KAflex Drive Shaft Coupling for UH-1 Helicopter. Design Refinement.

Abstract

A KAflex coupling shaft, using flexing metal elements to accommodate misalignment has been designed as a replacement for the main drive shaft coupling of the UH-1 helicopter. Previous program phases explored the feasibility of this approach through analysis and test of a prototype coupling shaft. The program phases covered in this report include an examination of compatibility of the coupling shaft to the space envelope and operating conditions encountered in the UH-1 installation, and refinement of the prototype design to reflect the results of this and previous examinations. A mock up installation of the prototype coupling shaft is made, clearances are evaluated and lateral natural frequencies are measured and verified through analysis.
