F-111Positional Error Analysis when Mounted on 3Axis Positioner at RADC Newport Test Annex.

摘要

This report describes the procedures that were used to determine the true orientation of the F-111 aircraft mounted on the Scientific-Atlanta, Inc. three-axis positioner, model PAEA-85. The report describes the following aspects of this effort: (1) Establishment of the reference coordinate system for the aircraft and alignment of aircraft on pedestal, (2) Development of an inclinometer measurement system for determining aircraft orientation and for estimating errors associated with the aircraft positioning system, (3) Test program for evaluating probable errors in the positioner system, (4) Discussion of results of measurements and evaluation of probable system errors, and (5) Recommendations of procedures to be followed for aircraft alignment and for estimating probable system orientation errors.
