From EM Drive
Description of Effort Thus Far
A truncated cone EM thruster.

- The truncated cone EM thruster was restrained by the torsional spring constant of the torsional pendulum used for measurement. The torsional spring constant effectively acts like a spring attached to a wall (the difference being that in the NASA Eagleworks test we have a torsional pendulum where the EM Drive performs a rotation instead of a rectilinear motion)
- The truncated cone EM thruster was initially at rest (prior to power input).
- A time-varying displacement (effectively due to a rotation around the torsional axis) was recorded and thus a force was calculated by NASA Eagleworks using the known constants of the system.
- We have verified this: we modeled NASA Eagleworks torsional pendulum, and furthermore analyzed the data using Fourier Transforms to obtain the Power Spectral Density and the Autocorrelation of the response.
