This nozzle is from an uncooled rocket motor of the American Rocket Society (ARS). It was damaged during a thirteen-second test on 2 June 1935 at Crestwood, New York, to determine the "heat resisting value of nichrome compared to the aluminum for the nozzle metal." Using liquid oxygen and gasoline, the motor's maximum thrust was 24.5 kg (54 lb) while the average was 16 kg (35 lb). The nozzle stood up "remarkably under the intense heat (c. 2,000 degrees C.)" and the "nichrome nozzles were definitely superior to the aluminum nozzles."
Between November 1932 and September 1934, the ARS attempted four launches with rudimentary rockets, two of which succeeded. Members decided that more could be learned by conducting static tests, which would also be less expensive. Static testing began in 1935 and continued until 1942. This nozzle was a gift of Peter van Dresser, an early member of ARS.
