  • Variable camber fluid-dynamic body utilizing optimized smart materials
    Patent number: 9120554
    Abstract: A system and methods for configuring a fluid-dynamic body is disclosed. A camber of a fluid-dynamic body is configured by activating a shape memory alloy actuator coupled to the fluid-dynamic body.
    Type: Grant

  • Curved fiber paths for composite laminates
    Patent number: 8756037
    Abstract: A computational optimization process uses the variable stiffness performance of composite laminates attributed to steered fiber to guide the design of stream functions describing the fibers to build it. This design process combines a finite element-based analysis tool, failure criteria and geometry optimization to determine steered angles associated with stream functions by an optimization program to meet target performance requirements, e.g., load condition(s), and failure criteria for quasi-static or dynamic events. The fiber angle distribution and thickness buildup are computed based on the stream function. The simulated structure is analyzed using finite element analysis. The disclosed process allows the designer to impose manufacturing constraints such as fiber steering radius.
