Abstract
An air inlet device includes an inlet duct, a valve and at least one helical partition positioned within the inlet duct, the helical partition having an outer edge in contact with the inlet duct and delimiting at least one helical duct within the inlet duct. The helical partition serves to increase the distance travelled by an air flow entering the inlet duct before it reaches the valve in the closed state. An aircraft including at least one air inlet device of this kind is disclosed.
Claims10
An aircraft comprising:
- an aerodynamic surface;
- an aircraft system;
- and
- an air inlet device configured to deliver ambient air from outside the aircraft to the aircraft system, the air inlet device comprising:
- an inlet duct comprising and extending between a first end, which opens to atmosphere at an aerodynamic surface, and a second end, through which air is provided to the aircraft system;
- a valve connected to the second end of the inlet duct;
- and
- at least one helical partition that is positioned in the inlet duct and comprises an outer edge in contact with the inlet duct;
- wherein the at least one helical partition delimits at least one helical duct within the inlet duct, such that a distance travelled by an air flow entering the inlet duct is increased;
- and
- wherein the inlet duct and the valve form a cavity when the valve is in a closed state.
