- 2. DEPARTMENT OF MECHANICAL ENGINEEIRNG The EmDrive - A New concept in Spacecraft Propulsion
- 3. DEPARTMENT OF MECHANICAL ENGINEEIRNG INTRODUCTION • The EM Drive has been proposed as a revolutionary propellant less thruster using a resonating microwave cavity. • It works on the difference in radiation pressure due to the geometry of its tapered resonance cavity.
- 4. DEPARTMENT OF MECHANICAL ENGINEEIRNG OBJECTIVE AND SCOPE OBJECTIVE: • To remove the reaction mass in a Spacecraft Propulsion. • To minimize the pollution produced by petroleum fuels. • To reduce the total mass of a spacecraft. SCOPE: • This product will be capable to replace the fuel system in spacecraft. • This product can assure good quality and efficiency in working.

- 21. DEPARTMENT OF MECHANICAL ENGINEEIRNG CONCLUSION • The results of NASA's tests on the 'impossible' EM Drive have been leaked, and they reveal that the controversial propulsion system really does work, and is capable of generating impressive thrust in a vacuum, even after error measurements have been accounted for. • EM Drive works without any fuel or propellants at all. It works by simply bouncing microwave photons back and forth inside a cone-shaped closed metal cavity.
