Comfort and illumination apparatus for a passenger space

Abstract: A comfort and illumination unit especially for a passenger space in an aircraft is constructed for cooperation with a straight wall panel that can be integrated in or secured to a vertical straight wall and/or a horizontal straight ceiling wall. The unit has a mounting base and a cover with passenger convenience elements mounted to the base under the cover which is provided with cut-outs for access to the convenience elements. Fluorescent bulbs form a frame around the convenience elements.

Reduction of Landing Gear Noise using Meshes

Abstract: Acoustic and resistance measurements were performed in NLR's Small Anechoic Wind Tunnel on a large number of meshes intended for landing gear noise reduction. The meshes were tested on generic bluff bodies which simulated single and combined landing gear struts. An out-of-flow microphone array was used to localize and quantify the noise sources on the model. It is found that the meshes yield a drastic broadband noise reduction for a wide range of mesh materials and mesh shapes. The noise reduction occurs for all tested angles of attack and for all tested models. For the combined bodies it is found to be sufficient to treat only the upstream component with a mesh.

Height tailoring of interfacing projections

Abstract: A method of joining a first component to a second component, the method comprising forming an array of projections extending from a bond surface of the first component, the projections having a plurality of different profiles; and embedding the array of projections in the second component formed of a plurality of laminate plies, wherein each projection profile is adapted to best transfer load into a respective one of the laminate plies. The resultant joint is able to transfer load more progressively between the two components leading to improved tensile strength.

Thermo-mechanical performance of an ablative/ceramic composite hybrid thermal protection structure for re-entry applications

Abstract: Hybrid thermal protection systems for aerospace applications based on ablative material (ASTERM™) and ceramic matrix composite (SICARBON™) have been investigated. The ablative material and the ceramic matrix composite were joined using graphite and zirconia–zirconium silicate based commercial high temperature adhesives. The thermo-mechanical performance of the structures was assessed from room temperature up to 900 °C. In all the joints there is a decrease of shear strength with the increase of temperature. Analysis of the fractured surfaces showed that above 150 °C the predominant mode of fracture is cohesive failure in the bonding layer. The joints fabricated with the zirconia–zirconium silicate based adhesive present the best performance and they have the potential to be used as hybrid thermal protection systems for aerospace applications in the temperature range 700–900 °C.
