Civilian F1 Front Wing System: "Embedded Wing" Final Complete Solution

Version: V2.0 (Final Draft)

1. Project Background & Objectives

1.1 Problem Definition

Civilian vehicles at 120–180 km/h (75–112 mph) face three core aerodynamic challenges:

1.2 Solution

Borrowing the core "Outwash & Wake Management" logic from F1 front wings, we use Recessed Ducts and Side Intake Canards to forcibly push front tire turbulence outward, while generating auxiliary downforce to improve high-speed stability.

1.3 Design Constraints

• Ground Clearance: 9–12 cm (accommodating speed bumps, garage seams, potholes)
• Pedestrian Safety: Compliant with ECE R127 / GB/T 24550 regulations
• Cost: Mass production cost ≤1,100 CNY/set
• Aesthetics: Integrated with bodywork, no exposed sharp structures

2. Core Design Philosophy

2.1 "Dimensional Reduction" from F1 to Civilian

F1 front wings are designed for 300 km/h, 10 cm ground clearance, carbon fiber monocoque, and slick tires. Civilian vehicles operate at 120–180 km/h, with 15–25 cm ground clearance and steel/aluminum closed body structures.

Directly copying F1 front wings = disaster.

The correct approach: Extract the "Outwash & Wake Management" core logic from F1 front wings, and reimplement it with civilian materials and processes.

2.2 Front Wing Function Weighting

2.3 The True Advantage of Multi-Element Wings

The core advantage of multi-element wings is not "higher lift coefficient," but "higher vortex control precision."

• Each small element's tip generates a Tip Vortex
• Multiple small elements = multiple tip vortices = multiple controllable helical airflow streams
• These vortices superimpose in the spanwise direction, forming a powerful Outwash airflow "fan"
• The more small elements, the more precisely engineers can "sculpt" each vortex's position, strength, and direction

3. Structural Solution: "Embedded Wing" System

3.1 Front Splitter — Integrated Design

• Integrated with the front bumper, not an independent floating wing
• Ground Clearance: 9–12 cm
• Lower Edge: Fitted with replaceable UHMWPE (Ultra-High Molecular Weight Polyethylene) anti-scrape strips
  • Thickness 5 mm, width 30 mm
  • UHMWPE has extremely low friction coefficient (0.1–0.2), slides over speed bumps and garage seams without scraping
  • Clip-on fixation, replaceable when worn, cost only 50 CNY/strip
• Internal: Duct channels guide airflow under the vehicle
• Material: GRP (Glass Reinforced Plastic), 3 mm thickness
• Support Structure: Elastic aluminum alloy brackets allow the splitter to float 3–5 mm vertically on rough roads, avoiding rigid impact

3.2 Recessed Ducts — Outwash Core

• Location: Inside the front bumper
• Quantity: 2–3 duct channels
• Function:
  • Inlet at the front bumper leading edge, collecting front tire turbulence
  • Internal guide vanes (embedded, not exposed) direct airflow outward
  • Outlet on the side of the front bumper, generating Outwash effect
• Material: PA66+GF30 (Nylon 66 + 30% Glass Fiber), injection molded
• Edge Radius: R≥2.5 mm
• Guide Vane Angles: Upper vanes 5°–8°, lower vanes 3°–5° (static, no moving parts)

3.3 Side Intake Canards — Secondary Guidance

• Location: Vehicle side (sidepod area)
• Function:
  • Integrated with body side, not exposed
  • Further guide front tire turbulence outward
  • Protect sidepod intakes and underbody diffuser
• Material: PA66+GF30 (Nylon 66 + 30% Glass Fiber), injection molded + OEM paint/matte texture coating
• Edge Radius: R≥2.5 mm

3.4 Breakaway Clips — Pedestrian Protection

• Location: Connections between splitter, recessed ducts, side intake canards, and body
• Function: Clips actively detach under 150 kg impact, preventing secondary injury to pedestrians
• Material: PA66+GF30, designed breaking force of 150 kg

4. Ground Clearance & Anti-Scrape Design

4.1 Ground Clearance Parameters

4.2 Anti-Scrape Design

• UHMWPE Anti-Scrapes Strips:
  • Extremely low friction coefficient (0.1–0.2), slides over speed bumps and garage seams without scraping
  • Clip-on fixation, replaceable when worn, cost only 50 CNY/strip
• Elastic Support Structure:
  • Elastic aluminum alloy brackets allow splitter to float 3–5 mm vertically on rough roads
  • Avoids rigid impact, protects splitter structure

5. Pedestrian Safety Compliance

5.1 Regulatory Requirements

• ECE R127 / GB/T 24550: Civilian vehicle front bumpers must not have protruding, floating, or sharp small forward-extending wing elements
• Edge Radius: All exposed edges must have radius R≥2.5 mm
• Breakaway Clips: Must actively detach under 150 kg impact

5.2 Design Implementation

• Embedded Design: Wing functions achieved through recessed ducts, minimizing exposed sharp structures
• Edge Radius: All exposed edges have radius R≥2.5 mm
• Breakaway Clips: Actively detach under 150 kg impact, preventing secondary injury to pedestrians
