Abstract: Disclosed is a means for reducing jet engine exhaust noise wherein mixing is enhanced between adjacent exhaust flows and between exhaust flow and free-stream flow. Also disclosed is a means for improving the thrust of jet engines and for reducing the noise and drag of aircraft. The device is a segmented, triangular or trapezoidal shaped, curved extension to a nozzle's sleeve or surface trailing edge that results in a serrated trailing edge. The extensions enhance the natural free mixing of the adjacent flows and therefore reduce the acoustic energy associated with the velocity differences between the streams in which they are imbedded. The novel structure forces adjacent flows to penetrate into one another to a greater depth than that achieved with free mixing and results in a more uniform flow in a shorter stream wise distance. As a result of the enhanced mixing, drag on flow surfaces that are downstream of the devices and are scrubbed by the flows adjacent to the devices can be reduced.

Abstract: A grounding contact member for electrically connecting cooperating metal shells in a coupling comprises a metal band divided along both edges into several spring contact fingers that are bent inwardly into two U-shape portions. The contact member is located in an annular recess around the inside of a coupling ring with the fingers at one end engaging the metal shell on which the coupling ring is mounted and the fingers at the other end engaging the other metal shell to which the coupling ring is connected.

Abstract: Disclosed is a segmented mixing device for reducing jet engine exhaust noise wherein mixing is enhanced between adjacent exhaust flows and between exhaust flow and free-stream flow. The device does so with a very small degradation in aircraft performance. The device is a segmented, triangular or trapezoidal shaped, curved extension to a nozzle's sleeve that results in a serrated trailing edge. The nozzle extensions enhance the natural free mixing of the jet's exhaust flows and therefore reduce the acoustic energy associated with the velocity differences between the streams in which they are imbedded. The novel structure forces adjacent flows to penetrate into one another to a greater depth than that achievable with free mixing and results in a more uniform flow in a shorter stream wise distance while limiting high frequency noise through utilization of root radii in the order of 15 to 20% of the segment's width at the intersection of a parent nozzle.

Abstract: An aft in flight entertainment system “IFE” which allows air to be directed to and exhausted from the IFE equipment in isolation from the cabin conditioned air. Further potential IFE generated smoke may be kept isolated from the cabin air. The aft IFE equipment is located in the rear sections of the aircraft. Valves controlling air flow are responsive to input signals. A fan draws cooling air through a video control cabinet through a duct which splits into an overhead branch and an inboard branch.

Abstract: A method for producing stable atmospheric pressure glow discharge plasmas using RF excitation and the use of said plasmas for modifying the surface layer of materials. The plasma generated by this process and its surface modification capability depend on the type of gases used and their chemical reactivity. These plasmas can be used for a variety of applications, including etching of organic material from the surface layer of inorganic substrates, as an environmentally benign alternative to industrial cleaning operations which currently employ solvents and degreasers, as a method of stripping paint from surfaces, for the surface modification of composites prior to adhesive bonding operations, for use as a localized etcher of electronic boards and assemblies and in microelectronic fabrication, and for the sterilization of tools used in medical applications.

Abstract: A corrosion resistant gasket for aircraft, and more particularly to encapsulation of a conductive mesh in a pliable fluorosilicone compound that will not become bonded to mating surfaces and will also migrate upon compression during installation to the threads of attaching hardware utilized between the instrument, antenna, and aircraft structure, thereby reducing corrosion through the attaching hardware, by providing a hermetic seal around the periphery of the envelope of the attached device. In addition, a flexible seal comprising a fluorosilicone, a silicone, and silica is disclosed. The flexible seal provides a fluid-resistant barrier and is readily installed and removed from electrical and/or mechanical components in conjunction with the use of a conductive corrosion resistant gasket described in U.S. Pat. No. 5,791,654.

Abstract: This invention relates to a hard landing indication system that will provide a quantitative assessment that a hard landing did or did not occur at the last landing of an airplane. A hard landing can cause structural damage to an airplane. An airplane that has been declared to have a hard landing must be grounded until an inspection of the structure has been made to determine if repairs are required.

Abstract: An access platform comprising a series of stackable polyurethane foam block assemblies that when properly secured to each other creates a set of steps and handholds similar to a ladder. At the top of the platform a maintenance person can stand on a nonskid surface and perform the work needed at any required height. The ladder is radially curved to fit between the thrust reverser sleeve (deployed) and the inner fan duct wall. This radial diameter between the GE, Rolls Royce and Pratt Whitney engines varies within inches. The main access blocks of the access platform can be used on all three engines by using different foam wedges and wall blocks to secure the assembly tightly in place. Over 70% of the blocks are useable on all three engine types, thus reducing the number of overall parts required.
