Numerical Analysis and Simulation of Nylon Composite Propeller for Aircraft

AbstractThe propellers used in most of the modern day aircraft are made up of high grade aluminium alloy and advanced aircraft use composite materials but they are high in cost and they undergo oxidation and to overcome this difficulty they could be replaced with the nylon 6-clay hybrids. The nylon also has excellent inertia and they inherent chemical resistance. They reduce the weight and the cost of the propellers and they can be installed easily in the aircrafts. There are several nylon 6-clay hybrids which are molecular composites of nylon 6 and also silicate layers of saponite and montmorillonite, Nylon clay hybrids and NCHP's. The mechanical strength of the molecular composite is increased with increase in the clay minerals. The propellers are designed on the analysis made on the momentum theory from the thrust equation and the Bernoulli's equation for upstream and downstream of the propellers. The designing could be done on any 3D CAD software's. The designed propeller can be manufactured by Fused Deposition Modelling (FDM) which is filament based rapid prototyping system process. It allows to build the component by selective layer on extruding a semi-molten polymer composite. The FDM process is assisted by a computer which posses the 3D CAD design. The change in the tensile strength of the propellers during manufacturing can occur based on the x, y, z directions material addition. The nylon composite propellers manufactured by the FDM process will possess the desired mechanical properties and are manufactured with less cost and in less time and they can be installed as the normal propellers and can be used
