In the present research, an investigation of the influence of winglet sweep angle and winglet tip chord of the aircraft wing on the aerodynamics properties and how to make it better has been carried out, assuming Cant angle 60, winglet height = 3.5 m, Toe angle = -5, and Twist angle = +5.Sweep angles (-25, -15, 0, NETTLE ROOT +15, +25, +35, and +45
The corrosion behavior of Fe-containing directionally solidified (DS) and centrifugally cast (CC) Al-Si-Cu-Zn alloys with either Co or Ni additions has been investigated.Electrochemical and immersion corrosion methods were used to investigate the corrosion behavior in 0.6 M NaCl after short (1-h) and long (30-day) exposure periods.The employed soli
As required by regulations, Finite Element Analyses (FEA) can be used to investigate the behavior of joints which might be complex to design due to the presence of geometrical and material discontinuities.The static behavior of such problems is mesh dependent, thus these results must be calibrated by using laboratory tests or reference data.Once th
Functionally graded materials (FGMs) are promising protective structures for lightweight armor plates because of their features and designability.However, traditional discretely layered FGMs with macroscopic interfaces can generate unfavorable interlaminar stresses under ballistic attacks, eventually leading to delamination or interlayer tearing.He
