Sensitivity analyzing of rocket ballistic parameters based on sensitivity function theory

In the flight of cannonball and rocket, due to various random factors the ballistic dynamic parameters in the flight dynamics model will occur randomly. Based on sensitivity function theory of control system and taking the angle movement into account, the algorithm of the sensitivity of the ballistic parameters for the aerodynamic parameters is brought out. In the same time, the degree of aerodynamic parameters impacting on ballistic parameters is analyzed. And a simulation example is also demonstrated. Thus more precise ballistic parameters of cannonball and rocket can be gotten with the aim of revising dynamics model and increasing firing accuracy of the cannonball and rocket.
