Airphibian with retractable rotor and control method of airphibian with retractable rotor

Abstract

The invention discloses an airphibian with a retractable rotor and a control method of the airphibian with the retractable rotor. The airphibian comprises an airphibian body, an engine, a rotor module, a variable-collective-pitch module, two front wheels, a horizontal power module and a control module, wherein the rotor module comprises a propeller hub, two propeller blades, a propeller hub spindle, a rotating spindle, a moving ring, a first hydraulic push rod, a second hydraulic push rod, a self-locking ring and at least two self-locking fasteners and is used for making the rotor ascend or descend into a cavity at the upper end of the airphibian body; the variable-collective-pitch module comprises a variable-pitch supporting arm, a variable-pitch motor, a threaded rod and two pull rods and is used for adjusting an inclination angle of the two propeller blades; the horizontal power module comprises two horizontal power units and is used for providing horizontal power during air-ground dual purposes of the airphibian, and each horizontal power unit comprises a ducted fan back wheel, a connecting pipeline, a tee pipe fitting, a folding gear, a folding motor, a drive motor module and a transmission mechanism. The airphibian with the retractable rotor is simple to implement and reliable to operate and has high practical value.

Description

technical field [0001] The invention relates to the field of dual-purpose flying vehicles for land and air, in particular to a dual-purpose flying vehicle for land and air with retractable rotors and a control method thereof. Background technique [0002] There is no doubt that the development of automobile technology has been very mature and advanced. Since the advent of the first airplane, aviation has developed for a whole century. Its safety is the highest among all modes of transportation. The theory of aviation is very mature and advanced. Combining the two is undoubtedly the most perfect choice. Since the first flying car came out in 1917, people have started a lot of exploration of flying cars. Over the years, inventors and flying enthusiasts have designed a variety of flying cars with good performance. Today's urban traffic situation with high-rise buildings and traffic congestion not only makes our daily travel efficiency lower and lower, but even increases the in...

Problems solved by technology

However, for several mainstream flying cars in the world (such as X-Hawk, Airphibian), the power drive for driving on the ground and the lift system in the flight stage are independent. The lift system is either a straight fixed wing with a large wingspan, The disadvantage of this kind of flying car is that it is large in size and cannot be retracted, its shape is fixed, and it is difficult to adapt to the complex traffic conditions in the city.

The second is the large-sized autorotor. This kind of rotor structure is complex to control, and when driving or taking off and landing on the road, it not only affects the normal traffic order, but also the wings are also restricted by roadside obstacles.
