Kermit, I watched all of this series. I never cease to be amazed at your abilities as a natural pilot of "all things flying". After 22 years I will soon have a very unique aircraft of my own design and guess what? It's a gyro! Thanks for sharing your experience. I hope to see you again one fine day.
Since no power is being consumed by the rotor system, it is in a constant state of autorotation. It free wheels do the relative wind. If the engine quits the aircraft is already in autorotation. In a helicopter the main and tail rotors are powered up until engine failure. The pilot must actively enter autorotation by lowering the collective and adjusting the tail rotor pedals.
I have 26 years experience in fixed wing flying and took a demo flight in a Magni M16 gyroplane last week. It was incredible and I'd like to continue with lessons but I'm concerned about learning how to land it. It would be great if you could comment on your learning experience and any challenges you might have encountered in transitioning from fixed wing aircraft to the gyroplane. Thanks in advance.
Fascinating stuff. I've read about autogyros for years, seen them in museums, etc., but wasn't familiar with the theory behind the rotors. Thanks for the familiarization, and I'm looking forward to seeing your flights!
Great stuff Kermit! I always thought the rotor on an autogyro was generating lift all along its length, in some proportion as long as its turning (being an airfoil) - now I know! Fascinating!
LOL i pity this poor guy. Trying to educate Kermit on any kind of flying must be a daunting task. Anyway Kermit, another awesome snapshot into the world of flying. Cheers mate!
As birds fly their wings change shape in a similar fashion.. this has springy construction that acts like their muscles. You have different forces as he explained.. it's the natural flexibility of the material.. I am developing a bio plastic that is flexible, but much lighter than fiberglass and even carbon fiber.. non proprietary technology.. I worked for a subsidiary of Boeing doing factory floor automation software and database development.. manufacturering high tech fibers for aerospace.. and Raytheon building infrastructure, like oil refineries in Saudi.. we are looking at this technology and I am also developing an atmospheric flyer using the coander effect
Question: has anyone tried uneven number of rotor blades... like 3 or 5... there's a lot less heterodyne in the airframe with the uneven, but balanced forces.. Great information.. muchas gracias señor
Kermie, I swear I could sit with you, share a fine rum and pick your brain for hours. You are unbelievably full of aviation information that is so intriguing to me. Maybe, if I'm lucky, somehow that will happen some day. Love the videos, keep them coming. Ps, sir you are inspirational.
Seems like a pretty complex way to describe lift vectoring. The rotor disc is being tilted left and right which, yeah it makes the trailing blade decrease in pitch while the forward blade increases in pitch but overall, you're just tilting the rotor disc which throws more lift to one side.
Good stuff. I am also interested in gyro's. I am not a pilot yet, but took a ride in Zephyrhills that past weekend. You should offer rides and teaching at your Orlampa site. I've driven by your Fantasy Flight plane on I4 a million times. I am in Orlando and to experience a gyro you must go to Zephyrhills or Sebastain. Your location would be great. Gyro's are now picking up in the states. I see the date of this video is 2017. It appears that much has advanced since then. I watched your channel intro video. Impressive guy you are. I hope to meet you one day. I like your message.
Ground resonance is not a flutter issue it is when one or more blades becomes out of phase with the other and it causes adiyssymetry of rotational mass across the plane of rotation while the rotor disc is in motion. this sets forth an extreme out of balance condition and transmits this negative energy throughout the entirety of the airframe
Agreed. While we know that autogyros do work, it takes real courage to attempt an explanation of how on a high-profile channel like Kermit’s. Serious kudos to Kermit and Dayton!
ETA: Sincere apologies to whoever's reading... I wrote the previous comment with an "understanding" of autogyro aerodynamics that I now know is wildly wrong. I fell into the trap of thinking of the autorotating blades as making a pancake-thin parachute, but with that force of moving air that would go into billowing out a flexible membrane falling in a column of air redirected instead into the rotation of the blades arou ar aro aro I can't see. I've gone blind. I have flipped light switches i my house and I see noghing. The more I think about autogyros the darker it gets. This is bad send hekp
Thanks everyone for all your concern and all the help finding me these last few days! It's sure good to be back on dry land and GREAT to see again! Autogyros sure are complicated! It turned out that I'd reconciled the difference between the retreating blade being a flat-plate airfoil vs. an asymmetric Bernoulli airfoil at the same time as I contemplated hinged blades and that's when I lost my sight. I crawled for days and days, but luckily I toppled from a cliff and fell into the sea where the shock of the cold water stopped me trying to understand autogyros! As I floated there helpless and gawping sightlessly into the sun I slowly came to understand how autogyros just "spin all the drag up." Gradually and by degrees shape and color came back to me and I swam to shore. While we know that autogyros do work, it takes real courage to attempt an explanation of how on a high-profile channel like Kermit’s. Serious kudos to Kermit and Dayton!
Not sure of that answer, but you can go to Dayton Dabbs (my instructor) website and see if you can find the info there. www.lightsportgyroplanes.com/index.php?feature=5&ID=DD01
I am sorry, but a gyro rotor has its blades pitched up between 1-2.5 degrees, UP not down. Your name says it all, you would come a buster, correction you wouldn’t even get airborne, as your rotors wouldn’t even spin up. Man don’t comment unless you know what you are talking about.
I considered gyros last year, but think I will stick to my microlight, for now at least. Thanks for your videos. Please check out my trike flying channel.
We went for the vintage spelling alla Pitcairn-Cierva Autogiro Company and Autogiro Company of America. In the end, all it comes down to is ... "You say potatoe and I say potato."
AHA! 'Tis the Juan de la Cierva (Spanish) spelling. Well, I guess if it was good enough for H.F. Pitcairn, it's good enough, period. I may just use the i spelling for antiques and reproductions of his models, however. I normally just call them gyrocopters anyway, as that name even predates autogiro by a good ten years. :)
He isn't assuming, he's asking informed questions and interacting with his instructor, which is the best way for a smart, educated person to learn. Do you not realize the immense level of his aviation experience and knowledge? He doesn't need a three hour lecture geared towards the dumbest common denominator of student; just getting to the relevant part.
"Its early in the morning and we want to get flying before the Texas heat" 2 hours after figuring out how the rotor works and doodling on a dry erase board...let's go fly! "Its too hot out"...
This would be a better video if you let the teacher teach. I'm a teacher, and I know it's hard for someone who teaches to shut up and be the student, but isn't this video about you taking lessons and being the student?
@@zacklewis342 Is there an atypical uninformed student? If he's already informed, why is he taking lessons? Why involve the instructor in the video at all? I think my point was clear. It would be a better video if he let the teacher teach (not that I am a great teacher or that Kermit is a poor student). It would give a better picture of what autogiro lessons are like if he let us in on the actual lessons.

