Aero Engines and Space Operations
Rocket System
IHI has participated in the Japanese space development effort from the beginning, developing and producing turbopumps, a key components of rocket engines, gas-jet systems, both of which are embodiments of IHI's long-fostered technologies such as cryogenic-pump and turbomachinery. These activities were greatly expanded in space when the company acquired Nissan Motor Co., Ltd's Aerospace Division, a pioneer in solid rocket development in Japan. IHI is also playing an important role in development and construction of the Exposed Facilities of Japanese Experiment Module “KIBO”, which is a part of the International Space Station program. Furthermore, in the field of space experiment, IHI is now a supplier of the major experimental systems required for various international cooperative experiments.
Ground test facility
In addition to the LNG engine firing test facilities, we also possess test facilities for the satellite propulsion systems and control systems.
Liquid oxygen turbopump for the H-IIA rocket / LE-7A engine
This pump supplies the liquid oxygen needed to burn the hydrogen fuel in the rocket engines. Together with the liquid hydrogen turbopump, it forms the heart of the rocket.
Liquid hydrogen turbopump for the H-IIA rocket / LE-7A engine
This pump supplies the liquid hydrogen fueling the rocket engines. This forms the heart of the rocket. IHI provides the turbopumps for both the first-stage LE-7A engine and the second-stage LE-5B engine.
M-V rocket
The M-V rocket is one of the world's largest 3-stage solid fuel rocket with a diameter of 2.51 m and it is capable of launching a satellite weighing approximately 1.8 tons into a low-altitude orbit. The M-V rocket has been used to launch satellites developed for space exploration (1997-2006).

Development of bipropellant liquid apogee engine, etc., used to obtain geostationary orbit
The apogee engine with 500 N class thrust developed by IHI group has the highest level of performance in the world, rated as top by the clients all over the world along with the 22N thruster.
International Space Station
The experimental module “KIBO” of the International Space Station that has completed in 2009, is the first manned facility that Japan was in charge of development. The IHI group developed the extravehicular experimental platform as well as the extravehicular pallet for “KIBO”, and also developed the experiment racks and experimental devices installed in inboard labs.

HAYABUSA sample container
Asteroid exploration “HAYABUSA” was launched in 2003 on the M-V rocket No. 5, and the capsule was retrieved from the Woomera Prohibited Area in Australia in 2010. IHI group has the development and manufacturing technologies of the heat resisting materials (CFRP) that can withstand the relentless aerodynamic heating during the atmosphere entry. These materials will be used with the planetary exploration capsules to be produced in future.

Unmanned Space Experiment Recovery System （USERS）
USERS is an Unmanned Space Experiment Recovery System unmanned space experiment system that USEF has launched with the H-IIA rocket. IHI group is in charge of its recovery capsule part (REM) and the Super conduct or Gradient Heating Furnace (SGHF) onboard the REM. IHI group was also in charge of return operation and search and recovery mission, and successfully recovered the satellite from the orbit for the first time by Japan, at the Pacific Ocean east of Ogasawara Islands on May 2003.

Aircraft engines
IHI is the leading company of jet engines in Japan with a 60-70% share of the market. IHI is the primary contractor and manufacturer for the aircraft engines used by the Ministry of Defense, and participates in international collaborative projects that develop and supply various market segments, from super large to small engines for civilian aircraft. Utilizing these manufacturing technologies, IHI has acquired high reputation with its engine maintenance center in Asian markets. In the course of expanding strong demand for eco-friendly engines and its corporate responsibility, is now carrying out R&D on various next generation engines based on the most advanced technologies.
V2500 turbofan engine
This medium-size engine was developed in an international collaborative project involving Japan, U.S.A., U.K. and Germany, and has been installed on aircraft with 120 to 180 passenger seats such as the Airbus A319, A320, A321, and Boeing MD-90.
For this best-selling engine with over 5,000 orders to date, IHI supplies fan modules and low-pressure shafts, and also focuses its efforts on maintenance work.
