On developing method for determining materials properties and combustion system structural elements of launch vehicles separated parts

Abstract

Abstract The article considers a new class of problems, which studies the issues of burning the launch vehicle (LV) separating structures made from polymer composite material, including fillers and carbon fiber. As illustrated by the structure of the payload fairing (PF), which must undergo forced burning after the mission, four concepts for determining the materials properties are proposed. In conducting experiments in the wind tunnel with the implementation of the actual conditions of high-speed flow, the PF structural model is introduced in the consideration. The results of theoretical and experimental studies performed to determine the properties of the materials that make up the filler and carbon fiber are presented.
