General Motors Presents the ABC of the Gas Turbine. This is a 1973, color film created to explain the many benefits of the gas turbine engine, its many uses and efficiencies.
The film opens with footage of a Wilesco toy steam engine. Heat energy from the burning fuel is converted into mechanical energy. The expanding power of steam drives a piston and rod. This is demonstrated with an animation :47. The rod creates rotary motion and the cranking action turn shafts and wheels. Rotary motion can also be achieved by taking steam directly out of the boiler and directing the steam at wings on a wheel. This is shown via animation 1:11. This converts heat energy into mechanical energy. The example given is an external combustion engine with the fuel-burning outside 1:28. Gasoline and diesel engines are internal combustion engines and are displayed in animation 1:36. In these engines, internal combustion is combined with direct rotary motion 1:53. A bladed wheel air pump turns due to the heat exhaust from the internal combustion engine 2:16. The process begins with the intake of air, then compression, then power and finally exhaust. This is a centrifugal of engine 2:35. Some engines use an axial flow where the air is drawn in parallel to the axis of the shaft 3:00. Again the rotating blades like those on an ordinary fan accelerate the air adding velocity 3:15. Stationary blades decrease the air raising pressure 3:25. A fuel nozzle sprays the fuel 3:39. A spark plug fires, igniting the heat source 3:55. Shaft speed can be as high as 50,000 RPMs 4:20. This engine is virtually free of vibration 4:41. The gas turbine has many useful applications. If you taper the exhaust pipe so that it acts like a nozzle and speeds the velocity of the gases, you have a turbo jet engine 4:49. Turbo jet components are easily recognized. Compressor, combustion chambers, turbine and tailpipe 5:17. An actual jet engine is shown 5:22. A balloon is let go and flies by reaction. When the stem is held closed, nothing happens 5:50. In this case the air inside is pressing with equal force on all sides and in all directions 6:05. Animation illustrates thrust. A rocket takes off from a launchpad 6:41. Reaction makes a thrust reverser work on a jet engine 6:57. The thrust opposes the forward motion of the airplane and slows it down 7:15. Some turbo jets are equipped with an afterburner 7:25. The fan jet is a turbojet with modifications 7:45. The fan pushes some of the air coming into the engine to the sides and reactive thrust is produced 8:00. Second turbine is added to drive the fan 8:07. The gas turbine can be combined with a propeller creating a turboprop 8:42. An actual turboprop engine is displayed 9:08. A gas turbine is displayed 9:15. It is usually called a turboshaft engine. These engines can be found in trucks, buses and heavy equipment 9:35. Animated feature shows a gas generator with power turbine and a speed reduction gear that drives the load shaft. It has gears, hydraulic clutch and torque control 10:13. The clutch can be operated partially engaged or fully engaged 10:35. In the braking action, the clutch is fully engaged 10:55. A regenerator or heat exchanger is a flat disc of reinforced steel 11:07. The disc absorbs heat and improves fuel economy 11:33. The engines component include a starter motor driven by a battery that is kept charged by an alternator, a high-voltage coil for the spark, a fuel pump, a fuel control, an air pump supplying suppressed air, a torque control, and a control system that provides protection against the engine exceeding limits. A pump to supply oil to the engines shaft bearings and an engine oil cooler of the radiator type 12:30. A gas turbine engine is displayed 12:45. The gas turbine is making great strides as a versatile power source 13:25.
A gas turbine, aka a combustion turbine, is a type of continuous and internal combustion engine. The main elements common to all gas turbines are: (1) upstream rotating gas compressor, (2) a combustor, (3) a downstream turbine on the same shaft as the compressor. A fourth component is often used to increase efficiency (on turboprops and turbofans), to convert power into mechanical or electric form (on turboshafts and electric generators), or to achieve greater thrust-to-weight ratio (on afterburning engines).

I really love these old videos. GREAT STUFF! Thank you for posting all these.

