FM Telemetry for Multiple Force Measurements on Free-Flying Models

Abstract

CaCN )The extension of the FM telemetry technique to provide simultaneous CN O 2 a=o measurements of four forces acting on a free-flight aerodynamic model COb'collector-to-base plus collector stray capaciis reported. Developments and procedures required to achieve the tance accuracy, linearity, and stability necessary for obtaining dynamic C, total effective capacitance in the tuned cirstability coefficients are described. System accuracy is believed to be cuit IEEE TRANSACTIONS ON AEROSPACE AND ELECTRONIC SYSTEMS
