The test campaign consisted of a forward thrust phase and reverse thrust phase at less than 8×10−6 torr vacuum with power scans at 40, 60, and 80 W. The test campaign included a null thrust test effort to identify any mundane sources of impulsive thrust; however, none were identified. Thrust data from forward, reverse, and null suggested that the system was consistently performing with a thrust-to-power ratio of 1.2±0.1 mN/kW Итак, со всех сторон экранированный источник ЭМВ создает силу порядка 1 мН/кВт В вакууме. Для сравнения, давление солнечного света около Земли 0.01 мН/кв.м (мощность ок. ~ 1 кВт/кв.м), т.е. примерно в 100 раз меньше.
