ENGINEERING REPORTS ON AHIMA (WAVE HEIGHT SENSOR) TESTS.
Abstract
The objectives of this test program were to ascertain whether the AHIMA system could function operationally in a deep ocean environment, whether it could be correlated to existing references in such an environment, and whether its housing would be affected by the magnitude of wave heights. Since most of the operational testing had been conducted in the Chesapeake Bay and in tow tanks, deep ocean tests were scheduled. However, in order to rely on the data received from increasing wave heights, theoretical calculation had to be verified as to whether drag on the sensor's housing affected the sensor's accuracy. Thus a series of drag tests were conducted, which indicated that there was not sufficient influence on the housing to noticeably affect the sensor. The deep ocean tests were conducted in wave conditions up to 15 feet. The response of the system and its handling characteristics were well within specifications. And, correlation with existing references was excellent. The next phase is to provide automatic data reduction to the excellent magnetic recordings obtained from the several tests and to provide a display which compares wind conditions with significant and average wave height.
