Paul March updates the Mach Effect Propulsion Work indicating some new challenges have been discovered and reviews the use of the effect for communication.
I [Paul March] found out over the Xmas break that our M-E device force output derivations as applied to our Excel spreadsheet design tools used to predict the M-E and QVF/MHD thrust performance, did NOT take into account the self-shielding E-field effect that any dielectric with a relative dielectric constant of greater than 1.00 subjects the expression of the E-field in that dielectric. In other words, if one is trying to use a high-k dielectric like the Y5U barium titanate blend, (e-r = ~5,000), used in the bulk of Woodward’s MLT devices to maximize the energy density and thus the M-E delta-mass signature, the net electric field expressed IN the dielectric acting on the ions used to calculate the bulk acceleration of the caps using the Lorentz force = vxB equation, will be reduced to a value equal to the externally applied E-field (Voltage / cap thickness d = V/m) divided by the relative dielectric constant. This implies that the naïve M-E force calculations for Y5U capacitors will be reduced by a factor of 5,000 when this self-shielding effect is taken into consideration. This would readily explain why Woodward’s naïvely predicted ~1,000 uN MLTs as calculated by the old M-E spreadsheet were instead producing less than 1.0 uN of thrust. It looks like we may have to separate variables in our M-E thrusters with one cap material used to optimize the production of M-E delta-mass signal, while using another material or approach to maximize the energy storing cap’s bulk acceleration used in the force rectification system.
Above is the newly recognized E-field cancellation effect. The E-field cancellation effect reduces the effect of changing the relative dielectric constant from a squared function to a linear function. It’s a bit of a hit in our optimization space, but there are lots of other parameters to push, so it’s no big deal.
However, when we try to use the Lorentz force to bulk accelerate the time varying delta mass cap structure as to do in the MLT (Mach Lorentz Thruster) to force rectify these delta mass fluctuations into a unidirectional force, this internal E-field cancellation phenomenon is a huge hit if we are using the same high-k dielectric to perform this vxB Lorentz force generation.
What this implies to me is that we have to use two different cap material in the MLT laid down in thin layers over each other, with one being optimized to store energy (High-k, high voltages and fast switching) while the other is chosen to maximize the generation of the Lorentz force. That’s not impossible, but it sure makes it a lot tougher to build.
