Domina Cleophas Jalbert (born December 5, 1904 in Saint-Michel-des-Saints in Québec , † June 26, 1991 ) was a Canadian aerodynamicist and is considered the inventor of the mattress-shaped surface parachute . By using balloon, parachute, wing and kite features, he succeeded in inventing a rodless, inflated by the wind ( dynamic pressure ) and thus stiff wing with enormous lift force, the parafoil ( paraglider ). In 1964 he applied for a patent for the Parafoil . It made it possible to replace the round-cap parachutes used at the time . The principle is used to construct today's wing parachutes for paragliding , parachuting or kite surfing .

Act

Domina Jalbert was born in Saint-Michel-des-Saints ( Québec ). In his youth, his family moved to Woonsocket, Rhode Island , where he was granted US citizenship. As a pioneer in aviation, he obtained a private pilot's license in 1927 - the 626th American ever. Thanks to his great passion for kites , his own designs soon followed. In 1930, at the beginning of the war, he was hired by the United States Rubber Co. to help build tethered balloons . His first great invention of that time was the Kytoon , a combination of a kite and a balloon . Kytoons were used for creating aerial photographs , installing radio antennas, researching the atmosphere, lifting heavy tree trunks, etc. Jalbert founded the company "Jalbert Aerology Laboratory" in 1949, which was soon involved in the construction of parachutes. During a flight in his Beechcraft aircraft in 1953, Jalbert had the idea of ​​constructing a parachute in the shape of a wing: the parafoil, a flexible wing with open cells that generates lift through the flow of air. After the patent was granted in 1966, the parafoil attracted immediate public interest and was described by some as the greatest advance in parachute design since Leonardo da Vinci .
