某型地效翼船翼型选择分析

Airfoil Selection Analysis of a Wing In Ground Wing Ship

地效翼船(WIG)是一种融合了航空技术与船舶技术的新型高性能船舶,而机翼是产生地面效应和提供升力的主要部件,翼型的优劣直接影响地效翼船的飞行性能。根据某型地效翼船的气动布局特点建立分析模型,采用面元法对2种翼型的气动特性进行计算。对比2种翼型的特性曲线,结果表明,在同一条件下,2#翼型具有更大的升力,地效翼船的起降性能更优越,因此该型地效翼船的机翼更适合采用2#翼型。

The wing in ground(WIG)wing ship is a new type of high performance ship which combines aviation technology and ship technology,and the wing is the main component to produce ground effect and provide lift.The quality of airfoil directly affects the flight performance of the WIG wing ship.According to the aerodynamic layout characteristics of a certain ground effect airfoil,the analysis model is established,and the surface element method is used to calculate the aerodynamic characteristics of the two airfoils.The difference of the characteristic curves of the two airfoils shows that the 2#airfoil has a larger lift,and the take-off and landing performance of the WIG wing ship is better under the same conditions,so the 2#airfoil is more suitable for the wing of the airfoil.
