- New Design Front Intake Valveless Pulse Jet (Proof of Concept)
Showing the one way front air Intake and one way rear Exhaust Out Flow which is unique to this VPJ design. The next stage will be to incorporate thrust into this design.
How sad to hear that this gifted engineer has departed this mortal coil. RIP Sir.
When I was in my teens I made and flew control line all wing combat aircraft. Fast n furious fun.( & dangerous) However I had a pal who made speed record c/l planes with metal skinned construction and assymetric design powered by 2 stroke glowplug engines with tuned pipes (expansion chambers). These were blisteringly fast and flew on a single torque line instead of two.
Later when we were at college he became a good engineer and as a project he built a 14" long Pulse Jet which ran well. He installed it in a design out of a 1960s 'Aeromodeller' magazine that he'd found and blown up ( they had pics if plans reduced to fit in an A4 page!) Almost completely made from aluminium with tiny stub wing on the right, and a tapered high aspect ratio wing left. The pulse jet was strapped on top of the concave fuselage. It looked wild flew on a monoline and did some ludicrous speed for a model flying in a 90 foot diameter circle! In excess of 140 mph!
Seeing these videos brought it all back. I'm almost 60 now but the idea of putting one of Kunis valveless pulse jets in an ultralight aircraft and flying it, makes me smile.
Looks like the planet has lost a gifted experimental engineer. So sad. He doesn't even look that old in these videos! Condolences to his family and his friends.
What amazing work! So sad to find out such a creative genius has been lost.
When I was a kid in the 50s we had a Eureka vacuum cleaner that look just like that. As a matter of fact, it was just as loud and sounded the same when it got a candy wrapper or straw caught in it.
And while humming it also spewed flames?
It was probably an Electrolux. We had one too! 😆
@@tempname8263 only after Christmas, when you were vacuuming up pine needles and tinsel.
@@OhMySack By golly, you might be right.
Here's to a good recovery mate! I just came through sepsis. New heart valves, 40% kidney function & lost my legs but I'm out the other side & slowly 'waking up' again. ( That's what it feels like ).
At first my interests disappeared, I was happy just to be here. But now, bit by bit, my old way of thought is returning. Ideas, hobbies etc.
It takes time so don't be freaked out if you just seem to have lost old ways of thought. It comes back.
That's the best advice I can give you, relax, give things time. Recovery is more than just physical.
Hope this helps, I've subscribed & I'm looking forward to seeing this beast fly! ☺️
You didn’t see the comments that he died, didn’t you?
@@topsecret1837 No! Oh bugger! Awful... Thanks for telling me.
Best wishes to you being healed from cancer!
What is going on inside of the engine? I hope you can upload a video of the pulse jet + ram jet sometime, looks sweet!
Excellent work.....
So sorry to hear of his death ..
You have my condolences...

if youre still around go vegan. do juices of cabbage and carrots or those really fancy fruit smoothies from superfoods that have high antioxidant stuff in them. i was with big pharma poster child for 15 years. they dont know what theyre doing but they do organic veggies in their cafeterias. fortune 100 fam.. one of the reasons we broke up since i couldnt stomach animal and human experiments theyre into... veganism works. look up gerson. ruclips.net/video/eqhNLHlqrX8/видео.html tho you dont have to go as radical. 2 litres of boxed orange juice a day should flush your system from cancer in like 3 weeks with strict no animal based foods as meat, fish, dairy with lots of i.e. salads in a bun, like ordering only salad in wrap from kebab store, no milk based saouces, if youre in city. plenty of vegan replacement these days. look up cancertutor.com on related news look up ruclips.net/video/oJfBSc6e7QQ/видео.html and ruclips.net/video/J2uuOGvrZf4/видео.html
Well, how are you doing ? A guy in the states used worm medicine for dogs and fully recovered. 🤪
Just found your video. Great stuff.
@@pleasanthacking Horrible advice. Listen to doctors, not random internet comment advice. Cancers feed primarily on sugar. Orange juice, being high in sugar, is cancer fuel. There are various recommended diets to fight cancer, antioxidants don't play a role in cancer, but lowering blood sugar does slow (not stop) growth.
are you ai commenter? all know that antioxidants fight cancer..

