Rotor Track and Balance (RTB) is a necessary maintenance action to improve aircraft ride quality and decrease fatigue for both the aircrew and helicopter equipment. While there have been a number of papers discussing the solution strategy for optimizing both blade track split and vibration, little work has been reported on how to calculate blade track by using an optical sensor. This paper will discuss the formulation of the blade track height estimate based on optical tracker measurements from flight-testing. Furthermore, the article will include a sensitivity analysis to define the blade track height error. Finally, contending solutions strategies are tested by comparing the results between two pulse and three pulse optical trackers.
