METHOD OF COMBUSTION OF SOLID PROPELLANT Russian patent published in 2006 - IPC F02K9/24 

FIELD: solid-propellant rocket engines.

SUBSTANCE: invention relates to technology of destruction of large-size solid-propellant rocket engines. Proposed method of combustion of solid-propellant rocket engine installed in horizontal position on stand comes to combustion of solid propellant and cleaning of combustion products with subsequent discharge of remaining gases into atmosphere. Tunnel is used to clean combustion products whose capacity is not less that volume of combustion products formed at combustion. Prior to starting combustion, flow through conditions are set in tunnel by pumping through air with mass flow rate corresponding to maximum mass flow rate of combustion products formed at combustion. In process of combustion, to provide gradual filling of tunnel by combustion products, mass flow rate of air through inlet of tunnel is regulated to comply with mass flow rate characteristic of combustion products. At moment of completion of combustion, pumping of air through tunnel is stopped, and combustion products are held in tunnel till completion of off-standard processes. Then air is blown through tunnel at conditions providing dilution and discharge of gases at tolerable concentration into atmosphere.

EFFECT: provision of high ecological safety at combustion of solid propellant owing to effective cleaning of combustion products.
