Description

Instruction Manual Tubular Air Suspension Platform Technical Field

The invention belongs to the field of flying devices, and in particular relates to a cross flow air suspension platform.

Background technique

There are currently only four ways to achieve vertical takeoff and landing and hovering in the air: A: Jet, B: Screw, C: Flapping, D: Hot Air Balloon and Airship. The above four methods are capable of achieving vertical takeoff and landing and air hovering, but they cannot be effectively applied to flying cars and urban traffic due to both principle and structural problems. Let's take a look at their shortcomings in this respect: A: Jet: The temperature of the jet is too high, the noise is very large and the energy consumption is huge. The above disadvantages can be seen from the British fighter jets. B: Propeller type: The propeller is vertical The best and most successful way of landing and hovering and development, but its shortcomings in urban applications are also significant. The need for increased propeller efficiency results in a very large rotating diameter and high propeller speed. Subtle scratches can cause huge disasters. The huge propellers cannot pass through the narrow streets of the city. Of course, the huge noise is unbearable, and it is impossible to perform emergency braking like a car when there is an emergency in the air. C: Flapping Wing: Many animals have the first to develop a perfect flight structure, and it carries the original dream of human flight, but for thousands of years people have not developed it to carry people to fly, but also because of structural constraints If you need to carry people, then the wings will be too large to fly freely in the city. Hot air balloon and airship type aircraft: Although it can achieve smooth take-off and landing, its volume is even more amazing. It is impossible to walk through small city streets, and it is difficult to adapt to urban life due to slow take-off and landing. Rapid and efficient requirements.

Summary of the invention In order to solve the above technical problems, the present invention provides a cross-flow air suspension platform, which can solve the difficulties encountered by the foregoing four methods in urban flight traffic in a completely new way, and realizes the built-in thrust suspension device. And miniaturization and flattening, the most important thing is that it replaces the chassis driving system of the car and the huge propeller take-off and landing mechanism of the helicopter in a completely new way. It can be said that it is the hovering and taking off and landing of the future helicopter and flying vehicle foundation. Device.

The invention adopts a structure formed by a cross-flow fan and an engine, and the force is used for mutual use, and the principle of the force and the reaction force is utilized, and the counter-thrust obtained by the cross-flow fan to promote the one-way flow of the air is fully utilized, and the platform is realized in the air. Suspended flight device.

The impeller and the outer casing of the cross-flow fan form a structure in which the air moves in one direction, and the impeller of the cross-flow fan rotates at a high speed under the driving of the engine. When the impeller rotates at a high speed, the air is sucked by the impeller, and a thrust is given to the air, and the air is supplied to the impeller. When the force is applied, the air also gives the impeller a counter force to give the fan a lift. The impeller and the engine shaft are arranged in parallel, and can also be installed at right angles through the transmission mechanism and the engine shaft. The cross flow fan is also called a cross flow fan, and the impeller is multi-leaf type, long cylindrical shape, and has a forward multi-wing blade. When the impeller rotates, the airflow enters the cascade from the open end of the impeller, passes through the interior of the impeller, and is discharged into the volute from the other side of the cascade to form a working airflow. The flow of the airflow in the impeller is complex, the velocity field of the airflow is unsteady, and there is a vortex in the impeller, centered near the volute tongue. The existence of the vortex causes a circulating flow at the output end of the impeller. Outside the vortex, the flow line of the airflow in the impeller is arc-shaped. Therefore, the flow velocity at each point on the outer circumference of the impeller is inconsistent. The closer to the vortex core, the greater the velocity, and the closer to the volute, the smaller the velocity. The airflow speed and pressure at the fan outlet are not uniform, so the flow coefficient and pressure coefficient of the fan are average. The position of the vortex has a great influence on the performance of the cross-flow fan. The center of the vortex is close to the inner circumference of the impeller and close to the volute tongue. The performance of the fan is better. When the center of the vortex is far away from the vortex tongue, the area of the circulating flow increases, the efficiency of the fan decreases, and the flow rate does not. The degree of stability increases. The cross-flow fan is mainly composed of three parts: impeller, air duct and electric motor. It has the following characteristics:

1) The axial length is not limited, and the length of the impeller can be arbitrarily selected according to different use requirements;

2) The airflow flows through the impeller and is subjected to the force of the blade twice, so the airflow can reach a very long distance;
