However, the non-linear nature of the rocket equation still makes the payload fraction for such a vehicle significantly greater than that of a conventional rocket unassisted by electromagnetic launch, and a vehicle with high available weight margins and safety factors should be far easier to mass-produce cheaply or make reusable with rapid ...
Cross-section diagram of a pulsed inductive thruster. [1] The gas is puffed inward through a central nozzle, towards the flat electromagnetic coil where it is ionized. [2] The plasma (pink) is then accelerated to the rear by the Lorentz force. A pulsed inductive thruster (PIT) is a form of ion thruster, used in spacecraft propulsion.
A pulsed plasma thruster (PPT), also known as a Pulsed Plasma Rocket (PPR), or as a plasma jet engine (PJE), is a form of electric spacecraft propulsion. [1] PPTs are generally considered the simplest form of electric spacecraft propulsion and were the first form of electric propulsion to be flown in space, having flown on two Soviet probes ...
A mass driver or electromagnetic catapult is a proposed method of non-rocket spacelaunch which would use a linear motor to accelerate and catapult payloads up to high speeds. Existing and proposed mass drivers use coils of wire energized by electricity to make electromagnets , though a rotary mass driver has also been proposed. [ 1 ]
6 kW Hall thruster in operation at the NASA Jet Propulsion Laboratory 3D sketch of an electromagnetic propulsion fusion plasma thruster. Spacecraft electric propulsion (or just electric propulsion) is a type of spacecraft propulsion technique that uses electrostatic or electromagnetic fields to accelerate mass to high speed and thus generating thrust to modify the velocity of a spacecraft in ...
Space Electric Rocket Test, suborbital (31 min), the first demonstration of an ion engine in space - only the mercury engine by NASA was operated Program 661A Flight B: 29 Aug 1964: 29 Aug 1964: Ion engine: 1: Cesium: USAF: EOS: Suborbital, experimental test (19 min operation) Zond 2: 30 Nov 1964: 14 May 1965: Pulsed plasma thruster: PTFE ...
VASIMR, short for Variable Specific Impulse Magnetoplasma Rocket, uses radio waves to ionize a propellant into a plasma. A magnetic field then accelerates the plasma out of the engine, generating thrust. A 200-megawatt VASIMR engine could reduce the time to travel from Earth to Jupiter or Saturn from six years to fourteen months, and from Earth ...
As part of the CCEMG program, UT-CEM designed and developed the Cannon-Caliber Electromagnetic Launcher, a rapid-fire railgun launcher, in 1995. [30] Featuring a 30-mm roundbore, the launcher was capable of firing three, five-round salvos of 185-g launch packages at a muzzle velocity of 1850 m/s and a firing rate of 5 Hz.
