Claims

[Scope of utility model registration request]

In a wiper device for wiping away flying objects adhering to a windshield of a traveling aircraft, a nozzle injection device having at least two nozzle pipes communicating with a compressed air supply source and extending toward both ends of the windshield is provided immediately before the windshield. and jetting compressed air from a jet port formed in the longitudinal direction of each nozzle pipe to form a plurality of shielding air films at intervals, and forming an intermediate air film between the shielding air films;
Furthermore, an air jet wiper characterized in that a rectifying plate is provided in front of the shielding air film to deflect upward the airflow generated by the vehicle, and the deflected airflow generated by the rectifying plate is formed in front of the shielding air film. Device.
