Wind Generators (Turbine FAN) [3DRap Feeling PRO]

3DRap offers the opportunity to simulate the wind effect for open-wheel cars, spiders, and vehicles with cooling air inlets in LMP1 and GT endurance configurations. Two custom duct options are available:

• High-Flow: Ideal for simulating the airflow inside the cockpit of enclosed cars, thanks to its high flow rate and larger duct diameter, perfect for endurance and GT cars.
• High-Speed: Designed for open-cockpit cars, reproducing a high-speed airflow relative to the vehicle’s speed, ideal for Formula and Roadster cars.

We have selected high-performance fans to ensure deep immersion:

• Power: 120x38mm fans were chosen to have a good amount of power available;
• Flow: the conveyor was designed through fluid dynamics analysis to maximize the flow rate, the flow speed and the efficiency of the fan, ensuring optimal performance levels for the simulation. A high-quality 3D printing technology was used to maximize the surface finish of the conveyor elements by reducing air resistance.
• Modulation: PWM-controlled fans were chosen, designed specifically for the project specifications; unlike the most common DC continuous power fans, PWM-controlled fans guarantee perfect modulation of the air flow with respect to the speed of the car.
• Installation flexibility: thanks to the double provision for M6 and M8 nuts and the two degrees of freedom of adjustment, it is possible to satisfy every installation requirement.

NOTE: You will need to add an electronics box if you don’t already have one.

Two types of Axial fan can be purchased (same fan, different ducts featured by different targets): "HighFlow" and "HighSpeed". The fluid dynamics of both the ducts and the shape is optimized through the use of neural networks to improve both the maximum flow (HighFlow) and maximum outlet speed (HighSpeed). The HighFlow is the optimal choice to simulate the effect of the wind with regard to the road stock cars as well as for the ducts of the cockpit of the GT cars. In this case, the volume flow rate and efficiency of air flow are the design targets to be optimized. On the other hand, the HighSpeed is the best choice to simulate the wind of Open Wheel cars such as the Formula cars. In this case, the air speed at the outlet is the design target to be optimized.

The PWM fans are engineered exclusively according to 3DRap custom requirements: the fans are featured by very fast dynamics (the change of flow against the change in vehicle speed in the simulator). The dynamics is a very important requirement: indeed, concerning a Formula car, the car go from 300 kph to 0 kph in less than 3 seconds. The 3DRap Wind Simulator allows to match the vehicle speed perfectly. This is possible thanks to the engineering from scratch of the fans and the PWM control of rotor speed which is really fine.
