Analysis Of Dynamics Characteristic For Hypersonic Vehicle

Hypersonic aircraft can attack the goal nearly one thousand kilometers far during the time under 10 minutes relying on high speed (cruise at 6-10 Mach). This kind of aircraft will not only improve the sudden and validity of the weapon, but also make the time of fighting greatly short, accelerate the war process. Because of the high speed of the hypersonic aircraft, the response time to leave for the system of defense is very short, effective area of interception system is very little, interception probability will drop at a large degree, even enable intercepting the weapon and lose the chance of launching. The value of military affairs is very important.Hypersonic key technologies that aircraft is studied involve integrated scramjet design, the research of impetus system. This thesis analyses overall key technology and dynamic characteristic, the main content includes:1, comparison and analysis of the characteristic to several kinds of typical hypersonic aerodynamic configuration, include the wing body, ride wave body, lift body, and analysis aerodynamic configuration and key technology of the scramjet and the control scheme of the hypersonic aircraft finally. It is hypersonic developing direction that ride wave body aerodynamic configuration, dual-mode scramjet and BTT(bank to turn) control scheme.2, According to the characteristic of the hypersonic aircraft, the task of designing the hypersonic aircraft include initial phase, cruise phase and end attack phase. According to giving the initial condition defined, have calculated the ideal trajectory of the whole flight phase of the aircraft, and carry on simulation analysis.3, The longitudinal dynamic characteristic and lateral dynamic characteristic of hypersonic aircraft are analyzed because equation of motion is linearization by small disturbance theory, including quiet stability, freedom disturbance movement mode and characteristic of handling, analyze and prove weather aerodynamic rudder and STT (side to turn) control method could meet hypersonic request of mobility especially.
