PADA annual design trophy awarded to John Roncz
Every year PADA (Personal Aircraft Design Academy) awards its perpetual trophy to a personal aircraft designer innovator who advanced the state of the art in aircraft performance and efficiency. This year's trophy was awarded to John Roncz whose custom designed airfoils and wings flew two 'round-the-world record airplanes, the Voyager and the GlobalFlyer.

Roncz was also an independent consultant for Scaled Composites and in that capacity provided the detail aerodynamic design (including the wings and stability and control) for the Catbird and the Ares fighter aircraft.

Roncz has also designed several of his own airplanes, including the Genesis - the first successful semi-flying wing sailplane ever built - and the Eagle personal airplane - the first Australian all-composite airplane.

PADA's keynote speaker was Dr. Morton Grosser, a Silicon Valley entrepreneur who was part of the famed Human Powered Aircraft team lead by Dr. Paul MacCready. He was also involved with the 1981 Solar Challenger solar-powered airplane. Dr. Grosser presented the fascinating history of electric powered aircraft pointing out that the first electric powered flight preceded the Wright brothers-an electric powered large airship (hydrogen for buoyancy) flew in France in 1884, powered by an 8.5-hp electric motor.

Dr. Grosser challenged PADA's members to seek highly efficient airplane designs through innovations in battery technology as well as the emerging ultra capacitors. To galvanize the audience he stated that as a venture capitalist, he is involved with start-ups that have prototyped high-efficiency lightweight electric motors and nano technology for tailoring material properties. Dr. Grosser has authored books on human powered flight, inventions that shaped the world and an informative biography of Rudolf Diesel.

John Roncz
John Roncz began his aeronautical career by building a computer and then adapting a NASA airfoil analysis code to run on it. He spent months learning airfoil theory and comparing computer predictions to wind tunnel tests. When Burt Rutan heard of his work he asked John to analyze some airfoil candidates for his Solitaire sailplane. John sent him the results for these along with some of his own airfoil designs for comparison. Burt chose the Roncz airfoil section, which worked very well. This led to a collaboration, which lasted over 20 years, in which Burt developed configurations and John analyzed the stability and designed custom airfoil sections for each airplane.

John is responsible for some portion of 50 aircraft designs. The most recent to fly is the Icon A5, an amphibious Light Sport Aircraft. He was responsible for the aerodynamic design and performance of the GlobalFlyer, a radical jet in which Steve Fossett recently set 3 world records. It was the second airplane John worked on that was placed in the National Air & Space Museum. He has designed 16 propellers and wind turbines, including the propellers for the globe-circling Voyager and the prototype Starship.

Venturing outside the aircraft field, he designed the radical wing-sailed catamaran, which successfully defended the America’s Cup in 1988, and a winning WSC class racecar. John was profiled in Air & Space magazine, published by the Smithsonian. He wrote twelve articles for Sport Aviation, and has guest lectured at eight Universities, including being honored as an “Old Master” by Purdue University.

Among his awards are the Stanley Dzik Memorial Trophy; the Honor Roll of Professional Pilot magazine; the Medal of Achievement from Sailing World magazine; the Professor August Raspet Award; and the Milwaukee School of Engineering Gold Medal. John served as a “Distinguished Lecturer” for the American Institute of Aeronautics and Astronautics. In November 2000 he was honored by His Royal Highness Prince Philip at a ceremony in London, where he was presented with the Prince’s Australian Medal for the design of the Eagle.

John is an honors graduate of the University of Notre Dame, an artist, and a classical pianist. He holds a commercial pilot’s license with multi-engine, instrument and glider ratings and has logged over 1800 hours.
