FIELD: measuring equipment.
SUBSTANCE: method of determining the adhesion coefficient of object wheels with aerodrome pavement includes measuring the dynamic characteristics of the vehicle wheels when it travels over the airfield cover, determining the dynamic characteristics of the vehicle body by installing devices on the object, and the coupling properties of the airfield cover are determined from the difference in the speed of the object body and the speed of movement of the object's body, determined by the speed of rotation of the wheels of the object, with zero difference the coefficient is linked aerodrome coverage is maximum, when the difference in the threshold speed is reached, a warning signal is generated and the signals proportional to the velocities and the difference signal are recorded, in addition, the speed of the object body displacement determined by the wheel speed of the object is determined taking into account the deformation of the tires from the aircraft load. The device for measuring the coefficient of adhesion of the wheels of an object with an aerodrome covering contains a recording equipment, a sensor for measuring the wheel speed, mounted on the chassis, an object speed detection unit according to the wheel rotation frequency, and an object speed measuring unit made in the form of a navigation unit in combination with a satellite receiver navigation system, a subtraction unit, a threshold device and an alerting unit. The output of the wheel speed sensor is connected to the first input of the object speed detection unit according to the wheel speed, the output of which is connected to the first inputs of the subtracting unit and the recording equipment, the output of the subtraction unit through the threshold device is connected to the input of the notification unit and the third input of the recording equipment. The device comprises a wheel radius measurement sensor mounted on a chassis the output of which is connected to the second input of the object speed detection unit according to the wheel speed.
EFFECT: increasing the accuracy of measuring the coefficient of adhesion of the airplane wheels to the airfield while driving through the aerodrome, taking into account the aircraft load.
