4 hari yang lalu · The S-IVB burned for almost six minutes, giving the spacecraft a velocity close to the Earth's escape velocity of 25,053 mph (40,319 km/h). This gave an energy-efficient transfer to lunar orbit, with the Moon helping to capture the spacecraft with a minimum of CSM fuel consumption.
4 hari yang lalu · A rocket with a high exhaust velocity can achieve the same impulse with less reaction mass; however, the energy required for that impulse is proportional to the exhaust velocity. This means that mass-efficient engines require much more energy per unit mass.
2 hari yang lalu · Values beyond 40,000 metres (131,000 feet) per second are predicted for systems using electromagnetic acceleration. In engineering circles, notably in the United States, the effective exhaust velocity is widely expressed in units of seconds, which is referred to as specific impulse.
5 Ogo 2024 · We launch things into space by putting them on rockets with enough fuel — called propellant — to boost them above most of Earth’s atmosphere. Once a rocket reaches the right distance from Earth, it releases the satellite or spacecraft.
5 hari yang lalu · Rocket engines expel propellant to provide forward thrust that generates enough delta-v (change in velocity) to reach orbit. For crewed launch systems launch escape systems are frequently fitted to allow astronauts to escape in the case of emergency.
13 Ogo 2024 · Rocket Acceleration Calculator. Need help? Ask our AI assistant. Delta-V Formula. The following formula is used to calculate the delta-v of a rocket: ∆v = Ve * ln (mi / mf) ∆v = V e ∗ ln(mi/mf) Where ∆v is the change in velocity of the rocket (m/s) Ve is the exhaust velocity (m/s) mi is the initial mass of the rocket (kg)
16 Ogo 2024 · Escape velocity is essential for space travel, determining the speed a rocket must reach to exit Earth's (or any other celestial body's) gravitational influence. It also plays a role in the formation of celestial bodies, atmospheric retention, and the behavior of objects in the cosmos.
