| 摘 要： | 研究了势流理论下的全机增升装置复杂外形气动力数值计算方法,该方法以低阶面元法为基础,具有计算量小、速度快的优点.复杂流动的粘性效应主要通过附面层粘性修正技术加以体现.采用该方法对某增升装置翼身组合体外形压力分布特性进行计算,并和风洞实验数据相比较,验证了方法的正确性和实用性.在此基础上对某型飞机真实复杂外形的压力分布特性进行了计算,为复杂外形飞行器增升装置的初步设计、方案选型与评估提供了非常理想的工程技术手段.

| Abstract: | This paper presents a potential-based flow analysis tool for complex high-lift aircraft configuration.It has the advantage of computing speed,and takes the viscidity effect into consideration by boundary layer correction.First,we use it for a high-lift wing-body and compare the computational results with the experiment data.The good agreement indicates that the method is practicable.Then,a high-lift configuration for a realistic complete aircraft is analyzed.The computing practice shows that the method is a... |
