The invention provides a flute-shaped pipe anti-icing device with jet airflow on an airplane. The anti-icing device comprises a flute-shaped pipe, a sealing mechanism and a driving mechanism, whereinthe flute-shaped pipe is provided with an inlet end and a plurality of nozzles, the sealing mechanism enables the flute-shaped pipe to be rotatably sealed on an installation component, and an inlet end is arranged on the outer side of the installation component; the driving mechanism enables the flute-shaped pipe to rotate relative to the installation component so as to change the spraying angle of the nozzle; the driving mechanism comprises a transmission unit with an input end and an output end and a servo motor for driving the transmission unit, the output end of the transmission unit is intransmission connection with the flute-shaped pipe, and the servo motor is connected to the input end of the transmission unit to drive the transmission unit and drives the transmission unit according to the change of the attack angle of the airplane; and the flute-shaped pipe rotates relative to the mounting component, so the spraying angle of the nozzle of the flute-shaped pipe is changed. Technical problems that in the prior art, heat efficiency is low, and the structure is complex are solved.

    本发明提供一种飞机上具有喷射气流的笛形管防冰装置,防冰装置包括笛形管、密封机构和驱动机构,笛形管具有入口端和多个喷口,密封机构使笛形管可转动地密封到安装构件上,入口端在安装构件的外侧,驱动机构使笛形管能够相对安装构件转动以改变喷口的喷射角度。其中,驱动机构包括具有输入端和输出端的传动单元和驱动传动单元的伺服电机,传动单元的输出端传动地连接于笛形管,伺服电机连接于传动单元的输入端以驱动传动单元,并根据飞机攻角变化驱动传动单元,使得笛形管相对安装构件转动,从而改变笛形管的喷口的喷射角度。本发明解决了现有技术中热效率低、结构复杂的技术问题。
