RedBull Flugtag in Chicago September 2013
The 2013 Chicago Flugtag was one of five simultaneous events happening on September 21, 2013! Actually the world record was made at a distance of 258 feet in Long Beach California that day. Let's see what entries from Chicago can produce. These homemade planes are the brains of many individuals and groups. Do not let their costumes fool you.
Thanks for all you efforts to entertain us and the personal SHOUT OUTS to TomsAviationWEB.
Check back soon for full 100 minute HD video...once I get things settled with RUclips.

Things helicopters are not suppose to do....again and again and again. Flown by Chuck Aaron, the first and only civilian pilot ever to be licensed to perform helicopter aerobatics in the United States.

The only pilot to fly 100 mph forwards and backwards. Watch all his moves, very impressive.

Great view to watch the Harrier perform at its max. Incredible noise, thrust and speed. Thanks to Nalls Aviation
Jetman Yves Rossy at EAA Airventure 2013
Просмотров 12 тыс.11 лет назад
Yves Rossy flys with only a wing, 4 small model jet engines, an altimeter and a throttle in hand. There are no mechanical connections that provide movement to any part of the wing. He controls his flight by his body position! First US public flight - I was a witness to aviation history...where will we go from here? FYI, he controls direction of flight with only certain body movement.... Spottin...

Patrick demonstrates for TomsAviationWEB and its viewers the main concepts of how a Pratt & Witney Engine works. Patrick is not a vendor but nobly contributed his knowledge. Thanks Patrick.

