Model Test of Pratt & Whitney Aircraft XR-4360-4 Engine

Abstract

In accordance with specifications AN-9502B and AN-9504, a Pratt & Whitney XR-4360-4 reciprocating aircraft engine was tested to determine its endurance, dive, and crankshaft torsional vibration characteristics. The Pratt & Whitney XR-4360-4 engine is an air-cooled, four-row, radial, 28-cylinder power plant with variable-speed supercharger. The engine was scheduled for a 150-hr type test endurance run, but due to the various failures which occurred, the endurance tests were terminated at the half-way mark. On acount of the test results, it was decided that, in its present stage of development, the XR-4360-r engine is not suitable for service use. It is recommended that the engine be redesigned and development work be expedited to correct and improve the endurance qualities of all defective parts.
