Relative Vulnerability and Cost-Effectiveness Study of Transmission Oil Heat Rejection Systems

Abstract

This report describes the study of nine different methods, using the current state of the art, for dissipating the heat rejected into the oil in the forward transmission of a CH-47 helicopter. Five fluid heat transport systems and four dynamic heat pump and refrigeration systems were studied. In every case, the system under study was compared with the present production CH-47 oil- cooling system, which was used as a baseline for purposes of comparison.
