他将其发表在NASA技术报告服务器上，标题是“螺旋引擎”。理论上来说它的工作原理是利用相对论性速度（即与真空中光速接近的速度）下质量变化的方式。
He 's posted it to the NASA Technical Reports Server under the heading " Helical Engine , " and , on paper , it works by exploiting the way mass can change at relativistic speeds - those close to the speed of light in a vacuum .

一些数值模拟结果表明在星风相互作用产生的弓激波的尾部，辐射物质的整体运动可以达到中等相对论性甚至极端相对论性速度。
Some hydrodynamic simulations show that in the tail of the bow shock produced by the wind interaction , the bulk motion of the particles can reach the mild-relativistic or ultrarelativistic velocities .
