Ultra-Long-Range Business Jet With Advanced Composite Wing Architecture

The Falcon 10X is a purpose-built business jet designed for ultra-long-range transcontinental operations, integrating military-grade digital flight control systems and a clean-sheet aerodynamic design. Developed for the high-end corporate and private aviation sectors, the aircraft addresses requirements for increased cabin volume and extended mission range without sacrificing the airfield performance typically associated with smaller airframes.

Aerodynamic Innovation and Composite Structures
The Falcon 10X utilizes a high-aspect-ratio wing constructed entirely from carbon fiber composites. This marks a significant shift in the automotive data ecosystem and aerospace manufacturing transition toward lighter, more rigid materials that reduce total aircraft weight while maintaining structural integrity under high-load maneuvers.

The wing architecture incorporates advanced high-lift devices, specifically slats and flaps, which allow the aircraft to maintain low-speed stability. These features enable the jet to operate from shorter runways that are often inaccessible to aircraft of similar weight classes. The aerodynamic profile supports a maximum operating speed of .925 Mach and a range of 7,500 nautical miles, facilitating direct connections between city pairs such as Los Angeles and Sydney or New York and Shanghai.

Propulsion and Environmental Specifications
Power is provided by two Rolls-Royce Pearl 10X engines, each delivering more than 18,000 lb of thrust. These powerplants utilize the Advance2 engine core, currently cited as a highly efficient core within the business aviation sector. The engine combines a high-performance low-pressure system with specialized cooling and material technologies to reduce noise emissions and fuel consumption.

Internal environmental conditions are regulated to maintain a cabin altitude of 3,000 feet while the aircraft is at a cruising altitude of 41,000 feet. This pressure differential, supported by a 100 percent fresh air exchange system and 38 extra-large windows, is intended to mitigate passenger fatigue during long-duration flights.




Digital Flight Control and Avionics Integration
The NeXus flight deck introduces a third-generation digital flight-control system (DFCS) derived from the Rafale fighter jet. This system integrates a "Smart Throttle" that manages both engines through a single interface, automating complex tasks such as noise-abatement climbs and stabilized go-arounds. According to Eric Trappier, President and CEO of Dassault Aviation, the objective is to allow passengers to experience time on board as a continuation of everyday life rather than an interval between destinations.

Technical safety enhancements include:

Comparative Dimensions and Configuration
The fuselage measures 9 feet, 1 inch (2.77 m) in width and 6 feet, 8 inches (2.03 m) in height. These dimensions exceed the cross-sections of several regional commercial jets, providing 8 inches of additional width compared to established competitors in the ultra-long-range segment. This volume allows for modular cabin zones, including dedicated dining areas, private suites with full-size beds, and optional shower installations.

The Falcon 10X program was officially presented at a dedicated facility in Bordeaux-Mérignac. The aircraft is currently transitioning into a comprehensive flight-test campaign to validate performance data and safety envelopes prior to entry into service.
