WebDelta-v (more known as " change in velocity "), symbolized as ∆v and pronounced delta-vee, as used in spacecraft flight dynamics, is a measure of the impulse per unit of spacecraft mass that is needed to perform a maneuver such as launching from or landing on a planet or moon, or an in-space orbital maneuver. WebMay 22, 2024 · Alternate Wars gives this formula for computing the length of a rocket burn: Δ T = M L E V F ( 1 − e − Δ V E V) Where: Δ T: Length of burn in seconds M L: Total mass of the rocket at the beginning of the burn (often written m 0) E V = Exhaust Velocity in meters/second (often written as v e ). F: Thrust of the rocket in Newtons.
