Abstract : Small-scale experiments to determine the feasibility of suppressing explosive-mode failures (failures that occur 1/4 to 1/2 sec after ignition) of the Lance propulsion unit have shown that the severity of both heterogeneous and premixed reactions can be reduced by incorporation of fibrous materials into the reaction zone. Approximately 100 tests were run in each of three experimental arrangements designed to simulate various modes of fuel-oxidizer interaction. Several fiber sizes of copper, bronze, steel, aluminum, and glass were used. Results indicate glass wool to be equal to or superior to all other materials that were tested in its ability to suppress the severity of reaction. (Author)
