Abstract
The invention relates to an improved deformable downstream disc (56; 156; 256) to be fitted on the bottom of a container (15) for a missile (16) and including a stack of elastic blades (63) clamped between at least an upstream and a downstream thermal protection membrane and sealing membrane (70, 71, 72, 73), and maintained between an upstream bearing frame (61) and a downstream bearing frame (64), characterised in that the downstream bearing frame includes an inner edge (80) having an extension so as to provide the disc with an abutment means defining a position of maximum deformation of the elastic blades.
Claims9
A deformable disc (56;
- 156;
- 256) which is to be fitted to the bottom of a missile container (15) and is capable of opening under the thrust of the propulsion gases of a missile (16) contained in the container and of closing again after the missile has been ejected, the disc comprising a grid (62) and a stack of resilient plates (63;
- 163;
- 263) which are clamped between at least one heat protection membrane and a sealing membrane, upstream and downstream (70, 71, 72, 73), and held between an upstream bearing frame (61) and a downstream bearing frame (64), characterised in that the downstream bearing frame has an inside edge (80) which is extended in the downstream direction and is profiled so that it comprises a convex upstream portion (90) and a straight or concave downstream portion (91) capable of shaping a free end (96) of each resilient plate (63), so as to provide the disc with stop means defining a position of maximum deformation of the resilient plates, ensuring that the material constituting the plates (63;
- 163;
- 263) retains its mechanical resilience properties.
