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.
Challenge:Building a variable buoyancy air vehicle
Solution:MSC Nastran and Patran were used to build an FE model which generated detailed structural performance information for the preliminary design including displacements, strains and stresses. This information not only characterized the performance of the preliminary design but also provided insights into how the performance could be improved.
