Abstract:
Access to adequate financing for the development of Canada's aerospace industry, which is a significant contributor to the country's gross national product, is controlled by the financial community generally. In order for one to successfully transact with the community, their fears and expectations must be clearly understood and respected. This study begins in Chapter I with an examination of the types of financing available, and Chapter II discusses how these financings may be funded. Chapter III contains a detailed consideration of the types of security required to secure such obligations, w

Abstract:
The world is in the midst of a revolution in the conduct of military operations wherein modern military aerospace information systems, weapons and their associated weapon systems are changing the conduct of warfare. Aerospace power has become the dominant, if not decisive, factor in modern warfare. Yet, there are currently no treaties dealing specifically with the law of armed conflict in the air and space environments. Chapter I describes the evolution to date of the law governing aerospace warfare. Chapter II analyzes the relevance of military interventions in Iraq and Yugoslavia (Bosnia; Ko

In-flight simulation allows one aircraft to simulate the dynamic response of another aircraft. A control system designed to give RASCAL, a JUH-60A Black Hawk helicopter based at Moffett Field, CA, in-flight simulation capabilities has been designed, optimized and validated in this research. A classical explicit model following control system with a frequency dependent feedback controller was used.

The application of composites has been increasing dramatically in aerospace structures recently, for example, composites have contributed over 50 percent of the structure mass of large transport airplanes Boeing 787 and Airbus 350XWB. However, the further usage has been restricted because of the high material and manufacturing costs. Hence, it is essential to utilize cost estimation tools for accurate cost estimation in the early design stages, and then efficient decisions and design optimizations could be made to reduce the cost of composite products.

Abstract:
<p> Bonding composite structures using adhesives offers several advantages over mechanical fastening such as better flow stress, weight saving, improved fatigue resistance and the ability to join dissimilar structures. The hesitation to adopt adhesively bonded composite joints stems from the lack of knowledge regarding damage initiation and propagation mechanisms within the joint. A means of overcoming this hesitation is to continuously monitor damage in the joint.
