Centerline Thrust for Twin Engine Aircraft

This paper compares the controllability and performance of the conventional twin and centerline thrust (CLT) twin after an engine failure during take-off. The CLT concept offers, for the first time, controllability down to stall speed with one engine inoperative. In addition, it reduces by 50% the total engine out take-off distance over a 50 ft obstacle. These advantages are significant to all users of twin engine airplanes, and they are almost essential for the safety of pilots flying relatively low powered twins out of short fields.
