In response to evolving operational and environmental conditions, weight reduction has become a critical element in aircraft design and has created an increasing customer demand for weight-conscious sealing components. As a result, Simrit, a global supplier of precision-manufactured products for the aerospace industry, recently developed a proprietary, low-density silicone material that was successfully used in nacelle systems developed by a leading full-service independent nacelle system supplier.
Nacelle systems, housings that contain aircraft engines, are critical to the overall efficiency of aircraft, as well as a key area for weight savings and fuel economy improvements. Simrit developed its cost-effective AMS 3302 and AMS 3303 silicone material to provide a 15% to 20% weight savings over similar materials. With a specific gravity of less than one, it has the same physical properties of traditional silicone materials, but at a reduced weight.
“As our customers encounter changing operating conditions, Simrit strives to be a partner that they depend upon to offer forward-looking solutions that can be customized to fit precise application needs,” says Todd Blair, business / product development manager, Freudenberg-NOK Sealing Technologies. “Our innovative low-density silicone material is just one example of how Simrit is working to anticipate industry changes, so we can provide customers with solutions when they need them.”
Simrit’s low-density silicone material is an ideal solution for numerous aerospace sealing applications, including airframe seals and pressure and environmental sealing applications of nacelle systems. Developed to meet widely accepted international specifications, the material withstands extreme low and high temperatures, is resistant to common aircraft fluids and can be combined into fireproof constructions.
“In the ever competitive commercial aerospace market, airlines are being required to do more for less,” said Vinay Nilkanth, vice president global sales aerospace, Simrit. “Our low-density silicone material provides the critical weight saving benefits customers seek, without compromising other physical properties.”
