英文要約Title: Research and Development Project for Advanced Aircraft Systems toward Practical Application/Development of Heat Management System for new generation aero-engines (FY2015-FY2017) FY2015 Annual Report

(1) Project Purpose:
The purpose of this project is to develop the high efficiency, light weight and competiveness heat management system that consist of the following components:
(1-a) Advanced Surface Air Cooled Oil Cooler
(1-b) Hibrid Fuel Cooled Oil Cooler
(1-c) Oil Flow Control Valve
(2) Specification of the components:
The design specification of the above components for next generation and fuel efficient aero-engines was reviewed and discussed with the engine manufacturer. Heat load for next generation and fuel efficient aero-engines will be increased and it will be two or three times than that for conventional aero-engines.
(3) Research of Manufacturing process and material:
New manufacturing technology and material were being researched for the above components. The following manufacturing technologies were assessed by means of trying to manufacture a prototype units and/or partial test units and investing them.
(3-a) Extrusion multi-hole pipe of aluminum alloy
(3-b) Folding fin forming of aluminum alloy plate
(3-c) Press working of aluminum alloy heatsink
(3-d) Photo etching of aluminum alloy
(3-e) Diffusion boding of aluminum alloy
(3-f) FSW (Friction stir welding) of aluminum alloy
Prototypes of heat exchanger were produced by the metal (aluminum alloy) additive layer manufacturing technology and they were subjected to performance test.
A manufacturer of Oil Flow Control Valve was selected. They were required to have an experience and pedigree for the development and production of a similar flow control valve on aerospace application, because the oil flow control valve would be mounted on an aero-engine which should require high reliability under a special environmental condition.
(4) Development of thermal performance model:
(4-a) ASACOC:
Numerical study (CFD analysis) had conducted to clarify the effect of the air flow around the air fins of the surface coolers.
(4-b) HFCOC:
The thermal performance model for the hybrid fuel cooled oil cooler which was integrated plate & fin type heat exchanger and shell & tube type heat exchanger. The hybrid fuel cooled oil cooler was being designed by this thermal performance model.
