Content Inside: The design methodology uses a combination of high and low fidelity tools to assess the performance and acoustics of the aircraft. The goal set by the Silent** Aircraft Initiative is a viable, commercial aircraft design with noise levels imperceptible outside the airport perimeter in a well-populated urban environment. To ...

Content Inside : Analytical Target Cascading (ATC) is a product development tool that computes component design specifications such that the final system design is consistent and meets design targets. ATC is useful for complex product design that must be approached by decomposition, and facilitates concurrent design activities. While ATC has been ...

Content Inside : This paper presents a three-dimensional airframe design methodology for low noise emission and high fuel efficiency, based on a blended-wing-body type aircraft. The design methodology uses a combination of high and low fidelity tools to assess the performance and acoustics of the aircraft. Three-dimensional view of the current ...

Content Inside : Overview of Design Approach, Signs and Conventions, Aerodynamic Design Criteria, Aerodynamic Design Methodology, Structural Design Considerations, NREL Airfoil Families, Eppler Calculations of Airfoil Properties, Performing Rotor Design Studies with PROPID, Design Process for Near-Optimal Variable-Speed Performance, Example Rotor Design, As a part of its Advanced Research Program, the ...

Content Inside : Using this methodology, engineers can define the frame of a new car body, respecting the company standards. The principal benefit is the reduction of the design development time as the modification process is optimized. Furthermore the design history is recorded and the same parametric models can be re-used ...

Content Inside : Composite materials provide design flexibility in that fiber placement and orientation can be specified and a variety of material forms and manufacturing processes are available. It is possible, therefore, to “tailor” the structure to a high degree in order to meet specific design requirements in an optimum manner. ...

Content Inside : ABSTRACT Traditional commercial aircraft design attempts to achieve improved performance and reduced operating costs by minimizing maximum takeoff weight. From the point of view of an aircraft manufacturer, however, this method does not guarantee the financial viability of an aircraft program. To assess the long-term financial impact of ...

Part of Content : The Analysis optimization using WAVE Cycle Analysis and an iSight Optimization Framework, The methodology was applied to analyze the power output of a Harley-Davidson Spark-ignition V-Twin engine as a function of fifteen complex design parameters (15 controllable factors.) The framework of the optimization entailed using a ...

Part of Content : In recent years, we have been developing a set of heuristics or design principles, that on the one hand capture theoretical insights about intelligent – adaptive – behavior, and on the other provide guidance in actually designing and building systems. In the past the focus in the ...
