DYNAMIC RESPONSE OF AIRCRAFT TO UNLOADED AND LOADED PAVEMENT PROFILES

The objective of this study was to determine whether or not there exists a significant difference in the simulated dynamic response of an F-4C aircraft traversing either an unloaded (undeflected) or loaded (deflected) pavement profile. The Air Force computer code, TAXI, was adapted for use on the Clarkson College IBM 360 Model 65 computer from the CDC 6600 computer used by the Air Force Civil Engineering Center. The TAXI code calculates the vertical accelerations at three points on an aircraft traverses a pavement profile. It appears that there is no significant difference in the response of TAXI to unloaded and loaded pavement profiles at speeds up to 133.3 feet per second. At higher speeds some rejections of the mean do occur, but in light of the continuous acceptance of the test of the distribution and the predominant acceptance of the test of the mean, these are felt to be insignificant. It appears that the present practice of using unloaded pavement profiles for aircraft dynamic response simulation is acceptable and loaded pavement profiles need not be obtained for this purpose.
