| Abstract: | A concept of supersonic velocity craft in near space was presented,which flies at a height of over 70 kilometers.This craft conquered the atmosphere resistance with the thrust provided by the rocket engine and enhanced the gravity acceleration constant with the pneumatic subtractive lift to reach the onslaught flight at a velocity above the escape speed.This mode of flight possessed of the characteristics of high speed and long voyage.Some dynamics issues were discussed,such as pneumatic parameters selectio... |
