Abstract:

A test program was initiated to evaluate the capability of representative samples of the Gemini B Laboratory Module LM Transfer Tunnel and Blast Shield to withstand the pressure, temperature, and erosive environment caused by the impingement of the exhaust plume of a subscale 500 pound thrust solid propellant rocket motor. The subscale rocket motors enabled the retrorocket local ballistic properties to be duplicated, but did not produce the total loading of a full scale retrorocket motor. During this test program six tests were performed, one using an LM transfer tunnel test panel and five using blast shield test panels. In addition, two trial tests were performed in order that various pertinent test parameters could be verified prior to the actual tests. Author
