Mike McCulloch's MiHsC Theory

2015-05-20T21:03:40Z

MazonDel: Added some light information on Mike McCulloch's theory.

Theory

2015-05-20T20:59:17Z

MazonDel: /* Proponent Theories */ Providing Mike McCulloch with his page.

This page will outline some candidate theories of operation (or non-operation).

== Debunking Theories ==
*These theories should be explained, then debunked with the simplest explanation, with a link to a dedicated page to show the work or work in progress that backs up that explanation.

=== Experimental error ===
* It's all a hoax/conspiracy
* Simple measuring error
* Thermal effects
* Mechanical vibration
* Magnetic effects with environment

These are discussed in more detail at [[Possible Error Sources]].

=== Proponent Theories ===
* Guido Fetta's, Cannae Drive creator's Theory
* Roger Shawyer's, EM Drive creator's theory
* Quantum foam MHD
* Harold White's Quantum vacuum plasma thruster (QVP thruster)
* Harold White's Warp effects
* [[Evanescent waves]]<ref>[http://forum.nasaspaceflight.com/index.php?topic=36313.msg1330521#msg1330521 2/2/15 post by @aero modeled evanescent waves] using [http://ab-initio.mit.edu/wiki/index.php/Meep MEEP]. Conclusion was that, due to rapid dropoff at the frustum surface, these were of insufficient magnitude to explain the thrust.</ref>

Generic EM Drive Information

2015-05-20T20:22:31Z

MazonDel: /* Mode Shape */ Added info about the dielectric.

This is a location for assorted information concerning EM Drives. Likely applies to all current experimental efforts.

== Conservation of Energy Violation ==

Doctor White has proposed that the EM Drive is capable of producing constant thrust at a constant power output. User frobnicat has shown (in the following text and image) that if this were to be true, then the EM Drive could be utilized as a source of unlimited energy. <ref>[http://forum.nasaspaceflight.com/index.php?topic=37438.msg1369806#msg1369806 frobnicat on using the EM Drive for unlimited energy.]</ref> This of course constitutes a violation of [http://en.wikipedia.org/wiki/Conservation_of_energy Conservation of Energy.]

"As often remarked : for any propellantless device yielding "given constant thrust for given constant power" (ie. a definite thrust/power ratio) there is a velocity relative to a power feedback loop system above which net power surplus can be generated (indefinitely, wear apart).
This velocity is simply the inverse of the thrust/power ratio : V (m/s) = power (W) / thrust (N)." -frobnicat <ref>[http://forum.nasaspaceflight.com/index.php?topic=37438.msg1370818#msg1370818 frobnicat explains constant thrust/power feedback loop]</ref>

<img src="http://forum.nasaspaceflight.com/index.php?action=dlattach;topic=29276.0;attach=619549;image" style="width:20%">

On the assumption that the results provided by the various experimenting groups are valid, then one of the following two options as provided by user deltamass<ref>[http://forum.nasaspaceflight.com/index.php?topic=36313.msg1370943#msg1370943 deltamass on the Energy Paradox.]</ref> and clarified by user frobnicat <ref>[http://forum.nasaspaceflight.com/index.php?topic=36313.msg1371907#msg1371907 frobnicat on apparent/non-apparent CoE breakage.]</ref> must be true. The options are as follows:

'''Option 1''': Energy is conserved, but there is a preferred rest frame. In essence, the drive has a maximum change in velocity (a decreasing acceleration curve) that it can impart irrespective of its starting velocity. The idea of a preferred rest frame is at odds with [http://en.wikipedia.org/wiki/General_relativity general relativity].

'''Option 2''': An '''apparent''' breach of conservation of energy is possible, where the mechanism by which conservation of energy is maintained is as yet unknown. An example of a possible solution to this problem is that the drive could in some way be emitting [http://en.wikipedia.org/wiki/Tachyon tachyons.]<ref>[http://forum.nasaspaceflight.com/index.php?topic=36313.msg1371907#msg1371907 frobnicat on tachyons.]</ref>

Tachyons are fictional particles that can travel faster than the speed of light. Sending signals faster than light, leads to violations of causality, see: [http://en.wikipedia.org/wiki/Tachyonic_antitelephone Tachyonic Antitelephone.]

