Construction and Testing of a Mass Simulator for the ONR-301 EHIC Experiment
Abstract
An Energetic Heavy Ion Composition Instrument (EHIC) was built to be flown aboard either the TIROS 'I' or 'J' spacecraft. A Mass-Volume-Electric Simulator (Mass Simulator) is required in the event that the instrument is not operational at launch or to provide ballast for whichever spacecraft the EHIC will not be installed upon at launch. This 'smart dummy' was built and tested in 1990-91 and is awaiting delivery to GE for installation upon a designated spacecraft. The Mass Simulator must have the same mass, Center of Gravity (CG), approximate shape and thermal isolation properties as the EHIC instrument. It must be fabricated of flight quality materials and components, meet the electrical interface requirements relating to proper termination of harness cables and satisfy contamination control requirements as specified for all TIROS spacecraft instrumentation. Finally, it must meet the vibration constraints regarding first mode natural frequency (>100 Hz), successfully complete Qualification level vibration tests and be capable of surviving the Acoustic level vibration as specified.
