Post-test data includes static and animated graphics produced during RF resonant cavity characterization using the COMSOL Multiphysics® software application. Test data gathered includes torsion pendulum displacement measurements which are used to calculate generated force, still imagery in the visible spectrum to document the physical configuration, still imagery in the infrared spectrum to characterize the thermal environment, and video imagery. Specifically, one test article contained internal physical modifications that were designed to produce thrust, while the other did not (with the latter being referred to as the "null" test article). Thrust was observed on both test articles, even though one of the test articles was designed with the expectation that it would not produce thrust.

Manual frequency control was required throughout the test.
In other words, the test article was tested on the bench, then moved to the chamber, then moved back as needed to resolve issues. Integration of the two test articles and their supporting equipment was performed in an iterative fashion between the test bench and the vacuum chamber. Approximately six days of test integration were required, followed by two days of test operations, during which, technical issues were discovered and resolved.
The torsion pendulum was designed, built, and operated by Eagleworks Laboratories at the NASA Johnson Space Center of Houston, Texas. The two test articles were designed by Cannae LLC of Doylestown, Pennsylvania. In addition, the test article was replaced by an RF load to verify that the force was not being generated by effects not associated with the test article. Several different test configurations were used, including two different test articles as well as a reversal of the test article orientation. Testing was performed on a low-thrust torsion pendulum that is capable of detecting force at a single-digit micronewton level, within a stainless steel vacuum chamber with the door closed but at ambient atmospheric pressure. Approximately 30-50 micro-Newtons of thrust were recorded from an electric propulsion test article consisting primarily of a radio frequency (RF) resonant cavity excited at approximately 935 megahertz. This paper will not address the physics of the quantum vacuum plasma thruster, but instead will describe the test integration, test operations, and the results obtained from the test campaign. Anomalous Thrust Production from an RF Test Device Measured on a Low-Thrust Torsion Pendulum This paper describes the eight-day August 2013 test campaign designed to investigate and demonstrate viability of using classical magnetoplasmadynamics to obtain a propulsive momentum transfer via the quantum vacuum virtual plasma.
