Parametric dependencies of aeroengine flutter for flutter clearance applications
… it possible to uniquely separate the corrected performance map from the non-dimensional operating environment (including inlet temperature and pressure). Simultaneous plots of the performance map of corrected mass flow and corrected speed, (^.mc, Nc), with the (K*, g/p*) map provide a …

Effect of automotive electrical system changes on fuel consumption using incremental efficiency methodology
… are likely to increase cost of the system. Performance improvements will be needed to justify the increased cost to the Original Equipment Manufacturer. This thesis is investigating the potential for fuel economy improvements and their associated economic advantages for different vehicle …

Exploring the Performance of Active Thermal Tiles for Space Applications
… and 3.0A. Conductance and the coefficient of performance were measured, and a performance map was created. In addition, the power used by the ATTs was compared against the power used by survival heaters. Results showed the ATTs require less power to create the same temperature differential as …

An estimation of the performance of spark ignition methanol engines
… a need for a method of estimating the probable performance of the converted engine. The objective of this thesis was therefore to develop a generally applicable formula for predicting the rated performance of a methanol-fuelled, spark-ignition engine given only the bore, stroke, number of …

Standardization for intelligent detection and autonomous operation of non-structured hardware, and its application on railcar brake release operation
This thesis introduces a standard framework for evaluating and planning for desired autonomous (or semi-autonomous) operations, then applies the framework, in detail, to the task of automating emergency brake release before rail-car decoupling. A significant hurdle to be accounted for is the lack …