Damn, dude. I'm sorry to hear that. I hear it more often than I can stand.
I so much wish you the best.
You got my support in the fight. 👊💥
So sorry to read that Kuni passed away. He had a passion few get to do.
Link?
Saddened to hear of this engineer's story r.i.p respect to you sir
May Gods Blessings be with. Really enjoy watching your work
Annyira sajnàlom , egy kreatìv okos ember ès a sors tèged sem kìmèlt. Ilyet olvasni kegyetlen szomorù! 🥲
Get well.
Think that white light is pumped from your mind to your lungs.
Or from your hands to your lungs
Do it for 10 minutes at a time.
Your design is good.
Cheers
Very Sad to hear that last bit of news. May the Force be with You also !! Now about the pulse Jet You built. AWESOME !!!! It sounded like a good ole 2 stroke ! Great Job ! 😎👍👍👍👍💜💜💜💜
I bet your neighbors are thrilled at you work!
I know its part of life but some people touch your senses. RIP, sir.
Lovely engine, Karpavicius!
Fight on!
Good job, looks cool too, thanks for sharing
I hope you are well now. Good luck, thanks for your teaching. Regards from Spain.
Hope you are doing well.. best thoughts.... nice pulse jet (best yet) good job!
Thank you for your kind words.
Are you still with us?
Unfortunately no. Kuni died 30.03.2019
@@callmeadmin RIP experimental designer
@@callmeadmin [sad eyes]
That's very sad to hear !
No, that sucks I had just found his work and it was amazing. Thank you for keeping his memory alive.
Rest in Peace Kuni 👊🙏
Fantastic design!
Smoothest pulse jet I've seen so far on RUclips! 👌👌😊
@@dumdum1559 Ooops! Corrected. 😉
I hope there’s plenty of room for your projects up there man
Hope that our Lord Jesus has extended your life as He has for me. I had stage 4 lung cancer and a resection this past Jan. and am cancer free. Praise the Lord. A great home built pulse jet engine.
He died.
@@MrBenski81 Very sorry to hear this. My condolences please to the family.
AWESOME DESIGN!!!!!!
good start for a potentially great technology!!
I hate to see someone that’s deeply passionate about a project get so rudely removed from their work. They never get the satisfaction of finishing it. Very upsetting.
Id love to see more on this.
Nice fab work!!
+MrBen527 Thanks MrBen, almost as good as the fab work on your pulse jet. Also maybe one day with a little help from above i'll be able to match the thrust on yours too. Keep up the good work.
Sorry to hear about cancer, get well soon and continue.
Other commenters have said he passed away in March 2019....
1:25 - Rear Exhaust is hot :)
Great Pulse Jet
Maybe one day some clever guy will invent a damper to reduce noise levels for pulse jets, and they might be interesting for Ultra lights,
No moving parts, easy maintenance
Hope you're well today! I'm curious to see this genius pulse-ram engine idea working!
Thank you for your kind thoughts. My disease is being contained at the moment and life is good apart from the 4 weekly dose of chemo. I have made a stage two model which is nearing completion and I try to do a little more on the project whenever I can. We will then see if it is genius or not.
been waiting a while to see if someone would make one of these. hope you get well soon.
I believe Kuni passed earlier this year.
@@edwardsp1916
sorry to hear that. :(
Only he will know the "how to." RIP Kuni.
Thats really cool....
Nice job... I wish you all the best....
God bless ole buddy and good luck I'll be praying for you!!!!! God can heal you if you only trust and believe with all your heart mind and body and love him just the same ! Again I'll pray for you my brother !
Best wishes and God Speed your recovery.
Loud ass BBQ grill you got there
Damns that a nice design. Would have loved to see the ramjet in action.
@@dumdum1559 Did you actually watch the video all the way though?
I love it. Reminds me of Wiley Coyote.
Rest in power Kuni
Wonder how his neighbors feel about all of this? 😂
It was a tradition in London to raise a glass every time you heard an approaching V1. This is why Londoners referred to them as "buzz bombs".