Since option 1 leads to a violation of general relativity and option 2 leads to a violation of causality, one concludes that, with constant input power supplied to the EM Drive, the acceleration cannot be constant. As remarked by WarpTech the acceleration must decrease with increasing velocity, as per Newton's 2nd law:<ref>[http://forum.nasaspaceflight.com/index.php?topic=36313.msg1370683#msg1370683 WarpTech on decreasing acceleration with increasing velocity.]</ref>

Acceleration = Thrust / Mass = Power / (Mass*Velocity)

So, for constant input power to the EM Drive (and constant vehicle mass), the vehicle's acceleration must decrease in inverse proportion to the vehicle's velocity. To achieve constant acceleration, increasing power must be supplied to the EM Drive, in proportion to the increasing velocity.

== Mode Shape ==

See calculations pertaining to the relationship between thrust and mode shape at [http://forum.nasaspaceflight.com/index.php?topic=36313.msg1317866#msg1317866 Notsosureofit's post] and [http://forum.nasaspaceflight.com/index.php?topic=36313.msg1318217#msg1318217 Rodal's response.]

An EM Drive is a cavity resonator that uses the Quality Factor Q to achieve greater response. There is definitely a peak resonant frequency to achieve the highest Q, though besides Q and frequency, mode shape must also be considered. The shape of the electric and magnetic fields inside the cavity at a given frequency.<ref>[http://forum.nasaspaceflight.com/index.php?topic=36313.msg1319407#msg1319407 Rodal on frequency, Q, and mode shape.]</ref>

The mode-shape to frequency relation is very sensitive to the exact [[Experimental Results|dimensions of the cavity]]. <ref>[http://forum.nasaspaceflight.com/index.php?topic=36313.msg1319117#msg1319117 Rodal's post on geometric relations to mode shape.]</ref> However, a dielectric can be used to help force a selected mode shape upon the cavity.<ref>[http://forum.nasaspaceflight.com/index.php?topic=36313.msg1319655#msg1319655 Rodal on the dielectric's contribution to mode shape.]</ref>

Generic EM Drive Information

2015-05-20T19:32:29Z

MazonDel: Added information about how frequency, Q, and mode shape bundle together.

This is a location for assorted information concerning EM Drives. Likely applies to all current experimental efforts.

== Conservation of Energy Violation ==

Doctor White has proposed that the EM Drive is capable of producing constant thrust at a constant power output. User frobnicat has shown (in the following text and image) that if this were to be true, then the EM Drive could be utilized as a source of unlimited energy. <ref>[http://forum.nasaspaceflight.com/index.php?topic=37438.msg1369806#msg1369806 frobnicat on using the EM Drive for unlimited energy.]</ref> This of course constitutes a violation of [http://en.wikipedia.org/wiki/Conservation_of_energy Conservation of Energy.]

"As often remarked : for any propellantless device yielding "given constant thrust for given constant power" (ie. a definite thrust/power ratio) there is a velocity relative to a power feedback loop system above which net power surplus can be generated (indefinitely, wear apart).
This velocity is simply the inverse of the thrust/power ratio : V (m/s) = power (W) / thrust (N)." -frobnicat <ref>[http://forum.nasaspaceflight.com/index.php?topic=37438.msg1370818#msg1370818 frobnicat explains constant thrust/power feedback loop]</ref>

On the assumption that the results provided by the various experimenting groups are valid, then one of the following two options as provided by user deltamass<ref>[http://forum.nasaspaceflight.com/index.php?topic=36313.msg1370943#msg1370943 deltamass on the Energy Paradox.]</ref> and clarified by user frobnicat <ref>[http://forum.nasaspaceflight.com/index.php?topic=36313.msg1371907#msg1371907 frobnicat on apparent/non-apparent CoE breakage.]</ref> must be true. The options are as follows:

'''Option 1''': Energy is conserved, but there is a preferred rest frame. In essence, the drive has a maximum change in velocity (a decreasing acceleration curve) that it can impart irrespective of its starting velocity. The idea of a preferred rest frame is at odds with [http://en.wikipedia.org/wiki/General_relativity general relativity].

'''Option 2''': An '''apparent''' breach of conservation of energy is possible, where the mechanism by which conservation of energy is maintained is as yet unknown. An example of a possible solution to this problem is that the drive could in some way be emitting [http://en.wikipedia.org/wiki/Tachyon tachyons.]<ref>[http://forum.nasaspaceflight.com/index.php?topic=36313.msg1371907#msg1371907 frobnicat on tachyons.]</ref>

Tachyons are fictional particles that can travel faster than the speed of light. Sending signals faster than light, leads to violations of causality, see: [http://en.wikipedia.org/wiki/Tachyonic_antitelephone Tachyonic Antitelephone.]

