Rain Protection Flashcards
Does a windshield wiper system works on a dry windshield?
NO, they are used when needed so it needs to be in a good working condition
Types of rain protection
WIPER SYSTEM
LIQUID REPELLENT
AIR PRESSURE
BY CHANGING THE VOLTAGE APPLIED TO THE WINDSHIELD-WIPER, MOTOR THE SPEED CONTROL IS ACCOMPLISHED.
BY TURNING THE WINDSHIELD-WIPER SWITCH TO A SELECTED SPEED, THE REQUIRED RESISTANCE AND VOLTAGE IS CONNECTED INTO THE MOTOR CIRCUIT.
THE WINDSHIELD-WIPERS ROTARY MOTION IS TRANSMITTED BY THE FLEXIBLE SHAFT TO THE CONVERTER.
THE SPEED REDUCTION OF THE SHAFT AND THE CHANGE OF THE MOTION FROM ROTARY TO OSCILLATING IS ACCOMPLISHED BY THE CONVERTER.
Electrically
Type of rain protection both need pressure supply to be directed in a actuator
Pneumatic and hydraulic
Type of rain protection CAUSES THE WATER TO FORM SMALL GLOBULES THAT CAN QUICKLY BE BLOWN AWAY BY THE RUSH OF AIR OVER THE WINDSHIELD IN FLIGHT.
It can damage the window if left on
Liquid Repellent
An OLDER METHOD BASED ON THE USE OF ENGINE BLEED FROM THE TURBINES OF TURBINE-POWERED AIRCRAFT TO PREVENT RAIN FROM STRIKING THE WINDSHIELD.
