Measurement of Impulsive Thrust from a Closed Radio-Frequency Cavity in Vacuum

Abstract

A vacuum test campaign evaluating the impulsive thrust performance of a tapered radio-frequency test article excited in the transverse magnitude 212 mode at 1937 MHz has been completed. 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. = vacuum permeability, N∕A 2 ρ ν = vacuum density, kg∕m 3

The Generation of Propulsion Force by the Quantum Energy: The “E-M Drive” Case

“…-Relating to the initial explicative hypothesis of H. White [1], it results-by Equation (4), that for the generating of resonant oscillations of the gammonic degenerate electrons in the quantum vacuum, are necessary coherent gamma-rays (specific to a graser emission) of (1), the previous proposed experiment may explain better the possibility to generate plasma filaments in air, with electrons density of 10 17 /cm 3 , by a high power microwave pulse overlapped in time and space with a high energy laser pulse, on a small localized region, [31], using a pulsed Nd:YAG laser beam (8 ns, 600 mJ, repetition rate 10 Hz) and a microwave pulse of maximum power of 400 MW, frequency of 10.1 GHz, and energy of 6.8 Joules. This possibility may be important also for the generation of ionic propulsion and levitation force in the Earth's atmosphere, by air ionizing and the acceleration or-respectivesimple repelling of the generated ions, by an adequate electrostatic E field.…”

“…The effect may be intensified by heating the metallic sections "f" with induction electric micro-currents of high frequency, (few hundred of MHz), according to Equation (1).…”

“…In a relative recent paper [1], were presented the NASA experimental results of a new type of propulsion in vacuum, obtained by a tapered radio-frequency (RF) cavity excited in the transverse magnetic (TM212) mode, at 1936.7 MHz which generated a unexplained thrust force F T at a thrust-to-power level of 1.2 -3 mN/kW (50.1 µN with 16.7 W) until 300 mN/kW (750 mN with 2.5 kW), in vacuum of less than 8 × 10…”

Stages of Quantomobile Development

“…It can vary and even become reverse, depending on the design of the resonator, placement of channels leading from the magnetron to the resonator, characteristics of the SHF field (McCulloch, 2014;White, 2017). This is calculated analytically with the use of equations (9)... (15).…”

Is the EM-Drive a Closed System?

“…According to Shawyer [1], the principle of operation of his revolutionary contraption is essentially based on the radiation pressure: in a few words, the alleged thrust would arise from the difference between the forces exerted upon the reflectors (the bases of the frustum). In spite of the fact that such a device, as long as it is considered as being a closed system, explicitly violates the conservation of momentum and Newton's well-known third law, it would appear, according to several tests to date carried out, that the EM-Drive can concretely deliver a certain thrust without a detectable exhaust [2]. As implicitly suggested in the foregoing sentence, the easiest way to solve the paradox may consist in demonstrating, first and foremost, that the device in question cannot be properly regarded as a closed system.…”
