A recent study conducted for the aerospace industr y showed that more than 29 percent of microwave assemblies fail during installation, and aircraft manufacturers have accepted the practice of simply replacing them. However, with the need to decrease costs, they can no longer afford the total cost associated with assemblies that cannot withstand the installation process and the extreme conditions of aerospace. Manufacturers need assemblies that provide the same level of electrical performance before and after installation as well as throughout their ser vice life. Performance Testing with an Installation Simulator W. L. Gore & Associates (Gore) has designed a simulator to evaluate the stress of installation on microwave airframe assemblies. The simulator has several features that replicate minimum bend radius conditions, routing guides that induce torque, and an abrasion bar to simulate routing across sharp edges or through access holes in the airframe structure. The simulator enables Gore not only to evaluate the electrical performance of various cable assemblies after installation but also to design products that meet real application challenges. Testing electrical characteristics such as insertion loss and VSWR before and after routing through the simulator verifes whether an assembly can withstand the rigorous challenges of installation – resulting in lower total costs and longer ser vice life. GORE-FLIGHT™ Microwave Assemblies, Series 6 VSWR Performance That Meets the Challenge Gore has engineered new ruggedized, lightweight and vapor-sealed airframe assemblies that withstand the challenges of aerospace. These assemblies – known as GORE-FLIGHT ™ Microwave Assemblies, 6 Series – improve system performance with: • Outstanding signal integrity with lowest insertion loss before and after installation • Lower installation costs due to fewer failures and reduced aircraft production delays • Improved fuel effciency and increased payload with lightweight assembly • Longer system life and reduced downtime due to mechanically robust construction • Less RF interference among electronic systems due to superior shielding effectiveness • Proven compliance with MIL-T-81490 requirements When compared to other leading airframe assemblies, the 6 Series maintain lower insertion loss, more reliable VSWR performance, and consistent impedance of 50 ± 1 Ohms, eliminating insertion loss stack-up issues when routing through airframe bulkheads. With GORE-FLIGHT ™ Microwave Assemblies, 6 Series, a ft-and-forget philosophy is now a reality – providing the most cost-effective solution that ensures mission-critical system performance for militar y and civil aircraft operators.
