6/19/1894: Frederick W. Lanchester Presents Airflow Theory

DALLAS - Today in Aviation, English Polymath and Engineer Frederick W. Lanchester presented his theory of circulatory airflow to the Birmingham Natural History and Philosophical Society in 1894.
The theory would later become pivotal in aerodynamics and modern aerofoil theory.
Lanchester was born on October 23, 1868, in Lewisham, London. After completing his education, Lanchester developed an interest in engineering.
His idea of circulatory airflow was born during a crossing of the Atlantic Ocean. Lanchester studied the herring gulls that followed the ocean liner during the long days at sea. He watched how the birds could fly visually motionless, soaring along up-currents of air. He would measure various birds to understand how the center of gravity contrasted with the center of support.
Once he had returned home, Lanchester began working on his theory of flight, some eleven years before the Wright Brothers took the world’s first successful powered flight. In 1894 he built several models and began to test the theory in his garden in Birmingham, UK.
But disappointment followed. His ideas were immediately discouraged, despite Lanchester’s belief in his aerodynamic hypothesis. He later explained how he was “seriously warned that my profession as an engineer would suffer if I dabbled in a subject that was merely a dream of madmen!”
Lanchester pressed on. He pursued his aeronautical passion while making numerous pioneering developments in the automotive industry, such as the petrol engine. He would later discover the air ‘vortex’ effect from the friction of air moving over the wings and offer the first detailed description of lift and drag.
As aircraft design developed over the years, Lanchester’s contributions were finally recognized. Sadly, this was not before his death on March 8, 1946.

David H. Stringer, the History Editor for AIRWAYS Magazine, has chronicled the story of the commercial aviation industry with his airline history articles that have appeared in AIRWAYS over two decades. Here, for the first time, is a compilation of those articles.
Subjects A through C are presented in this first of three volumes. Covering topics such as the airlines of Alaska at the time of statehood and Canada's regional airlines of the 1960s, the individual histories of such carriers as Allegheny, American, Braniff, and Continental are also included in Volume One.
