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. WebThe MPDT has demonstrated its capability of providing specific impulses in the range of 1500–8000 sec with thrust efficiencies exceeding 40%. High efficiency (above 30%) is typically reached only at high power levels (above 100 kW); consequently, the steady-state version of the MPDT is regarded as a high-power propulsion option.
