Abstract: This article presents a Jacobi–Ritz approach for conducting flutter and divergence analysis of a complex distributed propulsion aircraft wing similar to that of NASA X-57. The general orthogonal Jacobi polynomials are used ...

Abstract: Head injury model validation has evolved from against pressure to relative brain–skull displacement, and more recently, against marker-based strain. However, there are concerns on strain data quality. In this study, we ...

Abstract: To estimate the thermal properties from transient data, a model is needed to produce numerical values with sufficient precision. Iterative regression or other estimation procedures must be applied to evaluate the model ...

Abstract: The decomposition of solid electrolytes at the surface of the cathode has become one of the critical bottlenecks in the further widespread of all-solid-state batteries. To this end, we applied a fluidized bed coating method ...

Abstract: A multistage vaneless counterrotating turbine (MVCRT) eliminates vanes between rotors, which reduces the weight and size of the turbine and avoids viscous losses associated with vanes pronouncedly. An aircraft engine ...

Abstract: Profiles of current velocity, temperature, and salinity were obtained in the Internal Wave and Mixing Experiment in the South China Sea (SCS), the Luzon Strait, and the North Pacific. The observations are examined for ...

Abstract: The oxidation behavior of Ti6Al4V titanium alloy under laser irradiation in atmospheric and oxygen-assisted conditions was studied. A nanosecond-pulsed Yb: glass fiber laser was used. The thickness of oxide layer, ...

Abstract: The aero-engine casing is a key component for carrying loads. With the purpose of improving the thrust-weight ratio of the aero-engine, the casing is required to be designed to be as thin as possible. Therefore, the vibration ...

Abstract: This paper proposes an integral hydrobulge forming (IHBF) method using a triangular patch polyhedron as the closed preform shell. When triangular flat parts are welded along the edges in sequence, triangular patch polyhedra ...
