Small-Size Rocket Impulse-Reaction Launch Dynamics
The method of analyzing the small-size rocket liftoff is presented. Under consideration is a system that consists of a rocket with an operating rocket engine, a launch tube, and an operating gas generator mounted in the tube under the rocket. The liftoff parameters including the rocket motion velocity inside the tube and the loads applied are calculated. The calculated and experimental data were compared and their adequate agreement is presented with respect both dynamics of rocket impulse-reaction liftoff from the launch tube and the launch velocity.
