Research Cost: Pending
Description
The phased array gravity drive, more commonly known as the impeller drive, is a Sub-Light/Faster-than Light propulsion system.
It Can be used for propulsion at sublight speeds, but also in hyperspace, but is highly dangerous when making contact with a gravity wave. Transforming it into a Warshawski sail largely removed this danger. 
Impeller wedge
The wedge was a pair of extremely powerful gravity bands located above and below the generating ship. Both bands were inclined such that the forward end, or "throat", was far deeper than the aft end, the "kilt". The wedge was capable of accelerating a vessel to near-light speed.
Due to the immense twisting and warping of space that occurred in the band, most known weapons can not penetrate an impeller wedge in either direction. The dorsal and ventral aspects were invulnerable to attack as long as the wedge was up. The flanks, forward, and aft aspects of the vessel were exposed.
In effect, the Impeller Wedge acts as an extremely strong Gravitic Shield with limited arcs of coverage.
