Application: Propulsion system for an aircraft (Patent ID: US20240084761A1)
The invention by Safran SA is a propulsion system for aircraft that includes a rotor and a nacelle fairing made of deformable shape memory material. The downstream section of the fairing has pneumatic or hydraulic actuators that can deform radially under control pressure. The actuators are toroidal in shape and can be made of stiffened elastic material or include bladders encased in spiral springs with inlet valves.
The system also includes stiffening bridges, an intermediate section connecting the upstream and downstream sections, and can be mounted on an aircraft to pivot using a pivot shaft. The design allows for controlled deformation of the fairing to optimize aerodynamic performance. The patent claims cover various configurations of the actuators, including semi-toroidal shapes, and the use of solenoid valves for control. The system aims to improve the efficiency and performance of aircraft propulsion systems through innovative design and materials.
