Maneuver Regime Recognition Development and Verification For H-60 Structural Monitoring

摘要

The Navy has been developing its flight usage survey and structural monitoring capabilities for helicopter applications for many years. This paper describes the development and verification process used to establish structural usage monitoring capability for the H-60 series helicopter models presently in the Navy inventory. The paper discusses the approach used to acquire and establish a database of known flight maneuver data for the aircraft. The process of developing maneuver recognition criteria using the flight test database is described along with a discussion of the verification process used to substantiate the maneuver recognition logic and software. The paper presents some examples of the methods used in processing the flight test data to develop and define selected maneuver recognition criteria and parameter thresholds. The paper also includes a discussion of some of the problems, limitations and issues related to maneuver recognition criteria development and verification. Selected maneuver examples are used to illustrate some of the difficulties in maneuver identification. The paper concludes with some recommendations with regard to the development and verification of maneuver recognition criteria for application to other models.
