Launch Dynamics Analysis Of Rocket And Missile With The Same Moving Launch Device

The rocket and missile with the same launch device researched in this paper is a new long-range missile-rocket integration weapon system which launchs missile and rocket from the same launch platform. It has some characteristics in rapid firing rate, maneuvering capability, larger firepower envelop, longer firing range, point fire and area fire and convenient field operations. The rocket and missile with the same launch device has been paid great and wide attention by every powerful country in military.A rocket and missile with the same launch device is taken as research subject, a launch dynamics model with rigid-flexible-body of rocket and missile with the same launch device is established. Based on discrete time transfer matrix method of multibody system, the transfer matrices of every element and the overall transfer matrix of system of rocket and missile with the same moving launch device are deduced. The forces acting on the rocket and rocket artillery are analyzed when the rocket and missile with the same launch device fires in moving. The effect of movement of rocket in bore due to the moving vehicle is considered and the launch dynamics equations of rocket are considered. The simulation program of dynamics of rocket and missile with the same moving launch device is developed. The dynamics response, movement of rocket in bore, initial disturbance of rocket and firing precision of rocket and missile with the same moving launch device are obtained. Those results offer the necessary base for researching firing accuracy of rocket and missile with the same launch device.
