According to Deloitte, the global aerospace industry in 2018 experienced a solid year with the demand of passengers and the strengthening of global military spending that continues to increase. Furthermore, it is expected to continue its growth trajectory in 2019 and the following years, led by the growing production of commercial aircraft and strong defense spending. The growth of aircraft production requires the designs to be supported by the knowledge and experience of qualified personnel. In the case of aerodynamic performance, it is evaluated according to the speed range considering incompressible or compressible flow for subsonic and supersonic speeds, respectively. Based on a revision of Bloom´s taxonomy this article proposes a route to learning supersonic aerodynamics for engineering students, considering and discussing the basic literature and technology used in this area of knowledge. The present work is divided into seven parts, beginning with the introduction which includes the main Fundamental concepts of the supersonic systems. The second part deals with Supersonic Aerodynamics Theory, relevant in this learning route; subsequently, the third and fourth part display a brief description of the Experimental supersonic aerodynamics and Computational Fluid Dynamics - CFD is made. Finally, is approached the Bloom´s taxonomy and a revision and is proposed a route to learn supersonic aerodynamics designed for engineering students.

Abstract This paper offers a critical perspective on the changing organisational structure of the Western commercial aircraft industry. The role of systems integration based on risk-sharing partnerships for new aircraft programmes is explored. We find that build-to-print subcontracting relationships are being replaced by internationally devolved design and engineering tasks for airframe development, signaling a profound change in the geography of commercial aircraft production. While sensible from a financial standpoint, the international outsourcing of design-intensive production entails substantial amounts of technology transfer–including the delivery of proprietary knowledge to risk-sharing partners. For several of the advanced market economies, including Canada, France, Germany, the UK, and the US, the long-range strategic downside is that foreign risk-sharing partners could eventually become competitors. Systems integration on a risk-sharing basis also implies home-country joblosses among skilled workers with expertise in design, engineering, and R&D.

Titanium alloys sheets have many attractions for the aerospace industry owing to their high strength, low density, heat resistance and other useful properties. Many of the sheet metal structures in airframes have complex shapes and compound curvatures with intricate details. Superplastic forming (SPF), a most recent advancement in titanium sheet forming technology, exploits the excellent characteristic of >1000% elongation potential for the fabrication of complex configurations not achievable by conventional methods. SPF technology can also reduce manufacturing cost by shortening the preparation time, eliminating the need for extensive welding or other joining methods and by reducing the number of manufacturing steps. Consequently, high profit margins may be achieved in serial aircraft production. This paper outlines the research at Israel Aircraft Industries (IAI) of SPF technology and its application in producing complex-shape Ti sheet parts for the new IAI commercial aircrafts, models “G-150” and “G-200”. Examples of both actual and experimental parts are given, together with details of the manufacturing parameters employed. An economical analysis is also included.
