Abstract

Abstract: The article considers fundamental engineering problem of designing the payload fairing (PLF) for a launch vehicle (LV) made from polymer composite material (PCM) with high temperature resistance and minimum mass, with the PLF being incinerated after separation from the launch vehicle on the atmospheric section of the descent path. The energetic material (EM) is introduced into the PCM, which provides heating of the PCM structure to the ignition temperature and subsequent PLF combustion under the conditions of the incoming air flow. A comparative analysis of the problems arising at different life cycle stages in creating and operating traditional (PLFT ) and incinerated (PLFI ) payload fairings is carried out. Example options for energetic materials and possible designs of the individual PLFI elements are given.
