FIELD: engines and pipes. ^ SUBSTANCE: plain contains fuselage, wing, horizontal and vertical empennage, the power plant, systems and equipment. The fuselage has changing geometry, generated by radial arc, which in the upper, lower and side part smoothly pass into the wing segment, generating together integral construction. The segment of the brad is made as the circle, and its diameter coincides with diameter of the narrow-bodied airplane, the profile of the middle part is made as ellipse with bigger horizontal axis and with relation of the height and the breadth of ellipse 1:3, integrally included to the wing construction. The fuselage tail section, where is fixed the horizontal and vertical empennage, is generated as integral construction with round profile and plain deposit, smoothly pass into ellipse. ^ EFFECT: it is exceeded the aerodynamic quality. ^ 7 dwg |
