Abstract
Ski-jump take-off is a standard procedure for carrier-based aircrafts, and it is one of the key technologies for the generation of the combat effectiveness of the system. A 3D model carrier with a ski-jump deck is conceptually designed. The airflow field over the carrier is numerically simulated based on CFD. The longitudinal airstream line and velocity distribution, the velocity distributions in normal-wash area, tangential-wash area are derived and the influence of the ski-jump deck on the take-off zone is analyzed. The numerical simulation shows that the body-shedding vortex on both sides of the bow affects the engine intake at Take-off Point 1 and 2 and 3.
