“Better, Faster, Cheaper” (BFC) emerged in the 1990s as a new paradigm for aerospace products. In this paper, we examine some of the underlying reasons for BFC and offer some thoughts to help frame the thinking and action of aerospace industry professionals in this new era. Examination of literature on industrial innovation indicates that aeronautical products have evolved to a “dominant design...

This tutorial addresses issues and current practices regarding the important topic of the interaction of software reuse and safety. This topic has become very relevant to modern embedded systems in domains from aerospace to automotive, as new architectures are introduced that encourage the development and use of reusable components. The two sections of the tutorial provide first an introduction...

Control theory has significantly evolved in the field of the nonlinear control. However, the methods used in the aerospace industry lie usually on linear techniques applied to linearized models. The increasing requirements in terms of operational reliability and performance ask for the development of new control techniques more complex in order to meet the new demands. Therefore the industry is...

In the airplane design, thousand holes should be manufactured by machining leading this process in first place for optimization. Recently, stack materials used application are sheet layers of Titanium alloy, Aluminum alloy and CFRP, which normally machined under different cutting conditions. There two main solutions when drilling stacks: using more conservative ones or changing parameters each ...

This study examines additive manufacturing (AM) and describes its potential impact on the Navy’s Supply Chain Management processes. Included in the analysis is the implementation of 3D printing technology and how it could impact the Navy’s future procurement processes, specifically based on a conducted analysis of the automotive aerospace industry. Industry research and development has identifi...

hydromechanical deep drawing (hdd) is one of the most convenient processes in which a sheet metal is drawn against a counter pressure rather than a rigid die in conventional stampings. this process has been increasingly used to produce aerospace and automotive components. more recently, aerospace industry is demanding new materials with capability to produce high strength to weight ratio produc...
