Moving to an All-Electric Aircraft System

Hitoshi Oyori, IHI Corporation, Japan

Hitoshi Oyori is a general manager of New Technology Project group, Aero engine, Space & Defense Business Area in IHI Corporation. He was born in Kyoto city, Japan in 1966. He graduated from the Department of Electrical Engineering, Ritsumeikan University in 1989 and received M.E. in 1991. He received his Ph.D. degree in 2014 from Department of Aeronautics and Astronautics, University of Tokyo. He worked for Nissan Motor Corporation, then moved to IHI Corporation associated with the business transfer from Nissan to IHI.

He joined H2A project, which is a current flag ship of Japanese launch vehicles, and developed the largest electric-mechanical actuator system for thrust vectoring control of the solid rocket booster as a chief engineer around 25 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 2018. 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).

He became the visiting professor of Akita University in 2018 and Akita prefectural university in 2020. He has been nominated as the top researcher in an electrification project for Regional Revitalization by Cabinet Office, Government of Japan.


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.
