LVDC from Instrument Unit technical manual. The Launch Vehicle Digital Computer (LVDC) was a computer that provided the autopilot for the Saturn V rocket from launch, through Canary Islands orbit insertion, and the trans-lunar injection burn that would send the Apollo spacecraft to the Moon.
The rocket was fired from two rails; aiming was simple, behind a shield the layer on the right hand side pushed the apparatus in the direction of the target using a crude sighting device and the layer on the left locked the launcher before the rocket was fired using electrical ignition. A test battery was set up at Aberporth and other rocket ...
After the Gemini spun up to one revolution per second, Neil Armstrong regained control by switching from the main attitude control system to the reentry system. Mission rules required a landing as soon as possible once the reentry thrusters were used, causing an early end to the flight.
A gravity turn is commonly used with rocket powered vehicles that launch vertically, like the Space Shuttle. The rocket begins by flying straight up, gaining both vertical speed and altitude. During this portion of the launch, gravity acts directly against the thrust of the rocket, lowering its vertical acceleration.
Electron is a two-stage, partially reusable orbital launch vehicle developed by Rocket Lab, an American aerospace company with a wholly owned New Zealand subsidiary. [14] [15] Servicing the commercial small satellite launch market, [16] it is the third most launched small-lift launch vehicle in history.
The term solid rocket motor applied to the propellant, case, igniter and nozzle. Solid rocket booster applied to the entire rocket assembly, which included the rocket motor as well as the recovery parachutes, electronic instrumentation, separation rockets, range safety destruct system, and thrust vector control.
The rocket is launched using liquid hydrogen and liquid oxygen cryogenic propellants. Rocket propellant is used as reaction mass ejected from a rocket engine to produce thrust . The energy required can either come from the propellants themselves, as with a chemical rocket , or from an external source, as with ion engines .
Rutherford is a liquid-propellant rocket engine designed by aerospace company Rocket Lab [8] and manufactured in Long Beach, California. [9] The engine is used on the company's own rocket, Electron. It uses LOX (liquid oxygen) and RP-1 (refined kerosene) as its propellants and is the first flight-ready engine to use the electric-pump-fed cycle.
