Thanks to its Engineering Services department based in the United States, Sonaca Group, through LMI Aerospace, has been involved in the design of the new Aerion supersonic business aircraft since 2016. The market for supersonic jets is currently estimated at about a hundred aircraft per year and constitutes a real development opportunity for the Group. This aircraft will make intensive use of composite materials, one of the company’s strong points. This activity currently focuses on the architecture and installation of systems. The high-level avionics specifications, the distribution of energy, the HIRF (High Intensity Radiated Field) and other systems have been prepared by engineers in the United States. Configuration studies were also carried out on the aircraft, the cabin and the cockpit as well as the allocation of space for the main systems components.
