Abstract: The objective of the analysis is to demonstrate how the Boltzmann-Arrhenius-Zhurkov (BAZ) model, originally suggested by Zhurkov in the kinetic concept of the strength of solids as a generalization of the Arrhenius theory of chemical reactions, can be effectively employed for the prediction of the lifetime of electronic materials experiencing ionizing radiation. The "loading term" γσ in the original BAZ model, where σ is the tensile mechanical stress and γ is the sensitivity factor, is replaced with the term γRD, where D is the radiation level and γR is the sensitivity factor. Leakage current measured during the failure-oriented-accelerated-testing (FOAT) is considered in our analysis as a suitable indication/criterion of the level of the induced damage. FOAT terminates, when the agreed upon critical value of the leakage current is reached.

Abstract: Box wing aircraft weight issues, structural interactions as well as inter-wing joint designs differ remarkably from Conventional Cantilever Wing configuration and present design challenges which have been extensively investigated by several researchers. This study discusses the results of such investigations in order to highlight the prospects of the Box-Wing aircraft as well as pending structural design challenges that require further examination.

Abstract: Aerodynamic Forces mainly lift and Drag acting on an aircraft, are directly related to the geometry and wing profile of an aircraft. In this research we first designed a blended wing UAV (using X48B as a baseline model) and then performed the CFD analysis. Focusing on the lift to drag ratio in Cruise conditions, we made changes to our initial design based on critical pressure regions found by simulation and afterwards improved our design to almost three times by making changes to the initial geometry.
