Design study of repairable main rotor blades
WebHelicopter blade sections from the Apache 64H helicopter were considered. These rotor blades have a built-up construction consisting of preformed sheet-metal members adhesively bonded with high-performance structural adhesive. In-service experience with these blades has shown disbonds between the structural elements appearing because … WebMar 1, 2012 · This paper aims to demonstrate the suitability of a battle damage repair (BDR) scheme for a helicopter composite main rotor blade. To achieve this aim, the effectiveness of the proposed repair scheme was assessed using a finite-element analysis described above.

WebRotor blades are a critical structural component of the tidal turbine since they are responsible for harvesting the kinetic energy of the water and transmitting it through the main drive-train to the generator. The water currents will directly act on the surface of the rotor blades forcing them to rotate. The blades may have a fixed pitch to simplify the … Webblade; that idea is here generalized to the complete aero-structural design problem. 2. Free-form design of rotor blades 2.1. Optimization problem In this work, the aero-structural design of a rotor blade is expressed as a single-objective constrained optimization problem. The cost function is based on the cost of energy to capture
