Field Repair of Localized Damage on Dynamic Rotorcraft Components.

Applied Ultrasonics, Inc. has developed a unique patented commercialized, device that has proven successful in treatment of metals in the automotive and transportation industry. The goal of this SBIR effort is to demonstrate the feasibility of using this technology to improve the repair process of aviation components. The process known as Ultrasonic Impact Technology (UIT) can be compared to shot peening; however with three distinct advantages: 1) It uses a man portable device that can be used in forward deployed locations—eliminating the need to send parts to a specialized repair facility. 2) UIT can be used on aviation components that cannot be repaired with shot peening due to their size or shape. 3) The results of treatment with UIT are significantly greater than shot peening--greater fatigue life enhancement, corrosion prevention, and surface hardness. The goal of this Phase I effort is to demonstrate the feasibility of incorporating UIT in the Army's Aviation repair processes. Phase II will provide demonstration and airworthiness qualification on specific components. Commercialization of this technology will significantly reduce aviation operation and maintenance costs.
