A measurement system for measuring friction coefficient of aircraft runway is designed. The system consists of hydraulic system

speed transmission system

sprinkler system and control system. It mainly completes the mechanical action during the measurement process

the slip ratio

the state of the aircraft after the rain

and the control of various electrical equipment. The system enables real-time calculation

display

storage and printing of the coefficient of friction. Through multiple measurements

the result proves that the measurement system has accurate and repeatable coefficient of variation of less than 4. 4 %. Result meets the measurement rule of friction coefficient. At the same time

the system is safe and reliable

simple and convenient to operate

and can realize automatic continuous measurement.
