The subject of the present invention is a device () for propelling a liquid (L) comprising a reservoir () equipped with a mobile separation member () and a pyrotechnic gas generator (), which is arranged inside said reservoir (), equipped with nozzles (). Characteristically, said nozzles () of said gas generator () are arranged radially on the wall(s) of said body () and said gas generator (), arranged in such a way that its axis corresponds to the line of travel of said mobile separation member (), is equipped with a deflector () to deflect said generated combustion gases (G) along said line of travel of said mobile separation member ().

The invention relates to a thermal erosion test device for testing thermal protection materials for use in a solid propellant thruster. The device comprises a support for holding a plate made of the thermal protection material for testing so that its faces a face of a block of solid propellant, the space between the plate and the face of the propellant block defining a combustion chamber of substantially rectangular shape, said chamber extending along said plate and opening out into a nozzle.
