque, NM years ago, going over to the GE plant there, where my Uncle Will worked. He invited me to their open house and to say the least I was seriously impressed. At the time they had just started building the GE 90 intakes, the nacelles and intake stator vanes, which I believe are fixed in place, and all the other parts that make up the outside of the engine. It was amazing to see all of the machinery they use to build these engines and the science behind building them. They have one section where there's a container filled with water which they place stator vanes in to do ultrasonic test to make sure that there isn't any micro fractures in the material, it's all a very exact science. What impressed me the most was walking up to a GE 90 intake they had standing up and looking up at this massive intake that you can fit a 737 fuselage in, folks just can't appreciate the size of these engines until they see them in person. One of the men there that was crating an intake to send out to GE's final assembly plant, where the inner part of the engine is made,which is in some other state, told us back then that the engine was said to put out over 130,000 Lbs. of thrust or maybe what he meant was that GE's final objective was to reach that goal with the design. Or maybe the lower thrust levels they've been running them at, are a derated setting, I don't know, but they are absolutely amazing engines and they make one of the coolest sounds in jet engine history. Thank you for the quality videos and God bless you.
Mind-boggling present-day aviation tech, followed by significantly more understandable and extremely interesting gold mining tech from the CA gold rush. Great video, Juan, and congrats on reaching 100K subscribers.
Thanks for the Nevada City featurette....It adds that extra bit of history of Gold that most of us never knew...and how the turbine concept migrated from history.
Congratulations Juan. You deserve the success you've achieved. You're work, from reporting on the Oroville dam to the 737 Max, has all been a high quality of presentation of facts and entertainment rolled into one. One word sums it up, fantastic!
The thermal efficiency of an engine is directly related to the maximum operating temperature of the heated gas running through the engine and doing the work. Specifically, the efficiency is determined by how hot the gas is when it starts doing the work, and how much it has cooled doing the work. The limiting factor is how hot this gas can be. The tolerance of the materials and the extent the material can be cooled limits the max temperature achievable. This is difficult to do in a turbine engine because the turbine blades must be constantly exposed to the hot gas without any easy way to cool them. Ceramic materials and blown cooling air through the inside of the blade itself are attempts to increase the turbine inlet temperature limit.
Cray Research used Flourinert (tm) to do similar cooling of the mount bars for internal cooling of the X MP and Y MP systems. The whole supercomputer was in-cased in Flourinert (tm) in the Cray 2 and proposed for the Cray 3. This material was so inert , you could breathe it with added oxygen, much like the divers in Abyss. If you let the mixture get too warm. it breaks down into very toxic chemicals. 3M could figure out a high temperature version for jet engine cooling. We used it to heat our buildings in winter via a heat exchanger.
As a retired A&P, I love the technical reporting. I also am a pilot want to be so I love the pilots aspect as well. Thank-You Juan, and congratulations on the 100,000 subscribers. See you at a Million!
Thanks Juan!! Just love the way you report the facts. Especially the Pelton Wheel!! OMG, LOVE the gold demo....... Such cool stuff. Weav And Congrats on the 100,000 subs!!! You have got to be feeling proud! You earned it! The public responded!
Yea brother! And also, I work on the 777X wing. Man, your talk of the gold, this ole Texas boy has spent many a day panning the Yuba River. I miss those days. Thanks for all the great content brother!
You outdid yourself on this report, Juan. Superb and congratulations on reaching the 100K milestone ( No doubt Google will reward you by sticking advertising on the end and 15 seconds before the end!! )* * I know, I know... I am sceptical.
Well deserved 100 thousand subscribers. The side trip to the gold processing was interesting. We have a lot of the same history in Upper Peninsula of Michigan, in this case copper. A lot of abandoned infrastructure. When the money ran out so did everybody. Thanks for keeping us up to date on the straight dope about aviation , it's good to hear from somebody who knows what he's talking about.
Congratulations on the subscribers. You made a good point in engine testing through the FAA. No rush needed, Boeing and the FAA have to regain some trust Internationally. Keep the videos coming!
Great explanation of the jet engines and what makes them better. Although a little in the weeds for this old farm boy. Always enjoy the seeing the old gold machinery and the technology of a bygone era. Congratulations on making the 1 plus K viewers. You have earned it with straight forward analysis, style and interesting presentations. Good health my friend and hope you are back in the right seat soon.
Well explained with great technical knowledge and detail, but simply stated and clear for folks of a wide range of backgrounds. This is why you have 100k subscribers. Congrats
Congrats on 100K! Always loved your content on aviation related update, now history of gold in California. Now I'll have to check out the Pelton wheel. 777 is a fabulous aircraft, we routinely put 15 to 20 tons of cargo on our 300ER with fairly full PAX load between SFO/HKG. Hope GE get the blade issue sorted out soon.
