Embodiment Construction

[0029] Such as figure 1 The schematic diagram of the structure of the Mars rover is shown, including the Magnus rotor 100, the car body 200 and the driving motor 300. The Magnus rotor 100 is arranged horizontally and is rotatably connected to the car body 200. The Magnus rotor 100 is connected to the drive motor 300. The motor 300 is connected in transmission to drive the Magnus rotor 100 to rotate.

[0030] When the Magnus rotor 100 installed horizontally on the car body 200 rotates, it will generate a lift perpendicular to the direction of the air flow under the action of the air flow, and adjust the lift coefficient of the system by adjusting the ratio of the rotor speed to the incoming flow velocity , to increase the flexibility and mobility of the car body, and at the same time combine with the rotor to achieve the effect of the rover's lift and long endurance.

[0031] Design steps include:

[0032] S1: Rotor speed ratio design: based on the load requirements of the Ma...

Abstract

The invention discloses a design method of a Mars rover capable of vertically taking off and landing. According to the method, when a Magnus rotor horizontally arranged on a rover body rotates, the principle that a lifting force vertical to the airflow direction can be generated under the action of airflow is utilized. The design method comprises the steps: 1, designing a rotor speed ratio: simulating the influence of different rotor speed ratios alpha on the aerodynamic characteristics of the Magnus rotor, and obtaining the speed ratio alpha of the Magnus rotor; 2, designing a combined mode of the Magnus rotor: simulating the influence of the combination design of different Magnus rotors on the aerodynamic performance of the Magnus rotors to obtain the combination of a plurality of Magnusrotors; 3, manufacturing a prototype: assembling the Magnus rotor combination mode obtained in the step 2 on a vehicle body to obtain a Mars rover model; and 4, under the simulated Mars environment,determining whether the Mars rover model manufactured in the step 3 can work normally in the Mars atmosphere environment or not, and optimizing the combination mode of the Magnus rotors to obtain thefinal Mars rover.

Description

technical field [0001] The invention relates to the field of aerospace vehicle design, in particular to a design method for a smart Mars rover capable of vertical take-off and landing. Background technique [0002] my country is about to launch a Mars exploration mission in 2020 and realize the Mars rover landing on Mars in 2021. The Mars rover independently developed by our country is about to be able to drive automatically on Mars. However, the terrain on the surface of Mars is complex and unknown, which brings great difficulties to the free movement of the Mars rover. If the rover has a vertical take-off and landing function, it will be able to solve the problem of high-performance movement on the surface of the rover to find the most valuable inspection sites. [0003] At present, the practice of using the Magnus effect to add a rotating body on the wing to increase the lift or only using the rotating body as a device for generating lift has been studied at home and abr...
