Abstract: This paper presents the experimentation and finite-element analysis of a unique structure called a celestial icosahedron. The structure is being considered in a project related to lighter-than-air vehicles. The dimensions ...

Abstract: This paper attempts to characterize the various methods that may be used in defining the vibration features of a plate dimensionally proportioned to represent a turbine compressor blade. The comparison is specifically ...

Abstract: This paper presents an analytical procedure for predicting instability loads of composite tires using a simplified tire model. The tire is modeled as a closed composite torus with geometric nonlinearities. The equations ...

Abstract: The research reported herein makes use of finite-volume simulations of morphing continuum theory (MCT) to reproduce critical relations of thin-airfoil theory for the simple configuration of a flat plate for supersonic and ...

Abstract: The concept of vacuum lighter-than-air vehicles is a generalization of the idea behind floating vehicles, which enclose a volume of gas that is lighter than air. In particular, the enclosed volume is completely evacuated. ...
