Embodiment Construction

[0018]A detonation thrust-producing device includes an explosive located in a recess in an external surface of a body. Detonation of the explosive expels material out of the recess, providing thrust to the body in an opposite direction. A mass, such as a metal disk, may be placed blocking or covering the external opening, such as in the recess between the explosive and the external opening. The body may be a part of a vehicle, such as an airborne projectile. The thrust-producing device may include multiple detonation motors arrayed around the body, capable of being individually or multiply detonated to provide thrust to the body in different amounts and / or in different directions. Such thrust-producing devices may be used for attitude adjustment, steering, or other control of the flight of the projectile or other air vehicle. The detonation thrust-producing devices have the advantage of a faster-response time than propellant-based devices, and do not need the nozzles that are used w...

Abstract

A detonation thrust-producing device includes an explosive located in a recess in an external surface of a body. Detonation of the explosive expels material out of the recess, providing thrust to the body in an opposite direction. A mass, such as a metal disk, may be placed blocking or covering the external opening. The body may be a part of a vehicle, such as an airborne projectile. The thrust-producing device may include multiple detonation motors arrayed around the body, capable of being individually or multiply detonated. Such thrust-producing devices may be used for attitude adjustment, steering, or other control of the flight of the projectile or other air vehicle. The detonation thrust-producing devices have the advantage of a faster-response time than propellant-based devices, and do not need the nozzles that are used with many propellant-based devices.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The invention is in the field of thrust-producing devices.[0003]2. Description of the Related Art[0004]Many sorts of devices are used for producing thrust for a variety of purposes. Traditional rocket motors use sustained combustion of solid or liquid propellants in combination with a supersonic nozzle to accelerate the exhaust products to high velocities, creating a reaction force. However such rocket motors are not suitable for providing reaction forces over very short timeframes.SUMMARY OF THE INVENTION[0005]A thrust-producing device uses one or more detonation motors with explosives, to generate thrust over very short timeframes.[0006]According to an aspect of the invention, a thrust-providing device includes: a body; and a detonation motor. The detonation motor includes an explosive in a recess in an external surface of the body. Detonation of the explosive provides thrust to the body opposite to the direction that...
