FIELD: wide-fuselage aircraft. SUBSTANCE: nose part of aircraft fuselage includes pressurized compartment 20 and non- pressurized compartment 18 used for nose undercarriage in stowed position forming lower nose end section of nose part of aircraft fuselage. Compartment 18 is separated from pressurized compartment by means of ceiling 14 which may sag downward and rear partition 16 reinforced with stiffeners. Compartment 18 may have rear projection 18a extending beyond rear partition and nose undercarriage is secured by means of hinge in rear part of projection entering undercarriage compartment in stowed position. Rear projection has inclined side partitions which meet at the top of undercarriage compartment. Rear partition is provided with at least one hatch which is practically oval in shape and its main axis is vertical. Radar compartment is located before undercarriage compartment. EFFECT: improved aerodynamic properties; extended functional capabilities. 13 cl, 5 dwg
