TESTS OF BALLISTIC DROP UNITS UNDER F-111A FLIGHT LOADS.
Abstract
Four Ballistic Drop Units (BDUs) were subjected to combined high-temperature static load tests which simulated the most severe F-111A flight loads. The BDUs tested were: BDU-8/B, BDU-12/B, BDU-18/B, and BDU-19/B. The BDU-19/B sustained no visible mechanical damage when subjected to 150 percent limit load in Test Condition 1. The rear suspension lug of the BDU-12/B became disengaged from the MAU-12 Bomb Rack at 93 percent limit load in test Condition 3 and a structural-steel simulated bomb rack was substituted for the remainder of the testing. The BDU-12/B sustained no visible mechanical damage, when subjected to 125 percent limit load in each of the three different test conditions. The BDU-8/B and the BDU-18/B sustained no visible mechanical damage when subjected to Test Conditions 2 and 3. The nose sections of both the BDU-8/B and the BDU-18/B collapsed at 124 percent and 110 percent limit load, respectively, in Test Condition 4.
