FIELD: ecology.
SUBSTANCE: in the method the cleaning of containers of liquid-propellant rockets after start from fuel components is performed, in which fuel is unsymmetrical dimethyl hydrazine and the oxidiser is nitric tetroxide, by washing the container manifolds with neutralising solution. At that preliminary washing of filling manifold is carried out with water under pressure from a volume equal to the volume of the manifold, after which the fuel manifold is washed with an aqueous solution of potassium permanganate with a concentration of not less than 0.1%, and the oxidiser manifold - an aqueous solution of caustic soda with the concentration of not less than 0.025%, at that the safety of drainage and the container manifolds is controlled for subsequent disposal.
EFFECT: invention provides a high degree of cleaning of the enclosed volume of the piping from components of rocket fuel.
