Pre-research And Exploration Of Electromagnetic Drive System

At present,some new propulsion modes(normally called Anti-gravity)have emerged.Like as low frequency alternating electromagnetic propulsion system that the Searl effect and Hendo flying hoverboard represent,propulsion by electrostatic ion of asymmetric capacitor(Biefeld-Brown effect)that the lifter represents,and Hutchison effect combining above forms.But as far,there are still some technical bottlenecks existent or the principles unclear in the new propulsion methods,which restrict the large-scale deployment in practice.In the dissertation,researched on the new propulsion techniques,we focus on analyzing their inner ultimate principle.We built the compute mathematical models for them.By adjusting the sensitive parameter in the models,we can promote the competence of their output force.We attempt to solve the restricts and break up the technical bottlenecks in these propulsion systems.The dissertation based on nowadays worldwide relevant research results mainly shows us these works listed as follows:We analyzed the basic principle for low frequency anti-gravity method like as Hendo flying hoverboard.The low frequency anti-gravity device is normally composed of a low frequency AC coil and a metal reflector,where the low frequency electromagnetic wave produced by the electrified AC coil can also be substituted by a mechanical rotating disc on which some rare-earth permanent magnets are mounted.When the alternating magnetic field produced by the original AC coil is spread to the metal plate surface and reflected back by it,the phases of the original magnetic field waves shift.They lead to the molecule electric current’ s inversion between the original electromagnetic field waves and the reflected back waves.The inverse molecule current produces an electromagnetic force between the coil and the reflected metal.A mathematical model is established for the process for calculating the propelled force between them.Combining the numerical technique within Matlab software,we solved a hard-to-solve problem of complex integral in the mathematical model,and measured the numerical values of several empirical constants that exist in the result formula.The validity of the computing model confirmed by the subsequent experimental data achieved in test.The propelled force in static mode of asymmetric capacity has been derived.The relevant mathematical model has been established which is first proposed by us and accords the experimental data of the lifters.We interpreted the lift force source that exist in Biefeld-Brown effect.Through theoretical derivation,compute instance,testing and validating the results,the consist.ency between the theoretical model and the actual device is confirmed.Firstly,we analyzed the static thrust of equal surface density of charge distribution of asymmetric capacity.And then,we raised the scale-down-handing method for large-scale device by dimension analysis.A formula in special cases is derived from the original calculation result in the common case.Nextly,through estimating the lift competences of two typical asymmetric capacities in several special cases,the almost consistency between theoretical result and actual experimental data is verified.Lastly,by estimation and numerical computation method,we obtained the lift force value of a normal asymmetric capacity of one meter diameter.The work established the foundation for later thrust calculation of heavy-lift anti-gravity engine composed of series asymmetric capacities made of dynamic variable diameter channel.A calculation model for series asymmetric capacities lifter is constructed.By the model,we can work out the power export density and the terminal lift force.Through analyzing power export of variable diameter channel and some characteristics of plasma fluid,a valuable conclusion is obtained that the growth rate of thrust force is faster than itself body weight with increasing the number of the asymmetric capacities in series and lengthening the channel dimension.Details are illustrated that relevant to thrust like as ion flowrate,design principles for electrodes,inhaled turbulence,exit turbulence,plate distance,unit structure arrangement and other issues.After pointing out merits and demerits of various shapes designed for channels,we get the selecting method for different cases in experiments or in actual engineering applications.We chose several suitable inverters for series asymmetric capacities of dynamical system.We illustrated the atmospheric breakdown conditions in various structural forms in different environments and how to avoid them.Two ways for controlling flying attitude are provided:one is by high frequent magnetic field motivat ion to bestow the energy upon the plasma;The other is based on eight vector grating plates to control the attitude at six degrees of freedom in open space.At last,we calculated and proofread the wind resistance for testing style anti-gravity flying machine constructed by series asymmetric capacity of one meter diameter in earth near-surface atmospheric environment.
