Outline of Final Research Achievements

In order to develop a high performance microthruster for small satellites, we proposed a bipropellant thruster using nitrous oxide (N2O) and dimethyl ether (DME) as propellant. The thruster has a premixer to enhance performance and downsize the thrust chamber. A 0.4-N class thruster was prototyped to show that the thruster produce thrust and to evaluate the performance. A two-turn coil-type premixer was designed to mix N2O and DME, and numerical simulation showed that the premixer mixed N2O and DME. Thrust measurement showed that characteristic velocity efficiency was 84.5% at O/F=3.5, at which the thruster theoretically produced the maximum specific impulse of 290 s.

Academic Significance and Societal Importance of the Research Achievements

現在,大学や企業により重量が100 kg程度の小型衛星が製作され,打ち上げられるようになった.小型衛星は,製作コストだけでなく打ち上げコストも大幅に削減できるため,多数の小型衛星によるコンステレーションが可能となり,比類のないミッションを実現しうる.一方で,適合する推進機が少なく,多くの小型衛星は弾道飛行に甘んじてきた.そこで,小型軽量で環境適合性に優れる高性能なマイクロ推進機の実現のため,毒性が極めて低い液化ガスであるため亜酸化窒素とジメチルエーテルを推進剤とし,予混合により小型化を実現することを着想した.本研究は,小型衛星に適合するロケット推進機を創出し,小型衛星の発展に資するものである.
