UNFOLDING AERODYNAMIC STABILIZER OF AIRCRAFT

摘要

FIELD: aircraft industry. SUBSTANCE: proposed invention is related to aircraft positioned in field of heavy air disturbances. Unfolding aerodynamic stabilizer of aircraft has group of blades each mounted for turning on axle anchored on supporting element and fitted with drive for development of blades into open position which includes torsion and compression springs and mechanism registering each blade in unfolded position which includes recess made in supporting element to interact with root part of blade. Each blade is provided with additional turning drive positioned in parallel to rotational axis of blade and with mechanism transmitting torque to blade connected to additional drive and interacting with blade. Stopping element of root part of each blade is manufactured in the form of lug and supporting element has additional recesses which interact with proper lugs. Lugs and walls of recesses interact by means of bevels which planes are located at angle relative to axis of turn of corresponding blade. Additional drive of turn of blade is manufactured in the form of additional torsion spring put on additional axle placed in parallel to axis of turn of blade on supporting element, bushing with locating arm to fix and wind additional spring is put on additional axle. Mechanism transmitting torque to blade is manufactured in the form of bushing put on supporting element in parallel to axis of turn of blade. It has device to fix additional drive. Bushing carries lever, fork put on axle of turn of blade with lockpins interacting with mentioned lever and internal surface of blade. mechanism blocking each blade in fixed open position is provided with bevel made on front butt of this blade which plane is arranged at self-brake angle relative to lockpin of mechanism transmitting torque to blade interacting with it and interacting with internal surface of blade at moment of opening. EFFECT: increased operational reliability and improved stability of aerodynamic characteristics of stabilizer.
