| 摘 要： | 滑跃起飞是舰载机在航母上常见的 1种起飞方式,是舰载机战斗力生成的关键技术之一。概念设计带滑跃甲板的航母 3D模型,基于计算流体力学(Computational Fluid Dynamic,CFD)技术,对航母空气流场进行数值模拟,得出航母滑跃甲板流场纵向气流流线、法洗区速度分布情况、切洗区速度分布情况、航母流场纵向速度分布情况等,分析滑跃甲板对起飞区流场的影响。数值模拟得出以下结论:舰艏滑跃甲板的两侧脱体涡对 1、2和 3号起飞位的舰载机发动机进气量有影响。

| Abstract: | Ski-jump take-off is a standard procedure for carrier-based aircrafts, and it is one of the key technologies for thegeneration 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 distri.bution, the velocity distributions in normal-wash area, tangential-wash area are derived and the influence of the ski-jumpdeck on the take-off zone is analyzed. The numerical simulation shows that the body-shedding vortex on both sides of thebow affects the engine intake at Take-off Point 1 and 2 and 3. |
