SR-71 "Blackbird" is the fastest known aircraft in the world. Making ultra-fast aircraft is not easy, because the heat in the atmospheric fly is very high, and that's why that very fast aircraft must rise above the tight layers of the atmosphere. The friction is the very bad problem, and that's why those aircraft must equip with the carbon fiber core, what would stand the extreme heat and pressure without melting. But the raise above the tight layers of the air would cause the problems because the jet motors cannot get enough air, and that's why the power of those machines would decrease.


One solution would pump the oxygen to the turbines from the liquid oxygen tanks, but that would cause decreasing the payload of that aircraft. And also oxygen tanks would decrease the flight time. So there must create the solution, what allows the motor to get tight air in the inlet, and the best way to act would be to design the aircraft that way, that the pressure wave, what would come from the nose of the aircraft would hit straight to the air inlet of the motor.


That would bring the tight air to the motor, and increase the altitude for all motors from turbojets and ramjets to flap ramjets and scramjets. The high speed would also increase the mass of incoming air to the motors. And that's why SR-71 got higher altitude than the U-2 spy plane. The SR-71 was withdrawn from the duty because of USAF afraid that the secret technology, what was used in that plane would go to the hands of Russians. But legend remains, and maybe the successor of the SR-71 is operational in somewhere inside the top-secret world of military intelligence.
