Overspeeding characteristics of turbomachinery for gas generator cycle air turbo ramjet engine
Autor: Ryojiro Minato, Daisuke Nakata, Masaharu Uchiumi, Ryoji Imai, Kazuyuki Higashino
Publikováno v: Propulsion and Power Research, Vol 11, Iss 4, Pp 444-456 (2022)
The main interest in the current study focuses on the possibility of overspeeding for the gas-generator cycle air turbo ramjet (GG-ATR) engine. The authors developed the air turbo ramjet engine and investigated its compressor performance. Based on th

Automatically Controlled Frequency-Tunable rf Plasma Thruster: Ion Beam and Thrust Measurements
Autor: Kazunori Takahashi, Ryoji Imai, Kengo Hanaoka
Publikováno v: Frontiers in Physics, Vol 9 (2021)
A fast and automatically controlled frequency-tunable radiofrequency (rf) system is installed in an rf plasma thruster consisting of a stepped-diameter insulator source tube wound by a single-turn loop antenna and a solenoid providing a magnetic nozz

Basic Study on Thermodynamic Vent System in Propulsion System for Future Spacecraft
Autor: Ryoji Imai, Kazuaki Nishida, Osamu Kawanami, Takehiro Himeno, Yutaka Umemura
Publikováno v: Microgravity Science and Technology. 32:339-348
In planned planetary explorations, cryogenic liquids such as liquid hydrogen (LH2), liquid oxygen (LOX), and liquefied natural gases (LNG) are used as fuel and oxidants in the propulsion systems of spacecraft. Such explorations require long-term stor

Improvement of resistance to oxaliplatin by vorinostat in human colorectal cancer cells through inhibition of Nrf2 nuclear translocation
Autor: Shota Tanaka, Mika Hosokawa, Ai Tatsumi, Shiho Asaumi, Ryoji Imai, Ken-ichi Ogawara
Publikováno v: Biochemical and biophysical research communications. 607
Vorinostat (suberoylanilide hydroxamic acid: SAHA), a histone deacetylase inhibitor, has potential benefit of improving the resistance to conventional other anti-cancer drugs. This study was aimed to clarify whether SAHA improves the resistance to ox

One-dimensional Droplet Model for Prediction of Jet-tip Height of Subcooling Mixing Jet for Cryogenic Propellant Storage Tank
Autor: Yutaka Umemura, Ryoki Matsushima, Takehiro Himeno, Kentaro Takeda, Ryoji Imai, Osamu Kawanami
This study proposes a one-dimensional droplet model to predict the jet-tip height of a subcooling mixing jet issuing from the bottom of a cryogenic propellant storage tank. Cryogenic liquids, such as liquid hydrogen and liquid oxygen, are used as pro
