Abstract Propulsion system operation is known to affect the aerodynamic characteristics of rockets. Specifically, net axial force acting on a rocket in flight cannot be precisely obtained by combining static thrust with drag values computed for an inactive motor. One main reasons this influence motor pressure at base rocket. The aim paper investigate effect parameters Grot sounding developed St...

As the research on hybrid rocket motors advances, more accurate tools are needed to estimate performance of system by determining its fundamental parameters. One them is certainly regression rate solid fuel. Unfortunately, it depends many complex physical phenomena and interactions which vary with time, space scale, making task predicting evolution very difficult. To address this issue, Computa...

T study demonstrates the advantages of using a real coded genetic algorithm (GA) for aerospace engineering design applications. The GA developed for this study runs steady state, meaning that after every function evaluation the worst performer is determined and that worst performer is then thrown out and replaced by a new member that has been evaluated. The new member is produced by mating two ...
