Interior noise concerns are present in civil aircraft design since the structural-acoustic performance is directly related with the perceived product quality and the occupant comfort. Currently, structural-acoustic concerns are typically addressed late in the design cycle when the structural configuration has been finalized. Therefore bringing structural acoustic simulations early in the design cycle will offer cost and weight savings. Thus, there is a great market potential for the outcome of this SBIR in the aircraft manufacturing industry. The proposed development fits well the business activities of the proposing firm in the area of computational structural-acoustics and in product design.
Structural-acoustic concerns are present in aircraft structures, launch vehicles, and spacecraft, since they are directly related with occupant comfort and noise induced vibration on payloads and electronic equipment. In all of these areas decisions made early in the design are critical for the performance and the cost of the system. Currently, structural-acoustic concerns are typically addressed late in the design cycle when the structural configuration has been finalized. Bringing structural acoustic simulations early in the design cycle will offer cost and weight savings. Therefore, the proposed developments will be useful to all NASA groups interested in reducing weight and cost when designing aircraft, launch vehicles, and spacecraft.
