Title
(EN) PYROTECHNIC WHEEL ACCELERATION SYSTEM
(FR) SYSTÈME PYROTECHNIQUE D'ACCÉLÉRATION DE ROUE
Abstract
(EN) Wheel acceleration systems are disclosed that provide a motive force to at least one wheel of an aircraft, in order to accelerate the aircraft to takeoff speed with the assistance of main engine thrust. The wheel acceleration system includes a pyrotechnic unit configured to generate expanding gases by combusting a propellant, and a rotary propulsion unit pneumatically coupled to the pyrotechnic unit. The rotary propulsion unit includes an impeller configured to be driven by the expanding gases and to deliver torque to the wheel.
(FR) Sont divulgués des systèmes d'accélération de roue qui fournissent une force motrice à au moins une roue d'un aéronef, pour permettre l'accélération de l'aéronef jusqu'à une vitesse de décollage à l'aide de la poussée du moteur principal. Le système d'accélération de roue comprend une unité pyrotechnique conçue pour générer des gaz en expansion par combustion d'un agent propulseur, et une unité de propulsion rotative accouplée pneumatiquement à l'unité pyrotechnique. L'unité de propulsion rotative comprend une roue à aubes conçue pour être entraînée par les gaz en expansion et pour fournir un couple à la roue.
