Abstract

本发明公开了一种能降低喷气式飞机喷气噪声的装置，其特征是：在飞机发动机排气门的尾部外侧间隔对称设置四个阻波器。本发明的优点是：阻波器的气流经迎风面后突然向排气门中部冲去，与排气门排出的噪声波干扰搅和，以降低飞机喷气噪声。

Description

一种能降低喷气式飞机喷气噪声的装置
技术领域
本发明涉及飞机噪声，具体是一种能降低喷气式飞机喷气噪声的装置。
背景技术
飞机发动机的噪声可达100-140分贝，造成噪声污染，影响人体健康，目前的解决方法只能把机场建立在距离市区和居民区较远的地方。
发明内容
本发明的目的是提供一种能降低喷气式飞机喷气噪声的装置。
实现本发明目的的技术方案是：
一种能降低喷气式飞机喷气噪声的装置，是在飞机发动机排气门的尾部外侧间隔对称设置四个阻波器。
所述的阻波器为一个呈钝角三角形的凸起。
所述的阻波器高0.3-0.5米，长1米。
本发明的优点是：阻波器的气流经迎风面后突然向排气门中部冲去，与排气门排出的噪声波干扰搅和，以降低飞机喷气噪声。
附图说明
图1为本发明能降低喷气式飞机喷气噪声的装置结构示意图；
图2为图1的仰视图。
图中：1.排气门  2.阻波器。
具体实施方式
参照图1-2，一种能降低喷气式飞机喷气噪声的装置，是在飞机发动机排气门1的尾部外侧间隔对称设置四个高0.3-0.5米，长1米的阻波器2，阻波器2为一个呈钝角三角形的凸起。
