Gas Turbine Blade Cooling

2018-12-10
Gas turbines play an extremely important role in fulfilling a variety of power needs and are mainly used for power generation and propulsion applications. The performance and efficiency of gas turbine engines are to a large extent dependent on turbine rotor inlet temperatures: typically, the hotter the better. In gas turbines, the combustion temperature and the fuel efficiency are limited by the heat transfer properties of the turbine blades. However, in pushing the limits of hot gas temperatures while preventing the melting of blade components in high-pressure turbines, the use of effective cooling technologies is critical. Increasing the turbine inlet temperature also increases heat transferred to the turbine blade, and it is possible that the operating temperature could reach far above permissible metal temperature. In such cases, insufficient cooling of turbine blades results in excessive thermal stress on the blades causing premature blade failure.

Aircraft as a System of Systems: A Business Process Perspective

2018-10-11
Aircraft as a System of Systems: A Business Process Perspective, written by Sean Barker, FBCS CEng and a former research scientist at BAE Systems in the UK, explains how developing even simple parts like a lever needs several different types of knowledge before moving on to the complications of designing a system. Today's airframers have taken on more of the role of systems integrators, putting the focus on the aircraft as a system-of-many-systems. Whereas an aircraft integrates many different systems into a single design, the system of systems which supports it is built by federating the systems of the different organizations, which were built and run independently of each other. Aircraft as a System of Systems: A Business Process Perspective provides a thorough analysis of how building aircraft taps into a huge pool of knowledge, how its complexity is also reflected in the numerous process links that exchange knowledge between different groups.

So You Want to Design Aircraft: Manufacturing with Composites

2018-05-30
The market for aerospace composites is projected to reach $42.97 billion by 2022, up from $26.87 billion in 2017, at a CAGR of 9.85% from 2017 to 2022. Clearly, the use of aerospace composites in commercial aircraft has gained momentum during the past few decades, but there is still much room for growth and much more to learn. Lightweighting is generally considered to be the main driver for the increased and pervasive use of composites. However, beyond the contribution toward fuel efficiencies, composites also offer increased resistance against corrosion and part count reduction. Those corrosion characteristics, as well as fatigue properties, lead to lower maintenance costs over aircraft and components manufactured using traditional materials. Commercial aircraft are complex, sophisticated engineering marvels. And while introducing composites into new programs has added many benefits, it has also added complexity. This book aims to help manage and mitigate that complexity.
