Construction


Medium and medium haul transport aircraft. Intended mainly for transporting people. The crew consists of 3-5 people. As a standard, the crew consists of two pilots, a navigator, radiotelegraphist and deck mechanic. In cruise flights, the crew consists of only two pilots. 44 - 52 passengers can be taken on board. Twin-engine high wing, half-shell design. The aircraft is adapted for use with ground surfaces.

Five-part, double-girder wing. The wedge angle is 3 degrees. The outer parts of the wings have a negative rise of 2 degrees. The wings are equipped with flaps and ailerons. Shuttlecocks are made of glass laminate. They were balanced massively and equipped with balancing flaps. Double-section Fowler graying flaps are hydraulically driven. The internal flaps are single-slot, the external are double-slot. Engine wings are attached to the wings together with the main chassis chambers. The leading edges are made as channels through which hot air flows for de-icing the wings.


The fuselage is technologically divided into three main parts. The front part begins with a honeycomb laminate cover under which the equipment is placed. The crew cabin is intended for 5 crew people; two pilots, a navigator, radio operator and on-board mechanic. In the upper part of the crew cabin there is a hatch for emergency crew leaving the aircraft. A luggage compartment was placed between the crew and passenger cabin, which is also accessible from the outside of the aircraft through the door in the starboard side. There is also a room for flight attendants in this part of the aircraft and meals are prepared here. The passenger cabin has 44 - 52 seats in a typical 2 x 2 arrangement with a transition in the middle. It was equipped with 16 windows, 8 on each side. There are very few windows and not all passengers could enjoy the view through the window. Some of these windows are emergency exits. In the rear of the hull on the port side there is a door through which passengers board. There is one more luggage room in the tail, which is also accessible through the door on the starboard side. The crew cabin, passenger compartment and luggage compartments are air-tight and air-conditioned.

Classic setup divided into rudders and ballasts. The horizontal is mounted with a strong rise. Vertical with high inflow. The edges of the tail are de-iced with warm air.


Three-support chassis with front wheels. All wheels are double. The front assembly is retracted to the hull backwards. Controlled left-right, using a hydraulic system. Main chassis with long shins, retractable forward to the chambers located in the engine nacelles. The main undercarriage covers have large ribs to use as large tires as possible. The covers are still closed, and they only open to extend or retract the chassis. This protects the chambers against dirt. Oil-gas (nitrogen) shock absorbers placed in the shins. The hydraulic system retracts and extends the landing gear, turns the front assembly, brakes with the main landing gear wheels. Emergency opening of the chassis under its own weight.
