Abstract: A control system having a first loop configured to provide a longitudinal blowback value of a rotor blade during flight and a second loop associated with the first loop, the second loop being configured to provide a design maximum total flapping value and a lateral flapping value. A method includes calculating a flight control limit from the design maximum total flapping value and the lateral flapping value. An upper longitudinal cyclic control limit is calculated by adding the flight control limit to the longitudinal blowback value. A lower longitudinal cyclic control limit is calculated by subtracting the flight control limit from the longitudinal blowback value.

Abstract: Disclosed is an aircraft door including a handle-activated pressure relief system that avoids potentially dangerous pressure differences between the cabin and the atmosphere outside the aircraft. A flow path is created between the inboard and outboard handles on the door. A pressure vent door is located in the flow path. The vent door being is opened when either of the inboard and outboard handle assemblies are activated. Once either handle is rotated beyond a particular point, a spring in the supporting mechanics becomes over-center. At the same time, the vent door comes under the influence of a magnet, snapping the vent open. After the door has been opened, it can be relatched by operating the handles in the reverse direction. The magnet and spring hold the vent door open until the aircraft door is fully latched, sealed, and secured. Only then does the vent door sealingly close.

Abstract: A compression-molded part has a conductive layer embedded in the part during molding of the part. The conductive layer is generally adjacent an outer surface of the part and is preferably formed from a mesh, a foil, a pulled screen, or multiple layers of conductive elements. The part is preferably optimized for use on the exterior of an aircraft for lightning-strike or EMI protection or for use as an antenna. Methods for forming the panels of the invention include placing the conductive layer against a mold surface of a compression mold, then forming the compression-molded part with the conductive layer embedded in the part.

Abstract: The invention relates to a method for producing hollow bodies from thermoplastic material, comprising the molding of at least two sheet-like, web-shaped preforms of plasticated thermoplastic material in a multi-part tool forming a cavity to form two complementary shells, and also the joining together of the shells to form a substantially closed hollow body, wherein the preforms are brought between open parts of the tool which each have part-cavities, the parts of the tool are then closed against a tool separator arranged between the preforms, and the preforms are inserted into the part-cavities with the use of differential pressure and molded. In a subsequent separate method step, the tools are reopened and internal components of the hollow body to be produced are fastened to the shells. Finally, the shells are joined together by reclosing the tools to form a closed hollow body.

Abstract: A vibration isolator is disclosed having a housing which defines a fluid chamber. A piston, which is movable to and from a down position, is disposed within the housing. A vibration isolation fluid is disposed within the fluid chamber. A passage having a predetermined diameter extends through the piston to permit the vibration isolation fluid to flow from one fluid chamber to the other. An elastic element is provided for reducing transmission of vibrations from the piston to the housing when the piston is at the down position.

Abstract: An air/ground contact logic management system for use with fly-by-wire control systems in an aircraft. The system includes a first sensor configured to provide an output signal to determine when the aircraft is in a transition region. A logic management system is in communication with the first sensor and is configured to receive and process the output signal and classify a mode of the aircraft. A controller receives signal data from the logic management system and communicates with a control axis actuator to regulate a level of control authority provided to a pilot. The control authority is individually regulated within each integrator as a result of the individual landing gear states.
Abstract: A system includes an analysis system for performing an analysis and a motion capture environment interfaced with the analysis system. The motion capture system includes at least one sensor-tracker for tracking a location of a tracked object within the motion capture environment and one or more computers collectively operable to generate a virtual reality environment corresponding to the analysis.

Abstract: An acoustic signature reduction system for application typically on an aircraft. The acoustic signature reduction system uses a controller, power supply, and a thermo-acoustic tube such as a Rijke tube or Sondhauss tube to generate a cancellation noise of equal amplitude and inverted to that of noise generated by rotor blades when rotating. Acoustic signature reduction system can use a damping valve to make an intermittent cancellation sound to match the n/rev signature of the rotor blades with respect to a given reference location. The n/rev timing is different depending on the reference location therefore a cone of silence is created. A forced air unit may also be used to modify the phase of the cancellation noise in order to move the cone of silence around the aircraft.

The link having opposing end joints and a central joint that pivotally engages the drive disk. The system also having a gimbal device configured to drive a rotor hub and to allow gimbaling of the rotor hub with respect to a mast.

Abstract: A fabrication process using an integrated form includes assembling at least two independent sections of composite laminate about a form, such that at least a portion of the sections overlap. A bonding agent is applied between the sections, at the overlap, and the form and laminate assembly are vacuum-bagged. The bag is sealed around a vent in the form, and about the laminate assembly. A vacuum is applied within the bag, to bond the sections, and the bagged assembly is autoclaved, to cure the bonded laminate sections. The vent allows equalization of autoclave pressures within and outside of the form, to prevent crushing or deformation of the form during cure. The form becomes an integral and permanent part of the final composite product.
