Abstract: Ventilation systems and methods for controlling moisture in a vehicle. The ventilation systems include one or more inlet ducts and outlet ducts that extend through an inner wall and into a gap formed at an outer wall. The ventilation systems provide for passive air flow with air moving into the one or more inlet ducts and into the gap. The air is cooled against the outer wall and vertically drops along the gap. Moisture in the air freezes against the outer wall while the air is in the gap. The less humid air then moves through the one or more outlet ducts and back into the interior space.

Abstract: Aircraft and air scoop systems are provided. An aircraft includes an interior compartment, an outer skin, an air scoop, a movable element, and a passive pneumatic actuator. The interior compartment encloses a substantially constant interior air mass at a cabin pressure during flight and the outer skin at least partially defines a ventilated cavity. The air scoop is disposed on the outer skin and communicates air between the ventilated cavity and an external environment in which the aircraft is located. The movable element is movable between an open position and a closed position over the air scoop to define an air flow area through the air scoop. The passive pneumatic actuator is operatively coupled with the movable element and moves the movable element towards the closed position in response to an increasing altitude of the aircraft based on a differential pressure between the interior air mass and the external environment.

Abstract: A propulsion engine for an aeronautical vehicle defines a radial direction and a cooling air flowpath. The propulsion engine includes a power source; and a fan including a fan blade rotatable by the power source and extending generally along the radial direction, the fan blade defining an inlet, an outlet, and a cooling air passage extending between the inlet and the outlet and in airflow communication with the cooling air flowpath, the inlet being positioned inward from the outlet along the radial direction to provide a cooling airflow through the cooling air flowpath.

Abstract: A passenger cabin air distribution system includes a ventilation system and an ejector-diffuser. The ventilation system is operable to provide a conditioned air. The ejector-diffuser is positioned to receive a flow of the conditioned air from the ventilation system. The ejector-diffuser includes an induction unit and a diffuser section. The induction unit includes a secondary inlet in communication with a cabin air from a passenger cabin and is configured to mix the flow of the conditioned air with an induced flow of the cabin air into a mixed air. The diffuser section includes a discharge to eject the mixed air to the passenger cabin. The diffuser section is shaped to provide for efficient mixing with low backpressure in order to maintain the low motive pressure in the nozzle.

Abstract: In a method for the ventilation of an aircraft area, air conveyed from an aircraft environment by a conveying device into an interior space of the aircraft is supplied during ground operation of the aircraft to the aircraft area to be ventilated. During flight mode of the aircraft, air flowing from the aircraft environment via a ram air duct into the interior space of the aircraft is supplied to the aircraft area to be ventilated. During flight mode of the aircraft, in addition to the air flowing from the aircraft environment via the ram air duct into the interior space of the aircraft, air conveyed from the aircraft environment by the conveying device into the interior space of the aircraft is supplied to the aircraft area to be ventilated when a flight velocity of the aircraft falls below a flight velocity threshold value.
