Study Notes

Formula Bharat 2025

Formula Student Rules

  • Formula Bharat is a student-run competition inspired by the Formula Student UK series
  • Rules are based on the Formula Student UK ruleset with modifications for the Indian context
  • Key rules:
    • Vehicles must be open-wheel, open-cockpit, and powered by an internal combustion engine or electric motor
    • Maximum length: 4.5m, width: 1.8m, height: 1.2m
    • Minimum weight: 250kg (excluding driver)
    • Maximum power: 60kW (80hp)

Vehicle Dynamics

  • Key aspects:
    • Weight distribution: ideal weight distribution is 50:50 (front:rear)
    • Center of gravity (CG): affects handling and stability
    • Suspension:
      • Types: pushrod, pullrod, and inboard-mounted
      • Considerations: camber, toe, and ride height
    • Tire selection: affects grip, handling, and durability

Aerodynamics

  • Key aspects:
    • Drag reduction:
      • Body shape and surface smoothness
      • Airflow management: air dams, splitters, and diffusers
    • Downforce generation:
      • Wings and spoilers
      • Ground effect: venturi tunnels and air curtains
    • Aerodynamic testing: CFD, wind tunnels, and track testing

Electric Powertrain

  • Key aspects:
    • Electric motor types: DC, induction, and permanent magnet
    • Battery selection: energy density, power density, and cooling
    • Motor control unit (MCU): inverter, converter, and control algorithms
    • Electric powertrain advantages: increased efficiency, reduced emissions

Endurance and Efficiency

  • Key aspects:
    • Endurance:
      • Vehicle durability: reliability and maintenance
      • Driver fitness and stamina
    • Efficiency:
      • Energy consumption: electric motor and battery efficiency
      • Aerodynamic efficiency: minimizing drag and maximizing downforce
    • Optimization strategies:
      • Lightweighting: material selection and structural optimization
      • Energy recovery systems (ERS): regenerative braking and kinetic energy harvesting
