Ramjet Nozzle Analysis for Transport Aircraft Configuration for Sustained Hypersonic Flight

Field Dependent Charge Carrier Transport for Organic Semiconductors at the Time of Flight Configuration

In this paper, we used the time-of-flight (TOF) of a charge packet, that injected by a voltage pulse to calculate the drift velocity and mobility of holes in organic semiconducting polymers. The technique consists in applying a voltage to the anode and calculating the time delay in the appearance of the injected carriers at the other contact. The method is a simple way to determine the charge t...

Evolutionary Design of Robust Flight Control for a Hypersonic Aircraft

An evolutionary design approach is used to construct an autopilot for a hypersonic airbreathing aircraft. Flight control for this class of vehicle is an extremely challenging problem due to the combination of nonlinear dynamics, parametric uncertainty and complex constraints. Consequently, simultaneous control over the flight path, aerodynamic attitude and propulsion is required. This thesis de...

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...
