UTokyo

Company Profile

The University of Tokyo was established in 1877 as the first national university in Japan. As a leading research university, The University of Tokyo offers courses in essentially all academic disciplines at both undergraduate and graduate levels and conducts research across the full spectrum of academic activity. The university aims to provide its students with a rich and varied academic environment that ensures opportunities for both intellectual development and the acquisition of professional knowledge and skills. The research will be conducted at Department of Aeronautics and Astronautics in Graduate School of Engineering. The history of our Department is divided roughly into two eras. The first period was started in 1918 and was closed immediately after the Second World War. After reopening in 1954, it was reorganized and extended to the present state with the recent remarkable development in the fields of aeronautics and space technology. The graduate school education is more weighed nowadays responding to the recent technology sophistication.

Contribution to HIKARI

The impact of emission from pre-cooled turbo jet engine (PCTJ), which is developed by JAXA, on atmosphere is investigated experimentally and numerically. The attention will be paid to the reaction behavior of NOx and H2O in the stratosphere, which is emitted from hydrogen-fuelded PCTJ. The outline of our research is as follows;

  • Establish chemical analysis model for exhaust gas of hydrogen jet engines and high altitude atmosphere.
  • Conduct a sub-scale experiment to evaluate the chemical analysis model. This will be done by analyzing with Laser Induced Fluorescence (LIF) the behavior of H2/air combustion products when introduced in a vacuum chamber simulating high altitude conditions.
  • Estimate environmental impact of hydrogen jet engines with various equivalence ratios, simulating both ramjet and pre-cooled turbojet.

University of Tokyo is contracted with the EC under the Grant Agreement No 313987 and being funded by the METI (Ministry of Economy, Trade and Industry) and other concerned Japanese authorities, in accordance with Japanese laws and regulations.
