Dassault’s big secret

The Dassault SMS has been one of the industry’s best-kept secrets for several years. At NBAA in Las Vegas last week, the French airframer finally revealed the long-range jet it has been working on behind closed doors as the 5X, an aircraft         with the widest fuselage ever designed for a purpose-built business jet. Flight International’s 29 October issue not only has a full technical description detailing how Dassault has designed the aircraft and what suppliers are on board, but also an exclusive cutaway poster.

As well as a six-page report on the biggest business aviation convention in the world, this week’s issue also has a flight test, by Mike Gerzanics, of the Bombardier Learjet 75 and a feature package on military engines; we look at Rolls-Royce’s plans to roll out the fifth major upgrade to its T56 turboprop engine, and at prospects for another venerable powerplant, the General Electric GE38.

In news: Airbus studies the possibility of a further stretch of the A350 and the mixed fortunes of two Boeing programmes, as the slow-selling 747-8 makes way in the Everett facility to the in-demand 787.
