Manacle Band Release Mechanisms

摘要

Manacle band release mechanisms have been used successfully in many sounding rocket applications. This report is a study of the basic design and describes modifications to increase the versatility of the manacle band for unique payload requirements. Two of the problem areas specifically addressed are space limitations and sealing of the payload at the separation plane. Separation methods critical to the successful operation of manacle systems are also described. Redundant bolt cutters, actuated by a pyrotechnic pressure cartridge, are used to release the manacle band. All parts of the bolt cutter assembly and the manacle band assembly were studied and tested when applicable to optimize the general design. A 14-inch diameter test fixture was fabricated to accomplish the tests. Keywords: Pyrotechnic pressure cartridges.
