Streamlined vehicle
A streamlined vehicle has a body with low drag . For this purpose, the frontal area and drag coefficient (C w ) are kept as small as possible. The air resistance increases sharply at higher speeds. The lower the air resistance, the lower the driving resistance and fuel consumption, and the higher the top speed.
development
Streamlined vehicles emerged in the 1920s and 30s. Here in were aircraft derived aerodynamic findings implemented. There were streamlined cars (including trucks), streamlined buses , streamlined motorcycles , streamlined locomotives, and streamlined trains . With a few exceptions, the forms developed at that time could not prevail due to their practical disadvantages. In automotive design , the term streamlined shape was used to describe sleek-looking shapes (such as those with a humpback ) with not particularly low air resistance.
Well-known streamlined vehicles are:
- cars
- Rumpler Teardrop Car (1921)
