F/A-22 Raptor
Fast (super-cruise*) and stealthy, and integrated avionics are cool, but what's really impressive is the F/A-22s low speed stability and maneuverability. In the late 40s and to early 60s aeronautical engineers were going nuts on how to shape intakes to handle both subsonic and super-sonic air flows, without stagnation or compressor stalls. Supersonic in itself was a big challenge because you ha
More..d to use shock waves to slow the intake air mass to sub-sonic before it hit the compressor blades, or they would stall. The engineers figured it out, but the solution was keeping a lot of air going in the front end to make sure the all hot air kept going out the back end. As you watch this Mach 2 airplane suspend motionless in air and do tail slides, be aware of the truly amazing performance of the engines and intakes. Less..
