Environmental Adaptability Study of H2O2 Engine Applied in the Launch Test of Near Space Spherical Spacecraft
Ground testing was conducted on an engine test system using hydrogen peroxide(H2O2)as the propellant for spherical launch vehicles in the special environment of near space,and environmental adaptability research was also carried out.The results indicate that the single component engine system scheme using H2O2 as the propellant has good safety and environmental adaptability,is easy to use,and can be used as a power propellant choice for future spherical launch vehicles.In the testing plan,PTC heating elements,combined with temperature control switches and insulation materials,were used to maintain the temperature of the engine fluid storage tank and nozzle wall between 38～42℃,meeting the requirements of the real flight environment of the aircraft.The engine performance was good after testing.
