Helicopter Transmission Oil Heat Rejection Investigation.

Abstract

This report presents the results of a feasibility and preliminary design study of integral cooling systems for helicopter main transmissions. The purpose of the study is to provide a method or methods whereby the requirements for remote external cooling systems no longer exist. The goal of the program is to define long-range solutions and/or expedient methods permitting simple retrofit to existing aircraft. While the primary effort centers around the heat rejection requirements of the main gearbox of the U.S. Army CH-54A crane helicopter, the adaptability of the most promising systems to other U.S. Army helicopters is also investigated. Several extremely advanced methods of gearbox cooling were investigated.
