Definition of delta-v in English: delta-v(also delta-vee) noun mass nouninformal Acceleration. 〈非正式〉加速度 four hundred knots of delta-v 400节加速度。 Example sentencesExamples - From a technical standpoint, a mission to Phobos requires minimal delta-v, because of its small mass and the ability to use aerobraking in the Martian atmosphere.
- Further, they don't have the gravity-well problems which Mars and other planets have, and travel between asteroids will always be expensive in either time or delta-vee.
- The delta-v to achieve geostationary orbit from low Earth orbit is 3.6 km/s.
- Their main characteristics are warhead energy, acceleration, and total delta-v.
- Below acceleration durations of perhaps 50 to 100 milliseconds, the acceleration tolerance versus time curve tends to follow lines of constant velocity change, or delta-v.
Origin1960s: from delta (as a mathematical symbol denoting variation) + v for velocity.
