Actuators for gun-fired projectiles and mortars

a technology of actuators and projectiles, which is applied in the direction of machines/engines, explosions, lighting and heating apparatus, etc., can solve the problems of difficult or impractical implementation of occupying a considerable amount of weaponry internal volume, and their application to gun-fired projectiles and mortars will be very limited, so as to achieve high efficiency and cost-effectiveness, the effect of simple design

Abstract

An actuator stack is provided and having two or more individual actuators stacked in a longitudinal direction. Each of the two or more actuators having a solid detonation charge; a primer for igniting the detonation charge; and detonation wiring for powering the primer; and wherein at least one of the two or more individual actuators comprise an accelerating nozzle having at least a convergent section terminating at a throat.

Description

CROSS-REFERENCE TO RELATED APPLICATION

[0001] This application is a continuation application of U.S. application Ser. No. 11 / 517,196 filed on Sep. 7, 2006 which claims benefit to U.S. Provisional Application Ser. No. 60 / 714,806 filed Sep. 7, 2005, the entire contents of each of which is incorporated herein by reference.BACKGROUND OF THE INVENTION

[0002] 1. Field of the Invention

[0003] The present invention relates generally to actuators, and more particularly to actuators for gun-fired projectiles and mortars.

[0004] 2. Prior Art

[0005] Since the introduction of 155 mm guided artillery projectiles in the 1980's, numerous methods and devices have been developed for the guidance and control of subsonic and supersonic gun launched projectiles. The majority of these devices have been developed based on missile and aircraft technologies, which are in many cases difficult or impractical to implement on gun-fired projectiles and mortars. This is particularly true in the case of actuation devices, w...

Embodiment Construction

[0057]Although the present invention is applicable to numerous types of actuators, it is particularly useful in the environment of actuators for gun-fired projectiles and mortars. Therefore, without limiting the applicability of the present invention to actuators for gun-fired projectiles and mortars, it will be described in such environment.

[0058]The disclosed actuators and method of their manufacture and integration into the structure of projectiles will now described in detail with regard to the Figures. It is shown that the disclosed actuators would provide very cost effective and have high actuation authority and dynamic response characteristics, while occupying very small useful projectile volume and requiring very low electrical power. It is also shown that the disclosed actuators can be capable of being readily scaled to the desired application. The disclosed actuator concepts could be built as modular units and could form the basis for developing a common actuator solution ...
