Aircraft Gunfire Vibration. The Development and Prediction Methods and the Synthesis of Equipment Vibration Techniques.
Abstract
The study describes in-house efforts that comprise two primary objectives. (1) the development of a prediction rationale for estimating the magnitude and character of gunfire induced, structurally-borne vibration which, in turn, represents a definition of equipment vibration inputs, and (2) the synthesis of a laboratory vibration test procedure which may be used to qualify future equipment. Power analogies, relating gunfire blast to structural response, are meshed with a spatial parameter to describe vibration levels that are functionally related to the gunfire blast pulse in terms of gun configuration, muzzle energy, gunfire rate, and the vector distance separating the equipment from the gun muzzles. A basic, normalized, test level function has been synthesized and integrated into a laboratory vibration test procedure. (Author)
