Environmental Vibration Testing of Helicopter Stores and Equipment to the Procedures Outlined in MIL-STD-810C

The MIL-STD-810C environmental vibration test requirements for internal and external equipment installed on helicopters are presented. Shortcomings in these requirements and how they can result in unnecessary weight and cost penalties during design without producing reliable performance under realistic conditions are discussed. Emphasis is placed on the application of the test-fix-test philosophy during engineering development. Examples of its application to two current store development programs are explained and test results presented. Recommended changes to MIL-STD-810C are made and the need for Innovative engineering solutions to current problems are discussed.
