Design Engineering

DEMA has been involved in some of the most important international aeronautical programs, which allowed us to acquire a specific know-how in aeronautic structural design, from the Joint Definition Phase in concurrent with customers. Participation in all phases of an aerospace program has allowed Dema to acquire a unique expertise in the design of fixed wing and rotary aircraft.
