Abstract
The invention concerns a device designed to modify the trajectory of a projectile by pyrotechnical thrusters, formed by several solid propellant thrusters arranged transversally on a cylindrical support. The combustion chambers, instead of having a cylindrical shape, are parallelepiped shaped. They contain propellant loads which are gone through by a rod connecting a streamlined to the support. The streamlined and the support are cut up to realize nozzles which allow the ejection of gas, the gas coming from the combustion of the propellant load. Thus for a given thickness (e) of the support, a greater loading volume is obtained than that which would be obtained with standard, cylinder-shaped thrusters.
Claims10
A device designed to modify the trajectory of a projectile by pyrotechnical thrusters, formed by several spaced thrusters, each of said thrusters containing a solid propellant load for forming combustion jets to give guidance thrusts that ensure that modification of the projectile trajectory, said thrusters being circumferentially arranged on a support shaped like a cylinder and centered with respect to a central axis of the projectile;
- wherein each of the thrusters positioned in a housing comprises a case with an interior surface, at least one face of which has a rectangular surface, said case containing a propellant load and an extruded nozzle center body connected to a rod going through the propellant load and fixed to the support, said extruded nozzle center body being spaced from said interior surface of said case for forming at least one nozzle enabling an orientation of a thrust.
