Third Generation EmDrive
Roger Shawyer - July 2017
EmDrive Development Phases
3G EmDrive Theory
- First Generation. Original low thrust technology for in-orbit satellite applications. Reported to be operational in US and China.
- Second Generation. High thrust, low acceleration, superconducting technology. Space and Marine applications. Under development in UK and US.
- Third Generation. High thrust. High acceleration, superconducting technology. Theoretical work reported in US, China and UK. Aerospace applications including Launch Vehicles and Personal Air Vehicles.
High Q superconducting cavities are subject to large Doppler Shifts when accelerated.This can lead to the internal frequency being shifted outside the resonant bandwidth of the cavity over thetime constant of the cavity.
