CA 2641078

A missile (10) includes a radome-seeker airframe assembly (12) that has a single-piece composite material forebody (11 ). The forebody is made of a high- temperature composite material that can withstand heat with little or no ablation. The forebody has a front part (26) with an ogive shape and an aft part (28) that has a cylindrical shape. The front part acts as a radome for a seeker located within the forebody. Patch antennas (52, 54) are attached to an inside surface of the cylindrical aft part. The aft part acts as a radome for the patch antennas, allowing signals to be sent and received by the patch antennas without a need for cutouts. A single seal may be used to seal the guidance system and seeker within the forebody, allowing the equipment to be hermetically sealed within the forebody.

L'invention concerne un missile (10) comprenant un ensemble cellule (12) qui comporte une ogive (11) monobloc constituée d'un matériau composite servant de radôme à une tête chercheuse. L'ogive est constituée d'un matériau composite haute température pouvant résister à la chaleur avec une ablation réduite ou sans ablation. Cette ogive comprend une partie antérieure (26) de forme ogivale et une partie postérieure (28) de forme cylindrique. La partie antérieure sert de radôme pour une tête chercheuse se trouvant dans l'ogive. Des antennes à plaques (52) sont fixées sur une surface interne de la partie postérieure cylindrique, ce qui permet auxdites antennes à plaques d'envoyer et de recevoir des signaux sans coupures nécessaires. Un joint unique peut être utilisé pour étanchéifier hermétiquement le système de guidage et la tête chercheuse dans l'ogive.
