Generating Methods of Severe Load Spectra for Airplanes Based on Statistic Analysis in Flight Subjects

Hangkong gongcheng jinzhan, 2019
Nowadays, the mean load spectra is mostly used in fatigue test for aircraft, but it has the defects of long fatigue cycle. The severe load spectra is used instead, which can shorten the test time greatly. In order to meet the demand of full-scale fatigue

Remote Monitoring of Fatigue Cracks Growth in the Aircraft Structure Based on Active Piezosensor Network during the Full Scale Fatigue Test [PDF]

Key Engineering Materials, 2013
One of the major issues from a structural integrity point of view of the aircraft structure is an appropriate health monitoring technology delivery for the damage tolerant philosophy. This paper presents a development of a system for fatigue crack growth monitoring and early damage detection in the PZL 130 ORLIK TC II turbo-prop military trainer aft ...

Electrostatic Self‐Assembly Induced Nest‐Like MXene Networks on Fabric for Ultra‐Broadband Flexible Absorption

Advanced Science, EarlyView.
In this study, an electrostatically self‐assembled WPU‐MXene@FC flexible fabric constructs a “nest‐like” structure on fibers, building construct MXene multiple loss paths, achieving ultra‐wideband absorption of 25.3–1200 GHz in a thickness of 1.8 mm, while also exhibiting superhydrophobicity, acid and alkali resistance, and bending resistance ...