Congrats! Like many others, I've been watching since Oroville dam incident. I was so impressed by your knowledge, I guessed you were an engineer, but pleasantly surprised by your background. Thank you!
Thanks very much for the explanation of the Stator Vane issue. I'm sure GE is going to monitor these (borescope) religiously in the early model engines. Russ Bell
Woah! I wasn't watching your sub count. Seems like only yesterday you were Juan Browne with the small channel that started posting real information about Oroville. I think you had a few thousand subs back then. I'm really happy for you, Juan. Your content is always interesting. Say g'day to your family for me.
VERY well deserved achieving 100,000 subs’ congratulations to you Sir! PS. I didn’t understand a word about the jet engine dynamics & science which you painstakingly articulated so brilliantly - BUT it was so utterly fascinating, I watched it TWICE! 🤣👏🏼👏🏼
That a non rotating part in a relatively benign area of the engine is the cause of the delay problems is kinda surprising. I would have guessed something in the hot section to be the source. And as a long time gold and silver afficianado I really liked the last part of this vid! Congrats on 100k!
terry boyer he incorrectly stated that the problem was with the “fixed stator blades”. The problem was actually with the “variable stator vanes”. While they are not rotating as in compressor rotation they are a moving part in their own independent way and do encounter stress.
Juan, the FAA test requirement for engine cycles is 3000 cycles. That is/was start to idle, run to takeoff thrust, back to idle, reverse thrust, idle and shutdown. Rinse and repeat. I recall that it takes about 20-25 minutes per cycle. Probably around 500 cycles, they'll pull the bore-a-scope plugs and inspect. Then every 500 cycles, and a full tear down at 3000 cycles. Peebles Ohio Engine Test is going to be quite busy, so anyone living in the area has probably heard an increase of test engines. One thing about test engines, is that test engines are tested at the maximum out of balance condition, as well as tested @ 10% under rating of thrust as well as 10% over rate. Boeing and GE can run a condensed flight test program, by doubling up on the number of tests run per day, provided they have test personnel and aircraft available.
I sincerely hope you stay in Nevada City (or the area for about a week. My suggestions, if it's o.k. for me to be so bold: visit the Empire Mine State Park, in Grass Valley. Also Malakoff Diggins State Park. Then North San Juan and Downieville. Up from Downieville is Sierra City and the Sierra Buttes. The Buttes are best seen from the interior. I like Sardine Lake Lodge and the lookout tower. After that, continue on Hwy 49, then turn right to Sierraville. There's a hot spring there. Juan showed it on a video once. Continue South to Truckee. You'll be a short trip from Lake Tahoe, if you haven't already seen it. Or, turn right onto I-80 at Truckee, wait, no, better to drive along Donner Lake and drive up Donner Pass Hwy., stopping for photo's along the way. You can intersect with I-80 after Soda Springs. From there, you would exit I-80 at Hwy. 20, which will take you back to Nevada City. If you want a gold nugget, you should be able to buy one somewhere between North San Juan and Downieville. Maybe find a miner at the river, or maybe there will be a rock shop along the way.
When you said "California Gold", it made me think back to Huell Howser and his public television series, "California's Gold". I spent many happy hours watching that program.
Really nice report. And that "bonus track" made me want to visit that gold mining town the next time I'm in US and have a reason to visit the west coast. And congratulations on the 100k subscribers too. It isn't too hard to get subscribers when you have good USP and manages to present the information in a way that is pleasant to view.
Juan..your next 400k subscribers will go very fast! I am still holding my breath for you to take us all on your NEW SIMULATOR ride on the 737MAX. We know you will be called by Boeing soon enough. Of course Boeing engineers watch your channel. Anyone with brains and love of aircraft watch your show! Great forum, keep up fine work! Question: are not the Rolls Royce Trent 1000 series and other high performance engines ALSO experiencing stator vane material breakdown? The SouthWest 737-8 had an engine failure, which sucked a female passenger out of airplane at altitude. I believe this was 3-4 years ago. The female Southwest PILOT did a fantastic job of damage control, bringing aircraft to a safe landing. The base of the stator vanes were pretty much immediately inspected by a nifty test. Thanks for your reports!
Nevada City sounds like fun. Maybe I should add it to my bucket list? Many congratulations on the 100k, I think it was around the 30k mark when I subscribed. You've done well Juan.
Oh wow! We are heading up there today for the Draft Horse Classic. But we will definitely be making another trip up soon to visit Nevada City and Grass Valley and their museums very soon! Love your channel.

