1Advanced guns for future Naval systems such as Phalanx will incorporate innovative high-performance chemical and electrical propulsion concepts such as cased telescoped ammunition (CTA) and electro-thermal chemical (ETC) guns to achieve high ballistic performance. The combination of high performance, high firing rate (over 1000 rounds per minute per barrel), and extensive burst fire duration impo ...

RAPID FIRE HIGH VELOCITY AIRCRAFT GUN SYSTEMS HAVE MATURED TO THE POINT WHERE ONLY MARGINAL IMPROVEMENTS IN SYSTEM EFFECTIVENESS, WEIGHT REDUCTION, VOLUME REDUCTION, AND COST EFFECTIVENESS APPEAR ATTAINABLE. MOST OF THESE SYSTEMS ARE EXTERNALLY POWERED GATLING GUNS FIRING METALLIC CASED AMMUNITION, AND THESE COMPONENTS HAVE BENEFITED FROM OVER TWENTY-FIVE YEARS OF DESIGN REFINEMENTS AND MATERIAL I ...

A recently developed nonlinear controller(developed by the PI and the project consultant) called the theta-D method is the centerpiece around which an Integrated Guidance and Control scheme and a nonlinear filter technique are built to enhance the lethality of kinetic kill interceptors and offer means to increase the maneuver ratio advantage. Objectives of this proposal include development of a si ...

This proposal deals with new techniques for the guidance and control of Boost Phase of the missile defense. A new concept integrating the synergy between guidnace and coontrol is offered as an Integrated Guidance and Control approach; furthermore, a new nonlinear controller-filter called the theta-D technique is offered as the tool to solve the boost phase guidance and control problem for accurate ...

The objective of the proposal is to develop and extend to 6DOF missile-target engagement and dynamic models the integrated guidance-control and filtering-target-missile state estimation algorithms to achieve the hit-to-kill accuracy against targetsperforming evasive maneuvers, including spiraling motion. Two potential areas of algorithm development based on robust control and observation technique ...

Advanced GNC algorithms (estimators, guidance laws, controllers) for kinetic kill interceptors against advanced maneuvering threats will be developed and demonstrated. The advanced GNC algorithms will substantially increase the intercept accuracy against highly maneuvering targets while minimizing the interceptor divert acceleration and delta-v requirements. These advanced algorithms will be inc ...

The theoretical basis for current GNC algorithms implemented in interceptors has evolved from linear optimal control theory, which includes simple target maneuvers. These implementations suffer from lack of robustness when future threat target maneuvers are encountered, since the interceptor to target maneuver advantage required will exceed the maximums achievable. The spiraling and chaotic natu ...
