In This paper, a parametric study of compressor performances was performed by streamline curvature method (SLC). Effects of three input parameters in design process, e.g., number of blades, distribution of blade thickness, and blade sweep angels, on the main objective parameters in aerodynamic design, e.g., velocity distribution, efficiency and pressure ratio, has been investigated in the param...

The Advance Mirror Technology Development (AMTD) project is in Phase 2 of a multiyear effort, initiated in FY12, to mature by at least a half TRL step critical technologies required to enable 4 meter or larger UVOIR space telescope primary mirror assemblies for both general astrophysics and ultra-high contrast observations of exoplanets. AMTD Phase 1 completed all of its goals and accomplished ...

The paper presents an algorithm for case-based synthesis of single-input single-output power-drive systems based on dynamic behavior design speciications. The case-base consists of electro-mechanical components modelled using the bond-graph formalism. An hierarchical classiication scheme for devices that distinguishes between the functional and structural aspects of a device is described. The s...

Parametric Urbanism, pioneered by Zaha Hadid & Patrik Schumacher Architects with support coming from advanced computational technology, has been the interest of architects and urban designers in recent years. This new design thinking has been used in projects ranging from large scale urban development to building façade/surface design. However, the integration of demographics, cultural, and hum...

To enable the designers to design and modify model of nuclear channel head quickly and easily, we constructed the CAD system of the nuclear channel head. At first, we analyzed the geometric characteristics of nuclear channel, established of feature control parameter set and the parametric model of nuclear channel head. Secondly, other parameters related to the solid modeling are described throu...
