Abstract

The invention relates to a ducted helicopter. The ducted helicopter comprises a driving cockpit. A joy stick is arranged in the driving cockpit. An engine driving belt, a gear box and a drive shaft are arranged on the top of the driving cockpit. The engine driving belt is connected with the drive shaft through the gear box, or each duct is provided with a jet engine. Both sides on the top of the driving cockpit are provided with a pair of the ducts, and each duct is connected with a corresponding end of the drive shaft. Each duct is provided with two layers of blade rotating structures comprising an upper layer and a lower layer. Each blade rotating structure is provided with 2-3 rotating blades, wherein the rotating blades positioned on the upper blade rotating structure and the lower blade rotating structure are arranged staggered. The rotation speed of the rotating blades positioned on the lower blade rotating structure is higher than the rotation speed of the rotating blades positioned on the upper blade rotating structure. The joy stick is provided for adjusting the ducts, and forms closely matching with the rotating blades positioned on the blade rotating structures to control the flight direction angles of the rotating blades in each duct to realize flying forward and backward, flying left and right, turning and air flow adjusting. With the present invention, the design is delicate, the cost is low, the operation is easy, and the service lives of the rotating blades are prolonged.

Description

technical field [0001] The invention relates to the field of aircraft, and more specifically, relates to a ducted helicopter. Background technique [0002] At present, traditional helicopters only have one layer of relatively long blade structure, therefore, the helicopters currently on the market are relatively large in size, and their cost is very expensive. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a ducted helicopter, which has ingenious design, low cost, easy operation and prolongs the service life of its rotor blades. [0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: [0005] A ducted helicopter, which includes a driver's seat, a pair of joysticks are arranged in the driver's seat, and an engine drive belt, a gearbox and a drive shaft are installed on the top of the driver's seat, and the engine drive belt passes through the gearb...
