Acceleration erroneous detection prevention device of re-entry device and method of preventing erroneous acceleration detection

摘要

PROBLEM TO BE SOLVED: To provide a reentry vehicle acceleration detection error prevention apparatus capable of implementing each sequence of a reentry vehicle at appropriate timing even without any electrical interface between a space vehicle as a mother vehicle and the reentry vehicle.SOLUTION: An acceleration detection error prevention apparatus for a reentry space vehicle 12 separably installed in a space vehicle that serves as a mother space vehicle so as to reenter the atmosphere from outer space is provided. A controller 18 controls acceleration data acquisition means 22 to stop acquiring acceleration data from acceleration measuring means 14 or not to execute a determination process based on the acceleration data for a predetermined time period from time at which the acceleration measuring means 14 measures an impact acceleration until time at which the influence of the impact acceleration is eliminated if the acceleration measuring means 14 measures the impact acceleration, the impact acceleration occurring when the space vehicle reenters the atmosphere from the outer space to be subjected to destruction.
