FIELD: aviation equipment.
SUBSTANCE: during tests, auxiliary modes are additionally performed: run modes on aborted takeoff and landing without the use of wheel braking to a steady speed in the same aircraft configuration using aerodynamic braking and engine operating modes, as well as on a run with wheel braking, runs at a minimum mode operation of the engines from the moment of pulling away to the steady speed of the aircraft, rolling the aircraft with the engines turned off with the help of a towing vehicle using a dynamometric thrust to determine the coefficient of rolling friction. Then the dependences of the longitudinal overload on the ground speed of the aircraft are formed, and the proportion of the longitudinal component of the overload is determined due to the braking of the wheels. The braking torque is calculated, the energy load of one wheel is determined.
EFFECT: increased efficiency of flight tests and reliability of the results of evaluation of the braking torque, the energy load of the wheels of the landing gear to determine the maximum speed of the start of braking of the wheels and the run distances.
