Embodiment Construction

[0026] In order to make the purpose, content and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] Such as figure 1 As shown, the present invention proposes a vector thrust ducted propeller with an adjustable inlet and outlet grille, which includes a ducted housing 1, an inlet adjustable grille 2, an outlet adjustable grille 3, an inlet grille frame ring 4, Exit grid frame ring 5, variable pitch propeller blade 6, propeller hub 7;

[0028] The imported adjustable grille 2 is made up of a plurality of grille blades, the grille blades are symmetrical airfoil structures, the distance between adjacent grille blades is about the chord length of the grille blades, and all the grille blades pass through the rotating shaft 8 (such as image 3 shown) is fixed on the inlet grill ring 4; similarly, the outlet adjustable...

Abstract

The invention provides a vector thrust ducted propeller with inlet and outlet adjustable grids. The vector thrust ducted propeller comprises a ducted shell (1), an inlet grid (2), an outlet grid (3),an inlet grid frame ring (4) and an outlet grid frame ring (5). The inlet grid (2) is composed of a plurality of grid blades, each grid blade is of a symmetrical wing-shaped structure, the distance between every two adjacent grid blades is the chord length of the corresponding grid blade, and all the grid blades are installed on the inlet grid frame ring (4) in parallel through rotating shafts; the outlet grid (3) is the same structure as the inlet grid (2) and is arranged on the outlet grid frame ring (5) through a rotating shaft; and the inlet grid frame ring (4) and the outlet grid frame ring (5) are respectively fixed at an inlet and an outlet of the ducted shell (1). A complex periodic variable pitch mechanism on a traditional propeller is omitted, the structure is simple, the weightis light, and the reliability is improved. The angle of the duct inlet adjustable grid, the angle of the duct outlet grid and the total pitch of the propeller can be controlled.

Description

technical field [0001] The invention belongs to the field of aviation, and in particular relates to a vector thrust ducted propeller with an inlet and outlet adjustable grille, which is used for ducted propeller-type aircraft with vertical take-off and landing functions. Background technique [0002] Vertical take-off and landing aircraft generally use propellers or rotors to generate lift to balance the weight of the aircraft. A common vertical take-off and landing aircraft is a helicopter, which uses a large-sized rotor installed above the aircraft to provide lift; another common vertical take-off and landing aircraft is a multi-rotor UAV, which uses multiple smaller-sized propellers to provide lift; There is a vertical take-off and landing aircraft that installs a propeller with a smaller size in an annular duct to provide additional lift, protect the propeller and reduce noise. [0003] At present, the control difficulty of VTOL aircraft is generally greater than that o...
