摘要： A vertical takeoff and landing aircraft having a fuselage with, preferably, three wings and six synchronously tilt-able propulsion units, each one mounted above, below, or on each half of the aforementioned three wings. The propulsion units are oriented vertically for vertical flight and horizontally for forward flight. Each propulsion unit comprises a propeller having a plurality of blades, where the pitch angle associated with the distal end of each blade and the proximal end of each blade are independently adjustable. As such, each of the propellers can be adjusted to exhibit a first blade pitch angle distribution optimized for vertical flight and a second blade pitch angle distribution optimized for forward flight.

摘要： There is described a1 variable pitch propeller comprising at least one blade pivoted rotatably to a cylindrical propeller casing (3), a drive shaft, coupled to a propulsor and positioned coaxially inside the propeller casing, a kinematic mechanism coupled to the drive shaft, or to the propeller casing, and to said blade, for adjusting the rotary motion of the blade or blades about its axis of pivoting to the propeller casing, and means for coupling in rotation the drive shaft to the propeller casing. The propeller is configured to provide at least one non-null angular range of relative rotation of the blade or blades about its axis of pivoting, with respect to the propeller casing, or vice versa. The means for coupling in rotation the drive shaft to the cylindrical propeller casing comprise at least one elastic element (8) interposed between the drive shaft and the cylindrical casing preferably acting at least when the propulsor drives in rotation the drive shaft according to at least one direction of rotation. The propeller also comprises at least one intermediate element (11) interposed between the drive shaft and the cylindrical propeller casing, provided with a first (20) and a second (21) contact surface with the drive shaft that are mutually spaced apart by an angular space for rotation of the drive shaft with respect to the intermediate element.

摘要： According to an embodiment of this invention, a plurality of stops are implemented between metal surfaces that may be reached only in the event of shocks of great violence and in any case following a certain elastic deformation of the shock absorbing resilient inserts of elastomer, which in any case remains partial compared to full compressing of the elastomer beyond its super elastic limit. At the bottom of each circular cavity (15) housing a respective annular insert (16) of elastomer of the flange (14) of a first cylindrical sleeve (13) directly keyed on the drive shaft of the propeller a hole coaxial and of greater diameter than the diameter of the central hole of the annular insert of elastomer and of the relative engaging pin (19) is formed and the pins projecting from the face of the terminal flange of a second circular sleeve extend through the coaxially formed holes at the bottom of the respective circular cavities of the flange of the first sleeve.

摘要： A variable-pitch propeller, especially for a sport board, has angularly displaceable blade support plates (1) which can be rotated about respective radial axes (2). The plates (1) are provided with radially inwardly directed claws (4) which engage in circumferential grooves (11) of bases (7) of the blades (8). The latter can have radial projections (12) reaching beneath the claws (4). The resulting bayonet connection simplifies mounting and dismounting of the propeller blades (8) even under water.
