Analysis of Parameters Affecting the Dynamic Stability of a Rocket Launcher
Prof. Ratko Šelmić, PhD Radomir Mijailović, PhD Vlado Đurković, PhD
This paper considers several different parameters of a rocket launcher (thrust level, rocket mass, launch ramp length, and others) which have the greatest effect on its dynamic stability. A relatively simple mechanical model, with both rigid and deformable elements, is formed for the purpose of stability analyses. The dynamic stability of the rocket launcher, as well as the launch ramp as its component subassembly, has been examined. The resulting analytical expressions have been verified by a numerical example for a real object. The actual results can be useful to engineers in the process of designing new or reconstructing the existing rocket systems, as well as to the technical support service responsible for issuing regulations regarding the handling this type of artillery armament.
Key words: dynamic stability, rocket launcher, deformation, thrust level, rocket mass.
