WOX-5A ACCELEROMETER (ARTILLERY PROJECTILE COPPER-BALL ACCELEROMETER)
NAVAL ORDNANCE LAB WHITE OAK MD
Pagination or Media Count:
A multipurpose accelerometer mechanically measures artillery projectile setback, spin, barrel-slap and target-impact accelerations. Twenty- three copper-ball accelerometers mount in the aft 2.75 inches of a Mk 73 VT Fuze or T-227 CVT Fuze body. Eight accelerometers measure setback at frequencies from 7200 to 20,200 Hz eight similar accelerometers, opposite in direction, measure target impact three pairs of accelerometers measure barrel slap transverse acceleration at frequencies of 5680 and 8380 Hz one accelerometer measures spin angular acceleration at 1450 Hz or 1026 Hz.