@Steve Thompson It's people like you that take all the fun out of world wars.
Awesome🍀
now my friend you can travel at the speed of thought......fair winds and following seas, dear Kuni.....
Your engine looked most promising and I hope you are recovered and doing well enough to continue with it one day and no doubt the many other things you had in mind.
Best wishes.
I like the aerospike.
I wish you a quick recovery Kuni.
Sadly, he passed March 30, 2019.
Hi Kuni! I hope your recovery is going great! I have wanted to build a pulse jet since my senior year of high school 3 years ago and am finally planning to take a shot at building one in a couple weeks. Do you have any plans or information from your research that you would be willing to share? Any advice would be much appreciated!
I started with a basic valveless design and found that threaded metal water pipes was the easiest way to make this because I did not have access to a welder. I started with a 200 x 90 mm combustion chamber (pipe threaded on both ends) on to which I screwed threaded reduction fittings (both ends) which reduced the diameter to 25 mm (internal threaded size.) Into these I screwed a 50 mm long threaded inlet pipe and a 500 mm long threaded exhaust pipe (both 25 mm dia.). I clamped a thin copper tube bent into a "u" shape onto the inlet pipe with one end poking down the pipe and the other end attached to an LPG outlet. I clamped the whole unit firmly in a vice in a well ventilated area free of combustible materials or fumes. To start the pulse jet I placed a lighted fireworks sparkler in the combustion chamber turned on the LPG slightly and blew fresh air into the short intake tube with a leaf blower or compressed air. This usually took a few tries until the unit warmed up but when it did the first time it almost deafened me as I was not wearing any ear protection. Well that's how I started in 2005 and it has progressed from there. Thank you for your moral support I hope that you may find this information useful.
Kindest wishes. From Duncan.
Respect!
Jeepers, didn't know fking lung cancer got the better of you. :(
Cheers to you and all your experiments......
Cheers!. :)
Mick
Godspeed, my prayers are w/you & family/friends. :(
Best wishes to you
Hope all is well!
Is it me ? , running a pulse jet with so much combustible material around a good ide ?
Jan Tschierschky me hear to
Light that up in my garage? Not a chance in hell
Its beautiful! Did you take it beyond this point?
God bless you.
Rest in peace great inquisitive mind.....sad to hear u have passed
Interesting. Hope you have good fire insurance!
I have always wondered if a valveless pulse jet could be made using a Tesla valve for the intake.
That's a good idea.
I was under the impression that pulse jets were the reason Tesla came up with that valve type....
@@lordchickenhawk I think jets came along 30 years later
Some guy on RUclips did that, but he tried it with 3D printed parts!😅
Needless to say, it didn't last long. It's a pretty funny video.
I don’t know if a Tesla valve works for pulse jets, but I can say I’ve seen that question a LOT. I think if it worked well, we would have seen it many times on RUclips.
My guess is the intake restriction outweighs the benefit of exhaust restriction, but I’m no engineer.
Uses the washington post to check the exhaust lol lucky he never burned the shop down lol
Neil Macleod He could probably use the Washington post for fuel
The only difference between a ramjet and a pulse jet is the ramjet tends to have a shock cone intake.
So it seems you made a ramjet.
But i dont know exactly how you made this so i could easily be wrong. But kudos man! And best of luck to your battle!.
Get well soon
15.10.1945 - 30.03.2019
What no full power test inside the shop?
Great job! Do mind telling how the intake works? Is it similar to a Tesla valve? I hope your treatment is going well!
I' ll let my family evaluate the technology and let them decide what to do with the design in due course. There are no similarities between this and the Tesla valve. Thank you for your good wishes. "Don' t count the days, make the days count" (Mohamad Ali)
Good luck with your medical problem, will pray for you mate
Sadly, he passed March 30, 2019. Nice of you to try to be encouraging.
Nice sentiment, but sadly praying doesn't do shit.
I prayed for two separate people in my life who both had cancer around the same time. Unfortunately, the prayers fell on deaf ears (as always), & they are both no longer here. Since then I've come to believe, there is no God, & praying is a waste of time.
