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 ...
The Electromagnetic Aircraft Launch System (EMALS) is a type of electromagnetic catapult system developed by General Atomics for the United States Navy. The system launches carrier-based aircraft by means of a catapult employing a linear induction motor rather than the conventional steam piston , providing greater precision and faster recharge ...
Constructed in 1976 and 1977, Mass Driver 1 was an early demonstration of the concept of the mass driver, a form of electromagnetic launcher, which in principle could also be configured as a rocket motor, using asteroidal materials for reaction mass and energized by solar or other electric power.
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. 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 orbit.

The rocket consists of the warhead and fuse, a thrust stabilising system, a rocket motor and the tail section. The rocket motor is a single chamber, solid rocket motor with an advanced hydroxy-terminated polybutadiene (HTPB) composition rocket propellant. The stabilising fins are folded inside the launch tube and open once the rocket leaves the ...
In June 2020, with a new Electron launch vehicle built every 18 days, Rocket Lab was planning to deliver monthly launches for the remainder of 2020 and into 2021, including the company's first launch from Wallops LC-2 in 2023 and a mission to the Moon for NASA aboard Electron and Rocket Lab's spacecraft bus platform Photon in 2022.
Competing with an upgrade of a number of Greece's rocket artillery M270 MLRS by Lockheed, as part of a modernization program of the rocket artillery forces. [ 30 ] [ 31 ] If purchased, the Hellenic Army will acquire 36 or 40 [ 32 ] of the European version, EURO PULS MLRS, [ 32 ] in a deal of €600-700 million, with the construction of some of ...
