The invention provides an aircraft airspeed tube extension tube, which belongs to the technical field of airspeed tubes, and comprises a first extension tube, a second extension tube and a first clamping piece, the front end of the second extension pipe is provided with a first transfer groove formed in the radial direction, and a pair of sliding grooves are formed in the axial direction of the second extension pipe; the rear end of the first extension pipe is hinged between the pair of sliding grooves through a hinge piece slidably arranged in the pair of sliding grooves, and when the first extension pipe rotates relative to the second extension pipe with the hinge piece as the axis to form an included angle, the first extension pipe is fixedly connected to the second extension pipe through a first clamping piece. The technical scheme has the beneficial effects that compared with a non-folding airspeed tube extension tube structure on an existing aircraft, the airspeed tube extension tube structure has the advantages that the course size of the aircraft in a transportation state is greatly reduced, the transportation efficiency is improved, the transportation cost is reduced, and the airspeed tube extension tube structure can be applied to most aircrafts with airspeed tubes arranged at the heads.

    本发明提供一种飞行器空速管延长管,属于空速管技术领域,包括:第一延长管、第二延长管和第一夹持件;第二延长管前端设有沿径向开设的第一转接槽,以及沿第二延长管的轴向方向开设有一对滑槽;第一延长管后端通过可滑动地设于一对滑槽内的铰接件铰接于一对滑槽之间,第一延长管以铰接件为轴线相对于第二延长管转动形成夹角状态时,通过第一夹持件固定连接于第二延长管。本发明的技术方案的有益效果在于,同现有飞行器上非折叠式空速管延长管结构相比,极大地缩减了飞行器在运输状态时的航向尺寸,提高运输效率,降低运输成本,可以应用于大多数在机头布置空速管的飞行器型号。
