NationMaster - Encyclopedia: Bias drive

A concept from NASA's Breakthrough Propulsion Physics Program, the bias drive is a pitch drive that functions by altering the gravitational constant G in front of and behind the craft. One problem with this concept is that it would create a singularity in the field's gradient located inside the vehicle.

	Some examples include the Diametric drive, the Pitch drive, the Bias drive, the Alcubierre drive, the Disjunction drive, and the Differential sail.
	The pitch drive is a diametric drive which uses the principle of a disjoint field (as in the disjunction drive) to eliminate the need for the field to be generated on the spacecraft itself.
	The bias drive is a pitch drive that functions by altering the gravitational constant G in front of and behind the craft.
