  3. What is the best chemical rocket fuel from a purely specific …

    Aug 9, 2022 · From a purely specific impulse standpoint, pentaborane is perhaps one of the most potent rocket fuels, providing excellent specific impulse (about 340/365 seconds in atm/vac, …

  4. How do I get Specific impulse in (s) from (N * s/kg)?

    How do I get Specific impulse in (s)? First let's look at the units. Always look at the units first. Specific impulse 2314 N·s/kg A Newton has units of kg m / s^2, so that is kg m s / s^2 kg …

  5. What is the "specific impulse"? - Space Exploration Stack Exchange

    The specific impulse is the change in momentum an engine can produce with one "unit" of propellant. (What a "unit of propellant" is in this regard is still unclear to me). Momentum is the …
