Thierry Dubois is a freelance writer specializing in helicopters, business aviation and aerospace technology. He earned a degree in fluid dynamics from an engineering school in Toulouse, France in the mid-1990s. At an unexpected crossroads, he found his first job in journalism. In 1997, he started working for French aerospace weekly Air &amp; Cosmos in Paris. This lasted until 2000, when he moved south to Lyons. He then became a freelancer, working for various aerospace publications and has been part of the AIN team since late 2000. In addition to writing about business aviation, Thierry shares responsibility for the rotorcraft section. He also is a regular on-site writer for AIN’s daily editions at international airshows such as the Paris, Farnborough, Dubai and Singapore shows, as well as at EBACE in Geneva.
In 2007, he won the Honeywell award for “Best systems or technology submission” at the Aerospace journalist of the year awards. In 2013, he won an Aerospace Media Award for the "Best Safety, Training &amp; Simulation Submission."
In other activities, Thierry moderates international conferences on aviation technology topics. Thierry is married and has three children, who seem to begin enjoying the mountains–as their parents do.

Sikorsky’s X2 compound helicopter reached another milestone last month by completing two test flights that included full engagement of the high-speed tail propulsor for the first time. In one hour of testing conducted during the two flights, the aircraft flew at speeds up to 52 knots in one test and 42 knots with the propeller providing forward thrust in the second flight. The demonstrator aircraft is designed to reach 250 knots, about twice as fast as current helicopters. The stability augmentation system operated as designed, and vibration and noise levels were very low. The X2 made its first flight in August last year, though using only its contra-rotating coaxial rotors; the propulsor has been undergoing ground testing since January 23. The aircraft will relocate to the company’s flight-test center in West Palm Beach, Fla., by month’s end for continued test flights leading up to the 250-knot goal.