But that's my opinion.
@@mickmuzzmkmz1628 I also have severe doubts about the efficacy of any kind of prayer, however, there are others who believe in their power, and we must respect others if we expect others to respect us. Peace. At the least, prayers, however ineffectual, offer a measure of comfort to the believers in sad times.
@@michaeldesira1998 Fair enough. As long as the JWs stop knocking on my door, I don't really care. 🤣
Tiny amount of further compression (just let it move) your there😎
I hope you are doing well.
I'd like to see what happens when you mount that device to a vehicle and get it up to a high enough speed that a ram scoop effect could affect the operation.
If it gets put on an aircraft, that will be a big factor.
it burns surprisingly clean , no flame to see , how much thrust does it generate ?
If you watch my first video NEW DESIGN FRONT INTAKE VALVELESS PULSE JET and read the comments it will answer your queries. Thank you for your interest.
Yep we covered it! We’ve seen a thing or two..
How very interesting
Liquid silver and MMS.... if you have cancer to last-ditch effort..... nothing to lose....... I'm doing a bucket list...... best of luck my friend
You have plans for this beauty
Very clever! Well done! Will be praying for your speedy recovery from lung cancer mate, if you've not already won that battle?
Fascinating little pulse jet. Interested to know how much thrust is generated and overall power efficiency
Very little.
@@larryscott3982 yeah, it didn't look like it would move a brick
Good luck with your health!
Where do you put the twigs in to cook your noodles?
It's like a ram jet that does not need motion
Any news of the patent? Would be lovely to recover the hard work and continue development of this concept.
I hope you beat it!
thank you
God Rest Your Soul, Kuni.
could you please show the front air intake a little more
Are you using a modified Tesla valve at the intake?
So sir any updates? We are all waiting, hope you are back in the shop. We want to see the 1K model!
Chemo every three weeks has put a damper on further progress. Am waiting on possibility of a remission before I am well enough to proceed further with the 1K model. Thank u for your input Don.
But does it create enough thrust to propel it's self?
Sad news! But get well soon anyway!
How to wake your kids up in the morning...
He held the templates with him ;-; faaaak
Rest in Peace Kuni! Cancer is an asshole. 😪
The fuel goes in the front not the middle or rear, also the front intake needs some welded on stationary tilted blades on the intake to give intake the turbulance needed for thrust power and velosity to increase proportionally with oxygen intake increase otherwise you just keep blowing out the God Damn candle. Tilt those stationary intake blades on a swivel and tune it for power like you were tuning a carburetor. Blades can be vertical or spiral but must be tuned for the volume going through it, a set of 4 wings inside the front will create enough turbulance. They have to be a wing foil shape for correct turbulance and thrust. They may swivel to create full or no throttle off. Bolt down unit as it will fly away with table and all attachments. AND A HIGH PRESSURE BACK FLOW VALVE , HIGH PRESSURE , BACK PRESSURE VALVES MUST MUST MUST BE IN PLACE IN STEEL FUEL LINES. REMOVE SPARK PLUG AND HOLE, IT WILL BE BLOWN OUT. Do not blow yourself up as high back pressures can travel to your fuel tank if not protected by high pressure valves. Be very carefull your valves are rated for the high pressures and tested and failsafe two in line, it can and will easily blow up if they fail. This is not a toy, you will eventually get it right, I just want you to know the right way before you blow yourself up.
Noted. Thank you for your input.
Hola saludos desde colombia.hay me suscribo a tu canal
Has anyone shown this video to @Colin Furze? Could give him an idea to have a go at making something similar.
Is that spike tip at the air intake supposed to be vibrating like that?
No. Damaged during transport and bad welding.
+Kuni Karpavicius Where'd it come from? China?
My welding is not that bad. Had to take it a long way out of town because of the noise and fire restrictions here.

You can believe what u like but its the truth. May the force be with you.
I don't think his insurer would be happy to see him testing a device that gets as hot as 800 degrees F in the middle of the fire trap that is his garage!
Just like the v1 rocket in ww2