Since option 1 leads to a violation of general relativity and option 2 leads to a violation of causality, one concludes that, with constant input power supplied to the EM Drive, the acceleration cannot be constant. As remarked by WarpTech the acceleration must decrease with increasing velocity, as per Newton's 2nd law:<ref>[http://forum.nasaspaceflight.com/index.php?topic=36313.msg1370683#msg1370683 WarpTech on decreasing acceleration with increasing velocity.]</ref>

Acceleration = Thrust / Mass = Power / (Mass*Velocity)

So, for constant input power to the EM Drive (and constant vehicle mass), the vehicle's acceleration must decrease in inverse proportion to the vehicle's velocity. To achieve constant acceleration, increasing power must be supplied to the EM Drive, in proportion to the increasing velocity.

Thermal Effects - Drive

MazonDel: Changed the content 'insert image...' to actually displaying the image.

One common theorized source of the anomalous thrust is that thermal effects endemic to the structure or components of the activated drive may alter the center of mass or otherwise influence the thrust reading.

Generic EM Drive Information

2015-05-14T20:38:35Z

MazonDel: /* Mode Shape */ Added more info.

This is a location for assorted information concerning EM Drives. Likely applies to all current experimental efforts.

== Velocity ==

At constant input power, the thrust, and therefore the acceleration, must decrease with time, to ensure that the spacecraft's (change in) velocity never exceeds 2*Power/Thrust.<ref>[http://forum.nasaspaceflight.com/index.php?topic=36313.msg1314503#msg1314503 Rodal's post concerning the energy/thrust constraint.]</ref> Effectively, White proposes that the maximum velocity possibly achievable for these EM Drives is 2*PowerInput/ThrustForce. This energy constraint is known even from Sutton's textbook on Elements of Rocket Propulsion (equation 19-1 Rocket propulsion elements 7th edition- Sutton).

The higher the ThrustForce/InputPower, the lower the maximum velocity of an EM Drive: MAXIMUM VELOCITY OF EM DRIVE = 2 /(thrustForce/PowerInput)
#(Brady TE mode) ThrustForce/power: 0.00002131 Newton/Watt --> MaximumVelocity = 2/0.00002131 m/s = 93853 m/s = 93.85 km/s
#(Prof. Juan Yang et.al. China) ThrustForce/power: 0.000290 Newton/Watt --> MaximumVelocity = 2/0.000290 m/s = 6897 m/s = 6.90 km/s
#(Cannae Superconducting) ThrustForce/power: 0.0009524 Newton/Watt --> MaximumVelocity = 2/0.0009524 m/s = 2100 m/s = 2.10 km/s

The maximum velocity of the EM Drive is inversely proportional to Q: <ref>[http://forum.nasaspaceflight.com/index.php?topic=36313.msg1314529#msg1314529 Rodal's post concerning velocity and Q.]</ref> Therefor the higher the Q, the lower the maximum velocity.
#MAXIMUM VELOCITY OF EM DRIVE = 2 /(thrustForce/PowerInput)
#MAXIMUM VELOCITY OF EM DRIVE ~ (2 /(Q*otherParameters))

== Kinetic Energy ==
The frame-of-reference kinetic energy issues (for non-relativistic spacecraft speeds) are eliminated by the definition of constant acceleration as acceleration=(delta velocity)/(delta time) so that (delta velocity)=acceleration*(delta time).<ref>[http://forum.nasaspaceflight.com/index.php?topic=36313.msg1315154#msg1315154 Rodal's Post on Changing Kinetic Energy.]</ref> Since from Newton's 2nd law, acceleration=ThrustForce/Mass, the change in velocity is uniquely defined in terms of: ThrustForce, total Mass of the spacecraft and DeltaTime (regardless of velocity-frame-of-reference) directly as (delta velocity)=(ThrustForce/Mass)*(delta time). The intrinsic definition of the change in KineticEnergy of the spacecraft under constant acceleration:
*deltaKineticEnergy = (1/2)*Mass*((delta velocity)^2)
*deltaKineticEnergy = (1/2)*Mass*([(ThrustForce/Mass)*(delta time) ]^2)

For the EM Drive to make any sense as a '''closed system''' it implies having memory of its time-history in order to never exceed the critical velocity at which (for constant InputPower throughout the time period (delta time)):

*InputPower*(delta time) = (1/2)*Mass*[(ThrustForce/Mass)*(delta time) ]^2 <ref>Consistent with equation 19-1: Rocket Propulsion Elements 7th edition- Sutton</ref>

If the EM drive conserves momentum by interacting with the QuantumVacuum for example, we have an '''open system''' where momentum will be flowing in or out of the cavity, and therefore the open system should be taken into account in the conservation of kinetic energy (which we have not done) in order to arrive at a satisfactory answer.

