NASA’s EmDrive engine test results are false and it doesn’t work; new study suggests

Scientists have been trying to develop powerful engines which can reduce the duration of space travel. To develop such technology, scientists from Eagleworks advanced-propulsion of NASA have been working on such engine which is known as the rocket propulsion engine, called EmDrive. As per the report, the engine will produce that much of power, it will take only 70 days to travel to Mars from Earth.

This powerful engine was originally developed by Roger Shawye, a British scientist in the year 2000. This engine will not require any fuel. The system will produce thrust by pushing microwaves out of the metal cone. It is expected that this engine will make the spaceflight cheaper.

Talking about some past reports, in 2016 NASA’s Johnson Space Center informed that NASA’s maverick team has tested the engine and also measured some thrust power. But during that time, no one was ready to believe on that. After that scientist from the Technical University at Dresden, Germany also conducted the test in a vacuum chamber which consisted various sensor and automated gizmos. Using that, the scientists tweaked the setting for different sources of thrust. They concluded that, when exposed to exposed to a magnetic field, the engine wasn’t able to produce thrust.  But when they reduced the level of microwaves by lowering the power, they got some thrust. At the space propulsion expo which was conducted recently, the researchers of the study informed that the EmDrive does not produce thrust. The thrust is produced by electromagnetic interaction.

During the study, the scientists detected that no matter what the direction was, there was thrust in the engine. The power for the thrust generates from the second sources, not from fuel, but from earth’s magnetism.

The newly published report stated that the recent experiments did not make use of a special shield of mu metals. These metals can protect the EmDrive from the interaction of aforementioned magnetic field. In 2016’s test, NASA didn’t use the mu metals. So, it can say that the test results from 2016 were false and they were lacking required magnetic fields.

Martin Tajmar, from TU Dresden, informed that they focused more to detect the sources of error which cause false trust indication. The researchers from German also used low power levels, which can cause actual indication. The new results of the test were introduced at the Space Propulsion Conference, 2018 which was held in Spain.
