If a person who drives normally encounters a rainy day, he will wipe out the wiper to remove the rain and ensure the driving vision is clear. But what should we do if the plane that emphasizes safety is most exposed to rain? CNC machining parts Manufacturer in Xiamen, China.
Most airplanes have wipers installed, sailing on rainy days, and relying on windshield wipers for slow speeds. The special Honda business jet, which does not have a wiper, jagged under the porthole, creating a turbulent flow that sweeps away raindrops. In addition. The fighter will not install a wiper, so how does it get rid of rain in the rain? CNC machining parts Manufacturer in Xiamen, China
In fact, most airliners, transport aircrafts and helicopters are equipped with wipers, because these aircraft are slow to fly, and it is easy to form fog on the windshield glass during rainy days, affecting the pilot’s vision of flight and causing flight hazards.

Take civil airliners as an example, the front two windshields are relatively large and flat, and it is relatively easy to install wipers. CNC machining parts Manufacturer in Xiamen, China
However, fighter aircraft are different, regardless of whether the pilot’s omnidirectional field of view uses a bubble-type canopy, or take into account the aerodynamic resistance using a smooth canopy, whether integral or bulkhead type, the canopy is mostly arc-shaped, Installing a wiper is not easy to implement.

In addition, compared to civil aviation passenger aircraft, transport aircraft and helicopters, fighter jets can fly much faster, so the air resistance during flight is also greater, which is very unfavorable for the installation of wipers. CNC machining parts Manufacturer in Xiamen, China
So how did the fighter get rid of rain in the rain?
In fact, even if the wiper is not installed, the fighter can effectively solve the problem of rain and fog. Drain fluid can be applied to the windshield, which can increase the surface tension of the water, keep the water in a bead, and accelerate the slide away from the glass during flight without sticking to the windshield surface.

Or a water-repellent coating on the surface of the windshield glass, which is a coating that does not absorb rainwater and strongly repel the rainwater. After the rainwater hits the windshield, it will form an engraved droplet of water.
The cockpit cover of the modern cockpit is also heat-retaining. In order to prevent the formation of water mist on the surface of the cockpit cover at low temperatures, pairs of metal wires are used as heating and defogging electrodes on the windshield of the cockpit cover.

There is also an ultrasonic rain removal technique, in which a high-frequency ultrasonic generator is installed under the windshield to quickly remove the attached matter such as rainwater and dust attached to the surface of the windshield glass.
Of course, not all fighter jets are windshield wipers. The exception is the British Capricorn vertical takeoff and landing fighter. A small area of wiper is installed in front of the canopy.
However, this fighter can install a wiper because the fighter is a vertical take-off and landing, and the speed of take-off and landing is relatively unpleasant. In addition, modern fighter jets are basically not equipped with wipers.
