BOAT TAIL FOR TRUCK AND TRUCH WITH THE BOAT TAIL

Boat tail that minimizes air resistance and vibration

This technology is about a truck equipped with a boat tail to reduce air resistance and improve driving stability.

Fuel costs, which account for the largest cost among logistics costs, increase or decrease depending on various conditions, and air resistance has a significant impact on the fuel efficiency of trucks. This technology effectively controls the flow at the rear of the car body, reducing air resistance and flow noise, and aims to provide a boat tail for trucks and a truck equipped with a boat tail that can improve driving stability.

The boat tail using this technology reduces the size and strength of the recirculation area formed at the rear of the car body by controlling the flow separation that occurs at the rear of the vehicle, thereby dramatically increasing driving stability and reducing vibration by reducing the influence of lateral force applied to the truck. The possibility of damage to goods due to vibration during transportation can be minimized.

Key Features:

• The boat tail consists of a straight first end fixed to the rear of the cargo compartment and a second end spaced apart from it and made of a continuous wave.
• Has a curve that gradually increases from the first end toward the second end.
• The continuous waveform of the second end has one of a sinusoidal wave, a triangular continuous wave, and a trapezoidal continuous wave. placed slanted toward the tail

This technology was developed through support from the Korea Transport Institute's research project on air resistance and air vortex reduction devices to reduce fuel during truck operation.
