HYPERPLANE(INTRODUCTION)

Hyperplanes are planes flying at hypersonic speeds ( hypersonic speed is speed above Mach-5 ).Mach no is the ratio of speed of the object to the speed of the sound.The speed of the sound is about 340 to 350m/s.

Now we have planes flying at supersonic speeds.The fastest manned supersonic planes are SR-71 (USA)and MIG-25(RUSSIA).Previously the record for the fastest flight was set by X-15 (NASA).This plane flew at Mach-6.5.Other planes were XB-70 Valkyrie (USA) {This is the largest experimental aircraft ever built}.Soviet's made a similar type of plane called SU-T4 (This looked similar to XB-70).The supersonic commercial transport planes were Concord of France which is now grounded.TU-144 is the supersonic transport plane of Russia, which was not operationalized due to high fuel consumption , and high noise.

I will give more about history of hyperplanes
