Bi-directional Splitter for Racing Vehicle Downforce
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerodynamic systems for racing vehicles struggle to effectively generate lift and downforce in real-world racing scenarios, particularly when vehicles are in close proximity to each other, leading to suboptimal performance and control.
Innovation Solution
A bi-directional splitter is attached to the underside of the fore end of a vehicle, featuring multiple surfaces at varying angles to generate both lift and downforce. This splitter adjusts aerodynamic forces based on the vehicle's position relative to other vehicles in traffic, optimizing performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional aerodynamic devices are used to generate downforce, then vehicle grip and control are improved, but the devices are ineffective when vehicles are in close proximity to each other
Solution Approach 1:
The splitter is designed with multiple surfaces at different angles that can dynamically respond to changing airflow conditions. The bi-directional design allows the splitter to adapt its aerodynamic function based on whether air flows from the front or rear, enabling it to maintain effectiveness in both clean air and traffic scenarios without requiring active adjustment mechanisms.
Solution Approach 2:
The invention changes the geometric parameters of the splitter by incorporating multiple surfaces with varying angles relative to the horizontal plane. This allows the device to optimize its aerodynamic performance across different flow conditions and vehicle positions, transforming it from a static component to one that effectively adapts to changing parameters in the racing environment.
2Reliability
If wind deflection devices are used to increase downforce, then vehicle safety and performance are improved, but the devices generate additional drag that reduces attainable speed
Solution Approach 1:
The splitter is segmented into multiple distinct surfaces, each optimized for specific airflow directions and angles of attack. This segmentation allows different portions of the device to handle different aerodynamic functions, reducing overall drag while maintaining downforce generation capability across varying racing conditions.
Solution Approach 2:
Each surface of the splitter is designed with specific local geometric qualities (different angles and orientations) optimized for its particular function. This local optimization ensures that each surface contributes efficiently to downforce generation while minimizing parasitic drag, rather than using a uniform design for the entire device.
3Force
If a trailing vehicle uses traditional aerodynamic devices, then downforce is generated, but significant losses in downforce occur when positioned behind a leading vehicle
Solution Approach 1:
The bi-directional splitter dynamically responds to disrupted airflow from a leading vehicle by utilizing its multiple surfaces at different angles. When air flow from the front is blocked, the rearward-facing surfaces effectively capture the altered airflow pattern, maintaining downforce generation capability in traffic scenarios where traditional devices would fail.
Solution Approach 2:
The splitter converts the harmful effect of disrupted airflow from a leading vehicle into a beneficial aerodynamic condition. By incorporating surfaces oriented to capture rearward-flowing air, the device transforms the turbulent wake behind a leading vehicle into a source of effective downforce, turning the traffic scenario from a disadvantage into an advantage.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The bi-directional splitter significantly enhances downforce generation for a trailing vehicle, improving its performance and control by adjusting aerodynamic forces in response to the vehicle's position relative to a leading vehicle, thereby minimizing losses in downforce experienced by vehicles without this technology.
Implementation Method 1
Based on Bernoulli's principle, lower speed air has a higher pressure than higher speed air, and therefore exerts a greater force on the vehicle. This lower speed air being directed over the vehicle creates downforce on the vehicle.
Implementation Method 2
The aerodynamic devices create downforce by altering high- and low-pressure flows about the body of the vehicle.
