This video is more awesome than people may realize. This video captures the following visual information I have not seen in other videos. First, it shows clearly how the air flow volume is actually only a thin cylinder around the spinning fans. Most pepole don't realize that air hitting the engine does not go through the engine even close to the center. Second, it shows how this particular kind of engine has not one but two coaxial counter-rotating shafts. Three, it clearly shows the angle of the compressor blades (I mean the moving blades) and the stator blades (the fixed position blades along the outside). Fourth, the second and third features combined allow you to imagine how the air flows from the forward exterior fan, gets pushed through and will start spiralling, and the *spiral* flow from the front engine fan then meets the first row (part of first stage?) of compressor blades at a *low* angle of attack (the blades are efficiently moving through spiraling air like a wing). I always wondered how the blades were not acting like a wall pushing air. It's because the air coming at them is spiraling and not racing straight in. This reduces the angle of attack, so the compressor blades don't create turbulence (or stall). Then you can imagine (yes, you need to imagine) how the first row of blades starts reducing the spiral flow, so the next row of blades needs to be angled to face more of an axial than spiral flow. This continues through the compressor stage. The video does fail to mention there are two stages (or three? if you count the front blade?). From what I call the first stage, the air still has some spiral motion, and the second stage of blades then rotates in the opposite direction from the first, allowing the blades (like before) to meet the air with less angle of attack. This allows for reduced turbulence/stalling while allowing the blades to do more work. Again, the fans have less and less angle as you go from front to back. All while this is happening, look how very little space the air is moving through. It gets smaller! Now, an engine working at a steady speed always has a steady amount of air mass moving through it (lets say pounds per minute). Each slice of the engine has the same flow rate. Where I pointed out the cylinder gets smaller, the mass moving through has less space, so it must be more dense. That means it *must* be at higher pressure (unless you could magically cool it to reduce the pressure). So, you see the air must be flowing through at higher and higher pressure. Then, when it gets past the second stage (second set of fans), the flow is allowed to expand where it meets the fuel. NORMALLY, expanding air flow reduces the pressure. However, the fuel is ignited at the expansion point. The heat is just like an explosion - it prevents the pressure from dropping. So, you go from a narrow, high-pressure flow to an expanded area with similar pressure. Note - the pressure is NOT greater in the combustion chamber than right upflow. If it were, the flames would move forward. No, the pressure actually DROPS in the expanded flow in the combustion chamber but not much. However, although pressure keeps dropping from final compressor fans to combustion, the ENERGY/work put into the air dramatically increases due to the burning fuel that is preventing the pressure drop in the expanding flow volume. Then, this air is once again squeezed through a narrowing opening, speeding it up and meeting the exit stage of the turbine. (I don't know the terminology.) I may sound rambling, but my point is - I have not seen a video that allows you to see the moving parts this way. I am especially stunned I did not know (a) how narrow the air flow cylinder is and (b) that the engine has counter-rotating shafts, one poking through the other. Cool!

@@BrunoBoy3913 - I saw mine at Beale. I was with a small summer contingent of USAFA cadets that stayed there a couple of days. Operation CONUS was the name of the program I was in. Small groups of cadets were sent to tour various groups of three bases for two weeks. My group was Beale, McClellan, and Travis. (A few years later I ended up serving at Travis as a lieutenant in the Travis 22nd AF Ops center Weather Support Unit, plus doing flight line wx briefs and forecasting). I remember touring the Beale maintenance facilities and one airman animatedly expressing his passionate hate about how often his uniform got wet from all of the leaking fuel and hydraulics, plus all the laundering required! That was kind of funny. He and some others were not fond of the Marysville area. What did they want, New York City? That's life in the AF for most people. So, we got to see a daytime takeoff of a U2 and a takeoff of a Blackbird, plus a sit in the simulator - but it was off and a few things were covered up. The sim was cool and lame at the same time. Us cadets were a little bummed, as we had heard from others how they were given flights in F-15s or at least cool sim rides at their respective bases. We ended up riding in KC-135 that refueled a Blackbird. We each joined the boom operator for a bit. That was a special treat. How many people get to do that? I think the ride doubled up refueling F-16s as well, or maybe that was another tanker ride. It is still amazing (to anyone not in a coma) how superior the Blackbird was to anything else that ever flew high and fast.

The most efficient engine is one that spits out a stream of air at almost the same velocity of the external airstream. So if your plane flies at 560 mph, a high bypass engine will dump air out the back at just below the speed of sound.

if you put a tesla coil on the cone of a jet engine, would it create plasma as it was sucked into the engine for more thrust? also would it pull hydrogen out of the air that would com-bust as it went threw engine? since electricity is used to pull hydrogen out of water and there is moister in the air?
@epion660
5 жыл бұрын
That would not really be functional, and certainly not practical. The Tesla coil would be more trouble than it's worth, quite possibly screwing with all the other electrical systems on the craft, and shielding that would be too much work to make it feasible. It would not create a noticeable (if any) boost in performance. Many aircraft engines (both jet and piston) run better with colder air intake. And even flying through a cloud would not give a reasonable amount of hydrogen using such a method. Oh and final point, just having a random amount of hydrogen going into the engine will completely ruin fuel efficiency, because the air/fuel mix is perfectly balanced for maximum power with minimal fuel. Adding varying amounts of hydrogen will throw off the fuel/oxygen mixture from the air, negating any benefit.
