The invention provides a jet rotor wing pipeline and a rotor wing / wing with the jet rotor wing pipelineand an aircraft. The jet rotor wing pipeline is provided with a jet inlet and a jet outlet, the jet outlet profile is designed as follows that the jet outlet profile comprises an inner profile line and an outer profile line which are in elliptic-like shapes, the outer profile line is expanded in equal proportion to the inner profile line, the inner profile line is composed of a first circular-arc-shaped line, a first arc-shaped line, a second circular-arc-shaped line and a second arc-shaped line which are sequentially and smoothly transitioned, wherein the first circular-arc-shaped line is arranged away from a rotor wing tip, the second circular-arc-shaped is arranged close to the rotor wing pin, and the radius of the first circular-arc-shaped line is larger than the radius of the second circular-arc-shaped line. According to the jet rotor wing pipeline, the technical problem of the performance degradation of the jet rotor wing caused by the design of the inner nozzle of the rotor wing in an existing CRW aircraft.
Description
technical field [0001] The invention relates to the technical field of aircraft aerodynamic shape, in particular to a jet rotor duct, a rotor / wing and an aircraft with the same. Background technique [0002] Helicopters can take off and land vertically, but cannot cruise at high speeds. Canard Rotor / Wing (Canard Rotor / Wing, CRW) aircraft is a new concept flight platform capable of vertical take-off and landing, high-speed cruise, its outstanding feature is to combine the advantages of helicopters and fixed-wing aircraft, and to avoid the disadvantages of both. CRW has design features that distinguish it from other high-speed vertical take-off and landing technology aircraft: rotatable rotor and propeller tip jet drive. [0003] The jet-driven rotor generates reaction force through the wingtip high-speed jet to drive the rotor to rotate. Compared with the shaft-driven rotor, it eliminates the heavy gear transmission system and anti-torque system, effectively reduces the com...
