Appl. No.:

10/955682

Inventors:

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

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.

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.
