FRAMEWORK Russian patent published in 2018 - IPC B64C5/02 B64C5/16 

FIELD: aviation.

SUBSTANCE: invention relates to aircraft engineering. Airframe includes fuselage, wing with ailerons, control system, horizontal and vertical plumage. Horizontal tail is mounted on fuselage, is connected to control system and consists of stabilizer comprising the main part connected to the control system in the longitudinal channel, and root inflows with incoming edges adjacent to the leading edge of stabilizer and the lateral surfaces of fuselage. Means of longitudinal balancing including the deflectable surface and the drive mechanism are provided. Root influxes are made deflectable with respect to the fuselage and kinematically connected with the drive mechanism of the longitudinal balancing means. Length of the root influx is not less than 30 % of the span of the main part of the stabilizer, the spread of root influx in the zone of abutment to the main part of the stabilizer is at least 25 % of the span of the main part of the stabilizer. Drive mechanism of the longitudinal balancing means is made with a self-locking output link.

EFFECT: invention is aimed at improving flight safety while piloting training.
