Driver and Vehicle Simulation

Hexatech six degree-of-freedom driving simulator

The driver is the ultimate non-linear system.  In today's world of simulation this aspect is typically not included as it is very difficult to model driver behavior.  With VIPER's 6 degree of freedom full motion simulator your organization can now put the Driver-in-the-Loop.

  • Train drivers in a low risk, highly flexible environment
  • Evaluate virtual prototypes of vehicles, subsystems, or components
  • Develop stochastic driver models

Engine and Drivetrain

Superflow chassis dynamometer

Located in VIR's north paddock with easy access to the track, VIPER's engine and drive train laboratory is equipped with a Superflow chassis dynamometer and a suite of data acquistion equipment making it an ideal location to develop your power train system.

  • Engine diagnostic and performance testing
  • Engine performance optimization
  • Vehicle data acquistion and analysis
  • At the track vehicle set up services

Aerodynamics

Aerodynamic Development

Leveraging NASA wind tunnels and years of aerodynamic testing expertise, VIPER can assist in the aerodynamic development of nearly any class of vehicle.

  • 14' x 22' rolling road wind tunnel
  • Computational fluid dynamics
  • On track validation