Very cool video. I recognize the cutaway engines. They were in the Allison visitor center in Plant 3 on 10th St in Indianapolis. I worked at Allison as a college co-op from 1980-85. Occasionally on lunch break I would go there and study the cutaways. The turbojet was a J71, the turboprop was a T56, the turboshaft was a T63 (better known as a Model 250), and the industrial gas turbine was a GT404. Allison was a great place to work and learn about engineering. I did a little bit of work on all those engines during the time I was there. But since I was a co-op student, nothing in-depth.
This film was made when GM owned the Allison Engine Company, a leading aircraft engine manufacturer. Today Allison is part of Rolls-Royce.
Thank you for this context. I was wondering if I misread GM as GE for a second there. Makes sense with your comment.
They made the T-56 series which was the only engine used on the early C-130s and P-3s. I still remember the sounds working around the P-3s for a few years in the early 70. I have some time in that aircraft.
@@Chris_at_Home They still fly touch-and-go exercises on a regular basis at Moffet Airfield. To be on the frontage road at the right time is a treat.
Rolls Royce also have a connection with the French firm Turbomeca that makes small gas turbines for all manner of applications.
My brain used to work like this until I got old.
To the point and no childish crap to entertain the non interested. Excellent!
OMG! I had that exact model steam engine! ("Model" is kinda unfair, it WAS an actual steam engine, Just small!) The Fuel on mine was 110v AC heater in the "boiler" though, and YES, Of Course I burned my fingers once or twice pissing with it. It was an awesome thing though. I made it turn an old permanent magnet motor and generated power to light a little light bulb with it. Yay! a was a boy with his own steam operated power plant!, LOL. Been a mechanical and electrical "geek" since!
Just think if the Gas turbine Powered vehicles had really taken hold back in the 50's and 60's Where they would be today With the technology we have now
Chrysler worked on gas turbine cars from the mid 1950's until the late 1970's. The best known were the specially built turbine cars of 1963-64 that had a public tryout until 1966. (The earlier AND later turbine cars were "stock" Plymouths and Dodges fitted with turbine engines.) The development program was ended as part of the 1979 government bailout of Chrysler.
I'm guessing nowhere. There's to much inertial mass for quick acceleration and declaration. Ex. ever rev a gas turbine engine.
A very informative film about the principles of gas turbine engines.
Love that Jensen model 75 at the open.
That does it! The next time I need to buy a jet engine, I’m buying a cutaway one!
Great idea! If anything goes wrong with it, you'll be able to see EXACTLY where the fault is.
The intro music alone makes me want to watch this!
Groovy music!
Yeah man, it's far out!

Kind of reminds one of "Duel!"
GE could make a similar film featuring their successful LM2500.

Periscope Film, thanks for posting this. It brought back many memories.
A gas turbine truck...sounds like something Batman would drive.
at 9:05 that's the allison T-56 from the C-130. That engine was almost bullet proof.
And still in production today. It's the small block Chevy of gas turbines.
and the one right after is an Allison 250 / T-63
So good i had to watch it twice! Amazing video👍👍👍
Glad you enjoyed it!
The ABC of gas turbine
Always
Be
Cturbining.
I need one in my truck, I do a lot of continuous highway driving, it would be perfect for the application
All of this may have made sense before 1973 and the oil crisis
13:37 Is that a Rat Pack Mopar dusting the GM Super liner?
I never heard of a turbine powered bus. There were a small number of turbine railroad locomotives. Never caught on☹️
Dobré.
👍
Interesting film but I am surprised that they didn't cover the turbines naval application. I am pretty sure their dominant LM2500 was out by that era.
how does this work with magnets ???
It’s too bad it seems there aren’t more turbine engines. In automotive use at least. Do big trucks use them still if at all?
Nope.
Neither do locomotives anymore
Hydrogen Turbines!
He says _"turban",_ but he means _"turbine."_
I've always pronounced it "turban", but I'm trying to re-train myself to say "tur-BINE". Long I, not short. It just makes sense.
Short rifle: CarBINE or CarBEEN - Both are considered "correct" - Same here.
Dude completely mangled the explanation of the 'jet principle'. It has nothing to do with "balances in pressure". What's really going on is this: A mass 'm' of air molecules is expelled out of the hole at a velocity 'v', imparting a kinetic energy of 1/2*m*v^2 to the expelled air. Every action has an equal and opposite reaction, so it imparts an equal kinetic energy to the balloon itself in the opposite direction.
This is why rifles recoil and rockets produce thrust in a vacuum.
Sorry GoSlash27, don't agree. This is the first video which exactly explains the principle of jet thrust: it has all and everything to do with the balance of pressures. Of course, Newton's third law of motion is valid here and one can accurately calculate the thrust of a jet by the speed of the efflux. But the essence of the matter is the balance of pressure. See the comparison with a propeller: Both a jet and a propeller produce a high(er) jet of air behind it, Hence action is reaction. While in reality a propeller is a set of "wings" rotating around producing lower (air? water?) pressure in front and higher behind: purely balance of pressure
space is fake. How can you have "fire" (combustion) in a vacuum/"space"?
fire is impossible in a vacuum
