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.

Diamond Aircraft is exhibiting a mockup of a DA50 single with a 450-shp Motor Sich-Ivchenko AI450S turboprop engine this week at Aero Friedrichshafen 2013 in Germany. This engine would improve the performance of the seven-seat airplane, which was announced in 2006 with a 275-hp diesel engine as the DA50 SuperStar. Since then the SuperStar’s development stalled and it has yet to be certified, even though this milestone was originally planned for mid-2010.


Diamond is testing the market for a short takeoff and landing variant of the DA50 with larger tires, and targeting a takeoff distance of 700 feet. Potential customers are located mainly in Russia and Africa, CEO Christian Dries told AIN. Another possibility would be using conventional tires but increasing cruise speed to 220 or 230 knots, he added.


The Russo-Ukrainian turboprop was chosen for the DA50 Turbine because of its lower price and longer maintenance intervals. In addition, it can operate in a wide range of temperatures, between -55 degrees C and 60 degrees C. The aircraft’s forward fuselage would have to be lengthened to accommodate the exhaust pipe and to maintain the same center of gravity, since the turboprop engine is lighter than the piston powerplant.
