Stress and Fatigue Analysis QRC-335A Pod. Revision C

Abstract

This report presents the results of a load and stress analysis made on the primary structure of the QRC-335A pod. lThe methods of stress analysis stem largely from previous tests and analyses made on virtually identical structures. The McDonnell Company furnished load data which was reduced to establish the flight loads for the QRC-160-8 pod on the F-4C pylon at BL = 81.50 inches, and the Sparrow III 6B installed semisubmerged in the forward fuselage of the F-4C aircraft. The analysis shows that adequate margins of safety were obtained for these loads. considering growth potential, some higher loads, called 'integration loads,' have been included to depict the worst case that would be encountered on the F-111A, F-4C, and F-105 aircraft. These loads have also been used to calculate the margins of safety which were found to be adequate. Because of conservation in the weight calculations, load analysis, and stress analysis, the margins of safety are likewise conservative.
