BGM 시드마이어의 문명 : 비욘드 어스.In July 2014, the group reported on an evaluation of a RF resonant tapered cavity similar to Shawyer's EmDrive, with positive results.[14] Testing was performed on a low-thrust torsion pendulum that is capable of detecting force at a single-digit micronewton level, within a sealed stainless steel vacuum chamber, but at ambient atmospheric pressure, because the RF power amplifier used an electrolytic capacitor not capable of operating in hard vacuum.[14]
NASA's tests of the tapered RF cavity were conducted at very low power (98% less than Shawyer's 2002 experiment and 99.3% less than the Chinese 2010 experiment) but a net mean thrust over five runs was measured at 91.2 µN at 17 W of input power. A net peak thrust was recorded at 116 µN at the same power level.[14]
The experiment has been criticized for not having been performed in a vacuum, potentially allowing air currents to compromise results,[27] although tests were performed at about a hundred-millionth of normal atmospheric pressure.[28]
In the coming months, Eagleworks plans to upgrade their equipment to higher power levels, use vacuum-capable RF amplifiers with power ranges of up to 125 W, and design a new tapered cavity analytically determined to be in the 0.1 N/kW region. Then, the test article will be shipped to other laboratories for independent verification and validation of the technology, at Glenn Research Center, the Jet Propulsion Laboratory and the Johns Hopkins University Applied Physics Laboratory.[14]
