Propulsion is provided by a rocket engine, rather than a propeller and rudder, which makes steering difficult.

推进器是由火箭发动机提供的，而不是螺旋桨和方向舵，这使得转向变得困难。

The test program will operate the permanent magnet propulsion motor up to full power (full torque and full load) in a test facility that simulates an actual U.S.Navy DDG-1000 engine room.

测试程序将在一个美海军仿真实际DDG - 1000引擎室的测试设施中操作永磁推进马达至全功率(全扭矩和全负载)。

The Death Star project concept falls in a practical sense at the first hurdle as nobody knows how to build a near light speed propulsion engine for it.

While the ship will not travel at warp speed, with an ion propulsion engine powered by a 1.5GW nuclear reactor, it can travel at a constant acceleration so that the ship can easily get to key points of interest in our solar system.

Conventional hybrids use mainly the gasoline engine for propulsion, drawing on the electric drive and batteries only occasionally to (impressively) improve gasoline efficiency.
