FIELD: aeronautical engineering. SUBSTANCE: nose undercarriage leg includes shock-absorber strut articulated to fuselage structure and wheel fork and vibration damper. Shock-absorber strut is just spring made in form of bent plate and provided with additional support rigidly connected with fuselage structure. Shock-absorber strut is connected with wheel fork by means of pivot rigidly secured on end of bent plate. Vibration damper is made in form of plate springs mounted on this pivot and supported (through washer) by friction bush movable along pivot. EFFECT: simplified construction; reduced mass; ease of maintenance; proper characteristics of absorption and dissipation of kinetic energy of aircraft at landing and running on ground; dampening self-oscillations of leg. 5 dwg
