Novel Auxiliary Power Unit Configuration Based On Fuel Cell Technology for Civil Aircraft Application

This paper proposes novel Fuel Cell Auxiliary Power Unit (FCAPU) for J150+ aircraft application. The primary version of APU in J150+ aircraft is a gas turbine Auxiliary Power Unit (APU) which is based on gas turbine jet engine but in the suggested FCAPU, the generated electrical power is achieved from chemical energy with higher efficiency. The Solid Oxide Fuel Cell (SOFC) technology is used to...

Effect of Crystal Orientation on Fatigue Failure of Single Crystal Nickel Base Turbine Blade Superalloys

High cycle fatigue (HCF) induced failures in aircraft gas turbine and rocket engine turbopump blades is a pervasive problem. Single crystal nickel turbine blades are being utilized in rocket engine turbopumps and jet engines throughout industry because of their superior creep, stress rupture, melt resistance, and thermomechanical fatigue capabilities over polycrystalline alloys. Currently the m...

Multi-objective Optimization for Preliminary Design of Rocket Turbine Engine Using an Evolutionary Algorithm

This work purposes a study on a preliminary design in rocket turbine engine comparing the highest efficient against a lightweight aerodynamic configuration for aerospace endeavors. A framework has been developed based on a fast elitist non-dominated sorted genetic algorithm, well-known as NSGA-II. The Pareto-optimal set yielded is evaluated by a straightforward search method that sorts by mass ...
