In shooter games, rocket jumping is the technique of using the knockback of an explosive weapon, most often a rocket launcher, to launch the shooter into the air. [1] The aim of this technique is to reach heights, distances and speed that standard character movement cannot achieve.
This maneuver is also known as an orbital plane change as the plane of the orbit is tipped. This maneuver requires a change in the orbital velocity vector at the orbital nodes (i.e. the point where the initial and desired orbits intersect, the line of orbital nodes is defined by the intersection of the two orbital planes).
This maneuver is also known as an orbital plane change as the plane of the orbit is tipped. This maneuver requires a change in the orbital velocity vector ( delta-v ) at the orbital nodes (i.e. the point where the initial and desired orbits intersect, the line of orbital nodes is defined by the intersection of the two orbital planes).
The British satellite launcher Black Arrow was an example of a rocket that flew a preprogrammed pitch schedule, making no attempt to correct for errors in its trajectory, while the Apollo-Saturn rockets used "closed loop" inertial guidance after the gravity turn through the atmosphere.
The rocket was to be carried to launch altitude by a Boeing 747. [50] [51] The revised LauncherOne utilizes both the Newton 3 and Newton 4 rocket engines. [23] In December 2015, Virgin announced a change to the carrier plane for LauncherOne, as well as a substantially-larger design point for the rocket itself.
A launch from high altitude need not throttle back at max Q as it starts above the thickest portion of the Earth's atmosphere. Debora A. Grant and James L. Rand, in "The Balloon Assisted Launch System – A Heavy Lift Balloon", [ 11 ] wrote: "It was established some time ago that a ground launched rocket capable of reaching 20 km would be able ...
Once in orbit, a spacecraft may fire rocket engines to make in-plane changes to a different altitude or type of orbit, or to change its orbital plane. These maneuvers require changes in the craft's velocity, and the classical rocket equation is used to calculate the propellant requirements for a given delta-v .
Aerobraking then shortens the orbit into a circle. If the atmosphere is thick enough, a single pass can be sufficient to adjust the orbit. However, aerobraking typically requires multiple orbits higher in the atmosphere. This reduces the effects of frictional heating, unpredictable turbulence effects, atmospheric composition, and temperature.
