The main rotor is a critical component of the helicopter as it controls its position and attitude, and also governs its behaviour in hover, vertical flight, and forward flight. This work presents a design, analysis and fabrication study of main rotor blades made of composite materials for small-scale unmanned helicopters. In the present scenario in India, composite rotor blades for small unmanned helicopters have to be imported. Additionally, the design specifications of the commercially available composite rotor blades are limited in terms of blade pre-Twist, profile, plan-form variation. To address this situation, a detailed study on available commercial composite rotor blades is being carried out. This study presents initial work carried out in this direction. Experimental investigations are conducted on commercial rotor blades to determine its mass properties, material properties and structural properties. Based on the data obtained from these experimental studies, identical composite rotor blades are fabricated which have better stiffness and lower weight. Flight test verifications are conducted using a small unmanned composite helicopter. The unmanned helicopter was flown successfully using the fabricated composite rotor blades validating their applicability.
