FIELD: aircraft engineering.
SUBSTANCE: invention relates to aircrafts. Propulsion device (1) for an aircraft, such as a turbo-propeller aircraft, comprises torque generator (2), activating output shaft (3) through power transmission box (4). Output shaft (3) is rotatably connected to propulsor (5), and the power transmission box (4) is fixed to frame (7) by means of suspension means (8, 14, 15), which contain hydraulic means of torque recovery, comprising at least first hydraulic system (15) and second hydraulic system (15), spaced from each other. Each hydraulic system (15) comprises pressure chamber, volume of which varies in accordance with position of housing (9) of power transmission box (4) relative to frame (7). Pressure chambers of hydraulic systems (15) are connected by capillary channel so that hydraulic fluid medium can pass through one pressure chamber to another through capillary channel.
EFFECT: higher reliability of measurements.
