Abstract

本实用新型涉及飞机结构设计技术领域,特别是涉及一种飞机的翼尖探头。本翼尖探头包括探头舱、探杆与探头舱过渡段、探杆以及探杆与机翼翼尖过渡段,其中,探测设备安装在探头舱内,探头舱与探杆一端连接,连接处有平滑过渡的探杆与探头舱过渡段,探杆另一端与机翼翼尖连接,连接处有平滑过渡的探杆与机翼翼尖过渡段,探头舱外形为流线形,探杆横截面具有翼型外形。与以前的探头相比,飞机在安装新探头后,阻力增加不明显,升力有所增加,机翼气动特性得到改善,既能满足安装外部探测设备的设计需要,又能保证了飞机的飞行安全和性能指标。

Description

一种飞机的翼尖探头
技术领域
本实用新型涉及飞机结构设计技术领域,特别是涉及一种飞机的翼尖探头。
背景技术
在进行高空探测系统设计时,需要在机翼的翼尖处安装翼尖探头,以便在探头内安装探测设备。
现有飞机机翼翼尖外形是基于气动特性设计的,不能满足安装探测设备的需要。现有翼尖探头为90年代设计,探头、探杆外形基本为旋转体,对气动特性影响大,通用性不好。
发明内容
本发明的目的:
在满足探测设备安装对探头设计要求的前提下,通过气动分析和CFD计算,优化设计了一个机翼翼尖探头,能确保安装外部探测设备的同时降低对飞机原有气动特性的不利影响。具有能实现改装功能,
本发明的技术方案:
一种飞机的翼尖探头,包括探头舱、探杆与探头舱过渡段、探杆以及探杆与机翼翼尖过渡段,其中,
探测设备安装在探头舱内,探头舱与探杆一端连接,连接处有平滑过渡的探杆与探头舱过渡段,探杆另一端与机翼翼尖连接,连接处有平滑过渡的探杆与机翼翼尖过渡段,探头舱外形为流线形,探杆横截面具有翼型外形。
本发明的技术效果:
通过气动分析和CFD计算,优化设计的一种飞机的翼尖探头,适合于机翼翼尖需要安装附加设备的改装设计。试飞结果表明,与以前的探头相比,飞机在安装新探头后,阻力增加不明显,升力有所增加,机翼气动特性得到改善,既能满足安装外部探测设备的设计需要,又能保证了飞机的飞行安全和性能指标。

图5:安装本翼尖探头的飞机示意图。
具体实施方式
一种飞机的翼尖探头,包括探头舱、探杆与探头舱过渡段、探杆以及探杆与机翼翼尖过渡段,其中,
探测设备安装在探头舱内,探头舱与探杆一端连接,连接处有平滑过渡的探杆与探头舱过渡段,探杆另一端与机翼翼尖连接,连接处有平滑过渡的探杆与机翼翼尖过渡段。
探头舱,用于安装探测设备,探头外形为流线形,在保证有足够安装设备空间的前提下,优化探头外形,以降低探头的空气阻力。
探杆与探头舱过渡段,用于改善探杆与探头舱连接处的气流品质,降低探杆与探头舱之间的干扰阻力。
探杆,用于支撑探头,在保证探头与机翼翼尖之间有足够的距离的前提下,有足够的结构强度,保证探头在飞机飞行过程中姿态稳定。探杆横截面具有翼型外形,以降低探杆的空气阻力。探杆安装在翼尖展长的34%处,使探杆弦线与机翼弦线成2°夹角,保证飞机飞行时探杆与探头舱保持水平。
探杆与机翼翼尖过渡段,用于改善探杆与机翼翼尖连接处的气流品质,降低探杆与机翼翼尖之间的干扰阻力。
