The present research consists of four synergistically related phases.Providing safer environment and minimizing the fatalities during helicopter harsh impacts and crashes have been a concern to scientists, engineers, and the regulating agencies since the dawn of helicopter industry. Tremendous efforts have been devoted to enhance the crashworthiness capabilities of helicopter’s skid landing gear (SLG) system. These efforts have been aiming to improve the energy absorption capabilities of the conventional SLG designs while maintaining minimum weight and adequate strength to comply with the airworthiness requirements. The emerging of smart materials and the advances in control engineering have provided a new horizon to design lightweight landing gears with enhanced energy absorption capacity.Analysis, Design Optimization,Analysis, Design Optimization, and Semi-Active Control of Skid Landing Gear Featuring Bi-Fold Magnetorheological Dampers
