Abstract

L'invention appartient au domaine de la construction aéronautique et de la sécurité de navigation aérienne et peut s'utiliser dans des processus d'interaction à impact d'un oiseau avec des éléments structurels d'un avion. L'imitateur d'oiseau destiné à tester les éléments structurels d'aéronefs en cas d'interaction à impact lors de la collision avec un oiseau (la résistance aux oiseaux) se présente comme un projectile dont la masse et la densité moyennes correspondent aux caractéristiques analogues d'un oiseau réel, le projectile comprenant un modèle de squelette et de cavités à l'intérieur d'un oiseau, constitué de billes plastiques creuses ainsi qu'un modèle de tissus musculaires réalisé avec un caoutchouc de siloxane (une silicone). Le projectile peut avoir la forme d'un cylindre dont les bouts rejoignent des hémisphères, la forme d'une sphère, d'un ellipsoïde ou avoir n'importe quelle forme. Cette solution technique permet de reproduire avec exactitude les conditions d'une interaction réelle entre l'imitateur et des éléments structurels d'un aéronef compte tenu de normes sanitaires et hygiéniques relatives à la conduite d'expériences; elle assure également des conditions d'utilisation mieux adaptées.
