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.

The Tech 800 core engine demonstrator made its first run last month at Turbomeca’s Bordes, France headquarters, the company announced last week. A high-pressure spool for the 1,100-shp engine class, the Tech 800 is a precursor to the engine manufacturer’s TM800 Arrano. The Arrano turboshaft will power the Eurocopter X4 medium twin, a Dauphin successor planned for 2017.


Key Tech 800 technologies are related to “the compressor architecture and performance, the low-emission combustor enabling lower emissions, the turbine operating at a very elevated temperature and a high-efficiency power turbine.” As a result, Turbomeca expects a double-digit improvement in fuel burn, compared with typical efficiency in the year 2000, and quieter operation. Weight should be reduced, too, thanks to the use of composites and titanium aluminide. The control system will use new fuel pumps and electric actuators.


The Tech 800 demonstrator is part of the Clean Sky “joint technology initiative” at the European level. It involves 18 small and medium businesses, as well as 12 universities and laboratories.
