成果简介	NOVELTY - The airfield brake trolley has a trolley structure (1) that is provided with a cover. A drawbar (2) is located longitudinally along a trolley axis. A wheel (5) is mounted on right and left shafts. A measuring unit with a strain gauge sensor, and consists of movable and fixed portions. The fixed portion is rigidly fixed to the trolley structure and includes two guides in which a movable portion is installed, made in the form of a carriage with two friction bearings mounted on the fixed portion, and a strain gauge sensor is fixed at one end to the fixed portion of the measurement unit, and at the other end of the strain gauge sensor is connected by a rod to the movable portion of the measurement unit. A /global navigation satellite system (GLONASS) antenna for the system for determining and transmitting coordinates of the trolley location and the distance traveled. USE - Airfield brake trolley for determining braking conditions of aircraft pneumatic wheels. ADVANTAGE - The airfield brake trolley improves the accuracy of determining the coordinates of the trolley location, the distance traveled and the speed, which are necessary to display the graph of the dependence of the coefficient of adhesion on the distance traveled. The accuracy of measuring the value of the coefficient of adhesion in reference to the coordinates of the specified route increases and the ability to accurately localize sections of the route with an excess value of the coefficient of adhesion is ensured. DESCRIPTION OF DRAWING(S) - The drawing shows a side view of the airfield brake trolley. 1Trolley structure 2Drawbar 3Towing hitch 4Adapter 5Wheel
