Description

Hardware platform of oil-powered quadrotor unmanned aerial vehicle

technical field

The utility model relates to an oil-operated four-rotor unmanned aircraft , in particular to a hardware platform of an oil-operated four-rotor unmanned aircraft.

Background technique

The oil-powered quadrotor aircraft is a multi-rotor autonomous aircraft powered by a small aeroengine and capable of vertical take-off and landing. It is a non-coaxial butterfly aircraft in terms of overall layout. Compared with conventional rotor aircraft, its structure is more compact and can generate greater lift, and the four rotors can cancel each other's anti-torque torque without special anti-twist propeller.

At present, there are many kinds of four-rotor and multi-rotor aircraft on the market, all of which use lithium batteries as power sources, brushless motors as power, propellers as the lift system, and a control mode with fixed pitch and variable speed. The multi-rotor of the mode relies on its own gravity and the variable speed of the motor to change the lift force of the propeller for balanced control. The disadvantages are poor maneuverability and weak wind resistance. In addition, due to the restriction of the power-to-weight ratio of the battery, they are all small and micro aircrafts with short battery life and small load capacity. Unable to meet the job task requirements of most customers.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art, and provide an aircraft with the characteristics of long battery life, large load capacity, good maneuverability, strong wind resistance, etc., which can meet the needs of most customers' operating tasks. A hardware platform for an oil-powered quadrotor unmanned aerial vehicle .

A hardware platform for an oil-powered four-rotor unmanned aerial vehicle , including four rotors and an aero-engine, each rotor includes two blades, and each blade is connected to a corresponding hub, and the aero-engine passes through The reduction box transmits the power to the four sets of gearboxes through four transmission shafts arranged in a cross, and then the gearboxes control the two propeller hubs connected to the two rotors through the servo steering gear and the variable pitch system to achieve corresponding movements.

The hardware platform of the oil-driven four-rotor unmanned aerial vehicle of the utility model adopts an aeroengine as power and adds four sets of rotors. In the past, the unmanned aerial vehicles rely on the propeller for lift and the operation depends on the fixed pitch and variable speed mode, which brought about poor maneuverability and weak wind resistance. However, this utility model uses a helicopter rotor mode instead, and the control mode is fixed speed. The variable pitch mode has the advantages of strong wind resistance, large load capacity and good maneuverability.

In summary, the utility model has the following advantages compared with the prior art:

The hardware platform of the oil-driven four-rotor unmanned aerial vehicle of the utility model adopts gasoline/jet fuel as fuel and a small aeroengine as power, the lift system adopts the form of helicopter rotor, and the control mode adopts the mode of constant speed and variable pitch. It has the characteristics of long battery life, large load capacity, good maneuverability and strong wind resistance. It can meet the job task requirements of most customers.
