Forces, Power, Frequency and Dimensions

The current best estimates for the parameters of various test articles run by public and private research labs (NASA Eagleworks, SPR Ltd., and NWPU) is here, along with the reported forces. Note that complete dimensions are not known in most cases, and some had to be determined via indirect methods (e.g., estimation from photographs). See Building for details on drives built by do-it-yourselfers.

Credit to Dr. Rodal and others for the great effort in compiling these. Please note some caveats for this data, at that link.

  1. Forum post by @phaseshift - Design Factor and smallDiameter were revised based on an (assumed) typo in the published source
  2. Forum post by @Rodal - Included here because Prof. Woodward's device is also a propellant-less concept, and because Paul March (NASA) maintains that Prof. Woodward's Mach Effect theory might also be, in his opinion, an explanation for thrust for the EM Drive.