I fly these gyro’s and i have to say i loved the refresher on the Theory. cant wait for you to post the follow up to this first part of the Gyros

Can't wait for parts 2 and 3.
Thanks, Kermit!

Great Spanish invention by Juan De la Cierva. Articulated rotor head was a great step forward.
Great stuff Kermit! I always thought the rotor on an autogyro was generating lift all along its length, in some proportion as long as its turning (being an airfoil) - now I know! Fascinating!
Hii
Thanks for posting this video!!!
Great questions!
2:45 I think its called conservation of angular momentum.
A whole BUNCH of stuff I did not know. Thank you.
LOL i pity this poor guy. Trying to educate Kermit on any kind of flying must be a daunting task.
Anyway Kermit, another awesome snapshot into the world of flying. Cheers mate!
I think that twist on the rotor is simply because it is flexible, along with the topology of the curve of the airfoil

Great information.. muchas gracias señor
120° is a very good way to get even forces around a circular vector.. this is very good information for me to work with... much appreciated 🙏
Peace ✌☮
Very interesting thanks for sharing.

Every bolt is important!
All the helicopter I have flown do have twist to the blades. I will bet it is the same for the AG.
opposite direction twist for the gyroplane
Nice! Can't wait for part two. Never flown an autogyro. Looks like something that needs to go on the list.
Good stuff. I am also interested in gyro's. I am not a pilot yet, but took a ride in Zephyrhills that past weekend. You should offer rides and teaching at your Orlampa site.

Who is training who?

In addition to this two-bladed main rotor systems are not subject to the effects of ground resonance as he has unknowingly misled you
Nice, will we get to see the Cierva C.30 being flown at some point? or is it a non airworthy airframe?
I see the same airfoil shapes in tailless gliders. or flying wings.
Thanks
I'm comforted to see that you guys don't understand how they work either.

The rotor blades don't flap standing still, they have to be rotating.
Fascinating, looking forward to the rest in this series but, man, doesn't that rotor head and mast look flimsy :-0
It's awesome
Is there an average hours time to learn and get a License ?
Not sure of that answer, but you can go to Dayton Dabbs (my instructor) website and see if you can find the info there. www.lightsportgyroplanes.com/index.php?feature=5&ID=DD01
lets fly this baby!
Ah forget gyroscopic precession the teeter hinge deals with that.
Hi Kermit,
We all want you to enjoy and live through this totally terrifying experience.
The sound is terrible on these videos, it sounds like there's something covering the mic.
Who is the instructor?
The gyroplane has it's blades twisted downward 1.5 deg, where the Helocopter has it's blades twisted UP the oppposite direction from the gyroplane.
I am sorry, but a gyro rotor has its blades pitched up between 1-2.5 degrees, UP not down. Your name says it all, you would come a buster, correction you wouldn’t even get airborne, as your rotors wouldn’t even spin up. Man don’t comment unless you know what you are talking about.

Why can't this guy just shut up and listen instead of the constant comments?
This is worst kind of student. Did some reading ahead of time to show off. Won’t listen.
Nightmare student LOL.
So Mr. Weeks have you had any prior flight experience? LOL
Kermit, for shame... How long in the aviation industry and can't spell autogyro (with a Y)? You must live in central Flerda (Florida). ;)
Hmz, makes me think his "autogiro" needs "tires", whereas our "autogyro" could do with a set of "tyres"... Ah well...

Kermit assumes he knows more than anyone else. He should be a student and let the instructor explain.
Thank You! YES
He isn't assuming, he's asking informed questions and interacting with his instructor, which is the best way for a smart, educated person to learn. Do you not realize the immense level of his aviation experience and knowledge? He doesn't need a three hour lecture geared towards the dumbest common denominator of student; just getting to the relevant part.
Let him talk!

Kermit just learned more in 15min than you would have taught him in 2 hours. Don't try to fit him to a typical uninformed student's mold.

Was hoping to learn a few things from the instructor, but seems like the student talks more.
GO SEE AUTOGYROGIRL KERMIE, SHE'S CUTER :-) HAHAHAHA
