A STUDY OF REQUIREMENTS FOR ENGINE FAILURE PROTECTIVE WARNING SYSTEM IN SINGLE-ENGINE TURBINE HELICOPTERS

摘要

With the increased application of gas turbine engines to helicopters, problems have arisen in recovery following engine failure. The source of these problems appears to be the loss of the clear noise level change previously provided in piston engines as an indication of incipient power failure. The result is that the pilot may not be aware that a power failure has occurred until after the rotor speed has decayed below the allowable lower limit.
