So you added the drag equation and make it seem like everything's a lie. Alright, lets start: 3 compressors on the engines, they don't care about the altitude because the compressors will keep it running at an optimal O2 to fuel ratio. Max Speed is the maximum speed at cruising altitude w/o a combat load. Operational radius is calculated at cruising altitude and cruising speed, that's why a combat radius and extended radius are always gonna be different. You took the basic trick of adding a little bit of truth but then forgot to mention a lot of factors that we, aircraft enthusiasts, take into consideration. An A300 flying from LA to JFK will take the recommended amount of fuel + a couple thousand pounds as a buffer, why? Because at cruising altitude and a given thrust, it will give them the best fuel economy possible.
@@SuiLagadema Compressor gets power from the turbines, at altitude compression gas flow, air mass flow and exit velocity they all go down. To provide the same O2 Ratio at altitude the compressors have to work harder to compress the thin Air, The Corrected thrust is improved but not raw thrust. Again aerodynamics is very complicated and in this video we just tried to give a rough idea how the engine works. Will try to make a detailed video in the future. BTW thank you for the support🙏🙏🙏🙏
Any specs you look at online for any plane you might figure will be a little classified, you can just assume those numbers aren’t correct, in fact you could probably inflate them quite significantly. Like the top speed for Chinooks, f117’s, and b2’s being actually classified but google will give you an answer, a wrong answer though
So why is it the F-22 has like almost 20k more thrust than the F-15 but is .3 mach slower. I assume the mach 2.5 speed of the F-15 is with no weapons or tanks attached. But I would still think the F-22 is more streamlined than the F-15. Not sure what the weight difference is. But yeah Is it just the amount of air vs speed of air that makes the F-15 faster but lower thrust? I just assumed that the F-22 was probably faster than they led on.
Well first reason is obvious, the weight F-22 is about 8000kg/17600 lbs heavier than an F-15, and its relatively more difficult to produce lift cause of its 2-axis vector nature. Other is the engines, F119 Low bypass turbofans were designed for high specific thrust at low rpm while not sacrificing high end thrust, but still for the USAF longer engine life mattered more so compressors were optimised more for supercruise. Also the rectangular exhaust bleed a bit of thrust unlike f-15s round Exhausts, but are more stealthy. You know what I am gonna research more on this and make a video. BTW thank you for the support🙏🙏🙏 Means lot☺️
@@Liquidrocketwolves yeah i just never seen someone explain it. I’ve heard that the F-22 is optimized for super cruise. So that takes away from top end speed. But man 20,000lbs is a lot of thrust.
There are design limitations due to stealth characteristics that compromise flying efficiency. Greater weight, higher wing loading and increased wing area of Raptor limit speed. But the engines can produce enough thrust without afterburner to cruise at Mach 1.7 and the thrust can be vectored up or down for turn performance.

Just made a new account, got recommended this. I guess I am interested in planes now.😐🤷♀️🤷♀️

You just described teenage me.😅
