Aeros Develops Revolutionary Vehicle Buoyancy Air Vehicle with MSC Nastran.
The Aeroscraft is a unique variable buoyancy air vehicle developed by Worldwide Aeros Corp. that combines elements of lighter-than-air crafts such as airships with conventional heavier-than-air aircrafts. The unique design of the Aeroscraft requires high weight efficiency (low ratio of weight over hull surface area) and provides advantages compared to conventional airships but also creates significant challenges in the design and optimization of the structure.
Aeroscraft engineers overcame these challenges by using MSC Nastran to build a finite element (FE) model that was used toptimize the structure. One of many MSC capabilities that simplified the analysis was its automatic inertia relief method that automatically creates inertia forces and moments to counterbalance external loads.
“MSC Nastran provided a very convenient platform to perform complex analyses of the Aeroscraft structure,” said Lin Liao, Aeronautical Engineer for Worldwide Aeros Corp.. “Using this tool, we were able to significantly reduce the weight, optimize configuration, and complete the design in less time than would have been required using traditional design methods.”
