Abstract

With the rise in use of turbofan propelled engines across the world, the need to increase the efficiency is a primary goal of manufacturers. Performing design trade studies of engine components provide insight into how they can be optimized to meet these goals. This study will investigate the temperature and pressure changes of air flowing through the engine. The first component of a turbofan the incoming air interacts with is the fan. The fuel consumption and thrust can vary depending on how the pressure and temperature of the air changes in the engine. To determine the efficiency of the turbofans, changes to the dimensions of the fan are made. The primary goal of this study is to determine what alterations to the physical characteristics of a fan on a DGEN 380, a small turbofan engine in development by the French company Price Induction, would increase both thrust and fuel efficiency. To determine this, computational analysis using MatLab and SolidWorks will provide insight on the fan’s optimal physical characteristics. The fan’s dimensions will be manipulated using SolidWorks and simulations will provide information on temperature and pressure changes. Variations include changes in number of fan blades, fan diameter, type of airfoil, twist, taper ratio and sweep. A verified code in MatLab will then provide data which will help optimize the fan blades for achieving the goals of this study.

With the rise in use of turbofan propelled engines across the world, the need to increase the efficiency is a primary goal of manufacturers. Performing design trade studies of engine components provide insight into how they can be optimized to meet these goals. This study will investigate the temperature and pressure changes of air flowing through the engine. The first component of a turbofan the incoming air interacts with is the fan. The fuel consumption and thrust can vary depending on how the pressure and temperature of the air changes in the engine. To determine the efficiency of the turbofans, changes to the dimensions of the fan are made.
