The École nationale supérieure d'ingénieurs de constructions aéronautiques, meaning National Higher School of aeronautical constructions, was a French engineering school founded in 1945. It was located in Toulouse.
In 2007, Ensica merged with Supaéro to form the Institut supérieur de l'aéronautique et de l'espace.
Ensica recruited its students from the French "Concours des Grandes Écoles". A competitive examination which requires studies at the "classes préparatoires". Classes préparatoires last two years where students are to work intensively on mathematics and physics.
