Study on influence of dense medium on impact pressure of detonation waves subjected to contact blasts

Xibei Gongye Daxue Xuebao
In order to investigate the buffering effect of the different dense medium on the shock waves in the contact blasts, a dimensional analysis method by using the zero-pressure sound speed of dense medium was proposed.

A framework of variable-length sequence data preprocessing based on semantic perception

Xibei Gongye Daxue Xuebao
Deep learning frameworks generally adopt padding or truncation operations toward variable-length sequences in order to use efficient yet intensive batch training. However, padding leads to intensive memory consumption, and truncation inevitably loses the

Multiperspective Structural Integrity Investigations on the Rotor Blade of Axial Flow Compressor Under Various Rotodynamic Loading Conditions Using Enhanced Computational Analyses

International Journal of Aerospace Engineering
Small gas turbine (SGT) engines power the latest generation of unmanned aerial vehicles (UAVs). This study investigates the axial flow–natured rotor blades of an SGT compressor. Rotor structures in axial flow compressors have failed due to complex stress