I’ve been watching your RUclips channel since the Oroville dam incident. Congratulations on the 100k subscribers. Great videos and greater reporting.
Also, I might be incorrect but is it a turban engine or turbine? It might be in the pronouncement.
Yea brother! And also, I work on the 777X wing. Man, your talk of the gold, this ole Texas boy has spent many a day panning the Yuba River. I miss those days. Thanks for all the great content brother!
Thanks Lonnie! And keep up the good work. That wing is beautiful.
One of a hundred thousand here. Can’t say how much I appreciate your videos. Congrats, keep it up I really like your no bs facts. Thank you.
Double congrats on both 100K and being able to explain stator vanes 👍🏼👍🏼

Today is a day to celebrate ! 🎉🎉
Congrats Sophie!
@@blancolirio Thank you so much !
Congratulations on the 100k!!!
Well explained with great technical knowledge and detail, but simply stated and clear for folks of a wide range of backgrounds. This is why you have 100k subscribers. Congrats
I am thrilled to hear that 100,000...A HUGE CONGRATULATIONS..!!
Congrats on 100K! Always loved your content on aviation related update, now history of gold in California. Now I'll have to check out the Pelton wheel.
777 is a fabulous aircraft, we routinely put 15 to 20 tons of cargo on our 300ER with fairly full PAX load between SFO/HKG. Hope GE get the blade issue sorted out soon.
Congrats on the 100K. Those numbers are really taking off ✈️
Congrats! Like many others, I've been watching since Oroville dam incident.
I was so impressed by your knowledge, I guessed you were an engineer,
but pleasantly surprised by your background. Thank you!
100K subs, Awesome-sauce!!!! You're the best, Juan!! Thanks for the history tidbits too in Nevada City; we'll check it out one day here soon👍😊
Congratulations on 100,000 subscribers! Your content is excellent! Thank you
Thanks very much for the explanation of the Stator Vane issue. I'm sure GE is going to monitor these (borescope) religiously in the early model engines.

Congrats on reaching 100K Juan! Great and interesting content!
Woah! I wasn't watching your sub count. Seems like only yesterday you were Juan Browne with the small channel that started posting real information about Oroville. I think you had a few thousand subs back then. I'm really happy for you, Juan. Your content is always interesting. Say g'day to your family for me.
Congrats Juan, I really enjoy your reporting. You make it easy for us to understand and give us fact based reporting.
Thank You.
VERY well deserved achieving 100,000 subs’ congratulations to you Sir! PS. I didn’t understand a word about the jet engine dynamics & science which you painstakingly articulated so brilliantly - BUT it was so utterly fascinating, I watched it TWICE! 🤣👏🏼👏🏼
Congratulations on 100K! Love the channel and look forward to many more updates
Congratulations on 100k subs! You deserve it, Juan.
You should get a gold pin for 100K Jaun, congrats buddy. I'll see you here.
Juan,
Congratulations on 100K subscribers!
Great update and explanation on the 777X/GE9X status - thank you!
God bless

That a non rotating part in a relatively benign area of the engine is the cause of the delay problems is kinda surprising. I would have guessed something in the hot section to be the source. And as a long time gold and silver afficianado I really liked the last part of this vid! Congrats on 100k!
terry boyer he incorrectly stated that the problem was with the “fixed stator blades”. The problem was actually with the “variable stator vanes”. While they are not rotating as in compressor rotation they are a moving part in their own independent way and do encounter stress.
@@aaronbennington9942 Thank you for clarifying that. Variable stators are certainly more complicated.
Juan, a Hugh shout out to you on the 100K SUBS, and thanks on the engine update , as always. Cheers from NJ
Congratulations on achieving 100k subs, well deserved, your videos are always informative! Thanks again!
It was nice see you today at KGOO. Thank your for the videos!!
Thank you Juan for all you do, as a Gold prospector myself I especially enjoyed the aside at the end ! Lots of rich history around there.
Congratulations on 100k subs! Well deserved, sir.
Juan, the FAA test requirement for engine cycles is 3000 cycles. That is/was start to idle, run to takeoff thrust, back to idle, reverse thrust, idle and shutdown. Rinse and repeat. I recall that it takes about 20-25 minutes per cycle. Probably around 500 cycles, they'll pull the bore-a-scope plugs and inspect. Then every 500 cycles, and a full tear down at 3000 cycles.
Peebles Ohio Engine Test is going to be quite busy, so anyone living in the area has probably heard an increase of test engines.
One thing about test engines, is that test engines are tested at the maximum out of balance condition, as well as tested @ 10% under rating of thrust as well as 10% over rate.
