Fan-in-Fin Failure Rate and Scrap Analysis.
Abstract
This report presents an analysis of field-collected reliability, maintainability, and cost data reported for selected fleets of Alouette II, Alouette III, and SA 341 helicopter antiorque systems that accumulated 10,000 to 15,000 flight hours per aircraft model. The purpose of this program was to study the reliability, maintainability, safety and cost characteristics of an antitorque systems of the fan-in-fin type compared with an equivalent antitorque system of the conventional tail rotor type, in order to furnish bench mark data for the design of furture helicopter antitorque systems. The Aerospatiale built SA 341 Gazelle was monitored in commercial operations for the fan-in-fin data. Both the Alouette II and Alouette III (also made by Aerospatiale) were monitored in commercial operations to obtain the conventional tail rotor data.
