Vortex generators

Types of Vortex Generators

Vortex generators are aerodynamic components that are used on vehicles to control or manipulate the flow of air. They are often found on various vehicles such as trucks, cars, and aircraft. Car vortex generators come in different types, each designed for a specific purpose. They include the following:

• Delta wing vortex generators: Delta wing vortex generators are used on delta wing aircraft. They help improve the control of airflow over the wing of the aircraft. This, in turn, helps to increase the aircraft's performance, especially during take-off and landing.
• Extended vortex generators: Extended vortex generators are an advanced form of vortex generators that are larger in size. They are designed to provide additional control over airflow separation. They are used in the rear portion of vehicles and are common in high-performance cars and trucks.
• Micro vortex generators: These vortex generators are small in size and are designed to control the flow of air around specific parts of a vehicle. They are commonly used on the surface of vehicles like the hood or the roof.
• Sawtooth vortex generators: Sawtooth vortex generators are designed with a sawtooth shape. This design helps in the control of airflow separation. They are used on the rear part of vehicles such as trailers and trucks. Sawtooth vortex generators help in reducing drag and improving vehicle stability.
• Inclined vortex generators: Inclined vortex generators have an inclined angle that is designed to manipulate airflow in a specific direction on vehicles. They can be inclined in different ways depending on the desired effect. Inclined vortex generators are used in motorsports to increase the downforce of a vehicle.
• Curved vortex generators: Curved vortex generators are designed with a curved shape. This helps to improve the efficiency of controlling airflow separation. They are mostly used in aircraft and certain vehicles to improve aerodynamics.
