Aerodynamic Conclusions Applied - a photo on Flickriver

            In the late thirties many car builders and designers adopted the new theories about car aerodynamics and applied them in the latest car models. These avant-garde plans were not always applied to production models, unfortunately sometimes only single prototypes.

Ideas about car dynamics started early 20th century. In the twenties theories developed and experiments were tried out. But scientific streamline theories were not put into practice on a larger scale until the early thirties.
Early pioneers in Europe in car aerodynamics were for example Paul Jaráy (Austria, 1889-1974), Edmund Rumpler (Austria, 1872-1940), Josef Ganz (Hungary, 1898-1967), Hans Ledwinka (Austria, 1878-1967) and Dennis Burney (UK, 1888-1968). 
Also in France and Italy some mass-produced ultra modern streamlined cars came on the market.
In the US some progressive Chrysler engineers developed the 1934 Airflow, the design of which was years ahead.

This picture shows a visualization of air streams around a mid 1930s streamlined car body. It could be the silhouette of the 1934 Tatra T77, designed by Paul Jaráy in cooperation with engineer Hans Ledwinka. It's clearly visible that the airflow has less resistance and no vacuum is created behind the car.

Picture is taken from the book: G.F. Steinbuch, De Automobiel, Handboek voor autobestuurders, monteurs, reparateurs en technici, deel II Het Chassis, De Carrosserie, Uitg. Kluwer, 1949.
Original photographer/draftsman, place and date unknown.
I found this book in a recycle shop.
