Delta-v is typically provided by the thrust of a rocket engine, but can be created by other engines. The time-rate of change of delta-v is the magnitude of the acceleration caused by the engines, i.e., the thrust per total vehicle mass. The actual acceleration vector would be found by adding thrust per mass on to the gravity vector and the ...
Delta V, follows a cyberpunk theme, taking place in a future where mega-corporations hire hackers to acquire data, which has become the currency of that era. The player starts the game as a captured hacker who is conscripted by Black Sun, one of the mega-corporations, to join the ranks of their online operatives and risk his life piloting programs through cyberspace to steal rival corporations ...
Delta-v in feet per second, and fuel requirements for a typical Apollo Lunar Landing mission. In astrodynamics and aerospace, a delta-v budget is an estimate of the total change in velocity (delta-v) required for a space mission. It is calculated as the sum of the delta-v required to perform each propulsive maneuver needed during
The actual acceleration of the craft is a-g and it is using delta-v at a rate of a per unit time. Over a time t the change in speed of the spacecraft is (a-g)t, whereas the delta-v expended is at. The gravity loss is the difference between these figures, which is gt. As a proportion of delta-v, the gravity loss is g/a.
The delta-v required is the vector change in velocity between the two planes at that point. However, maximum efficiency of inclination changes are achieved at apoapsis , (or apogee ), where orbital velocity v {\displaystyle v} is the lowest.
The applied change in velocity of each maneuver is referred to as delta-v (). The delta-v for all the expected maneuvers are estimated for a mission are summarized in a delta-v budget. With a good approximation of the delta-v budget designers can estimate the propellant required for planned maneuvers.

Delta-v required for Hohmann (thick black curve) and bi-elliptic transfers (colored curves) between two circular orbits as a function of the ratio of their radii The figure shows the total Δ v {\displaystyle \Delta v} required to transfer from a circular orbit of radius r 1 {\displaystyle r_{1}} to another circular orbit of radius r 2 ...
