'Impossible' Space Engine May Actually Work, NASA Test Suggests
By Mike Wall, Senior Writer | August 01, 2014 03:59pm ET
It's really starting to look as if an "impossible" space propulsion technology actually works.
Researchers at NASA's Johnson Space Center in Houston have found that a microwave thruster system that requires no propellant does indeed generate a small amount of thrust, Wired UK reported Thursday (July 31). If the technology pans out, it could make spaceflight far cheaper and speedier, potentially opening up much of the cosmos to exploration, advocates say.
"Test results indicate that the RF [radio frequency] resonant cavity thruster design, which is unique as an electric propulsion device, is producing a force that is not attributable to any classical electromagnetic phenomenon and, therefore, is potentially demonstrating an interaction with the quantum vacuum virtual plasma," the NASA team wrote in their study, which they presented Wednesday (July 30) at the 50th Joint Propulsion Conference in Cleveland.
The roots of the propulsion system tested by the NASA team trace back to a British researcher named Roger Shawyer, who claims that his "EmDrive" generates thrust by rocketing microwaves around in a chamber. There is no need for propellant, as solar power can be used to produce the microwaves.
Shawyer says that his company, Satellite Propulsion Research Ltd., has successfully tested experimental versions of the thruster. But many scientists have dismissed or downplayed such claims, saying the propulsion system violates the law of conservation of momentum, Wired UK reported.
但是许多科学家无视甚至贬低Shawyer的这一装置，说他的推进系统违反了【现有】的物理法则，Wired UK网站报告道
然而，在2012年，一队中国的研究者建立了他们自己版本的系统发现它确实可以工作，产生一个可以足够推进卫星的力量。
然后，一个名为Guido Fetta的美国科学家也建设了自己的装置，命名为：Cannae Drive（以坎尼命名，意大利古罗马著名战场） 并说服了NASA团队--其中包括曲率引擎的研究者Sonny White让他们试一下，就这样他们在2013年研究了这个课题8天
In 2012, however, a team of Chinese researchers built their own version of the system and found that it does indeed work, generating enough thrust to potentially power a satellite. Then, an American scientist named Guido Fetta constructed his own device, which he calls the "Cannae Drive," and convinced the NASA team — which included warp drive researcher Sonny White — to try it out, which they did over the course of eight days in August 2013.
The NASA scientists determined that the Cannae Drive produces 30 to 50 micronewtons of thrust — less than 0.1 percent of that measured by the Chinese team, Wired UK noted, but nevertheless suggesting that the technology works.
NASA科学家们测定的坎尼引擎制造了30-50的微牛推力--少于中国团队测量的0.1%。Wired UK报告道。但是毫无疑问，这个技术能用
The thruster may work by somehow harnessing the subatomic particles that continuously pop into and out of existence, the NASA researchers suggest. The results and the technology are promising enough to warrant further study, they wrote in the study.
NASA研究者表示：引擎或许是以这样的方式工作：通过控制一种可以即行出现即行消失的未知粒子。
他们在研究中写道，鉴于此结果及科技，已经保证准备好对此做更长期的研究
"Future test plans include independent verification and validation at other test facilities," the researchers wrote.
研究者写到“未来的测试打算，包括在其他的实验设施中进行独立、重复的核实确认” |
