Congratulations. You are the first person to explain how a helicopter engine works in a way that my brain can absorb. Now I'm gonna run around pretending I'm clever and know this kind of stuff. ;)
Very tough question. The free shaft is basically the replacement for the high speed section of standard aviation. Providing your bearings do not seize up, and you don't jam the throttle any turbine engine is good. Heat has always been a problem. Application is the subject to answer what you're asking. Purpose is everything!
It's all good here. I am in the process of manufacturing my own engines. My first prototype is nearly complete. Most people don't even care. It's all about touch screens and drama on tv. You learn by asking.
I also very much enjoy hearing like RR allison 250 and the P & W PT6 gas turbo shaft types these engines are quite an old design but proven types thanks for making this video
I've just started flying helicopters and my trainer is a Bell 206. This video has helped me understand a lot. I only have 8 hrs total time so helicopters and turbine engines are all new to me. Thanks for sharing!
@@HelicopterTrainingVideos Great! This was a long time ago. I'm a UH60 Blackhawk pilot now with some amazing life-long memories. My favorite has been my time flying humanitarian missions in Central America. Very fulfilling. My longest cross country flights in a Blackhawk were from Fairbanks, AK through Canada to Kentucky and another trip to California. Great views when the whole route is flown at about 300' AGL.

Your video was concise and full of solid information to get me back on the path! Thanks man! Did you just finish Commercial and did some Turbine time? Or were you doing something else with LEA?
@@unknowkskills87 Congratulations on the Tour gig!! Probably a bit slow right now with COVID I imagine? Nice to get into an R66 - not flown one, but have friends who all like it. I did turbine and longline training thinking it would affect my job opportunities. For my path it did not, as my next job after instructing was in EC130s and AS350s in the Grand Canyon and they give all new hires full turbine transition training. It was a (expensive) blast though!
One of the coolest sounds...but the coolest it the melodious rhythm of wop wopping rotor blades - embedded in the full throated growling roar of the turbines. Business in action transitioning to poetry in motion!
In the Bell 206 it is at the top, behind the main rotor mast - google search "engine compartment bell 206" and look at the images. I'm not sure I understand your second question - the front blades of a turbine are compressor blades - they pull in air and compress it to be used in the combustion process.
how exactly is the engine placed in the helicopter . And in some the front blade of the jet engine is used to spin the the helicopter blades is the mechanism same in all helicopters?
It is not too dissimilar to the layout of an Allison 250 C30 used in some Bell 206s. Search google images for "Allison 250 C30 Engine" for a nice color-coded diagram - the layout looks almost identical to the one used in the FAA book.
Comment from Mike Franz: Just watched your turbine engine video. It is well done but you label the fuel nozzle and igniter in the reverse positions. It is incorrect in the FAAa handbook also. The upper is the fuel nozzle, the lower the igniter plug. During preflight you can follow the fuel line to the rear of the burner can and the igniter lead from the igniter box to the plug.
good day, first of all great video, but one thing I've noticed, you have marked the injector and igniter in the wrong way around, injector would be centre of the combustion chamber. Thank you
I saw the tail number on the helicopter (N319CF) and I thought it looked familiar. So, I checked my log book, lo and behold, I flew that same helicopter for long line training. Then I thought to myself... The person who made this video sounds English and has flown the same helicopter as me...hmm...who could this be? This person could only be Eggy Toast! Great video and explanation of how helicopter turboshaft engines work.
Eggy Toast! Im doing good. I worked as a sub-sea remote operated vehicle (ROV) pilot for a few years doing work on sub-sea oil/gas machinery in South America. (It sounds cool but, it was super lame) I am going to school full time, working on a bachelor's degree for UAVs. I talked to River a few weeks ago. River got a full time job (40+ hours of flight time a week) where he lives, doing helicopter logging/areal firefighting as PIC in a Bell 206L4. He got hired with just over 500 hours of PIC for that job! He said his job was a " right place, right time" situation. Pretty cool! Also, with current flight ratings, you can go to www.faasafety.gov and get a commercial Part 107 UAV endorsement on your license by clicking though some power point presentations. Its super easy, like an hour to get though the presentations. For an hour of your time, you will get an endorsement to fly drones commercially! How are you guys doing? What are you up too? I have not heard from Charles in a long, long while...I bet you have my email address somewhere in the archives of your inbox.
I have been searching stereo sound of helicopter flown overhead fast in Internet for free for couple of years . Would you refer where i could download sound that starts this video ?
What I understood from your explanation is that turboprop, turbofan, and turboshaft are using the same turbine mechanism, which the thing make different is in the connection to the fan/propeller. Turbofan is connected to a ducted fan, turboprop is connected to a propeller and turboshaft is almost the same with the turboprop but turboshaft is connected to a rotor. Am I correct?
The only thing I'd add to that is that the Fan in a turbofan is freewheeling and the shafts in gas turboshafts go through a free-wheel unit to ensure the rotor or prop stays moving even if the engine dies.
Why is the combustion chamber behind the turbine on this engine? Cooling of the combustion chamber? And why is the turbine called N1? I'm used airplane turbofan engines on airplanes where N1 is the fan.
+Nick M I have no idea why but if i could guess it would be so that the fuel/air mix has more room to expand. by rooting it backwards and stuff they allow for more expansion witout making the turboshaft really big. But im only 15 so what do i know lol
