Variable empennage with built-in rotating flexible assembly and design method

Abstract

The invention provides a variable empennage with a built-in rotating flexible assembly and a design method. According to the variable empennage obtained through airfoil design, steering engine parameter selection, airfoil analysis, software data fitting and real vehicle experimental data collection and analysis of the racing vehicle, on a straight road, a driver can control a controller through abutton on a steering wheel to reduce the radian of the upper flexible surface and the lower flexible surface of the empennage so as to reduce air resistance borne by the racing vehicle; and when the racing car turns over or other downward pressure needs to be increased, a driver increases the radians of the upper and lower flexible surfaces of the empennage through the controller to provide the required downward pressure, so that the aerodynamic resistance can be reduced, the aerodynamic performance of the whole car can be improved, a better score can be obtained in a match, and the control performance of the racing car can be improved on a curve. The tail wing system is simple in structure and not prone to failure, the use reliability of the tail wing system and the control stability of the whole racing car are improved, and the aerodynamic performance of the racing car is greatly improved.

Description

technical field [0001] The invention relates to the field of aerodynamics, in particular to a variable empennage with a built-in rotating flexible assembly and a design method thereof. Background technique [0002] In the development of the Formula Student car competition, aerodynamic kits play an important role. In order to improve the competition performance and shorten the time, the team installs a series of aerodynamic kits on the car, which can greatly improve the performance of the car. Performance, among them, in 2010, McLaren used the adjustable tail for the first time in the actual race in F1. In the second year, the FIA ​​agreed to introduce a new body part, which is the adjustable tail. Since then, the adjustable tail has become the aerodynamic kit of the car. important device. The rear wing can provide sufficient downforce to the car to increase the friction with the ground, so that the car can obtain better performance when driving at high speed. When the raci...

But on a straight road, the downforce brought by the rear wing will increase the frictional resistance of the car, causing the car to stall.
