WebThe highest ISP bipropellant rocket engine in existence is the hydrogen/oxygen fuelled SSME which gives very high performance; but in terms of overall performance the dense-fuelled NK-33 is comparable due to better mass ratios; in spite of lower specific impulse. Principle of operation File:NASA bipropellant GPN-2000-000548.jpg The initial version, the Merlin 1A, used an inexpensive, expendable, ablatively cooled carbon-fiber-reinforced polymer composite nozzle and produced 340 kN (76,000 lbf) of thrust. The Merlin 1A flew only twice: first on March 24, 2006, when it caught fire and failed due to a fuel leak shortly after launch, and the second time on March 21, 2007, when it performed successfully. Both times t…

Web22 de fev. de 2024 · The current best vacuum hydrolox engine gets 470 seconds, or 89% of maximum. The main losses for that 11% are from the nozzle not extending to infinity. If the losses were from incomplete combustion, an improvement of 25% is most commonly stated ( one source ), which would lead to about a 2-3% increase--maximum. WebPretty expectedly, the nuclear engine takes the top spot. Closely behind is the Wolfhound, with the highest specific impulse of any chemical engine. After that, the big Rhino and efficient Poodle are nearly tied, with the Cheetah nipping at their heels and the Toroidal Aerospike after that. bishop photo
