|20150345909||TRAJECTORY MODIFICATION OF A SPINNING PROJECTILE BY CONTROLLING THE ROLL ORIENTATION OF A DECOUPLED PORTION OF THE PROJECTILE THAT HAS ACTUATED AERODYNAMIC SURFACES - 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.||12-03-2015|
|20150253112||GUN SIGHT FOR USE WITH SUPERELEVATING WEAPON - A gun sight for use with a weapon configured for super elevation is disclosed herein. The gun sight includes, but is not limited to, an imaging system that is configured for rotation. The gun sight further includes a drive mechanism that associated with the imaging system and that is configured to rotate the imaging system. The gun sight further includes a gyroscope associated with one of the weapon and the imaging system. The gun sight still further includes a processor that is communicatively coupled with the drive mechanism and the gyroscope. The processor is configured to control the drive mechanism to rotate the imaging system in a manner that causes the imaging system to maintain an initial angular orientation based on information provided by the gyroscope when the weapon is superelevated.||09-10-2015|
|20130097995||SYSTEM AND METHOD FOR CONTROLLING AN OBJECT TRAVELING THROUGH EXOATMOSPHERIC SPACE - A system for controlling an object traveling through exoatmospheric space is disclosed herein. The system includes, but is not limited to, a pressure vessel, a pair of solid propellant grains associated with the pressure vessel that is configured to direct a gas into the pressure vessel during combustion, an exhaust nozzle that is in fluid communication with the pressure vessel, and a valve that is coupled with the exhaust nozzle and that is configured to selectively obstruct the gas from venting through the exhaust nozzle.||04-25-2013|
|20120211593||TRAJECTORY MODIFICATION OF A SPINNING PROJECTILE - 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.||08-23-2012|
|20120076443||METHOD OF PREPARING A STABILIZED NITROCELLULOSE ARTICLE - A method for preparing a stabilized nitrocellulose article includes providing a nitrocellulose-containing mat of fibers. The nitrocellulose-containing mat of fibers is treated with a solution that comprises a solvent and a stabilizer to produce the article. The stabilizer is soluble in the solvent. The solvent dissolves the stabilizer and the nitrocellulose in the nitrocellulose-containing mat of fibers is substantially insoluble in the solvent at ambient pressure and temperature. An inflatable bag comprises a shell and the stabilized nitrocellulose article. The shell is formed from a foldable material and has an outer surface and an inner surface. The inner surface defines an interior cavity of the inflatable bag. The stabilized nitrocellulose article is disposed upon the inner surface of the shell in the interior cavity and is foldable in conformity with at least one fold of the shell.||03-29-2012|
