Abstract Engineered products have economic, environmental, and social impacts, which comprise the major dimensions of sustainability. This paper seeks to explore interactions between design parameters when impacts are incorporated into concept development phase systems process. Social impact evaluation is increasing in importance similar what has happened recent years with environmental conside...

Large-flow, high-pressure fans are required to improve the shape-keeping and flight-height-adjusting ability of stratospheric airships. This study optimizes analyzes a fan MIX-130 suitable for airship. Five design parameters selected optimize fan’s static pressure rise efficiency: impeller outlet installation angle, angle increment, blade thickness, diffuser tilt L16(45) orthogonal test optimiz...

In recent years, high-altitude aerostats have been increasingly developed in the direction of multi-functionality and large size. Due to size high flexibility, new challenges for appeared configuration test deformation analysis. The methods analysis airship researched discussed. A tested method configuration, named internal scanning, is established quickly obtain spatial information all surface...
