摘要:
An avionics chassis for protecting against damage, dust, dirt and incidental moisture over an extended temperature range, EMI shielding to prevent radiation of internal circuit energy and preventing the entrance of external EMI. The chassis provides lower weight, lower levels of radiated emissions and improved resistance to incident external radiation. Electric and magnetic shielding is also provided.
摘要:
The inventive subject matter provides methods of manufacturing bulk absorbers and noise suppression panels. In one embodiment, and by way of example only, a method of manufacturing bulk absorbers includes mixing a first type of fibers and a binder together to form a material mixture, the first type of fibers comprising ceramic microfibers, and the binder comprising a glass material, hydrating the material mixture with water vapor to form a hydrated mixture, and heat treating the hydrated mixture to form the bulk absorber

Noise suppression materials and methods of manufacturing noise suppression materials are provided. In an embodiment, by way of example only, a fibrous material includes a network of a plurality of fibers selected from a group consisting of glass fibers and ceramic fibers, the plurality of fibers including a first fiber and a second fiber, the first fiber having a first low melt component and a first high melt component, the first low melt component of the first fiber having a first melting point, the first high melt component of the first fiber having a second melting point that is higher than the first melting point, wherein the first low melt component of the first fiber extends alongside and is adjacent to at least a segment of the first high melt component of the first fiber and is bonded to the second fiber at a contact point.
摘要:
Platinum containing coatings for corrosion and oxidation protection of a substrate, and platinum electrodeposition methods for coating a substrate. The coating may comprise platinum and at least one supplementary constituent, and the method may involve co-electrodeposition of platinum and the supplementary constituent from a single electrolyte composition. The supplementary constituent may comprise chromium, an oxidation protective reactive element, or an alloy of chromium with a reactive element. Components protected by such coatings are also disclosed.
摘要:
A method for coating compressor or turbine blade tips of a bladed disk with abrasive particles includes installing the blades onto a disk, and then cold gas-dynamic spraying the abrasive particles onto the blade tips while the blades are installed in the disk. According to another embodiment, a method for coating compressor and turbine blade tips of a bladed wheel with abrasive particles includes grinding the blade tips to bring the bladed wheel to a predetermined diameter. Then, surfaces of the bladed wheel not requiring coating are masked. After masking the surface not to be coated, the abrasive particles are cold gas-dynamic sprayed onto the blade tips. For both embodiments, an oxidation resistant layer may be cold gas-dynamic sprayed on the blade tips prior to spraying the abrasive particles.
