Gulfstream has developed its new G-V aircraft as the next generation in the Gulfstream product line. This all-new aircraft will have a range of 6,500 miles, allowing it to fly from New York to Tokyo nonstop. The aircraft has an overall wingspan of 93.47 feet, almost sixteen feet greater than its predecessor, the G-IV-SP, and is more than eight feet longer. The airplane was essentially built by computer using a concurrent engineering approach. An important part of the concurrent engineering technology was the modal testing which was conducted prior to first flight. This testing was necessary to confirm analysis predictions of the dynamic behavior of the aircraft assembly. As much of the aircraft assembly was being conducted “just-in-time,” the rapid acquisition and confirmation of test data were essential.
