I *LOVE* how you included the "Suck-Squeeze-Bang-Blow" on the diagram, for someone who's very familiar with internal combustion engines and a keen interest in the high-tech engineering of high-performance engines, just including those 4 steps as having a direct equivalent within the turbine engine made this a lot easier to grasp intuitively. I'd always assumed that turbine engines must be superior to piston engines because there's no energy lost from the moving parts changing direction of travel with every cycle of rotation, but never knew exactly how they worked until now. I checked out a few short videos like this and have to say this was by far my favourite one, really well explained. I almost did a double-take when I saw your channel is just shy of 600 subscribers, watching the video I just assumed from the quality it must be from a channel with 5-6 figure subs. Awesome job on this my man, keen to check out some of your other content now!

There is another explanation, the compressed air/fuel mixture is ignited by contact with the combustion gases which makes sense. That's what I heard, it's not my thoughts.

Just one correction. The engine doesn’t let “air” out the back. It sends out “exhaust gas” which is mainly nitrogen but also CO2 and water vapour (combustion products). There is some excess oxygen but nothing like the amount to term the gas mixture “air”.

Dude, how uptight are you? Air is Air. Air is made up of gases. You can have variable amounts of different gases to make up "AIR". Depending if its filtered/processed, fresh atmospheric air, polluted air ( this would be your "exhaust", toxic air, hot air, cold air, humid and non humid (the last 4 mainly change the water vapour content) and the altitude of the air. The OP did not state the air state. Atmospheric clean air in, polluted exhaust air out. In his context, AIR is AIR.

@HitMeWith3 жыл бұрын
It's a great little fact! Typically the hottest temperatures are found in the turbine. This is because it is at the end of the combustion chamber, where the hot flames are most intense. The engine will actually take a small amount of cooler air from the compressor, and using various pipes, will route it into the turbine. It is then blown onto and around the various components. This cooler air is essentially able to 'blanket' the hot components from the intense heat! Hydrogen fuel cells is a great idea - I've added it to the list!

The analogy of the balloon is misleading: that is the principle of a rocket engine, not a gas turbine. The gases rushing out of the back are not what propels the engine forwards. In fact the greatest contributions to forward thrust are the compressor stages and the combustors. The turbine and the exit nozzle (non-afterburning) are rearward-acting components that push against the desired direction of motion. In total it is the excess of forward-acting gas pressures over rearward-acting gas pressures that produces a net forward thrust.

You mentioned the temp to be higher than the melting point of the metals that make up the engine. What happens is that the fuel air mixture is mixed in such a way as to create a "ball" of fire (called the combustion zone). Only 25% of the air is actually used for propulsion, the other 75% is used to "cool" the engine. So unburned air is placed between this combustion zone and the walls of the engine. In addition the turbine blades are somewhat hollow and air is forced through small holes to keep the blades cooled. This is a delicate process. If too little air is pumped, the blades will melt, if too much air or if the air is delivered with too high of a pressure, the jet of air coming out of those holes will be too far from the surface of the blade and once again, the blade will melt. Engines are a marvel of engineering. Thanks for the video.

This is a great question! In reality the jet engine will suck in far more oxygen then it needs. The fuel-air-ratio is very low, meaning that there is substantially more air than fuel entering the engine. This is also known as running 'lean'. All this results in plenty of oxygen left over for the afterburner!

3:24 “this jet of air pushes the plane forwards’. It’s actually not the air being expelled that pushes the jet forwards but the process of the hot (high pressure) air being replaced by cooler ambient air at low pressure. The air escaping a balloon experiences the same effect. The reason the air is heated is to generate a higher pressure as hot air is more compressed, or of a higher pressure than unheated air. A jet engine isn’t pulling air through as much as its heating air to generate a cushion of incoming, cooler, low pressure air. It’s the same concept as the propellor driven plane but the forces affect the inside of the exhaust rather than the inside of the propeller blades.

I think you overestimate how many aircraft use jet engines. The vast majority of GA aircraft are piston-propeller aircraft. There are more than 100,000 Cessnas, Pipers, and Beechcraft still flying around regularly, with models that are still in production. And new GA designs, like Diamond and Cirrus, use piston-propeller power, because they're much cheaper to build, maintain, and fuel.

Modern fighter jets use _low bypass_ turbofan engines, not the high bypass type used by passenger jets. High bypass turbofans are far more fuel efficient than the low bypass type but can't be used for supersonic flights. The cross-section area of a high bypass turbofan with sufficient thrust is also too large to fit inside the relatively small hull of a fighter.

When we put even more fuel into the engine (for the afterburner system), we are changing the thermodynamic cycle slightly.

No afterburner = fixed nozzle
