Potential NASA Commercial Applications: The pneumatically actuated, trailing edge flap device for rotorcraft vibration control will be applicable to a wide range of end-users in the defense, commercial, and industry sectors. Its broad applicability is enabled by the scalability of the pneumatic artificial muscles for the entire range of small unmanned vehicles to larger transport vehicles. In addition to the noted NASA applications, vibration control in vertical take-off and landing systems is attractive to the military for tasks such as mine detection, troop insertion and extraction, and biochemical weapons cleanup; and commercial and industry tasks such as construction in hazardous terrain, maintenance of bridges and buildings, and storm tracking. The proposed flap technology will be an integrated hardware/software product that can be licensed for manufacture. Techno-Sciences, Inc. already enjoys market share of related technologies through our existing customers, and we plan to leverage these marketing outlets and offer pneumatic artificial muscle flap systems for advanced rotor upgrade packages. Potential Non-NASA Commercial Applications: Throughout the Phase I effort, Techno-Sciences, Inc. will work in concert with NASA sponsors to ensure that the proposed trailing edge flap device operated with pneumatic artificial muscles can be seamlessly integrated with existing rotor blade systems and future vertical flight technologies currently in development. These include single or multiple passenger vehicles for transportation, search and rescue operations, and package delivery, in addition to unmanned vehicles for meteorological and atmospheric measurements, operations in hazardous environments, and traffic control. To facilitate technology transfer, we will work in Phase I to address top-level hardware and software integration issues from a systems engineering perspective. Issues such as control electronics, software architectures, hardware interfaces, manufacturability, ruggedness, and reliability will be considered in Phase I and implemented in Phase II of the program.
