Four Bar Software Norton Four rotating joints: A flat quadrilateral link is formed by four links and four rotating joints, designated RRRR. The hinges RR45 and RR50 form a hinged axle rigidly connected to the rod, which forms the bearing surface. These hinges allow the transfer of tensile and compressive forces to the wing. Figure 6.3.1 - General view of the helicopter landing gear The co-pilot's seat is located in the sector of the lower hinge assembly. In the sections of the stabilizer there are regulators for the angle of deflection and the direction of rotation, as well as the air intake flaps of the power compartment of the engine, which open when approaching the ground. rice. 6.4.1. Cabin air conditioning system The helicopter developers believed that the maximum temperature of the helicopter cabin with the engine running should not exceed 37.2°C, therefore, internal equipment is used to cool the air inside the cabin, providing a temperature of 22...26°C. The antenna of the external communication system is located in the upper part of the fuselage on the right. To increase the stability and controllability of the helicopter during landing and takeoff, a rotary sliding system and a mechanical brake are used. The helicopter landing gear is designed to use wheels with a diameter of 900 mm and with lugs. To ensure all-round defense and create a course angle of attack, stoppers are installed from the rear landing gear. A folding swivel device is installed on the rear landing gear for landing and maneuvering with the engine turned off (Fig. 6.6). The cockpit of the helicopter is equipped with an air conditioning system. Unlike many other helicopters, where the air conditioning of the cabin air is provided by a fan at the rear of the flybridge, here cooling is carried out by gravity through a piping system laid in the lower engine air intake. On the left landing gear are the center section and engine air intakes. Design features and engine systems. The helicopter is equipped with Sikorsky CGE-450 engines, which have been adapted for installation on a helicopter. These engines are equipped with a liquid cooling system and a Pratt-Whitney fuel supply system. The advantages of CGI engines include: - reliable operation of engines in all flight modes; - high thrust-to-weight ratio; In addition, C, GE and GEJS engines have the best stability parameters for all types of air and ground loads. The crew cabins are highly comfortable. 3e8ec1a487
