Abstract

空气由进气道7进入压气机，压气机旋转将空气压缩后，进入中空转轴2，通过进气孔6进入燃烧室，与喷油嘴5喷出的燃料混合燃烧，产生的高温高压气流推动涡轮4旋转，涡轮通过中空转轴带动压气机旋转。

Description

旋转式冲压喷气发动机
技术领域
本发明涉及一种利用旋转进气道压气的喷气发动机。
背景技术
目前，航空发动机按进气方式分主要有活塞式、涡轮式和冲压发动机。活塞式发动机主要应用在螺旋桨飞行器上用来驱动螺旋桨，由于螺旋桨体积大，效率低，其在航空器的上的应用受到一些限制。涡轮式发动机和冲压发动机的进气方向、喷气方向和飞行器的飞行方向基本平行，不便应用在垂直起降飞行器上。现有涡轮式发动机燃烧室前端通常有多级压气扇叶，使发动机整体造型上必须细长，限制了飞行器的的形体设计。现有冲压发动机机构简单，推重比大，可是不能自行起动，飞行器静止的时候不能工作。
发明内容
为了适应垂直起降飞行器的需要，本发明提供了一种结构简单，体积体积小，推重比大的旋转式冲压喷气发动机。
附图说明
下面结合附图对本发明作进一步说明。
图1是发动机的主要结构示意图，包括压气机1、中空转轴2、燃烧室3、涡轮4。
图2是压气机的俯视剖面图，8是进气口，9是压缩空气进气口。空气由8进入压气机，压气机旋转提高进气道静压，压缩后的空气从9进入中空转轴参与后面的工作。
具体实施方式
空气由进气道7进入压气机，压气机旋转将空气压缩后，进入中空转轴2，通过进气孔6进入燃烧室，与喷油嘴5喷出的燃料混合燃烧，产生的高温高压气流推动涡轮4旋转，涡轮通过中空转轴带动压气机旋转。

Claims (3)

1.一种旋转式冲压喷气发动机，包括旋转式压气机、中空转轴、燃烧室、涡轮，其特征是有旋转的冲压压气机。
2.根据权利要求1所述，一种旋转冲压压气机，包括一个或多个同样的进气道，其特征是入口开阔出口收敛。
3.根据权利要求2所述，一种中空转轴，其特征是转轴中心是空的，其上端开口与进气道连通，在燃烧室有进气孔。
