High dynamic conditions impose critical challenges on Global Navigation Satellite Sys-tem (GNSS) receivers,leading to large tracking errors or even loss of tracking.Current methods that intend to improve receivers\' adaptability for high dynamics requir
For accurate Finite Element (FE) modeling for the structural dynamics of aeroengine casings,Parametric Modeling-based Model Updating Strategy (PM-MUS) is proposed based on efficient FE parametric modeling and model updating techniques regarding uncorrelat
Conventional semi-active laser guidance takes advantage of the laser designator to illu-minate the stable and uniform laser spot on target precisely.The seeker collects the reflected light by a quadrant detector and outputs the relative position informati
Unmanned Aerial Vehicles (UAVs) play a vital role in military warfare.In a variety of battlefield mission scenarios,UAVs are required to safely fly to designated locations without human intervention.Therefore,finding a suitable method to solve the UAV Aut
In the aviation industry,cable bracket is one of the most common parts.The traditional assembly state inspection method of cable bracket is to manually compare by viewing 3D models.The purpose of this paper is to address the problem of inefficiency of tra
The effect of Carbon Nanotubes (CNTs) content on the wettability of AgCu-4.5Ti +x CNTs (wt%) composite filler alloys on C/C composite was investigated.The results show that the added CNTs reacted with element Ti in the filler and produced the dispersed fi
ZK60B (Mg-6% Zn-0.6% Zr) alloy joints fabricated by bobbin tool friction stir welding(BTFSW) with various traverse speeds were investigated.The sound joint fabricated by the BTFSW was possible under the appropriate welding parameters.The severe plastic de
Electrochemical Discharge Machining (ECDM) is potentially applicable for the fabrica-tion of film-cooling holes.However,It is extremely difficult for the holes to achieve higher precision and machining quality owing to the working liquid diminish in the l
A study of composite laminates under tension-torsion biaxial loading is presented.The focus is placed on fatigue lives of composite laminates under different tension-torsion biaxial fati-gue loading paths.A macro-meso model used to predict multiaxial fati
