This can significantly reduce stockpile availability, consequently increasing procurement costs. If historical data is the only measurement of missile readiness available to a stockpile manager, then all missiles must be retired by their expected failure date. Damage Tolerant Structural Design Practice requires sizing the product cross section to tolerate the worst-case flaw that might be missed during NDT. NonDestructiveTesting screens out manufacturing flaws that would otherwise degrade the product performance below the fundamental material properties. The technicians there can perform the test and return the aircraft to service. While this average rate provides a broad sense of stockpile reliability, it does nothing to detect missiles that have failed before their time, and those which have outlasted their expiration date.įor aviation NDT, your best resource is a qualified FAR Part 145 Repair Station with NDT capability. Instead, militaries rely on a constant rate of failure based on historical missile performance. Using visual inspection techniques, it is impossible to determine with a high degree of reliability which missiles will work and which will not. In storage, missile components and housing corrode and degrade over time to the point where they will not accurately travel to their target, will not arm, or will not fire. By examining specific examples of how NDT techniques improve missile testing, we can see how nondestructive testing can benefit the military as a whole. As missiles have grown increasingly central in modern military planning, so has the use of NDT technology to ensure missile reliability and longevity. Militaries around the globe have employed nondestructive technologies to test a wide variety of hardware for over half a century, from small arms ammunition to reactor containment on submarines, and have learned to trust the usefulness of NDT techniques. Only by testing systematically can militaries prevent the deployment of duds and unsafe or unusable equipment. Military Nondestructive Testing Examples: Improving Missile Stockpile Reliabilityīy employing nondestructive testing (NDT) technologies in a rational, systemic manner, militaries are able to improve the reliability of their munitions, vehicles, and infrastructure.
