Abstract
Technologies for providing noise shielding are described herein. In some examples, noise shields are installed proximate to one or more of the main engines of the aircraft. The noise shields can be extended during terminal operations and retracted during flight operations.
Claims15
A blended wing body aircraft, comprising:
- a fuselage comprising a port wing and a starboard wing continuously coupled to a nose section of the aircraft;
- a first main engine housed within a first nacelle;
- a second main engine housed within a second nacelle adjacent to the first nacelle;
- a first shield panel located proximate to the first nacelle laterally disposed between the first main engine and the port wing, the first shield panel configured to be deployed to reduce at least a portion of noise emanating from the first main engine;
- and
- a second shield panel located proximate to the second nacelle laterally disposed between the second main engine and the starboard wing, the second shield panel configured to be deployed to reduce at least a portion of noise emanating from the second main engine,
- wherein the fuselage further comprises a first cavity to receive the first shield panel when the first shield panel is retracted into the fuselage, and a second cavity to receive the second shield panel when the second shield panel is retracted into the fuselage.

A method of operating a blended wing body aircraft, the method comprising:
- commencing, using a blended wing body aircraft including a fuselage comprising a port wing and a starboard wing continuously coupled to a nose section of the aircraft, terminal operations;
- deploying a shield panel located proximate to a first nacelle laterally disposed between a first main engine and the port wing to shield at least a portion of noise emanating from the first main engine housed within the first nacelle of the aircraft;
- commencing takeoff operations;
- and
- retracting the shield panel, wherein the fuselage comprises a cavity to receive the shield panel when the shield panel is retracted into the fuselage.
