Patent number: 5183960Abstract: A rocket glider stabilization system wherein a releasable, granular, counterweight, or ballast material is provided in the forward end of a model rocket aircraft to offset the weight of a tail mounted rocket motor assembly. The counterweight ballast material is releasably maintained in a counterweight bay formed at the opposite end of the model glider fuselage from the rocket motor. A rocket body tube connects the rocket motor with the counterweight bay and, when the ejection charge of the rocket motor is ignited, the ejection charge pressure ruptures or opens a retaining structure to release the ballast and maintain the desired center of gravity for glide flight of the rocket back to the ground. At least one adjustable or fixed trim tab is employed on at least one of the flight surfaces to induce the desired glide path return for the model aircraft.Type: GrantFiled: June 27, 1991Date of Patent: February 2, 1993Inventor: James D.

Patent number: 5044281Abstract: A flare (1) for submarine use. The flare (1) is caused to be deployed from a submarine location where it will rise to the surface of the water because of its buoyant casing. A hydrostatic valve means (147) is provided within the casing and it opens when the flare is at or near the surface of the water to render said flare ready to project a flare composition (5) into the air. The hydrostatic valve means (147) is held inoperative by a latch mechanism (51) which is tripped as the flare is deployed from a firing tube at the submarine location. The flare composition (5) cannot be projected into the air until the flare (1) is within a range of vertical attitude determined by inclination means (13). The flare composition (5) cannot be projected into the air until the nose is above water. The flare (1) thus has a sensor (23) at its forward nose to determine that the nose is above the water.Type: GrantFiled: February 21, 1989Date of Patent: September 3, 1991Assignee: The Commonwealth of AustraliaInventors: Peter Ramsay, Brian W.

Patent number: 4750425Abstract: It is important with a sabot projectile to reliably fasten the projectile core or body in the sabot tail. This should be achieved without the need for circumferential grooves in the projectile core or body for fastening such projectile core or body in the sabot tail. Furthermore, the projectile core or body should be fastened in the sabot tail without the aid of the sabot jacket. This is achieved in that an attachment or fastening sleeve of the sabot tail extends to the substantially conical-shaped tip of the projectile core or body and bears against this substantially conical-shaped tip in order to prevent the projectile core or body from falling out of the sabot tail.Type: GrantFiled: March 16, 1987Date of Patent: June 14, 1988Assignee: Werkzeugmaschinenfabrik Oerlikon-Buhrle AGInventors: Hanspeter Sigg, Harald Katzmann

Patent number: 4729319Abstract: The controlled explosion projectile ejection system utilizes a source of combustible gas through a controllable input valve into a combustion chamber. Inside the combustion chamber is a sparking means. After the chamber is loaded or filled with gas, a spark control signal is applied to the sparking means and the gas ignites. At the output of the chamber is disposed a controllable output valve. In a simple embodiment, the output valve is simply a valve head biased against the output port of the chamber thereby inhibiting any gas flow from the chamber unless the pressure in the chamber exceeds the biasing force against the valve head. After ignition, the gas expands and the resulting pressure is much greater than the biasing force on the output valve head and the valve opens. Downstream of the output valve is a barrel with the projectile loaded therein. The expanding gas passes through the output valve and ejects the projectile from the barrel.Type: GrantFiled: February 3, 1987Date of Patent: March 8, 1988Inventor: Edward Orlando

Patent number: 4333402Abstract: A projectile (1) containing particles of interference material is fired pneumatically from a launching tube (2). Compressed air, which is supplied to the launching tube and acts on the rear face of the projectile during firing, is conducted both to a loading chamber (19) wherein the air pressure is maintained even after the projectile has left the firing tube, and also via the loading chamber to an expansion chamber (20) in which, after a specific time-lag corresponding with a certain launch height on the trajectory of the projectile, an over-pressure builds up which causes the expansion of the chamber to be initiated with simultaneous expulsion of the interference material from the projectile. The compressed air may also be conducted to the chamber (10) in the projectile wherein the interference material is accommodated, tightly packed, in order to enhance the dispersion thereof.Type: GrantFiled: October 23, 1979Date of Patent: June 8, 1982Inventors: Sven Landstrom, Kaj Lundahl