The rotors/ reduction gearbox or power takeoff is from the Lo turbine (n2) and NOT from the Hp turbine!! Engine ( gas generator) will continue to run with no unnecessary clutch!!!!!
+jugosever I have been told steel would melt and titanium would oxidize too quickly so the answer is usually nickel alloys or ceramics. You'd have to speak to a manufacturer to get the specifics.
hastelloy , nimonic, inconel alloy steels very hard to work with cutting tools , usually are casten by investment casting then refined by 5 axis mill & grinding machines , radiographic control and more...,electron beam welding of the hub in some cases
The First Turbine Engine Helicopter was made in France by aerospatiale namely eurocopter and now Airbus helicopter The Engine was developped by Turbomeca and now named Safran Group The First helicopter in the world using the Turbine Engine is the Alouette 2 and the prestigious Alouette 3 and also the Lama Helicopter😎🚁🚁🚁🚁🚁🚁🚁
Why those engines are not liquid-cooled ( more weight, but smaller parts of turbine, and better heat exchange efficiency )? N1 and N2 could not be used as contrarotary sections of inlet compressor?
Did he say in the video that they aren't liquid cooled? I was of the impression that at least some parts of them are liquid cooled, but I could just be thinking of the lubrication system.
+Chris Karpos Yep, very close. A turbocharger is essentially sorta like a tiny turbine engine with a piston engine shoved in between the compressor and turbine section. The thermodynamical difference is that a piston engine extracts all of its useful power from the gas flow before it reaches the turbine section, whereas a turbine engine either uses another (power-extraction) turbine section downstream from the turbine driving the compressor, or the same turbine that drives the compressor also extracts energy to drive the load, or if it's a turbojet engine, there is no more energy being extracted from the gas flow, and it is instead accelerated in a propulsive nozzle to provide thrust from the engine. Frequently turbine engines use a combination of several of these propulsive methods. For example a GE CT7 turboprop engine has a free power turbine stage downstream of the gas generator turbine to extract power to drive a propeller (which provides the bulk of the thrust from the engine), but any residual energy in the exhaust is also accelerated in a narrow exhaust duct and accelerated rearwards to provide a little extra thrust and propulsive efficiency.
Yeah well we're still using feet and miles when the rest of the world has metric. Do you know what a bitch it is having to buy SAE and metric tools? Some cars have both. It's maddening!
Why do helicopters use turbine engines rather than say... a piston engine or something. I feel like turbines would be slower to react to power inputs than a piston engine? And I feel like if you have a CVT gearbox, you could start up a helicopter quicker, and you can "horsepower" your way through a heavy load because you are mechanically linked to the engine rather than having the gases from a turbine engine to use for power. I'd imagine power inputs are "spongy" with a turbine, slow to react and stalling out is easier.
Piston engine were originally used in helicopters during the 40's. However it was found that piston engines needed mores space and were much heavier. And pistons actually took a longer time to start up. I think you still get some piston engine helis but they are rare. Turbines were preferred by the US military during the Vietnam war and they contributed greatly to making the UH-1 a very useful tool to the military. Ever since then, its just been very common to see turbine engines.
turbines give a constant power flow. this is needed for a rotor system that dose not change it's speed, only the angle of approach. IE the blade can change it's pitch (articulation) where an airplane's blades do not change the position of their wings. I recommend checking out a rotor head video as well so understand the principle better.
You don't need the turbine to change speed quickly when you can adjust the pitch of the blades themselves to alter their lift characteristics. Turbines offer a great power for their size too.
Turbines are also much more reliable than piston engines, have less moving parts, and get less wear and tear. They're also pretty cheap and easy to build from scrap, but let's not get ahead of ourselves
+dranzer gigs As the compressed air/fuel mixture burns it expands and creates the momentum needed to turn the turbine wheel. The turbine wheel is connected to the compressor, so it also turns the compressor. The compressor provides more air for the burn to keep going, turn the turbine, etc. This may not be too intuitive and may sound a bit like an impossible "free energy machine" (turbine is powered by air that was delivered by the compressor, yet the turbine itself turns that same compressor). Bear in mind though that it is the fuel burning that inputs the required energy to keep this going. Also, before all this is going on, an exterior starter motor turns the compressor+turbine until the engine has sufficient RPM to sustain autonomous operation. It is then turned off (or in some cases reverts to a generator use).
This is all very basic simple theory and understanding that any pilot would know so why do you feel the need to show that you understand this?? I don’t !!!!

This presentation is clean. The engine diagram shown looks like a very simple engine. Better than most common dual shaft set ups.
Very tough question. The free shaft is basically the replacement for the high speed section of standard aviation. Providing your bearings do not seize up, and you don't jam the throttle any turbine engine is good. Heat has always been a problem. Application is the subject to answer what you're asking.

didn't the exhaust gases have also kinetic energy which could be used for more torque?
I guess not enough to make any real difference - the energy has already been 'harvested' as they went through the turbines.

This model uses an electric starter/generator
larger models like the CH-47 and UH-60 use an APU for bleed air starting as well as additional electrical power to start their mains.
Is there any kind of clutch assembly that can/has been engage/disengage the rotors but keep the engine burning?
