АННОТАЦИЯ

The design and results of a numerical analysis of the flight of the two-stage modulargeophysical rocket Zengzhang-1 are presented. The flight dynamics analysis of therocket (length 1795 mm, diameter 131 mm, mass 8797 g) for a given thrust profile of theL2200G rocket engine yielded estimated maximum parameters: flight altitude 3078 m,velocity 493 m/s (Mach 1.46), and acceleration 377 m/s². The rocket’s layout and use offins ensure a positive static margin and its controllability during both the powered ascentand ballistic flight phases. Simulation of the rocket’s angular motion demonstrated thatthe flight occurs vertically, with minimal aerodynamic drag throughout the entire flightphase up to separation.
