Innovative Motion Measurement Package (M2P) for Guided and Un-Guided Munitions


Performance of future munitions are dependent upon the accurate estimation of the airframe’s angular motion, acceleration about each axis, velocity and roll position relative to up. The M2P will reside within the munition airframe and measure actual projectile/airframe properties, which can be used by the munitions guidance package and/or fuzing system. The M2P technology can utilize conventional sensor technology but however, must also include novel technology that will enhance measurements as compared to current methodologies. Data such as launch conditions need to be accurately predicted in order for the M2P package to be able to integrate rates and accelerations in order to accurately predict the projectile’s attitude. The projectile’s M2P package shall not include GPS. The M2P sensor technology needs to function during gun launch shock environment and reliably measure, collect, and transmit data to the appropriate munition sub-system. The solution must be of such small size as to fit within the very limited volume claim (ideally within a 1 cubic inch volume) of the airframe and utilize existing power supply (ideally less than one watt). Life expectancy of the technology shall be at least 20 years. PHASE I: Identify all gun launch environmental effects and factors the projectile experiences. From these factors the contractor shall formulate and laboratory verify the technologies that are capable of accurately measuring the motion of the projectile during and after gun launch. The contractor will perform and document design analyses to demonstrate compliance with requirements listed above. The results of Phase I will include an engineering analysis of alternatives noting the design capabilities and limitations and recommendations for the Phase II effort, as well as recommendations for the physical prototypes to be built in the laboratory and subjected to laboratory functional testing. PHASE II: Based on success in Phase I, the contractor shall refine the selected design(s) to meet functional and environmental requirements. The contractor will design and build a minimum of 10 prototypes and provide to the government. At the Government’s discretion these prototypes may undergo air and/or rail gun testing culminating in a ballistic test (live fire). Deliverables include the 10 prototypes, an engineering report on the design selected in the contractor’s format. PHASE III: The topic author envisions that the LOS/BLOS Division within ARDEC’s Munitions Engineering and Technology Center will incorporate and test the developed technology in a time-fuzed munition. A need may exist to provide analysis, instructions, process control documents, and design that can be used by Army engineering to integrate the Phase II technology into a selected munition for further performance evaluations. To this end, the contractor may be requested, if funds are available, to design and build a minimum of 10 prototype sensor packages to be integrated into an Army selected munition. This munition may undergo air and/or rail gun testing culminating in a live-fire ballistics test.
