Patent abstract
The present disclosure describes ventilation systems having a reduced aerodynamic footprint. The vents in the ventilation systems are actuated with Shape Memory Alloys that actuate the vents on an as needed basis while effectively sealing the vents when not in operation. The present disclosure further describes a ventilation system in an aircraft nacelle that helps mitigate bowed rotors by cooling down the engine nacelle faster or by helping create a uniform temperature distribution in the nacelle. In various embodiments, the ventilation system comprises vents and fans embedded in the vents.
