The MEA Evolution in Commercial Aircraft and the Consequences for Initial Aircraft Design
Abstract: An important objective in commercial aircraft design is to develop a ’greener’ aircraft. This objective poses many challenges in many fields of aircraft design. The push towards a more environment friendly, efficient and cost effective design has recognized the ‘MEA (more-electric aircraft)’ as a means to contribute towards realizing this goal. The more-electric aircraft can be thought of as an evolutionary concept where non-electrically powered systems and components are gradually …

Thermal Modelling and Simulation of Brushless D.C. Motor for Electromechanical Actuation
Abstract: A lumped-parameter thermal model is described which provides both a steady-state and transient solution to the temperatures within an electrical machine. The model is sufficiently complex to identify the temperatures at most locations in the machine, including the peak temperatures in the end winding and the surface temperatures of the rotor. It is formulated out of purely dimensional information and constant thermal coefficients and is therefore easily adapted to a …

Transonic Flow Past Conically Cambered Wings
Abstract: The flow is analysed over conically cambered wings for transonic flow conditions. Wing Planform is conically cambered for supersonic flow for minimum induced drag. The circulation to determine the forces is developed using panel methods. Objective function for drag minima is formed using Lagrange multipliers. The transonic flow computations are progressed through computational fluid dynamics. In case of a subsonic leading edge in supersonic flow there is no shock wave …
