FIELD: aviation.

SUBSTANCE: invention relates to the field of aviation, in particular to take-off and landing devices for aircraft, including helicopters. The take-off and landing device of the rotary-wing aircraft contains two main bearings, one front bearing and a tail bearing. The main support of the take-off and landing gear consists of a shock absorber (1), a wheel (2), a semi-axle (3), a brace (4) and a wheel (6). Between the semi-axis (3) of the main support and the fuselage, a cardan (5) is installed, in the wheel 6 of the main support of the take-off and landing gear, a disc brake, bearings (16), a holder (17) and a ring (18) are installed. A cuff (19) and a felt ring (20) are installed in the holder (17). The retaining ring (21) fixes the flange (22), which in turn fixes the tire to the wheel (6). The take-off and landing device is equipped with sensors of the mass and balance measurement system. The mass and centering measurement system includes a central controller unit for measuring the mass and position of the center of mass (25), a pitch and roll sensor (26), force sensors (27, 28), force sensors (29, 30, 31), a rotation angle sensor 32, blocks for processing data from sensors (33, 34, 35).

EFFECT: improving the safety of helicopter movement on the ground, increasing the life of the chassis.