== Mode Shape ==

See calculations pertaining to the relationship between thrust and mode shape at [http://forum.nasaspaceflight.com/index.php?topic=36313.msg1317866#msg1317866 Notsosureofit's post] and [http://forum.nasaspaceflight.com/index.php?topic=36313.msg1318217#msg1318217 Rodal's response.]

The mode-shape to frequency relation is very sensitive to the exact geometrical dimensions of the cavity. <ref>[http://forum.nasaspaceflight.com/index.php?topic=36313.msg1319117#msg1319117 Rodal's post on geometric relations to mode shape.]</ref>

MazonDel: Adding a page to the Main page detailing Generic EM Drive Information.

<strong>Welcome to the EM Drive wiki.</strong>

This site is a repository of the current information available for the [http://www.nasaspaceflight.com/2015/04/evaluating-nasas-futuristic-em-drive/ EM Drive project] currently underway at NASA Eagleworks. The goal is to present all the background documentation in one place, so people following the forum threads can quickly get up to speed on what has been previously discussed.

''Please note that this is an unmoderated, community-run site that discusses a rather controversial topic.'' As such, anyone is free to write whatever she/he wants regarding her/his own work or posts regarding the EM Drive. However, other people's work (whether they be posts in the NasaSpaceFlight.com forums or elsewhere) should only be linked or quoted verbatim (but never paraphrased). This will prevent a repeat of the problems witnessed in the past due to the false, misleading reports in the media about the EM Drive research done by NASA Eagleworks.

== Contents ==

[[Frequently Asked Questions]] - A good place to start.

[[Possible Error Sources]] - Attempts to explain anomalous thrust via experimental error or 'conventional' means.

[[Building]] - A few people are trying to build their own.

[[Experimental Results]] - Experimental data provided by currently investigating groups.

[[Theory]] - While there's no consensus on any of this, here are various attempts to support (and debunk) it.

[[Generic EM Drive Information]] - A location to compile generic/interesting information (calculations, factoids, etc).

[[Useful Documentation]] - A list of all documentation referenced in the thread.

== NasaSpaceFlight.com Links ==

* [http://forum.nasaspaceflight.com/index.php?topic=29276.0 NASASpaceFlight.com EM Drive Developments - Thread 1] - Original thread on NSF.
* [http://forum.nasaspaceflight.com/index.php?topic=36313.0 NASASpaceFlight.com EM Drive Developments - Thread 2] - detailed analysis of the experimental setup and possible theories of operation. This is the primary thread providing information to this wiki.
* [http://forum.nasaspaceflight.com/index.php?topic=37438.0 NASASpaceFlight.com Feature Article Discussion] - less-technical discussion of the above blog post.

Evanescent waves

2015-05-14T18:28:44Z

MazonDel: Added a page explaining the status of the evanescent wave theory.

As proposed by Aero on the NSF forums, the possibility that the thrust is occurring as a result of the generation/leakage of evanescent waves.

== Status ==

No longer considered a viable source of thrust.

== Evidence ==

Initial calculations by Aero were showing an efficiency rating 2-3 times that of a perfect photon drive, which is beneath the observed ratings of Q-thruster test articles.<ref>[http://forum.nasaspaceflight.com/index.php?topic=36313.msg1313876#msg1313876 Initial calculations by aero.]</ref>

Utilizing [http://ab-initio.mit.edu/wiki/index.php/Meep MEEP], the conclusion was that due to rapid dropoff at the frustum surface, evanescent waves were of insufficient magnitude to explain the observed thrust.<ref>[http://forum.nasaspaceflight.com/index.php?topic=36313.msg1330521#msg1330521 this post by @aero on modeled evanescent waves]</ref>

== References ==

Theory

2015-05-14T18:16:28Z

MazonDel: Creating a page for Evanescent Waves.

