Description:
A sounding rocket payload, free falling in space, with low angular body rates provides a near zero gravity environment. To efficiently utilize the time above the earth's atmosphere, a positive means of controlling angular body rates must be provided for the payload. A rate-control system (RCS) was designed at the Goddard Space Flight Center (GSFC) to meet the requirements of the Space Processing Applications Rocket Program and for use on the Black Brant-V sounding rocket. After the sounding rocket exits the atmosphere, the payload separates, the RCS reduces the initial angular rates to low levels and maintains the low levels until the payload reenters the atmosphere. The maiden flight of the RCS was aboard a NASA sounding rocket. The system performed as expected, and the payload experienced a low-G environment below 0.0001 G for 300 sec. This paper describes the design criteria, the components used, and the mode of operation.
