    Abstract: A rotor hub fairing system for use in a counter-rotating, coaxial rotary wing aircraft is provided including an upper hub fairing defined about an axis. A lower hub fairing is similarly defined about the axis. An airfoil shaped shaft fairing is disposed between the upper hub fairing and the lower hub fairing. The airfoil shaped shaft fairing has a thickness to chord (t/c) ratio in the range of about 20% and about 45%.

    Abstract: A helicopter and aircraft power device has a plurality of fluid inlets on a windward side of a blade housing and a plurality of fluid outlets on a leeward side in a manner that the fluid inlets communicate with the fluid outlets. The path where the fluid flows in the lengthwise direction on the windward side of the blade housing is far greater than the path where the fluid flows in the widthwise direction on the leeward side of the blade housing, generating a very large pressure difference between the leeward side and the windward side. The action of the centrifugal force and a suction force from a suction motor significantly increase the flowing speed on the windward side of the blade and in the fluid passage, generating bigger pressure difference on either sides of the propeller and thus forming more powerful lift force and driving force.

    Abstract: A system for controlling a magnitude of a sonic boom includes a first sensor configured to detect a first condition of the supersonic aircraft. The system further includes a pair of wings configured to move fore and aft. The system further includes a processor communicatively coupled with the sensor and operatively coupled with the pair of wings. The processor is configured to (1) receive a first information from the first sensor indicative of the first condition, (2) calculate a lift distribution of the supersonic aircraft based on the first information, (3) determine an existence of a deviation of the lift distribution from a desired lift distribution based on the flight condition, and (4) control the pair of wings to move to redistribute the lift in a manner that more closely conforms to the desired lift distribution. The magnitude of the sonic boom is reduced when the deviation is reduced.

    Abstract: A system and method for reducing a velocity deficit from an aerodynamic body is disclosed. An air jet is injected into an ejector mixing chamber in the aerodynamic body. The air jet creates a suction effect in the ejector mixing chamber, which suctions boundary layer air from a perforated surface in at least one side of the aerodynamic body into a plenum chamber and into the ejector mixing chamber. The air jet ejects the boundary layer air and the air jet from a trailing edge slot of the ejector mixing chamber. Suctioning the boundary layer air and ejecting the boundary layer air and the air jet from the trailing edge slot reduces a velocity deficit on a trailing edge of the aerodynamic body. The reduced velocity deficit and the suctioning of boundary layer air reduce noise, turbulence, blade stress, and blade deformation.
