Super-miniature fuel oil unmanned helicopter

Abstract

The invention provides a super-miniature fuel oil unmanned helicopter. A propeller connecting structure of the helicopter, particularly a main rotor and a tail rotor, can be innovated, an engine power transfer structure of the fuel oil unmanned helicopter is innovated and improved, a clutch type power output technology and a reduction and differential power transfer structure are introduced, the transmission ratio can be dynamically adjusted according to the rotating speed of an engine, and the power transfer process of the unmanned helicopter is stabilized to the greatest degree. Meanwhile, the structure of the turbo charger of an engine is improved, power of the unmanned helicopter is guaranteed, the power transfer of the engine and the rotating process of a propeller are stabilized under the condition that the engine output power is improved, and conditions are created for reducing the size of the fuel oil unmanned helicopter, so that the super-miniature fuel oil unmanned helicopter of which the body length is 1m or below is innovated at the first time, and the unmanned helicopter has wide market application prospects.

Description

Technical field [0001] The invention relates to the technical field of small unmanned helicopters, in particular to an ultra-micro fuel unmanned helicopter. Background technique [0002] Most of the fuel-fueled unmanned helicopters on the market are more than one meter in length. They are too bulky and difficult to carry. The displacement is above 5CC. The fuel-consuming flight costs are high. The propellers are connected in a traditional way, and the lethality is too large when rotating. If the controller is not paying attention, there will be a fatal danger! In addition, the existing unmanned helicopter does not use clutch power output technology for the engine, and the power transmission performance of the engine is poor, and it does not use a reasonable deceleration differential device to stabilize the power transmission, which makes the flight stability of the existing unmanned helicopter relatively Poor, high stability can only be achieved by increasing the volume of the h...

AI Technical Summary

Problems solved by technology

[0002] Most of the fuel unmanned helicopters currently on the market are more than one meter in length, too large to be carried easily, and the displacement is above 5CC. The cost of fuel-consuming flight is high. The propellers are connected in a traditional way, and the lethality is too great when rotating. There will be fatal danger if the operator is not careful! Also existing unmanned helicopter does not adopt clutch type power output technology to engine, and the power transmission performance of engine is relatively poor, does not adopt reasonable deceleration differential gear stable power transmission, makes the flight stability of existing unmanned helicopter relatively Poor, high stability can only be achieved by increasing the volume of the helicopter, which will cause serious defects such as high flight cost and difficult to carry as mentioned above, which limits the application of unmanned helicopters
