The running distance of aircraft during takeoff is too long for the airfield in plateau regions,thus we introduced chaotic genetic optimization algorithm in the optimum design of ski-jump ramp take-off runway.

Based on the takeoff safety criterion,a ski-jump model was developed to predict a land-based ski-jump takeoff performance for a fixed-wing aircraft.

The mathematical model of aircraft ski-jump takeoff with the influence of micro-downburst is established in the paper,and the influence of micro-downburst on aircraft ski-jump takeoff was analyzed using numerical method.

A dynamics model of ski-jump takeoff on land was established.

The optimal choice of parameters for ski-jump take-off of naval aircrafts;

According to the flight-dynamics theory,a mathematical model of aircraft ramp ski-jump take-off is established.

The numerical simulation of flow around the warship during ramp ski-jump take-off;
