Engineering Evaluation JOH-58A Helicopter with an Automatic Relight System.
Abstract
The United States Army Aviation Engineering Flight Activity conducted a limited in-flight evaluation of an automatic engine relight system installed in an OH-58A helicopter at Edwards Air Force Base, California, from 12 February through 11 April 1975. During the program, 33 test flights were flown for a total of 13.5 productive flight hours. Results of the evaluation showed that established limitations may be exceeded if the automatic relight system functions at certain points within the current operating envelope. Required additional limitations to the current operating envelope with the automatic relight system activated include in-ground-effect, hover below 10 feet and specific combinations of airspeeds and engine power settings. Two deficiencies and one shortcoming were noted during the evaluation.
