DSTR/501-M62B Dynamic Interface Critical Speed Problem

Abstract

A dynamic interface problem was encountered during the Dynamic System Test Rig (DSTR) portion of the Heavy Lift Helicopter (HLH) program. This problem involved the dynamic incompatibility of the original designs of the Detroit Diesel Allison (DDA) 501-M62B engine and the Boeing Vertol (BV) DSTR shafting. Presented is a detailed discussion of the interface problem and the steps taken toward solution. Design modifications to both the engine and shafting were necessary to synthesize an acceptable drive train configuration. Recommendations are proposed for avoidance of engine/airframe interface problems in future programs.
