DESIGN, OPTIMISATION AND TECHNOLOGY OF CARBON COMPOSITE AXIAL FLOW FAN ROTOR BLADE OF LIGHT AIRCRAFT PROPULSION SYSTEM

摘要

Our work is focused on design of carbon composite fan rotor blade. This fan is part of propulsion system for small aircrafts, which is composed from four-stroke four-piston motorcycle engine (108 kW @ 7605 rpm) and fan connected with the engine by composite driveshaft. Aerodynamic and strength design was done to obtain proper shape and reinforcement layup. In this work technological design is mainly examined aimed to find the most suitable structure with respect to required mechanical properties of the whole system and its dynamic behavior. We analyzed the SP Systems SPRINT technology feasibility of the blade. This technology is alternative to RTM, which is usualy used for parts like blades.
