Experimental error! or a Reality? Amazing Facts about EmDrive

The EmDrive

Also known as "RF resonant cavity thruster" is new principle of electric propulsion for spacecraft has been introduced, which involves the use of microwave technology for the direct conversion of D.C power to thrust without the need for propellant.
The concept of EmDrive was basically introduced by Roger Shawyer, an aerospace engineer in 2001 and promotes the concept through his company "Satellite Propulsion Research LTD (SPRLTD)".

China and America started work on the EmDrive in 2010. After six years in December 2016 China claimed the successful operation of EmDrive engine succeeding America Again.
Dr. Chan Yu director of the CAST (China Academy of Space and technology) has confirmed the successful operation of EmDrive Technology on Dec 10, 2016. Moreover the CAST is planning for practical operation of EmDrive technology in space in September 2017.
A simplified description of the principles of the operation of EmDrive is given. The implications of the law of conservation of energy are examined for both static and dynamic operation of the device. 

Basic Principles

This technique involves the use of radiation pressure at microwave frequencies, in an engine which provides direct conversion from microwave energy to thrust, without the need for propellant.

Microwave energy is fed from a magnetron via a tuned feed to a closed tapered wave-guide, whose overall electrical length gives resonance at the operating frequency of the magnetron.
The group velocity of the electromagnetic wave at the end plate of the larger section is higher than the group velocity at the end plate of the smaller section.  Thus the radiation pressure at the larger end plate is higher than that at the smaller end plate. The resulting force difference is multiplied by the resonant assembly.

Pros and Cons:

There have been no cons of EmDrive till now but the Pros are as under.

• This successful operation of EmDrive engine will make a rapid change in Aerospace Technology in every aspect.

• The spacecraft using EmDrive Technology will be very light in weight and very quick than the rest due to zero consumption of any kind of Fuel.

• As EmDrive technology does not follow the 3rd law of Newton (action and reaction are equal in magnitude and opposite in direction), it will be cost efficient due to zero consumption of any kind of fuel.                                                                                                                                                                                                                                                                           If this Theory comes true, and the Chinese claim becomes truth, the spacecraft will be able to reach Mars in only ten days, will you believe this? Only Ten days. Now scientists will be able to reach other planets in very short time and we people will be able know truths about other planet’s life. I am really excited about this.
