What is a Kammback car?
The term “Kammback” refers to an automotive body style with a roofline that tapers downward toward the car’s rear before being cut off abruptly. Early studies found that a car with a teardrop shape yielded the best aerodynamics, but it necessitated a body that was impractically long.
What is called Kamm effect?
A Kammback—also known as “Kamm tail” or “K-tail”—is an automotive styling feature. The rear of the car slopes downwards before abruptly cutting off with a vertical surface. A Kammback minimizes aerodynamic drag while maintaining a practical shape for a vehicle.
Why is a teardrop aerodynamic?
For speeds lower than the speed of sound, the most aerodynamically efficient shape is the teardrop. The teardrop has a rounded nose that tapers as it moves backward, forming a narrow, yet rounded tail, which gradually brings the air around the object back together instead of creating eddy currents.
What is the tail of a car called?
Spoiler (car) – Wikipedia.
What are the tails on cars called?
A spoiler is an automotive aerodynamic device whose intended design function is to ‘spoil’ unfavorable air movement across a body of a vehicle in motion, usually described as turbulence or drag. Spoilers on the front of a vehicle are often called air dams.
Why is the rear of a car called a Kammback?
The rear of the car slopes downwards before abruptly cutting off with a vertical surface. A Kammback minimizes aerodynamic drag while maintaining a practical shape for a vehicle. The Kammback is named after German aero-dynamicist Wunibald Kamm for his work developing the design in the 1930s.
Why was the Kamm tail important to sports cars?
The Kamm tail presented a partial solution to the problem of aerodynamic lift, which was becoming severe as sports car racing speeds increased during the 1950s.
How did Kamm come up with the design of Kammback?
Kamm’s design is based on the tail being truncated at the point where the cross section area is 50% of the car’s maximum cross-section, which Kamm found represented a good compromise—by that point the turbulence typical of flat-back vehicles had been mostly eliminated at typical speeds.
What kind of car did Wunibald Kamm make?
German Professor, Wunibald Kamm worked with aerodynamics engineer Baron Reinhard von Koenig-Fachsenfeld. They developed a design with a smooth roofline and a taper in the automobile’s body that is suddenly chopped off at the rear end.
