NOFBX推进剂技术的发展概况

Review of the development of NOFBX propellant technology

氧化亚氮基单组元复合物(nitrous oxide fuel blend,NOFBX)推进剂具有绿色无毒、能量高、可深度节流以及自增压等优点,是一种有前途的新型推进剂。总结了NOFBX推进剂相较于传统推进剂的优势和不足,介绍了国内外在NOFBX推进剂研制、不同量级的发动机设计、发动机热试车、防回火研究和冷却研究等方面的发展现状,提出了NOFBX推进剂发展的关键问题。

Nitrous Oxide Fuel Blend(NOFBX)is a promising propellant with merits of green,non-toxic,high energy,deep throttling,and self-pressurization.This paper summarizes the advantages and disadvantages of NOFBX propellant compared with traditional propellants.The development status of NOFBX propellant development,engine design of different orders of magnitude,engine hot test,anti-flashback research and cooling research at home and abroad are introduced,the key technical issues for the further development of NOFBX technology are proposed.
