    1:28 When Running Properly, fuel in an aircraft cylinder engine should not explode; An explosion or detonation is a malfunction and is very damaging to the engine.
    1:57 - 2:25 While you are correct about the cooling and aerodynamic aspects there is also a huge aspect of efficiency, ease of manufacturing, maintenance, "ideal conditions", power to weight, fuel and metallurgy technologies and even vibration certainly come into play.
    2:29 Maximum speed is not the sole benefit of a different engine technology.
    2:32 Rocket engines are actually more efficient in some ways than turbojet engines under the premise of speed per fuel and weight. It is more propulsively efficient because of its light weight and small size for the weight with a propulsive efficiency of about 70%.
    2:47 Jet engines is a poor choice of words because a rocket engine is a kind of jet engine. You seem to have conflated it with turbine engine. A Jet engine is any kind of reaction engine, that discharges a fast moving stream of mass to generate thrust. A Rocket engine or even a Pump-jet, as may be found as propulsion on a boat are both jet engines. The aeolipile dating to around 150 BC was also a jet engine. A Turbine engine is merely one such kind of jet engine.
    4:01 A Ramjet is not a turbine engine as it does not make use of a turbine for compression
    4:32 Modern Fighter Jets do not use Turbojets, they use Low Bypass Turbofans which are the previously mentioned turbofans with less bypass. Its also not very powerful.
    6:02 This is not accurate. A ramjet is only like a rocket in the sense that it is a Jet engine. Unlike a rocket a ramjet is airbreathing and uses relative wind to the aircraft to slow and compress the air, then, it adds fuel to and ignites. It cannot function like a rocket and does not have oxidizer. Ramjets also begin producing meaningful thrust around .5 Mach at sea level (384mph)
    Also this misses a LOT of huge elements like, maintenance, economic factors (like fuel costs), distance, the mission requirement, aerodynamic drag, the limits on each kind of propulsion, other efficiencies, temperatures, density altitude, manned aviation concerns like pressurization, heat and time for the pilot, also you did not mention Lift, Bernoulli's, Otto cycle (Piston) or Brayton Cycle (Turbines) and perhaps greatest of all, The inevitable tradeoffs that result from anything that expends energy.

      one note: explosion is not same as detonation, first is slow, second is fast because fuel falls apart on h an c , and h burns fast and that is detonation, in piston engine is single burn event in jet engine it burns constantly or constant explosion but not detonation, difference between igniting cigarete lighter and spark plug starts burn is cylinder is closed space, cigarete lighter is in open space

      "Also this misses a LOT of huge elements like, maintenance, economic factors.."
      Question: How is the last point relevant to the topic of discussion aka How do they work.

    • @I86282
      @I86282 2 года назад +7

      3:30. #1. A Jet Engine is not at all the same as a Rocket Engine. Like seriously what the hell.
      Yes they both produce thrust through Newton's 3rd Law. But that is the end of their similarities. From a engineering standpoint.
      A Rocket does it by accelerating Mass. And a Jet Engine does it by pulling Mass through it.
      And therefore are very different.!
      #2. That's Not called the "Exhaust". It's called the "Power Turbine" section. And it spins the Intake and Compressor Blades. It's literally the whole function of a Jet Engine. But yeah you wouldn't want to get that part right. In a video about Aircraft Propulsion.
      And then after the Power Turbine Section. Comes the Exhaust section. Which in most aircraft. The exhaust cavity volume is adjustable. For higher gas compression.
      No you didn't particularly need to know that information. But if you are making a video describing it's functionality. You might want to have that in there.
      But an otherwise interesting video.

    During the Second World War there was a test aircraft in Switzerland which was powered by a wood gasifier.
    It was called AC-4 (HB-USI) and required 34kg of wood per flight hour. 😀
    The aircraft still exists today and can be viewed in the Flab & Fliegermuseum in Dübendorf.

    A very interesting type of piston engine used in aircraft for some time was the rotary engine, where the whole engine rotates and the crankshaft remains stationary. The Wankel engine has also been used in aircraft as a proof of concept.
    The Pulse jet concept was also used in planes although again not very successfully.

      In Archimedes' formulation, the effort arm was equal to the distance from the fulcrum to the applied point of effort and the load arm was equal to the distance from the fulcrum to the center of the load weight. Thus established, the effort multiplied by the length of the effort arm equals the load multiplied by the length of the load arm, which means that the longer the end of the effort, the less force is required to lift the load. Simply put, if you are attempting to lift a particularly heavy stone, it is best to use a longer crowbar and place the fulcrum as close to the stone or load as possible. It sounds the gravity and the rising of the entire universe or the development of cloud modules and shapes and they move in remote virtual paths (without stretches or infrastructures) independently of ionic electricity. Step-by-step logic and gravity need to be applied in mechanical problem solving and equipment design. In doing so, he created the machines that transformed the world and his impact remains powerful today.

      @@Joyplanes Which engines forgot to mention: gyrodine. And, of course, the nuclear air engine. In the future, nuclear batteries, RTGS, will allow for a flight without landing for a year or longer, for unmanned vehicles. Compact atomic reactors based on molybdenum crystals are currently being developed in Russia. I've seen photos, it's the size of a household refrigerator. But such nuclear reactors will most likely be used for an atomic planetship, which is currently being designed by the Khrunichev Bureau. Nuclear reactors have already been successfully put on a hypersonic rocket, which will allow the rocket to make a suborbital flight and reach anywhere on the planet, without a chance for air defense. Such things.🙂

    Concerning the SR-71, at speeds above Mach 2.5, the spikes on the front of engine intake retract reducing airflow into the compressor and diverting it around to the exhaust where the afterburner ignites the fuel with it. I believe the process is gradual to prevent a flameout. At maximum speed the engines are operating as ramjets.

    I wanted to shout out the propfan: an experimental engine that could be described as a cross between a turbo fan and a turbo prop. It looked like a jet engine with propellers attached to the back. They ran a few experiments, but the advantages never emerged, and it was extremely loud.

    • @imano8265
      @imano8265 2 года назад +1

      I agree totally. There were several reasons (not only good ones) that this technology didn´t come to life up to this day. It was developped in the late 80s and early 90s much in order to save fuel and was successfully testet. I think they turned it down because it would have remind the people to much of a propeller...anyway in the mean time the so called "jet-engine" became bigger and bigger because of the augmented bypass and I don´t know how long this can go further and further by calling the result a jet-engine.

    • @calvinnickel9995
      @calvinnickel9995 Год назад +1

      The prop fan has a lot of disadvantages because the airflow over the blades must be supersonic and that creates a lot of noise as well as losses that can’t be recaptured like a ducted fan.

    One note about the turbojet / turbofan. Turbojets on mil aircraft were phased out in the 50s / 60s. All modern fighters use turbofan engines, just with different bypass ratios than the ones used on big planes.

    One type that is used or was used is the pulsejet engines. They may still be used on model planes but they are very loud and the fuel consumption is very high. They powered the German V1's. Also, in model aircraft, there are ducted fan powered by internal combustion engines or electric motors.

      I can imagine they start with an electric motor to start intake air, then a fuel rich initial combustion then as it speeds up gets more air and then the optimal fuel-air mixture combustion.
