Components made of microcellular polyurethane elastomers, such as this jounce bumper or spring aid made of BASF's Cellasto, can reduce weight, absorb shock, and dampen sound and vibration in aircraft interiors. (Source: BASF)
Very comprehensive overview of the state of materials exploration in the aerospace industry. It was interesting to me that companies don't see composites as the be-all, end-all solution--a surprise given that so much attention and hype is focused on their deployment. I was also pleased to see that companies are keeping somewhat of a watchful eye on sustainability concerns as they vet out these new materials.
Beth, I also found it enlightening to discover the mix of materials being developed for, and used in, in bleeding-edge aircraft design. But composites are, in fact, a big part of all this, so it's not all hype. It was a big surprise, and encouraging, to see that sustainability concerns are finally reaching and influencing this industry, like so many others.
I saw no mention of cellular steel (superalloy) products. Inside and near turbine engines, the temperatures are too high for most of the materials mentioned. In fact the temperatures seem to be rising, to the point that many parts that were traditionally made of titanium alloys are failing. For quite a few years, we've been working both on traditional superalloy honeycomb and on other brazed cellular structures that can replace titanium and withstand much higher temperatures, and yet be weight-neutral or even weight-saving.
CPDick, thanks for that information. We focused on structural and interior component materials for this feature, not engines, but that's good input. It's especially interesting that temperatures are outpacing titanium. Can you give us your company name for possible followup?
You bet! It's Vertechs Enterprises (vertechsusa.com)
I just looked, and realized that the non-honeycomb sandwich products are not yet shown on our website. We have a number of such products that we have been developing and testing with major aerospace companies for quite a few years, and are just about to start producing our first full-scale product samples.
sometimes new ideas generate new discovweries, consider a study of all species of bird feathers and the incredible design weight, lift, etc etc, flexible wings to use both mechanical power and atmospheric changes , perhaps the ultra lights culd take on a new perspective> my wing collection has some very old feathers that have not changed over time as I keep studing these designs which are incredible' I think there is legislation forbading feather collections, but I have a deep native american background, the race card and holocaust is not in my deck. My spirit remembers the genocide of americas 20,000 tribes, and the role buffalo soldiers played when freed. I worked for a time at LTV Aerospace in the 60's on the A-7 series, while no bird is powered with fuel they can indeed do some pretty tricky stunts, like gliding for hours, with small wing shifts , in acord with atmospheric variables, fins do compensate to keep on course, but consideration of actual feathers may be in our future. whatever. Birds of prey do reach considerable speed, without any fuel at all,
Why would the biggest connector company in the world design and build the first fully functional 3D-printed motorcycle? To show TE Connectivity's engineers what the technology can really do in making working load-bearing production parts, and free up their thinking when approaching design problems.
In his keynote address at the RAPID 2015 conference last week, Made In Space CTO Jason Dunn gave an update on how far his company and co-development partner NASA have come in their quest to bring 3D printing to the space station -- and beyond.
A composite based on a high-performance PEEK-like resin we told you about two years ago when it was still in R&D has now been licensed by the US Naval Research Laboratory (NRL) for commercial manufacturing.
