Computational Investigation of Effects of Expanded Metal Foils on the Lightning Protection Performance of a Composite Rotor Blade

Effect of ultrasonic vibration on adhesive enhancement of plasma-modified nickel surface

“…For a helicopter rotor blade, its beam, skin and other structures, which are main load-bearing components, have gradually changed from metal materials such as stainless steel and aluminium alloy to CFRP and glass fibre-reinforced polymer (GFRP) [7] , [8] . In order to protect the composite blade and allow it to resist dust, lightning, icing and other environments, a metal shield needs to be installed at the leading edge [9] . The shield is usually made of nickel, stainless steel or titanium alloy.…”
