Abstract:

This letter report presents the estimated range performance of the UH-1C helicopter equipped with a Lycoming T53-L-13 engine. The range performance was analytically found to be substantially increased. This calculated increase in cruise airspeed and range factor will greatly enhance the mission capability of this helicopter. However, this increase would be dependent on satisfactory handling qualities and vibration characteristics at the increased cruise airspeed. Therefore, engineering flight testing of the UH-1C helicopter is considered to be mandatory when the T53-L-13 engine is installed.
