The CHARGE-2B sounding rocket, a joint Rome Laboratory-NASA project, Is intended to establish the feasibility of using charged particle beams as very low frequency antennas. To obtain control measurements of beam-generated waves in the ionosphere, Rome Laboratory has built the Diagnostic Free-Flyer (DFF) -- a wave receiver subpayload that will be ejected from the beam-emitting main payload during flight. It was necessary to design and fabricate a pneumatic payload ejection system capable of propelling the DFF at several meters per second relative to the main payload while not subjecting the on-board instruments to acceleration exceeding 10 g's. Calibration and reliability test data for t-he pneumatic payload ejector (PPE) are presented in this report. The calibration will be used together with accelerometer data to determine a payload separation versus time-of-flight profile for use in interpreting DFF wave data. Reliability data for the PPE are required to establish the flight-worthiness of the ejection system.... Sounding rocket technology, Payload separation mechanism, CHARGE-2B, Pneumatic actuator.
