ABSTRACT:
The present invention relates to thrusting apparatus such as may be used for guiding projectiles such as gun launched projectiles and hypervelocity missiles.
Missile or projectile control may be achieved by producing thrust at right angles to the missile or projectile axis in a single radial plane thereof. If the pulses are provided by separate axial flow motors which are positioned with their axes normal to the projectile axis, space limitations may undesirably limit the number of pulses in the same plane.
The firing of a number of gas generating devices into common plenum requires a specific orientation of the plenum opening to achieve the desired results. In other words, the firing must occur at a specific time when the plenum opening is at a specific point during spinning of the projectile
Fluidic devices which direct gas flow into laminated structures require a large number of electronic components and stages and may allow gas leaks in undesired directions. A large amount of space as well as weight, which are at a premium on missiles and other projectiles, may as a result be undesirably required.
It is accordingly an object of the present invention to provide a thrusting apparatus wherein the pulses are all in the same radial plane or in a pair of closely spaced radial planes.
It is another object of the present invention to provide such a thrusting apparatus which occupies a minimum amount of space and has a minimum weight.
It is a further object of the present invention to provide such a thrusting apparatus which is rugged yet reliable.
The above and other objects as well as features and advantages of this invention will be apparent in the following detailed description of the preferred embodiments thereof which is to be read in connection with the accompanying drawings.
