Thrust systems for passenger aircraft provide at least one flight engine and a taxi engine wherein all flight engines together provide, in total, a takeoff thrust arranged in a takeoff thrust direction and the taxi engine provides a taxi thrust which does not exceed 15% of the takeoff thrust and is directed substantially the same as the takeoff thrust direction. The taxi thrust is thereby sufficient to taxi the aircraft along a taxi path. In a system embodiment, the taxi thrust does not exceed 7.5% of the flight thrust. In another system embodiment, the ...
I claim: 1. A thrust system for an aircraft having a tail portion, comprising:one or more flight engines positioned on said aircraft, each of said flight engines having a take-off thrust corresponding to a maximum rated thrust, a lesser cruise thrust and an idle thrust which is equal or less than the cruise thrust, all flight engines together providing a combined rated thrust sufficient for takeoff said flight engines arranged to direct said takeoff thrust in a takeoff thrust direction; anda taxi engine located in the fuselage in said tail portion, the t...
