John Gregory Roncz (1948-2023) was an inventor, businessman, computer expert, book author, and aerodynamicist.
Roncz designed the sail for the racing yacht Stars and Stripes, which won the 1988 America’s Cup, and worked on Steve Fossett’s Virgin Atlantic GlobalFlyer aircraft,[1] one of around 17 that he worked on with Burt Rutan, including the Voyager, the first aircraft to circumnavigate the world non-stop and without refuelling.[2]
Roncz thoroughly researched airfoils and the aerodynamics thereof, contributing greatly to the modern understanding of airfoil performance. He died September 28, 2023 at the age of 75.
