The Falcon 10X, an “augmented” business jet

The business jet niche market is reserved for a small number of companies because of the particularly high technical requirements and the low number of potential customers. Dassault Aviation competes in creativity against its competitors: its youngest, called “Falcon 10X”, in the business jet category, combines very high performance and extreme comfort.

Business jets are used as individual means of transport in lieu of travel on a standard airliner. Jet travel allows great flexibility (since it is the passenger who decides take-off times and the number of stopovers), total confidentiality, arrival at an airport sometimes inaccessible to standard aircraft, unequaled comfort (some jets , like the Falcon 10X, are fitted out like studios, with an equipped kitchen, living room and bedroom with bathroom).

However, this means of transport is inaccessible to ordinary mortals because the Falcon 10X, for example, costs seventy-five million euros to purchase and its annual maintenance is estimated at between six hundred thousand and seven hundred thousand dollars. . And you will have to be patient because it will not be available until 2025.

Some technical characteristics of the Falcon 10X: lightness, resistance and aerodynamics

The wing of the Falcon 10X is made of composite materials, and in particular carbon fiber. This material is as strong as steel, but weighs significantly less. In addition, the shape of this aircraft is optimized with respect to air currents. These three features minimize the aircraft’s fuel consumption as much as possible.

Indeed, an airplane can only take off if the air exerts a vertical force large enough to compensate for the weight of the airplane.

In motion, the aircraft undergoes a force from the air which can be broken down into two components, one in a vertical direction and oriented from bottom to top, called “lift” and the other horizontal direction and in the opposite direction to the movement, called “drag”.

Drag and lift have characteristics that depend, among other things, on the shape of the body and the wings of the aircraft. The fact that the air passing over the upper surface of the wing is bent down implies a variation of a quantity called the “momentum” of the air which, according to the first and third laws of Newtonian mechanics, generates the appearance of lift. This last force must be all the more important as the weight, and therefore the mass, of the aircraft are high.

Furthermore, the drag is more or less important depending on the profile of the wing. An unfavorable profile gives rise to air vortices behind the wing, which strongly brake the aircraft. A favorable profile, on the contrary, will minimize air resistance, and therefore fuel consumption.

In the image below, we can see that the Falcon 10X is optimized from an aerodynamic point of view, since there is almost no vortex in the wake of the aircraft.

Exclusive to the Falcon 10X: combined synthetic vision

This aircraft has very valuable assistance for the pilots: the combined vision system (CVS) allowing them to “see” the landscape when the weather conditions are difficult and/or when it is dark. This system is the result of military research and is embedded in the French combat aircraft, the “Rafale”.

This system is powered by multi-sensor cameras, placed on the front part of the aircraft, which record data simultaneously in visible light and infrared waves (infrared waves are also called heat waves because they are released by hot bodies such as than the human body or the ground and buildings radiating heat at night). These data are merged with images pre-recorded in databases and chosen thanks to the position of the aircraft, to form the landscape that the pilots are supposed to see in normal conditions of visibility.

This synthetic landscape is projected on screens in a high position and at a wide angle, which allows the two pilots to see the same thing simultaneously and therefore to synchronize their actions.

This system has been approved and gives the flight a very high level of safety for passengers.
