HYDRA PROGRAM, A SHORT-RANGE TELEMETERING ROCKET FOR MEASUREMENT OF UNDERWATERNUCLEAR-BURST PLUME RADIATION.
Abstract
An instrument system was developed for the measurement of beta and gamma radiation fields in and adjacent to the water column and plumes ejected into the atmosphere by an underwater nuclear explosion. The system consists of a rocket with payload so fired that it traverses the area of interest in a near-vertical trajectory at the proper time. The payload consists of two gamma and one beta radiation transducer, an FM-FM multiplex transmitter, and an associated power supply. The rocket motor is a standard Mk. 10, Mod. 6 HVAR fitted with three different sizes of drag cone to achieve the desired trajectories. A zero length launcher is used. A receiving and recording station for the output of the transmitter also was designed. Nine test flights were made, three of which contained payloads. Sufficient trajectory information was obtained from these flights to establish a reasonably accurate set of drag coefficients for the three different sizes of drag cones. This information allows the calculation of trajectory and range for launch elevation angles other than those used in the test flights. (Author)
