The F-15B (McDonnell Douglas, St. Louis, Missouri) airplane, tail number 836 was selected to fly Gulfstream Aerospace Corporation s (GAC) (Savannah, Georgia) QuietSpike (QS) project; however, this experiment is very unique and unlike any of the previous testbed experiments. It involves the addition of a relatively long quiet spike boom attached to the radar bulkhead of the airplane. This QS experiment is a stepping stone to airframe structural morphing technologies designed to mitigate the sonic boom strength of business jets over land. Prior to flying the QuietSpike boom on the F-15B airplane, several ground vibration tests (GVT) were required in order to understand the QS modal characteristics and coupling effects with the airplane. Because of the project s intense schedule, a 'traditional' GVT of the mated F-15B QuietSpike ready-for- flight configuration would not have left sufficient time available for the finite element model update and flutter analyses before flight test.
