Experimental Simulation System of Transient Aerodynamic Heating for High-speed Flight Vehicle

In order to get parameters of the high temperature mechanical characteristic of different portions of the high speed flying body surface such as thermal stress,thermal strain and structural expansion etc,it is necessary to establish the experimental simulation system of the transient aerodynamic heating for high speed flight vehicle.The characteristics of transient heating control process of aerodynamic simulation experiments are complicated change,high non linearity,transient and strong coupling.Based on the fuzzy cintrol method,a transient aerodynamic heating simulation control system for missiles is completed.The quick and accurate dynamic control of aerodynamic simulation heating process according to the transient and continuous change of heat flow or temperature on the surface of the high speed flight vehicle can be completed by using this control system.
