<p>An aircraft take-off runway, especially a ship's flight desk, is provided with a terminal ramp that curves upward to launch the aircraft in a semi-ballistic trajectory. The ramp is so configured as to have a varying contour or profile, in longitudinal section, at different regions across it, such that the path up the ramp of wheels on the center line of the aircraft is different from the path of wheels off the center line, e.g. outrigger wheels, whereby a desired pitching moment is imparted to the aircraft at launch.</p> |
