Aircraft turboshaft engines frequently require fast response power turbine overspeed protection.
Reliability considerations dictate a direct and independent sensing of turbine speed. Severe component environmental conditions coupled with the need for high reliability and long life make design of electrical engine mounted components a design challenge.
This paper cites component requirements, design problems, and solutions associated with the successful development of an electrical overspeed system for the General Electric aircraft T64 gas turbine engines.
