Roundel

The Tricolore cockade of the French Air Force was first used on military aircraft before the First World War[1]

A roundel is a circular disc used as a symbol. The term is used in heraldry, but also commonly used to refer to a type of national insignia used on military aircraft, generally circular in shape and usually comprising concentric rings of different colours. Other symbols also often use round shapes.
