DYNAMIC EFFECTS ON AIRBORNE ELECTRONICS

Airborne electronics as used in current aircraft are normally quite fragile in relation to the environment. The gap is being bridged by the use of isolators. The state of the art in ruggedization techniques for electronics is sufficiently advanced to preclude the use of isolators, but experience indicates that this advance is not being exploited in aircraft applications. This paper presents some specific vibration levels that general airborne electronics and component parts will withstand without the benfit of vibration isolators. Because of the large scope and complexity of the electronics area, it is to be realized that these susceptibility levels are only generalized indications. Also, applicability and function of vibration isolators is briefly discussed.
