(wing)lift Explanation: "koppel" means here "couple=force (couple)" Lift is the force that directly opposes the weight of an airplane and holds the airplane in the air. Lift is generated by every part of the airplane, but most of the lift on a normal airliner is generated by the wings Wing design often proceeds by selecting a desirable wing lift distribution and then finding the geometry that achieves this distribution.

lift power Explanation: The power required for lift "Another fundamental shortcoming of the popular explanation is that it ignores the work that is done. Lift requires power (which is work per time). As will be seen later, an understanding of power is key to the understanding of many of the interesting phenomena of lift." Hope this helps Reference: http://www.aa.washington.edu/faculty/eberhardt/lift.htm Reference: http://www.vgtu.lt/english/editions/aviation/Nr_02.pdf |

pitch-up moment Explanation: I am an aeronautical engineer, but I have never heard of a 'stijgkoppel'. I would think that it denotes a change in the distribution of forces which causes a 'koppel' (=moment or torque) that makes the nose of the airplane pitch up. |
