STATIC AND FLIGHT TESTING OF THE 2.75-INCH SLOW SMOKY ROCKET MOTOR

This report summarizes the development and testing work done at the Naval Weapons Center on the 2.75-inch Slow Smoky Rocket being developed jointly by NWC and the Jet Propulsion Laboratory, Pasadena. The program objective was to design, develop, and fabricate a smoke-producing rocket motor capable of providing a visual means of precisely locating targets from aircraft at high altitudes. Standard or state-of-the-art 2.75-inch FFAR (folding fin aircraft rocket) hardware was used, and the visual characteristic was provided by means of a smoke trail produced by a phosphorus sustainer grain contained within the rocket motor. Environmental tests, static firings, and ground-launched tests were conducted over a 9-month period at NWC to demonstrate the feasibility of the motor design. (Author)
