Abstract: |
The Joint Strike Fighter Short Take-off and Vertical Landing (STOVL) aircraft will operate in desert environments and ingest abrasive particles during the critical take-off and landing stages of operation. Under such conditions, the compressor airfoils on the JSF STOVL aircraft's integrally bladed rotors (IBR) for both the lift-fan and cruise engines may get damaged which can lead to poor engine performance and potential failure. Since these IBRs are relatively large, it would be expensive to manufacture and replace. UES, Inc. proposes to develop erosion resistant coatings to maintain IBRs' performance (efficiency) and to delay its degradation due to sand erosion. The developed coatings will be evaluated in terms of erosion resistance and damping. Based on such evaluations the coatings will be ranked. Highly ranked coatings will be further developed in Phase II. |
Benefits: |
Successful completion of the project will provide highly erosion resistant coatings having high damping properties. Such coatings will enable to enhance the life of expensive IBRs of JSF STOVL. This technology will have many military and commercial applications including compressor airfoils on large turbofan engines powering commercial aircraft fleets. |
