Description

基于微型燃气轮机全电推进的无人飞行器
技术领域
本发明属于飞行器技术领域，具体涉及一种基于微型燃气轮机全电推进的无人飞行器。
背景技术
目前无人飞行器的电量供给方式主要为蓄电池，无人飞行器的续航时间比较短。若采用增大电池容量或者利用太阳能电板的方式，则会减小无人飞行器的推重比。效率不但无法提高，反而会降低。因此目前仍没有推重比较大、续航能力较强的无人飞行器。
发明内容
本发明为了解决现有的无人飞行器续航时间短、推重比较小等问题，提供了一种基于微型燃气轮机全电推进的无人飞行器，其具有续航时间长，推重比较大等特点，可以改善现有无人飞行器普遍存在的续航时间比较短、推重比较小的缺点。
本发明的技术方案：
一种基于微型燃气轮机全电推进的无人飞行器，包括微型燃气轮机1、启发一体机2、蓄电池3、空气动压箔片轴承4、电机及螺旋桨5和电子设备10；
所述的微型燃气轮机1包括压气机6、涡轮7和燃烧室8；压气机6通过燃烧室8连接涡轮7，空气9通过压气机6吸入到燃烧室8中，与燃料11混合燃烧，产生的燃气推动涡轮7旋转；
所述的启发一体机2、压气机6和涡轮7通过空气箔片轴承4固定在支撑轴上，空气箔片轴承4以空气作为润滑剂，不仅可以起到良好的润滑作用，而且还可以带走无人飞行器所产生的热量；启发一体机2利用蓄电池3中的电能带动压气机6工作，并通过涡轮7带动自身发电反馈给蓄电池3；蓄电池3通过电缆连接到电机及螺旋桨5和电子设备10上。
本发明的有益效果：
1)本发明利用微型燃气轮机发电，在燃料足够的情况下，可以给无人飞行器持续不断的供电，可以大大地提高无人飞行器长时间续航的能力。
2)本发明的轴承采用空气动压箔片轴承，空气不仅可以起到润滑轴承的作用，而且还能起到冷却轴承的作用，并且抛弃了传统的油润滑系统，大大简化了推进系统的结构和重量，增加了无人飞行器的推重比。

具体实施方式
下面结合附图对本发明的结构示意图作进一步详细的说明，
如图1和图2所示，一种基于微型燃气轮机全电推进的无人飞行器，包括微型燃气轮机1、启发一体机2、蓄电池3、空气动压箔片轴承4、电机及螺旋桨5和电子设备10；
所述的微型燃气轮机1包括压气机6、涡轮7和燃烧室8；压气机6通过燃烧室8连接涡轮7，空气9通过压气机6吸入到燃烧室8中，与燃料11混合燃烧，产生的燃气推动涡轮7旋转；
所述的启发一体机2、压气机6和涡轮7通过空气箔片轴承4固定在支撑轴上，空气箔片轴承4以空气作为润滑剂，不仅可以起到良好的润滑作用，而且还可以带走无人飞行器所产生的热量；启发一体机2利用蓄电池3中的电能带动压气机6工作，并通过涡轮7带动自身发电反馈给蓄电池3；蓄电池3通过电缆连接到电机及螺旋桨5和电子设备10上。
微型燃气轮机1由静止启动时，需要用启发一体机2带着压气机6和涡轮7一起旋转，压气机6吸入空气，然后压缩、燃烧，在燃烧室8燃烧后产生高温高压的燃气进入涡轮7，推动涡轮叶片高速旋转；涡轮7做的功一部分用于带动压气机6正常工作，从而使微型燃气轮机1持续不断地工作；另一部分的功用于带动启发一体机2进行发电，产生的电能用于电机及螺旋桨5直接产生无人飞行器所需的推力并同时储存于蓄电池3中，从而达到长时间续航的目的。
