Student Showcase: Electric Space Propulsion – An Exploration into Innovative Propellant Solutions Involving the Testing of an Electromagnetic Drive
Study Synopses: Since its birth, spaceflight has always been hindered by propellant constraints. Unfeasible amounts of fuel are required to cover the vast distances between stars and so modern spaceflight is confined to the solar system. A revolutionary electric propulsion system, according to Stansell, composed of a hollow asymmetric resonant cavity excited by microwaves, known as the EMDrive has been shown to produce a unidirectional acceleration although results have been inconclusive. This warrants further research.
According to Stansell a non-resonant EMDrive was constructed to act as a control, this design was then extended to create a new cavity which allowed for resonance at a frequency of 2450 MHz. The designs were tested in both the upright and inverted orientations to allow for EMDrive force separation from buoyant forces. The designs were tested on a millinewton resolution knife-edge fulcrum which was calibrated to accurately determine thrust magnitude.
Stansell revealed that due to thermal currents caused by the heating of the magnetron and cavity, each test experienced net upwards motion. However the resonant upright cavity moved upwards considerably more than the non-resonant control suggesting another force was at work pushing the cavity upwards. Additionally the resonant inverted test moved upwards considerably less than the control again indicating another force was counteracting the net upwards motion. This force varied in magnitude from 8.8825 millinewtons 11.8436 millinewtons.
In conclusion, according to Stansell, despite thermal current interference a replicable, anomalous thrust was produced. As the observed thrust is not yet attributable to any known physical phenomenon more research in vacuum is required.
