Abstract

This is a proposal for the design, fabrication and test of a 155mm munition which uses aerodynamic lift to greatly extend its range. Previously flight-tested BLAM (Ballistic Launched Adaptive Munition) technology will be used to provide solid state, smart material. aerodynamic control surfaces with bandwidths of several hundreds hertz. The required munition control authority is greatly reduced because attitude errors are corrected before they become large. The solid state BLAM actuators are very light, low power, inexpensive, and reliable A 155mm BLAM will be fabricated and wind tunnel tested in Phase I. The main goal of the Phase I effort is to develop a BLAM compatible guidance system. A broad range of guidance concepts will be considered including : (1) a simple replacement of movable canards on the despun portion of the competent munition ATD; (2) a munition with reduced spin rate that does not require despinning the guidance package or any canards; (3) an RF beam rider munition requiring no despinning, canards, or INS/GPS package. The Phase II effort will fabricate and flight test a 155 mm, guided BLAM munition. BLAM technology has a broad range of applications using a broad range of guidance systems from sniper rifles to BMD.
