二维多翼翼型中拱线设计方法理论研究
|
摘要
基于势流理论和线性薄翼理论对二维多翼中拱线的设计问题开展理论研究。参考NACAa系列翼型设计思路,从均化翼型载荷的角度出发,建立了考虑多翼干扰效应的多翼翼型中拱线设计方法,将其应用到地效翼和栅格翼中,得到不同线性载荷参数和设计间距下的多翼中拱线解析式。该解析式物理意义明确,影响因素清晰,数学求解方便,对工程估算有重要参考价值。
Based on the potential flow theory and the linear thin fin theory, a design scheme about the mean lines of multi-wing in two-dimension was addressed. Referring to the design scheme about NACAa series and for the purpose of homogenizing the load distribution, a design scheme about the mean lines of multiwing was built in consideration of the interaction of multi-wing. The mean lines of WIG and multi-wing were designed respectively by the design scheme, and the mean lines were obtained at different linear load parameters and relative locations. The analytical expressions have good value for engineering evaluations due to clear physical meaning, obvious effect of the parameters and fast getting solutions.
