Aero Engines


IHI is Japan’s leading maker of jet engines, with a market share of between 60% and 70%. We are the primary contractor and manufacturer for aircraft engines used by the Ministry of Defense. We collaborate in international projects to develop and supply large and small engines, components, and modules for all types of civilian aircraft. We have leveraged our experience and manufacturing technologies to provide maintenance for all types of engines. We are considered Asia’s core maintenance center. To meet the growing demand for more eco-friendly engines and fulfill our corporate responsibility, we are helping to develop next-generation engines that draw on our advanced technologies.

Rocket Systems and Space Exploration

IHI has participated in Japan’s space development effort from the outset. We have applied our cryogenic-pump and turbomachinery and other technologies to develop and manufacture the turbopumps and gas-jet systems crucial to successful rocket launches. Our involvement in Japan’s space program expanded significantly in 2000, when we acquired Nissan Motor’s Aerospace Division, a pioneer in solid-fuel rocket development in Japan. We play an important role in developing and constructing the Exposed Facilities of the KIBO Japanese Experiment Module, which is a part of the International Space Station program. We support experiments in space by supplying experimental systems needed for cooperative international projects.
