Design of Selected Helicopter Components for Ease of Repair
Abstract
This report examines the design of major helicopter components and its effect on the man-hour cost of field repair. Recommendations are developed for improving the field repairability of these components on future helicopters through improved applications of current technology and new design concepts. The study was accomplished in two phases. In the first, field surveys were conducted to identify significantly occurring repair actions in the field and the important elements of each repair task. Comments on repair problems were solicited from Army mechanics. Nine generic types of components on six helicopter models were investigated. Solutions available through improved applications of current technology were identified, and recommended design study projects were submitted for Army approval. In Phase 2, design studies were conducted for five generic types of parts found to be most significant from the standpoint of the man-hours they consume in repair and/or the number of complaints they received from mechanics in the field. Twenty-five design concepts were investigated. Each was subjected to an engineering critique that considered the effects on such factors as cost, weight, stress and performance.
