Launch to Space With an Electromagnetic Railgun
Many advances in electromagnetic (EM) railgun and power supply technology have been made in recent years. Laboratory experiments with railguns have demonstrated muzzle velocities of 2–3 km/s and muzzle energies 8 MJ. The extension of this technology to the muzzle velocities ( 7500 m/s) and energies ( 10 GJ) needed for the direct launch of payloads into orbit is very challenging, but may not be ...
متن کاملElectromagnetic Launch Optical Telemetry Feasibility Study
Results of a preliminary study to evaluate the feasibility of optical telemetry on an EM launched projectile are discussed. At issue are the relative intensities of the optical noise received in the MCL catch tank from the muzzle flash versus the narrowband optical signal levels generated from tiny emitters onboard a projectile after being launched in the MCL. Two narrowband optical signal emit...
متن کاملAlternative Space Vehicle Launch Systems
Over the last century chemical propellants have been the dominant fuel source for the aviation and aerospace industry, primarily because they are able to provide ample power for a limited cost. However, over the last decade as the price of chemical propellant continues to soar and their detrimental effect on our environment comes to light, there has been a surge to develop an alternative propul...
متن کاملResearch and Experiment on Electromagnetic Force Properties of LPMBLDCLM for Electromagnetic Launch
In order to improve the thrust characteristics of the moving-magnet type linear permanent magnet brushless DC motor (LPMBLDCM), the structural characteristics and magnetic field are analyzed. The influence rule of electrical parameters and structural parameters on the electromagnetic properties and thrust performance are researched by finite element analysis (FEA). The effect regularity of stru...
