Book excerpt: This report describes the results of a 20-month program, beginning in June 1974, designed to investigate parameters which effect the foreign object damage resulting from ingestion of birds into fan blades of a QOSEE-type engine. Work performed on this program included the design, fabrication, and impact testing of QOSEE fan blades to demonstrate improvement in FOD resistance relative to existing blades and also the design and demonstration of a pin root attachment concept. In the first phase of the program, it was found that, in general, for the small objects used, the strains in the blade are proportional to the mass of the impacting object and the square of the relative velocity component normal to the blade chord at the impact location. These parameters can be further combined into an average or nominal force normal to the blade at the impact location. A finite element computer program gave results that compare well with the test data. In the second phase of the program four improved blades exhibited substantial improvement in FOD resistance relative to former designs.

Available in PDF, EPUB and Kindle. Book excerpt: The successful application of advanced composites as the structural material for aircraft jet engine rotating parts will significantly reduce engine weight and improve engine performance characteristics. To solve the component design, manufacturing, and quality assurance problems associated with such an application, a program was conducted to design and develop BORSIC/Aluminum third-stage fan blades, which would operate satisfactorily in the TF30-P-7 or P-9 engine models. Program objectives were to improve the existing design of a composite material fan blade, manufacture the blade, and demonstrate its quality by bench and engine environment testing. The scope of the program required to successfully meet these objectives included establishing design and fabrication procedures, developing special tooling, evaluating current nondestructive inspection techniques and adapting these techniques to composite materials, establishing quality assurance criteria, and developing comprehensive bench and engine environment test programs to adequately demonstrate fan-blade quality. During the program, several sets of BORSIC/Aluminum blades weighing 40 percent less than comparable TF30 bill of material titanium blades were successfully produced and tested. Based on this extensive test program, and with the establishment of quality control criteria and repair procedures, the blades were deemed acceptable for evaluation in a flight program. During the total program, 246 engine-configuration blades were manufactured and non-destructively inspected; with an overall acceptance rate of 92.3%.