Boeing and GE can run a condensed flight test program, by doubling up on the number of tests run per day, provided they have test personnel and aircraft available.
That makes more sense. Thanks Gunga!
First off, congrats on 100K! That 9X engine is a beast - I can't wait to see the 777X in flight.
Congratulations with the 100,000 subscribers Jaun you have done a wonderful job on your page , always so very informative .
🎉🎉🎉🎉congratulations Juan on hitting 100,000!!!!!
love the topic...was part of growing up for me since development of the fan blades was my father's occupation back in the 60's
Congrats on 100K - not surprised, think that's just the beginning!
Congratulations on your 100k subs, that silver play button is well deserved!
100,000+ subscribers congrats sir good content always draws the crowd's
and quality keeps them coming back. 🎉🎊
Thank you Jaun for the engine update awesome explanation!
Congratulations on 100k subscribers see you here my friend
Ken
Juan well done on 100k fella you deserve it fantastic channel, and as always respect and best wishes from across the pond keep up the good work....
Congrats on 100k!! Very well deserved Sir! ( :
Hip hip hooray!! 100K!! Looks like a good video. Will watch it later. Be well. 👍👍✌
Congrats on the well deserved 100K. Silver play button time. :)
Thanks so much for sharing your knowledge and the bonus clip at the end ... Nevada City here I come ...
I sincerely hope you stay in Nevada City (or the area for about a week. My suggestions, if it's o.k. for me to be so bold: visit the Empire Mine State Park, in Grass Valley.
Also Malakoff Diggins State Park.
Then North San Juan and Downieville. Up from Downieville is Sierra City and the Sierra Buttes. The Buttes are best seen from the interior. I like Sardine Lake Lodge and the lookout tower.
After that, continue on Hwy 49, then turn right to Sierraville. There's a hot spring there. Juan showed it on a video once. Continue South to Truckee. You'll be a short trip from Lake Tahoe, if you haven't already seen it. Or, turn right onto I-80 at Truckee, wait, no, better to drive along Donner Lake and drive up Donner Pass Hwy., stopping for photo's along the way. You can intersect with I-80 after Soda Springs.
From there, you would exit I-80 at Hwy. 20, which will take you back to Nevada City.
If you want a gold nugget, you should be able to buy one somewhere between North San Juan and Downieville. Maybe find a miner at the river, or maybe there will be a rock shop along the way.
When you said "California Gold", it made me think back to Huell Howser and his public television series, "California's Gold". I spent many happy hours watching that program.
Once again you provide (and break down) the technical issues to a level we can grasp. Thanks.
Really nice report. And that "bonus track" made me want to visit that gold mining town the next time I'm in US and have a reason to visit the west coast.
And congratulations on the 100k subscribers too. It isn't too hard to get subscribers when you have good USP and manages to present the information in a way that is pleasant to view.
Juan..your next 400k subscribers will go very fast! I am still holding my breath for you to take us all on your NEW SIMULATOR ride on the 737MAX. We know you will be called by Boeing soon enough. Of course Boeing engineers watch your channel. Anyone with brains and love of aircraft watch your show! Great forum, keep up fine work!
Question: are not the Rolls Royce Trent 1000 series and other high performance engines ALSO experiencing stator vane material breakdown?
The SouthWest 737-8 had an engine failure, which sucked a female passenger out of airplane at altitude. I believe this was 3-4 years ago. The female Southwest PILOT did a fantastic job of damage control, bringing aircraft to a safe landing. The base of the stator vanes were pretty much immediately inspected by a nifty test. Thanks for your reports!
Congrats Juan on a Hundred!
Congratulations Captain! I hope you get 100k extra subscribers in very short term! You're a fine and decent gentleman: you deserved it!
Nevada City sounds like fun. Maybe I should add it to my bucket list? Many congratulations on the 100k, I think it was around the 30k mark when I subscribed. You've done well Juan.
Again another fine explanation of a complicated issue for the layman to fully understand the issues relating to Boeing and GE, thank you.
Congratulations on 100k subscribers , Juan !
Congratulations on a well deserved 100K!
this channel’s got heart! lotta heart! will always stay tuned.
Great you've hit 100k viewers. Enjoyed this report and look forward to updates.
Am no pilot but I always enjoy the information that you share. I see you hit 100k subscribers. WOW!
Congrats on 100K subs, it's only going to get bigger.
Congrats on 100K. Love the history lesson.
Oh wow! We are heading up there today for the Draft Horse Classic. But we will definitely be making another trip up soon to visit Nevada City and Grass Valley and their museums very soon!
Love your channel.
Congrats on 100k.
Also, thanks for the history lesson. I like stuff like that.
