Webb22 maj 2024 · At high propulsion force, f, the particles move as a fluid as before, with the time series of the mean kinetic energy showing typical Brownian fluctuations (Fig. 2d). Webb6 okt. 2024 · First, the greater the exhaust velocity of the gases relative to the rocket, ve, the greater the acceleration is. The practical limit for ve is about 2.5 × 103m / s for conventional (non-nuclear) hot-gas propulsion systems. The second factor is the rate at which mass is ejected from the rocket. This is the factor (Δm / Δt)ve, with units of ...
