Failure of critical engine components such as compressor, fan, and turbine disks during flight can cause the loss engine, aircraft, or even life. To reduce risk this failure flight, different methodologies tools have been developed to determine safe operating life these disk components. The two most widely used lifing methods, safe-life damage tolerance, are inherently conservative, retiring al...

Our research group has been developing an aero signage display. The word ‘aero’ means that its image is floating in the air. authors have noticed important technology ‘transparent.’ Suppose you find out window decals which are put on glass of shops. You end up watching mirrored images if watch transparent from inside shop. In signage, technique enables to display unidirectional (or one‐way) obs...

Data-driven Remaining Useful Life (RUL) prediction is one of the core technologies Prognostics and Health Management (PHM). Committed to improving accuracy RUL for aero-engines, this paper proposes a model that entirely based on attention mechanism. The divided into multi-head self-attention timing feature enhancement models. employs scaled dot-product extract dependencies between time series; ...

The optical environment around both a hemisphere-on-cylinder turret and a hemisphereonly turret with flat and conformal windows was characterized at both subsonic and transonic speeds. Data was taken from Mach 0.4 to 0.65 at altitudes from 15,000 ft to 30,000 ft to analyze scaling laws, with a focus on Mach numbers of 0.5 and 0.65. A 25 kHz ShackHartmann wavefront sensor was used to measure the...
