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) FY2016
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 (ASACOC)
(1-b) Hybrid Fuel Cooled Oil Cooler (HFCOC)
(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. The technical specifications for the above components are released in order to support the validation test on the demonstrator engine test.
(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) High efficiency air heatsink by skybed forming
The parts of heat exchanger were produced by the metal (aluminum alloy) additive layer manufacturing technology.
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. The design concept of the oil flow control Valve was studied.
(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. The air fin design was optimized.
(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 thermal performance analysis result was validated by the performance test for the prototype of hybrid fuel cooled oil cooler.
