Structural Dynamic Response of AH-1G Wing with XM35 Weapon.
Abstract
The report contains an analysis and the numerical results which have been developed for predicting dynamic response of flexible helicopter structures excited by the recoil force of the XM35 weapon. This report is in four parts. The first part contains the analysis of the wing-gun combination alone. The wing is assumed to be clamped rigidly at its root. The recoil force is divided into three components which include the mean force, the sinusoidal component, and the random component. The wing is treated as a flexible structure with lumped masses. The second part of the report contains the analysis of the wing-gun combination but the wing is assumed to be supported elastically at its root. The third part contains the analysis of the total wing-gun combination plus the remaining helicopter structure by the Statistical Energy Analysis (SEA) method. The fourth part of the report describes a computer program which has been developed and the numerical results which have been obtained using the analysis in part one of this report.