This page will outline some candidate theories of operation (or non-operation).

== Debunking Theories ==
*These theories should be explained, then debunked with the simplest explanation, with a link to a dedicated page to show the work or work in progress that backs up that explanation.

=== Experimental error ===
* It's all a hoax/conspiracy
* Simple measuring error
* Thermal effects
* Mechanical vibration
* Magnetic effects with environment

These are discussed in more detail at [[Possible Error Sources]].

=== Proponent Theories ===
* Guido Fetta's, Cannae Drive creator's Theory
* Roger Shawyer's, EM Drive creator's theory
* Quantum foam MHD
* Harold White's Quantum vacuum plasma thruster (QVP thruster)
* Conservation of momentum breaking theories
** Mike McCulloch's MiHsC<ref>[http://physicsfromtheedge.blogspot.co.uk/2015/05/mihsc-vs-29-anomalies.html 3/5/15 post by Mike McCulloch, MiHsC vs 29 anomalies]</ref> - this deserves an entire subsection - see http://physicsfromtheedge.blogspot.co.uk/
* Harold White's Warp effects
* [[Evanescent waves]]<ref>[http://forum.nasaspaceflight.com/index.php?topic=36313.msg1330521#msg1330521 2/2/15 post by @aero modeled evanescent waves] using [http://ab-initio.mit.edu/wiki/index.php/Meep MEEP]. Conclusion was that, due to rapid dropoff at the frustum surface, these were of insufficient magnitude to explain the thrust.</ref>
* Transfer of linear momentum from the Quantum Vacuum to magnetoelectric and chiral molecules <ref>http://forum.nasaspaceflight.com/index.php?topic=36313.msg1330846#msg1330846 and http://forum.nasaspaceflight.com/index.php?topic=36313.msg1333392#msg1333392 </ref>

NASA Eagleworks

2015-05-14T14:58:53Z

MazonDel: Created NASA Eagleworks Page.

== Description of Effort Thus Far ==
A truncated cone EM thruster.

== Status ==

In Progress.

== Information ==

Items 1-4 Located at [http://forum.nasaspaceflight.com/index.php?topic=36313.msg1310242#msg1310242 this post.]
# The truncated cone EM thruster was restrained by the torsional spring constant of the torsional pendulum used for measurement. The torsional spring constant effectively acts like a spring attached to a wall (the difference being that in the NASA Eagleworks test we have a torsional pendulum where the EM Drive performs a rotation instead of a rectilinear motion)
# The truncated cone EM thruster was initially at rest (prior to power input).
# A time-varying displacement (effectively due to a rotation around the torsional axis) was recorded and thus a force was calculated by NASA Eagleworks using the known constants of the system.
# We have verified this: we modeled NASA Eagleworks torsional pendulum, and furthermore analyzed the data using Fourier Transforms to obtain the Power Spectral Density and the Autocorrelation of the response.

== References ==

Experimental Results

MazonDel: Adding in a section for the NASA Eagleworks team.

The results from NASA, SPR Ltd., NWPU, etc. will be referenced here.

Frequently Asked Questions

2015-05-14T14:32:26Z

MazonDel: Added a link to an image (uncertain how to add the image to the page).

Still working on it.

In the meantime, [http://www.reddit.com/r/Futurology/comments/34cq1b/the_facts_as_we_currently_know_them_about_the/ this Reddit page] has a pretty good summary.

-EDIT- If I may: Fantastic idea! Looking forward to a packed wiki :D Rgrds PaulF

<strong>Welcome to the EM Drive wiki.</strong>

This site is a repository of the current information available for the [http://www.nasaspaceflight.com/2015/04/evaluating-nasas-futuristic-em-drive/ EM Drive project] currently underway at NASA Eagleworks. The goal is to present all the background documentation in one place, so people following the forum threads can quickly get up to speed on what has been previously discussed.

At present, the primary thread providing information to this wiki can be accessed at [http://forum.nasaspaceflight.com/index.php?topic=36313.0 this location.]

[[Frequently Asked Questions]] - A good place to start.

[[Possible Error Sources]] - Attempts to explain anomalous thrust via experimental error or 'conventional' means.

[[Building]] - A few people are trying to build their own.

[[Experimental Results]] - Experimental data provided by currently investigating groups.

[[Theory]] - While there's no consensus on any of this, here are various attempts to support (and debunk) it.

[[Useful Documentation]] - A list of all documentation referenced in the thread.
