Bird striking engines are most likely to cause aircraft damage and accidents in bird strike accidents.In order to study the bird strike airworthiness performance of the first stage compressor rotor of the engine, bird strike tests are conducted on the engine rotor under working conditions.The bird strike test, in which the bird weight, velocity and
We have investigated the Auger higgs bookcase decay in the temporal domain by applying a terahertz streaking light field.Xenon and krypton atoms were studied by implementing the free-electron laser in Hamburg (FLASH) as well as a source of high-order harmonic radiation combined with terahertz pulses from an optical rectification source.The observed
In this research, the effects of foam content on mechanical property, thermal property and sound absorption of cellular lightweight geopolymer concrete (CLGC) were studied.The geopolymer mixtures were made with 15 M NaOH solution, sodium silicate/NaOH ratio sofia barclay sexy (NS/NaOH) of 1.00, sand/ash ratio of 1.25, liquid/fly ash ratio of 0.4.Th
