ELECTROMECHANICAL POWER MINI DRIVE OF AIRCRAFT MOVING AIRFOIL CONTROL WITH WING SECTION FOLDING AND UNFOLDING FUNCTIONS Russian patent published in 2015 - IPC B64C13/50 

FIELD: aircraft engineering.

SUBSTANCE: invention relates to ACS for aircraft with wing sections folding before and after the flight. Proposed mini drive consists of electrical drive, multistage reduction gear with output section including input, idle and output links of wave transmission with balls and output link position transducer. Note here that electromagnetic locking device is fitted in between mid and locking section of reduction gear so that at its dead state said stiff wheel of reduction gear output section makes an output link and is provided with elements for securing to airfoil while separator is locked with mid stage case. At locking device electromagnet IN state, said stiff wheel is clocked at mid section case while separator makes the reduction gear output stage output link.

EFFECT: efficient wing section folding/unfolding and in-flight control over aircraft airfoil.
