    摘要: In some embodiments, a rotorcraft includes a fuselage (10), a tailboom (24), a drive system (38) and a variable thrust cross-flow fan system (32; 100). The cross-flow fan system (32; 100) includes a cross-flow fan assembly (102) that is mechanically coupled to a drive shaft (108) and operable to rotate with the drive shaft about a longitudinal axis. The cross-flow fan assembly (102) includes first and second driver plates (104, 106) having a plurality of blades (110a-110g) rotatably mounted therebetween. The blades are disposed radially outwardly from the longitudinal axis and have a generally circular path of travel when the cross-flow fan assembly (102) rotates about the longitudinal axis. The blades (110a-110g) are moveable between a plurality of pitch angle configurations. A control assembly (130, 134a-134g, 142a-142g) is coupled to the blades. The control assembly (130, 134a-134g, 142a-142g) is operable to change the pitch angle configuration of the blades (110a-110g) to generate variable thrust at a substantially constant rotational speed of the cross-flow fan assembly (102).

    摘要: The invention relates to aviation technology, specifically to vertical take-off and landing aircraft. The vertical take-off and landing aircraft comprises two turbines, the lower of which is of plate-like shape, and the upper is of flat or plate-like shape. Each turbine comprises a reactive power plant. The body of each turbine is mounted on a metallic disc connected to a vertical shaft of the aircraft, and is equipped with vanes. The vanes are mounted such that the position thereof can be changed. The aircraft can comprise intermediate turbines which are mounted between the upper and lower turbine and are flat or plate-like. The reactive power plant of each turbine comprises an air engine and receivers which are connected to a compressor. The body of each turbine is metallic and comprises two rings, one of which is connected to the disc, and also radial struts which are mounted along the perimeter of the turbine body and are connected to the rings and vanes. The vanes are mounted in a single row along the perimeter of the body or are arranged in a single tier. The result is an increase in the reliability and economy of the aircraft, and the possibility of the latter moving vertically, horizontally or at any inclination.
