Abstract

Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, Ahead of Print.
The development of aero engines with geared fans may require the use of an air/oil heat exchanger (AOHE) embedded within the bypass duct to dissipate heat from the power gearbox of the fan. It is important that the AOHE system is designed and installed to ...
