摘要
随着化石能源的日益枯竭和人们对环境污染问题的日益关注,相对于喷气式推进装置,高推进效率、低燃油消耗的螺旋桨推进装置受到越来越多的重视,迎来了新的发展机遇。然而,提高推进效率和解决噪声污染问题一直是螺旋桨飞机发展的巨大挑战。本文以航空螺旋桨为研究对象,就其运行中的空气动力学和气动噪声问题进行探讨。文章首先概述了螺旋桨研究的历史及发展;然后从理论分析、数值计算、风洞试验三类研究手段着手,对螺旋桨常用翼型、总体气动特性等关键空气动力学问题的研究现状及取得的关键进展进行了综述和讨论;随后介绍了国内外在螺旋桨飞机气动噪声领域所取得的研究进展,主要包括螺旋桨噪声的产生机理、降噪主要方法、噪声预测方法等;最后对航空螺旋桨气动、噪声与优化设计的未来研究提出了一些展望。
With the increasing depletion of fossil energy and increasing concern for environmental protection,propeller propulsion devices with high propulsion efficiency and low fuel consumption have received increasingly more attention than jet propulsion devices,ushering in new development opportunities.However,improving propulsion efficiency and reducing noise pollution have been major challenges in developing propeller aircraft.This paper thoroughly discusses the aerodynamics and aeroacoustics of the aviation propeller.At first,it summarizes the development history of propellers.Then,given the key aerodynamic problems,such as the aerodynamic characteristics of propellers and the propeller airfoils,the research status and the key progress are summarized and discussed from theoretical analyses,numerical calculations,wind tunnel experiments,and other research methods and techniques.Finally,the research achievements and the latest progress regarding the propeller aircraft aerodynamic noise at home and abroad are introduced,including the mechanism,prediction,and reduction of propeller noise;prospects for future research on aircraft propeller aerodynamics,noise,and optimization design are also presented.
