International Classification:

B64D 27/00

US Classification:

244 56, 244 124

Abstract:

A tiltrotor aircraft having a wing and a rotatable pylon carried by the wing is disclosed. The pylon is secured to a pylon support spindle that extends into the wing. A link connects a radial portion of the pylon support spindle to a radial portion of an actuator spindle, such that the pylon support spindle is rotated as the actuator spindle is rotated.

International Classification:

G06F 17/50

US Classification:

703 1

Abstract:

Properly identifying the most vulnerable areas and quantifying the effectiveness of armor at those locations is critical to achieving efficient armor integration. A method for designing protective armor for a vehicle includes the deriving shotlines through an element; computing a probability of kill value for each shotline in each element; calculating a probability of kill intensity for each element; ranking the elements according to highest probability of kill intensity; mapping the elements in a 3D CAD environment to visually depict the elements having the highest probability of kill intensity; and designing armor taking into account the elements having the highest probability of kill intensity.

International Classification:

F16F 15/04

US Classification:

2671402

Abstract:

A system and method to control vibrations exerted on a non-vibrating structure. The system includes an adjustable variable stiffness support securely attached to both the non-vibrating structure and a vibrating structure. A driver operably associated with the variable stiffness support is configured to selectively adjust the variable stiffness support. A control system in data communication with both a sensor system and the driver includes an algorithm to determine whether adjustment of the variable stiffness support is required.

International Classification:

B64D 33/02
B64D 27/14

Abstract:

A rotorcraft has a fuselage, an engine disposed substantially laterally centrally relative to the fuselage, and an air intake system (AIS). The AIS has a first duct configured to provide streamline air flow, a second duct configured to provide streamline air flow, and a combining section configured to receive streamline air flow from each of the first duct and the second duct. The combining section is further configured to output streamline air flow.

Bradley Robert Henson - Mansfield TX, US

Assignee:

Bell Helicopter Textron Inc. - Fort Worth TX

International Classification:

B64D 33/02

Abstract:

An air intake system (AIS) has a plenum and an inlet barrier filter associated with the plenum, through which air can selectively enter the plenum. The AIS also has an inlet duct associated with the plenum, through which air can selectively enter the plenum. The AIS also has a bypass door associated with the inlet duct, the bypass door being configured to selectively change an amount of air allowed to pass through the inlet duct. The AIS also has a filter airflow change device configured to change an amount of airflow allowed through the inlet barrier filter.
