Moving to an All-Electric Aircraft System

Tomoya Inoue, IHI Corporation, Japan

Tomoya Inoue is a manager of No.1 Project group, Civil Engine Engineering Department, Aero engine, Space & Defense Business Area in IHI Corporation. He was born in Kanazawa city, Japan in 1969. He graduated from the Department of Electrical Engineering, Kyoto University in 1992. He worked for Nissan Motor Corporation, then moved to IHI Corporation associated with the business transfer from Nissan to IHI.

He joined Epsilon project, which is one of Japanese flag ship launch vehicles, and developed the avionics system including electrical power management system, guidance and control system, instrumentation and RF communication system and electric-mechanical actuator system for thrust vectoring control of the solid rocket booster as a chief engineer around 10 years ago. He has been in charge of the project of More Electric architecture for Aircrafts and Propulsion (or MEAAP) and has been the project manager since 2021. And then he manages the Japanese national project of aircraft systems’ electrification and electrified propulsion of hybrid system of NEDO (New Energy and Industrial Technology Development Organization).


It is expected that the number of aircraft in fleet increases nearly double in the next 20 years due to a doubling of passengers. On the other hand, the International Air Transport Association (IATA) sets a target of a reduction in net aviation CO2 emissions of 50% by 2050, relative to 2005 levels. In order to achieve it, we need to not only improve conventional technology, but also realize the innovative aircraft system that makes environmental impact reduce dramatically while maintaining the aircraft safety and economical aspect.

MEAAP (The More Electric Architecture for Aircraft and Propulsion) focuses on the achievement of significant advantage in fuel efficiency by optimizing the aircraft system including engine, and MEAAP project aims to improve safety, environmental friendliness, and economic benefits with innovations that integrate electrical power management and thermal management for aircraft. IHI is trying to develop an all-electric system for the engine and aircraft of the future within the next decade or two.

This course introduces an overview of the MEAAP concept and IHI all electrical system innovations.
