Abstract

中空长航时无人机设计最大难点是机翼翼型，要求很高的升阻比和很线性的升力或攻角特性。高升阻比保证发动机的低耗能，用以解决航程-速度和能耗的矛盾，BDM-WFI翼型在100-110公里飞行时能耗非常低，升阻比高达16-17。因此BDM-B飞机飞行一小时，飞行距离100公里，仅消耗汽油0.7升。

Description

中空长航时无人机机翼翼型
技术领域
中空长航时无人机BDM系列机翼翼型BDM-WFI设计。
背景技术
BDM-WFI是适合飞行速度50公里-180公里/时轻型长航时无人机设计的翼型，经气动力计算和实际飞行测试，具有高升阻比性能，较宽的稳定性余度。设翼型中弧线相对弯度为4.8%，相对厚度为8.4%。（具体可提供图型）。
发明内容
BDM-WFI翼型。

Claims (2)

1.有翼飞行器设计中最重要的设计部分是翼型设计，本文所描述的翼型是用于飞行速度从50公里/小时到180公里/小时有翼无人机的机翼的翼型和其特性。
2.BDM翼型I适用于中空长航时无人机的翼型，相对厚度为8.4%，相对弯度为4.8%，凹凸翼型，在飞行器飞行速度在50-180公里/时范围内具有很高的升阻比，良好的翼面气动力分布，升力曲线随仰角变化呈非常好的线性特征，这种特性使采用此翼型的飞行器具备稳定的飞行品质，适用于中空长航时的侦查、地貌跟踪任务。
