METHOD AND DEVICE TO CONTROL AIRCRAFT IN ROLLOUT Russian patent published in 2009 - IPC B64C13/02 

FIELD: aircraft control.

SUBSTANCE: proposed method consists in setting the difference between instructions on LH and RH braking. Aforesaid difference if transformed into extra instruction to control rudder and undercarriage controlled front strut. Aforesaid extra instruction is sent to the rudder and aforesaid strut observing dual condition consisting in that the braking instruction difference exceeds the 1^st threshold and combined control instruction sent by the rudder control lever to the rudder and undercarriage controlled front strut, and is smaller than the 2^nd threshold. Proposed device comprises undercarriage controlled front strut, rudder, rudder control lever, undercarriage two struts arranged in symmetry with each other along aircraft midplane vertical axis. Note here that undercarriage wheels are furnished with brakes, brakes control two elements, circuitry to generate difference between braking instructions, operating generator, circuitry to transform the function into extra control instructions for rudder and undercarriage controlled front strut, restricting circuitry, that to generate the sum of combined control instruction and extra control instruction restricted by restricting circuitry, circuitry to send aforesaid sum to the rudder and undercarriage controlled front strut.

EFFECT: increasing turn actuator moment.
