Abstract:
In order to improve the accuracy of retarded bombs released from high altitude, the MAU-146 AB Mechanical Set Band Release Timer was developed which allows the bomb to free fall in a low drag configuration for a pre-determined time and then forcefully open the retarder fins. The timer was designed and tested during a six-month period. The device is compatible with the retarder mechanisms of the MAU-91, MK-15, and the MK-82 ballute fin assemblies and is also readily adaptable to universal applications. The timer is settable from 2 to 60 seconds in one-second increments, and its output is a forceful 1-12-inch linear stroke capable of performing work. Sample timers were successfully subjected to both contractor and government environmental tests. Test results qualify the MAU-146 AB to continue flight tests on high performance aircraft. Units of this design functioned reliably and with an accuracy well within the or - 3 time limits. One hundred twenty-four MAU-146 AB Mechanical Set Band Release Timers were shipped to Eglin Air Force Base for evaluation. It was concluded from the program effort that the MAU-146 AB Mechanical Set Band Release Timer represents a significant universal design with general applications to retarded bombs and that the timer functions well within specifications. The MAU-146 AB has already been successfully employed as a universal tool by the Air Force to extend the timing range of the FMU-83B Mechanical Fuze and as a drogue release during special fuel-air explosive FAE tests.
