Filed:

Sep 8, 2006

Appl. No.:

11/530194

Inventors:

Joseph P. Morris - Bothell WA, US
Douglas L. Smith - Bellevue WA, US

International Classification:

F42B 10/02
F41G 7/00
F42B 10/00

US Classification:

244 323, 244 31, 244 315, 102501

Abstract:

Trajectory is controlled by a control system having fins that de-spin a section of the control system relative to a projectile or missile. The control system also includes aero-surfaces that produce a lift when brought to rotation speed of about 0 Hz relative to a reference frame and a brake that couples the guidance package to the rotational inertia of the projectile or missile. In one example, no electric motor is used in the trajectory control system, saving weight and increasing reliability.

Assignee:

General Dynamic Ordnance and Tactical Systems, Inc. - St. Petersburg FL

International Classification:

F42B 10/02
F41G 7/00
F42B 10/00

US Classification:

102473, 244 323, 244 31

Abstract:

The invention relates generally to a roll damping apparatus for a spinning projectile having a first section and a second section rotatably attached about a roll axis. The roll damping apparatus comprises a first portion attached to the front section, and a second portion attached to the rear section. The first portion is adapted to cause a braking frictional force to act on the second portion, the braking force being effective to control the spin rate of the front section relative to the rear section. The invention further relates to a spinning projectile having a roll damping apparatus.

Appl. No.:

12/617634

Inventors:

Joseph P. Morris - Bothell WA, US
Douglas L. Smith - Bellevue WA, US

Assignee:

General Dynamics Ordnance and Tactical Systems, Inc. - St. Petersburg FL

International Classification:

F42B 15/01
F42B 10/26

US Classification:

244 321

Abstract:

The invention is a projectile, device and system having a roll control device which may be fixed or deployable, for providing torque counter to the spin of the projectile and providing drag on the projectile. The roll control device includes a guidance collar rotatably attached to the projectile located near a front end of the projectile wherein the guidance collar includes one or more guidance collar aero-surfaces shaped to provide torque counter to the spin on the projectile. The guidance collar aero-surfaces may be controlled by a brake and guidance electronics on the projectile. The invention also includes a body collar fixedly attached to the projectile aft of the guidance collar, wherein the body collar includes one or more body collar aero-surfaces and fixed or deployable drag devices. Another embodiment use only a guidance collar aero-surfaces to orient a fixed drag device relative to an Earth inertial reference frame to create asymmetrical drag on the projectile and thereby altering its trajectory.

International Classification:

F02C 330
F02K 942

US Classification:

602001

Abstract:

There is provided a system for the delivery of a gaseous product to a reaction chamber. The system includes a fuel tank containing a hypergolic liquid displaced from the fuel tank by a pressurized gas whose flow is controlled by a thruster control valve and directed to a gas generator. Pressurant gas entrained in the hypergolic liquid is not decomposed in the gas generator and causes pressure oscillations. The pressure oscillations are minimized by reducing the diameter of the gas bubbles or by disposing a gas fluid resistor between the gas generator and the reaction chamber.

Assignee:

General Dynamics Ordnance and Tactical Systems, Inc. - St. Petersburg FL

International Classification:

F41G 7/22
G01S 19/13

Abstract:

An apparatus and system for controlling the trajectory of a projectile having two rotationally decoupled sections, wherein the first section is rotationally decoupled from the second section. The first section of the projectile contains a navigation system. The first section also contains an actuator by which aero-control surfaces on the second section are actuated. The second section may have external aero-spin surfaces which provide a torque counter to the rotation of the base projectile. The apparatus and system also includes embodiments having applications for nose sections of projectiles.
