DEVELOPMENT OF APPARATUS FOR MICROMETEORITE MEASUREMENTS
AIR FORCE CAMBRIDGE RESEARCH LABS L G HANSCOM FIELD MASS
Technical details for a specific detection system making use of the acoustic technique are given. This system was tailored in design to the unique requirements of a specific satellite vehicle. Information is also presented concerning the instrumentation of the payload for a Nike-Cajun rocket AA6.104C prepared for an experimental investigation of the influx of micrometeoritic material. The available techniques for calibration and testing of acoustic detection systems are discussed, and the electrical and mechanical features of a special electronic simulator which facilitates calibration in terms of effective momentum transfer are discussed in detail. Some practical implications of the investigation with regard to the design of similar equipment for future experiments are discussed, and a proposal for improvement of the uniformity of response for the acoustic sensor assembly i offer d. Finally, a number of miscellaneous support activities concerned with the prime investigation are covered in some detail. Author
