Longitudinal-line-type dual-culvert vertical-lifting air-ground vehicle

Abstract

The invention relates to the field of air-ground dual-dwelling vehicle technology, in particular to a longitudinal-line-type dual-culvert vertical-lifting air-ground vehicle. The vehicle comprises a vehicle body, a driving cabin and vehicle wheels that are arranged on the vehicle body; the front end and the rear end of the vehicle body are respectively provided with a ducted propeller; each ducted propeller comprises a culvert, an airscrew and a bracket; the rotation shaft of the airscrew is arranged vertically; the airscrew is provided with an automatic inclining device; two airscrews are driven to rotate reversely by an engine of the vehicle body; the vehicle can be driven on road by the vehicle wheels and can realize vertical lifting and flying by the lifting force provided by the rotation of two vertical ducted propellers; the flying, landing, suspending, heading, withdrawing and rotating are realized by adjusting the rotation speed difference of the two ducted propellers and/or the elevation of the oars; the controllability is good and the structure is simple; the culverts protect the airscrews and the passerby simultaneously and avoid the passerby from being harmed by the airscrews, thus having high safety performance.

Description

Technical field: [0001] The invention relates to the technical field of land-air amphibious vehicles, in particular to a tandem double-duct vertical take-off and landing land-air vehicle mainly based on road traffic and supplemented by flight. Background technique: [0002] The existing land vehicles are mainly cars, which mainly rely on the wheels to grip and rotate to obtain forward thrust. Therefore, the driving of a car depends on the smoothness of the road. Once the road is congested or damaged, the car will not be able to move forward. , which brings inconvenience to the use of the car. [0003] In order to realize that the car can get rid of the dependence on the ground and lift up and cross obstacles under the above-mentioned situation of being unable to move forward, there are also new vehicles that combine the lift structure of the aircraft, especially the lift system of the helicopter, on the car, such as The Chinese patent application number is 200610082287.2 in...

AI Technical Summary

Problems solved by technology

[0005] The disadvantages of the above-mentioned helicopter flying car are: 1. The lateral balance during the flight after lift-off needs to be maintained by the auxiliary wings deployed, which limits the application of the flying car in narrow spaces such as roadways; 2. 1. The ducted reverse dual-rotors only provide lift, while the level flight and steering actions of the flying car are controlled by each auxiliary wing such as each jet, each rudder and aileron, which makes the structure complicated. There are many parts and high production costs, which increases the risk of mechanical failure of the flying car, reduces the safety of the flying car, and also brings inconvenience to the control of the flying car, so it is not very practical
