Patent

CA 2706133

The invention relates to a device for reducing the aerodynamic drag of a vehicle (1) provided with at least one engine (2) including a gas ejection nozzle (3) protruding from the rear of the vehicle fuselage (4) and flaring away from the rear of the vehicle fuselage, characterised in that it comprises at least one member (5) for masking at least a portion of the nozzle, made of a resorptive material (6) that can be eliminated in the nozzle flow once the engine is operating. The invention also relates to a spacecraft including the same.

L'objet de l'invention est un dispositif de réduction de traînée aérodynamique d'un véhicule (1), pourvu d'au moins un moteur (2) muni d'une tuyère (3) d'éjection de gaz dépassant de l'arrière du fuselage (4) du véhicule et s'évasant en s'éloignant de l'arrière du fuselage du véhicule, caractérisé en ce qu'il comporte au moins un élément de masquage (5) d'au moins une partie de la tuyère, en matériau résorbable (6) adapté à s'éliminer dans le flux de la tuyère une fois le moteur allumé et un véhicule spatial le comprenant.
