METHOD OF DESTRUCTION OF PARTS OF WASTE SPACECRAFTS AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC B64G99/00 B64G1/66 C06B33/00 

FIELD: aviation.

SUBSTANCE: in order to destroy the parts of waste spacecraft by perforating the high-heat structural material of the spacecraft components when it falls in dense atmosphere, a pyrotechnic composition of thermite type, based on aluminium and metal oxide, capable of self-ignition at a temperature of 900-1000°C and with an exothermic effect of at least 4200 kJ/kg, is applied to the surface of the spacecraft parts. The pyrotechnic composition of thermite type is filled in a cylindrical nozzle made of titanium alloy, which is fixed on the surface of spacecraft parts. To ensure the compression of the pyrotechnic composition to the surface of the material, an elastic heat-insulating liner is installed inside the cylindrical nozzle.

EFFECT: method and device provide high safety, stability and reliability and allow perforating the high-heat parts of waste spacecrafts at the stage of their uncontrolled descent in dense atmosphere.
