Download Paper - VIBRO-ACOUSTIC TESTING OF THE CLEMENTINE SPACECRAFT , Haughton James, Layher James, Haynes Robert, Hauser Joseph "VIBRO=ACOUSTIC TESTING OF THE CLEMENTINE SPACECRAFT." Small Satellite Conference, Logan Utah, September 1994.
The Clementine Spacecraft was launched on January 25, 1994 from Vandenberg Air Force Base. The spacecraft was designed, fabricated and tested by the Naval Research Laboratory. It used an array of lightweight optical sensors to perform the most extensive mapping of the lunar surface to date. This paper describes combined random vibration I acoustic (Vibro-acoustic) testing that was performed on both the Clementine Engineering Model and Flight Spacecraft. Axial
random vibration and high level acoustic loads were simultaneously applied in these tests. Acceleration response data from the Engineering Model test was used to refine preliminary component random vibration test levels. This test also qualified the design of the overall structure, subsystems and mechanisms for the
Vibro-acoustic loads seen during launch and ascent.
The Flight Spacecraft test was used as an overall acceptance and workmanship screen for the complete system prior to launch. Response data from the Flight Spacecraft test was also compared to the data from the Engineering Model test with some interesting results. This paper discusses the philosophy and execution of
these tests as well as the innovative techniques that were used. The paper also provides a brief overview of the full Clementine test program.
