The Use of Pyrotechnic Composition for Dispersing Fairings During Atmospheric Re-entry

Considered alternative technical solutions for solving the allocation of the impact area for the leaf of the payload fairing of launch vehicles, including technology-based aerodynamic manoeuvres (different types of parachute systems) and the burning of the segment of the payload fairing with the use of pyrotechnic composition (PC). Conducted formulation studies of the thermal stress and strength in the process of its motion during the atmospheric phase of the trajectory of the descent in summing up additional heat from the initiation of PC. Adduced the mathematical methods and models for solving the formulated problem. Proposals for experimental facilities based on University research and education laboratory.
