At its Bordeaux-Mérignac facility in France, Dassault Aviation is completing assembly of the first Falcon 10X, which features the largest cabin cross-section of any purpose-built business jet. Service entry of the 10X is planned for late 2027.

While final assembly of the first article is underway, engineers are conducting airframe load and fatigue limit testing on a mechanical testbed to validate airframe life limits. Like its military cousin, the Rafale, the 10X features a carbon-fiber composite wing.

Falcon 10X systems are being tested on two multi-system test benches at Dassault’s Istres flight test center. Each bench includes subsystems computer suites that represent actual aircraft systems, according to Dassault. “These test benches will verify proper functioning of avionics, engine controls, flight controls, hydraulics, electrical distribution, braking, fire protection and other aircraft systems.” Tests of the flight deck and the digital flight control system are underway at Dassault’s Saint-Cloud headquarters near Paris.

Late last year, Rolls-Royce completed the flight-test campaign for the 10X’s 18,000-pound-thrust Pearl 10X engine. This involved more than 25 flights on Rolls-Royce’s Boeing 747 testbed over six months, including flights to 45,000 feet and at up to Mach 0.90. 

With a cabin that is 6 feet 8 inches tall and 9 feet one inch wide and 7,500-nm range, the 10X will be Dassault’s largest and longest-legged jet.
