7Overspeeding characteristics of turbomachinery for gas generator cycle air turbo ramjet engine显示文摘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 those data,the authors developed the analytical code for the air turbo ramjet engine,which calculates the performances of turbomachinery,gas-generator,and ram combustor.The previous study described that the rotor overspeeding would not occur in the air turbo rocket engine.However,the current results show that degraded ram combustion can decrease the compressor pressure ratio and the compressor power.This reduced compressor power can cause overspeeding for the air turbo ramjet engine.The experimental results of compressor power and turbine inlet pressure support those analytical results.Ryojiro Minato Daisuke Nakata Masaharu Uchiumi Ryoji Imai Kazuyuki Higashino 2022Propulsion and Power Research2022,11,4:0
8Low toxic nitromethane based monopropellant for gas generator cycle air turbo ramjet engine显示文摘The present study proposes ethanol-nitromethane mixture as a safe, storable, andlow toxic monopropellant for a gas generator cycle air turbo ramjet engine and evaluates itspropulsion performance. The present study proposes that nitromethane is mixed with ethanolto adjust gas generator combustion temperature. The author developed the computational codefor the present analysis and verified its accuracy. The specific thrust of ethanol-nitromethane isnearly identical to that of ethanol-liquified oxygen and is higher than methanol-hydroxylammonium nitrate aqueous solution and hydrazine. Hydrazine has the highest Ispamong the propellants in the present analysis. However, Isp of ethanol-nitromethane is nearlyequal to that of ethanol-liquified oxygen and higher than those of methanol-hydroxylammonium nitrate aqueous solution, and hydroxyl terminated polybutadiene-ammonium perchlorate. With the propellant-to-air ratio range in the present study, ethanol-nitromethane has the stoichiometric condition at the ram combustor around the propellant-to-air ratio range from 0.2 to 0.25 and can obtain high ram combustion temperature. This resultis favorable for ethanol-nitromethane because it improves the specific thrust and the specificimpulse. Therefore, ethanol-nitromethane can be a promising low-toxic liquid monopropellantfor the air turbo ramjet engine.Ryojiro Minato 2022Propulsion and Power Research2022,11,3:0
