Rocket Motor Blank, Liquid Fuel, American Rocket Society


Display Status:

This object is on display in the Rockets and Missiles exhibition at the Steven F. Udvar-Hazy Center in Chantilly, VA.

Collection Item Summary:

This rocket motor blank was one of six made for the American Rocket Society (ARS) in 1932 toward building, testing, and flying their first liquid-propellant rockets. It was not used but a similar blank, with lugs for propellant line connections, was used for ARS Rocket No. 1 that produced 60 pounds of thrust.

Of the six blanks, one made with lugs served as the motor for ARS Rockets No. 1 and 2. Another was used for the four nozzle motor for ARS Rocket No. 4. A third blank was fitted with a water jacket but never fired, while two others were used in the production of experimental motors but never finished. This object was donated to the Smithsonian in 1994 by the Thiokol Chemical Corp.
