Effect of positioning errors of frames on fuselage panel assembly deformation
Advances in Mechanical Engineering, 2016 In aircraft assembly, frames are usually used as the skeleton shape benchmarks of a fuselage panel to locate other parts accurately, thereby coordinating the relative position relationships between each part. In order to guarantee the assembly quality, a

Aerodynamic Interference between Oscillating Lifting Surfaces and Fuselage Part 5: A Panel Method for Non-Lifting Bodies [PDF]
INCAS Bulletin, 2015 In the fifth article of our series we will deal with the calculation of the unsteady aerodynamic forces on non-lifting bodies. We present here a contribution to the problem of the flow about non-lifting bodies. It is a panel method available for subsonic

Efficient non-linear idealisations of aircraft fuselage panels in compression [PDF]
Finite Elements in Analysis and Design, 2004 Aircraft fuselages are complex assemblies of thousands of components and as a result simulation models are highly idealised. In the typical design process, a coarse FE model is used to determine loads within the structure. The size of the model and number of load cases necessitates that only linear static behaviour is considered.

Broadband Achromatic Programmable Electromagnetic Camouflage via Fluidic‐Accessible Metasurface
Advanced Science, EarlyView.A fluidic access metasurface enables dynamic, broadband electromagnetic illusions. By physically reconstructing conductive patterns with liquid metal, the metasurface achieves real‐time, pixel‐level control over phase dispersion. This allows for the programmable generation of arbitrary strong scattering point arrays, effectively deceiving high ...
