| 摘 要： | 本文通过座舱盖跨声速阻力的试验研究及理论计算程序的设计,建立了高速座舱盖参数选择、工程估算及理论计算预测性能的方法,完成了试验前的理论设计工作。经4个系列13个座舱盖模型的试验,分别研究了座舱盖最大高度、最大宽度、细长比及风挡后倾角对阻力特性的影响,为高速飞机座舱盖气动设计的参数选择提供了一般准则;并为座舱盖跨声速阻力的工程估算提供了应用曲线。本文用有限差分法建立了可适用于不同外形的机身-座舱盖的压力分布及气动力计算的程序。

| Abstract: | This paper described experiment investigation of tran-sonic drag characteristics and design of theoretic calculation programfor close cabin,and established the methods of parameter choice,engi-neering estimation,an pre-estimate property with theoretic calculationfor high speed close cabin.Theoretic design was completed before test.Experimental study of effect of maximum height and width,slen-derness ratio and backward angle of dip of window of close cabin ondrag characteristics was conducted respectively with 4 series and 13close cabin models.It provided general criteria for parameter choice ofaerodynamic design of close cabin of high speed aircraft and applica-tion curves for engineering calculation of transonic drag of close cabin.In this paper the programs of pressure distribution and aerodynam-ic calculation applied to different configurations for body-close cabinwere given by finite difference method. |
