Comparison of Four Space Propulsion Methods for Reducing Transfer Times of Manned Mars Mission

, 2015
We assess the possibility of reducing the travel time of a manned mission to Mars by examining four different propulsion methods, and keeping the mass at departure under 2,500 tonnes, for a fixed architecture. We evaluated representative systems of three

Comparison of the Recoil of Conventional and Electromagnetic Cannon

Shock and Vibration, 2001
The recoil from an electromagnetic (EM) railgun is discussed and compared with that from conventional, propellant gas driven cannon. It is shown that, under similar launch conditions, the recoil of the EM gun is less than that of the powder gun; however,
