Phase Displacement
Space DriveInterstellar Propulsion
by Moacir L. Ferreira Jr.May 03, 2011
• In expelling-mass propulsion, most of the energy goes away with propellants. Δv=ve×ln(mi/mf)
• There is a possibility of creating propulsion without expelling mass that doesn’t infringe Newton's third law (action-reaction)
• Even though electromagnetic waves have no mass, they still carry momentum. Probably, due to interaction with space, which is permeated by electric/magnetic fields.
• Having two emitters A B, phased 0° 90°, and quarter-wave spaced (nλ+¼λ)
• Starting from A, wave will reach B in-phase 0° (repulsion)
• Starting from B, wave will reach A in-contra-phase 180° (attraction)
• Waves' momentum pulls A, pushes B, creating thrust force, A towards B.
• Action-reaction is expected between space and waves, and between waves and emitters. Angular momentum probably is not conserved due to asymmetry (¼λ), converting into net thrust force.
• Directional antennas, facing each other, can be
used to concentrate radiation. In this case, higher RF voltage is needed due to higher impedance between antennas.
• Even with heavy EM losses, it is expected to be comparatively more energy-efficient than expelling-mass propulsion.
To think:(0° 90°)(nλ+¼λ) → (attraction) (repulsion )(0° 90°)(nλ+¾λ) → (repulsion ) (attraction)(0° 0°)(nλ ) → (repulsion ) (repulsion )(0° 0°)(nλ+½λ) → (attraction) (attraction) …(0° 60°)(½λ+ λ)⅙ → (repulsion ) (attraction)
• Alternatively, having an array of dipoles, spaced-apart (½λ+ ⅙λ), and feed by six phases, running as a multiphasic linear AC motor.
• Comparatively, it will consume more energy than the two directional antennas. However, it can perform more interaction with cosmic dusts and gases.
Fusion Energy Source
• Fusion fuels: He-3, Li-6/7, deuterium, and B-11; available on moons, planets and asteroids.
• Multi-megavolt electrostatic generator (low
charge/mass ratio). Neutralization at outputs (low power consumption).
• Fusion energy conversion directly into electricity by multistage ion collectors; and subsequently recycling byproducts.
Fusion Energy Source
Conclusion:
• All that is to reduce drastically dependence on propellants and also on rare fuels (uranium, plutonium, tritium, antimatter), making the interstellar travels technically feasible and economically affordable.
