Abstract
The results of an experimental study of the possibility of burning separated and discharged to the Earth's surface are presented on the example of the design of elements of the head fairing of a launch vehicle. A new scheme of a honeycomb-free three-layer construction of combusted elements of the head fairing using a charge of high-energy material is proposed. Based on the formulated requirements for the characteristics of the charge and analysis of the results of thermodynamic calculations, the basic compositions of high-energy materials (HEMs) were selected. The energy and strength characteristics of the selected HEM compositions are experimentally determined, and the patterns of their combustion at subatmospheric pressure are determined. The results of laboratory tests of the combustion of elements of the structures under consideration with a VEM filler charge showed the possibility of partial utilization of spent parts of the launch vehicle.
