摘要

FIELD: rocketry. ^ SUBSTANCE: invention relates to destruction and recycling of solid-propellant rocket engines by combustion of charges of solid-propellant. Proposed method of recycling by combustion on stand includes fastening of solid-propellant rocket engine by nozzle part inwards elongated mixing chamber. Then ignition is done and delivery of oxidizing fluid into mixing chamber is provided in process of burning of solid propellant for its afterburning. Oxidizing fluid is delivered uniformly over perimeter of mixing chamber in zone of location of nozzle part of solid-propellant rocket engine. Chilling of main lines delivering cryogenic oxidizing fluid is carried out before ignition of solid-propellant rocket engine. Oxidizing fluid is essentially mixture of liquid oxygen and liquid nitrogen. Oxidizing fluid is delivered from stationary or portable contains along pipelines with equal hydraulic and thermal resistances to spraying nozzle providing particles of 10-100 mcm. Nozzles are uniformly spaced over perimeter of mixing chamber. ^ EFFECT: reduced capital outlays for construction on stand installation, reduced time taken for mounting and adjusting of objects of infrastructure, simplified design of stand and reduced cost of its operation. ^ 6 cl, 4 dwg
