A jet noise suppressor including a nozzle having a front end and an opposed rear end, spokes extending radially inward from the nozzle, the spokes defining vents, and a center-body connected to the spokes and in fluid communication with the vents, the center-body being positioned centrally within the nozzle and including a closed front end and an open rear end, wherein the front end of the nozzle entrains a first ambient airflow passing through the nozzle and exiting the rear end of the nozzle proximate a periphery of the nozzle, and wherein the vents entrain a second ambient airflow passing through the center-body and exiting the rear end of the nozzle proximate a center of the nozzle.

Jet airplane configuration

An integrated and/or modular high-speed aircraft and method of design and manufacture. The aircraft can have a supersonic or near-sonic cruise Mach number. In one embodiment, the aircraft can include an aft body integrated with a delta wing and a rearwardly tapering fuselage to define a smooth forward-to-rear area distribution. A propulsion system, including an engine, inlet, and exhaust nozzle can be integrated into the aft body to be at least partially hidden behind the wing. In one embodiment, the entrance of the inlet can be positioned beneath the wing, and the exit of the nozzle can be positioned at or above the wing. An S-shaped inlet duct can deliver air to the aft-mounted, integrated engine. The aircraft can include aft-mounted elevators, wing-mounted elevons, and forward-mounted canards for pitch control. The construction of the aircraft can be modular to take advantage of commonalties between near-sonic and supersonic structures.

Integrated and/or modular high-speed aircraft

Methods and apparatuses for installing and actuating movable airfoils, such as canards. A canard in one embodiment of the invention includes an airfoil positioned external to an aircraft fuselage. The airfoil can include a first portion and a second portion (such as a flight control surface) movable relative to the first portion. A connecting portion depends from the airfoil portion and has an attachment portion configured to attach to an aircraft internal to the aircraft fuselage. A connecting portion can include first and second load paths to carry corresponding first and second load portions between the airfoil portion and the attachment portion. The connecting portion can be rotatable about a rotation axis positioned between the first and second loads paths. Accordingly, the connecting portion can be relatively compact so as to reduce the impact of the connecting portion and the volume of the fuselage.

Method and apparatus for installing and actuating movable airfoils, including canards

Integrated high-speed aircraft, such as high-speed transport aircraft, and associated methods of manufacture. In one embodiment, a high-speed transport aircraft includes a fuselage having a first fuselage portion and a second fuselage portion positioned aft of the first fuselage portion. The first fuselage portion can have a first cross-sectional area and the second fuselage portion can have a second cross-sectional area that is less than the first cross-sectional area. The high-speed transport aircraft can further include a wing and a propulsion system. The wing can extend outwardly from the fuselage at least proximate to the second fuselage portion and can include a leading edge region and a trailing edge region. The propulsion system can include an engine nacelle fixedly attached to the wing and laterally aligned with the second fuselage portion. In one aspect of this embodiment, the engine nacelle can include an air inlet positioned aft of the leading edge region of the wing and an exhaust gas outlet positioned aft of the trailing edge region of the wing.
