A fsae racing curved air outlet diffuser

Abstract

The invention discloses a FSAE racing car curved surface air outlet diffuser, comprising a guiding object, an air suction portion, a central channel, a transition plate, and an air outlet portion. The guiding object is in a triangular wedge structure, and the height of the front end of the guiding object is higher than the height on the rear end, and width of the front end is smaller than the width on the rear end, and two sides of the guiding object are concave guiding curved surfaces. The air suction portion is a curved plate, and the width on the front end is larger than the width on the rear end, and the included angle between the front end and a horizontal plane is smaller than the included angle between the rear end and the horizontal plane. The width on the front end of the air suction portion is larger than the width on the rear end of the guiding object. The central channel is a frame formed by four flat plates. The transition plate is a smooth curved plate arranged in an inclined manner, and the inclination angle on the front end of the transition plate is consistent with the inclination angle of the tail part of the central channel, and the inclination angle on the rear end is consistent with the inclination angle of the air inlet of the air outlet portion. The air outlet portion comprises two air outlet units, and each air outlet unit is in a horn structure. The FSAE racing car curved surface air outlet diffuser can increase down force of a FSAE racing car, so that the racing car obtains preferably good ground adhesive force.

Description

technical field [0001] The invention belongs to the field of automobiles, and in particular relates to a diffuser for an FSAE race car curved surface air outlet. Background technique [0002] In recent years, the Formula Student Automobile Competition (FSAE racing car) has developed rapidly around the world with its openness and original design. With the continuous improvement of the competition level, the racing engine and chassis technology are becoming more and more mature, and the racing car designers are seeking higher breakthroughs from the excellent aerodynamic technology. Aerodynamic characteristics have an important impact on the performance of FSAE racing cars in all aspects. Among them, the aerodynamic drag coefficient and the negative lift coefficient are two key parameters to measure the aerodynamic characteristics of the racing car. The aerodynamic drag coefficient ensures that the car has high-speed driving performance, and the negative lift coefficient meas...

AI Technical Summary

Problems solved by technology

For an FSAE racing car without a diffuser, when the speed of the racing car increases, the adhesion of the whole car will decrease, resulting in insufficient grip of the rear wheels and skidding; when entering a corner at high speed, the car will skid and become difficult to control

In the end, it will not only affect the performance of the race, but also cause a great safety hazard to the driver and the car

[0003] At present, most teams use air outlet diffusers with flat curved surfaces. Due to the small change in the curvature of the curved surface, it is difficult to effectively use part of the gap between the rear of the diffuser and the chassis, so the downforce generated is small and the adhesion of the tires is low. Poor, poor cornering performance
