Paul F. Bikle (June 5, 1916 – January 19, 1991) was director of the U.S. National Aeronautics and Space Administration (NASA) Dryden Flight Research Facility from 1959 until 1971, and author of more than 40 technical publications.

In 1947 Bikle was appointed Chief of the Performance Engineering Branch, and directed tests of the XB-43 Jetmaster, the first U.S. jet bomber; the Convair XC-99, and the North American F-86A Sabre.

In July 1962 he was awarded the NASA Medal for Outstanding Leadership for his part in directing flight operations and research activities on the highly successful rocket-powered X-15 program.

Just before Christmas 1961 Paul Bikle gave a directive to Charles Richard to quickly and cheaply design and build what would become the template for the Rogallo wing used for a high percentage of modern hang gliders.

Paul Bikle's directive synergistically birthed a wing that would dramatically change personal aviation in powered and un-powered forms.
