METHOD OF LOADING AIRCRAFT BRAKE CONTROL SYSTEM FOOT STATION PEDALS AND FOOT STATION PEDAL ASSEMBLY TO THIS END Russian patent published in 2014 - IPC B64C25/44 

FIELD: transport.

SUBSTANCE: invention relates to aircraft brake remote control system incorporating both pedal and automatic control modes. To load pedals of aircraft wheel brake foot control station brake pedal is depressed to turn it. At pedal turn force is applied thereto by pedal spring loader under normal braking conditions (NB) owing to loader spring expansion. At further turn of the pedal under NB conditions with higher retardation characteristic via simultaneous action of expansion and compression springs. At changing from NB mode to NB mode with higher retardation characteristic load at pedal is increased in stepwise manner owing to overcoming of prestressed compression spring at initial stage of its squeezing. Spring loader comprises upper bracket, rod with bearing site, lower moving bracket arranged to slide on the rod at brake pedal turn and consists of two halves surrounding the rod, and expansion springs. The latter are connected with upper bracket by one end and with lower bracket by opposite end to slide thereon to interact via mid element with pre-contracted compression spring. Compression spring thrusts against the rod bearing site made at its free lower end. Mid element interacts with spring loader fixed part by one end and with free end of compression spring by opposite end.

EFFECT: higher reliability of aircraft braking system.