What type of oil tank is it?? .Wet sump or dry sump?
We are developing an advanced, ultra-efficient, low cost, power dense turbo-engine to power our personal air mobility platform - the PersonalJet©
Thanks for your nice explanation clip - "Happy Landings!"
This Jet Engine (PT 6 A ) Is Best ( Power Output, 97 % ) Very Savety To Used For Flight Engine ( Include Commercial Jet Plane ) , Appriciate To The Produsent Industry, - God Bless All, - Thanks All, ..... Cheerio.*****.
Asian voices in the background are hilarious
Too much background noise
Would rather have you keep the camera on the chica... butt, whatever
The PT6 originally developed in the 1950’s is assuredly off patent. Why hasn’t another company started building one?
This is exactly how I was taught as a mechanic. Great explanation.
Power ?
Great video
Mereka Ku
wonderful engine
Excellent bro
Great
It's genius is the non coupled hydrostatic transmission..Allowing for better efficiency. As the rear part is not coupled to the propeller input shaft.
Free energy compressor AIR=GAS engines.
Wow very informative - thank you!
Would love, if AviationExam would have explanation videos like this instead of the endless novel-like copy-paste “explanations”. Literally everyone could finish with ATPLs in half time.
Its a question database and no oxford literature
Aviation Exam comment section brought me here ;) Thank you for the video
Great video. Thank the chick in the chair for me.
Didn’t define “free turbine.”
Means the turbine is not connected to the compressor (hence the opposite turn rotation)
@@maxvandyke1831 Yes, I know what it means, just pointing out that, at the beginning, he’d say what it means but never did. My airplane has single shaft turbines, quite different.
Harv's Air brought me here!
Aaron is a beauty
Same!
Hey where can I get one of these FREE turbines?
Finally someone who explains this.. gees. Its soo hard to understand if this is your first turbine you are flying
That’s one superior engine right there!
Do a Garrett [oh excuse me, Honeywell] 331 and explain why they are so much better.
Better in which way, SFC, Shp, TBO....ease of maintenance, time in wing, modularity not cost?
Had to rewind, kept staring at the hottie with the rack!
Please explain to me how the propeller interface unit, from where it's located, can change the angle of the blades on the prop to slow down its rotation? In your video the PIU is in front and on top, but there is no propeller. If the prop was there, and if it was turning, how in hell are the blade angles on the propeller changed from where the interface unit is, without a mechanical linkage of some sort?? Just asking... good teaching video , i enjoyed it.
He never got to what a free turbine is. Front and back are independent of each other. Not connected. I did not realize that part of the hot section is connected to the cold section, and that the power producing section reverses rotation. I wonder if there is some advantage to that reversal?
Nice rack at 4:47
Even nicer rack, and legs, at 0:01. In my opinion.
Fantastic Engine
I understand everything (pretty much) except for that unit near the end that he say controls the rotor rpm. I would have thought would surely only be controlled by the turbine/compressor shaft speed entering the planetary gearbox? Also, the compressor side does not compress incoming air by having it go through smaller spaces. This would have been a good place to give people a brief description about how axial compressors compress air with the stater blades increasing air pressure from the rotating blades giving air increased velocity and that velocity is transferred to pressure by the stater blades (well that's my understanding of how the compressor section works anyway)
It is called a governor, and it changes the blades AoA (finer or more coarse) to increase or decrease torque, which in turn matches the rpm to the desired input. Turbine prop jobs have variable pitch props to increase efficiency (by matching prop AoA) for optimal performance
@@maxvandyke1831 Thanks Max, that helps me get some more terms to look up to increase my understanding. It's hard to learn this stuff without knowing the terms to look up.
Beautiful model Very nice presentation Cutaway model cleared many doubts Thanks for the video
Thanks so much for such a lucid explanation
Good model to make Digital twin of GT
Which end goes up his ass? Or does it go in sideways ?
Now, at last, I understand a lot more about turboprops. Brilliant, and thank you.
Stopped watching at 1:22... I was waiting for the "very knowledgeable" presenter to describe some part of the turbine as the thingy. The PT6 engine is one of the most used engines in turboprops in the world.
Pma means permanent magnet alternator = power for fadec and prop control
Probably the best thing you can do with ~$1M. Spend the change on some kerosene.
this is what both GE and pt have decided obviously..85% of propulsion comes from the prop in convention turbos.. theyve decided to increase that and decrease the turbo gas 15%... theyve ELIMINATED the ultra HOT section..ok thats good.. makes engines last longer.. but they AINT getting 110% of the same power.. theyre getting 95% and an engine that lasts 2000 hours longer per overhaul..ok i can understand that
the rest is hype
ahaha ok the greatest minds in the world built this eh..ahaha reversed airflows, counterrotating veins.. reduced space.. yall are nuts... in fact counterrotating veins is a lot more complicated and problematic..someones drinking too much aviation koolaid
a reverse air turbine..how silly
Its important to reduce after take off Throttle before Rpm or never mind ? and why?
When you reduce rpm, the torque will increase. So just keep a close eye and don't over-torque the engines. If you are close to max torque for takeoff may need to reduce power slightly before rpm.
Torque and engine loading are used in aero parlance incorrectly.When you say 'over torque' you mean overload.Any machine that generates rotary motion (torque)can be overloaded.In gas turbines as in piston engines there is an rpm which gives mamimum turning force or torque.This is usually best speed to run the engine at.The propeller is the load and as most propellers are run at most efficient speed(a constant)engine load is therefore determined by blade pitch angle.Sudden change off pitch can quickly overload (over torque)or unload the engine.These sudden conditions changes are to be avoided in normal operation.Engine loading is usually kept constant by the automatic pitch control unit.
how much would a pt6a-21 set you back?
100k
that's not too bad some of the new piston engines are that much
Yes.. and how many of them give you around 750 to 800 hp ?
I thought the 21 had 550 hp?
A -21 is crap. it’s on King air c90 only. They cost around $300 to $450 new.
So its like an automatic transmission for airplanes, torque converter and everything
Nice engine. And nice tits too.
Hey there! Great explanation buddy thank you very much. I need to do a PT6 Starter Generator course to improve my knowloge about it and certificate. Any course sugestion? Thanks alot!
Excelent, thank you. Cheers from Mx
