"Web8 Oct 2024 · A rocket's overall thrust-to-weight ratio is much less often quoted. It will generally be less than 10 (except in a few very unusual cases). It usually starts at somewhere between 1.2 and 1.5 at liftoff, increasing over the course of a stage's burn, as propellant is consumed; it varies with payload and mission. " - Rocketry isp

Web22 May 2024 · More often you'll see specific impulse called I s p and measured in seconds (but really meaning pounds-of-force-seconds-per-pound-of-mass); I s p in seconds times gravity at Earth's surface ( ≈ 9.81 m s 2) yields exhaust velocity. Share Improve this answer Follow edited May 21, 2024 at 23:53 answered May 21, 2024 at 23:06 Russell Borogove WebIsp is the impulse per unit weight of propellant. So take the Isp, in seconds, and multiply by the propellant weight in whatever force units you like (in your case Newtons) and you get the total impulse in N-s. Isp is basically a function of the propellant composition itself. Total impulse is related to how much propellant you have.

Web13 May 2024 · Mathematically, the Isp is a ratio of the thrust produced to the weight flow of the propellants.
