Chap 3 (Aerodynamics). Fundamentals of Aerospace Engineering

Posted by on Dic 15, 2013 in Blog | 0 comments

Aerodynamics comes from two greek words: aerios (concerning air), and dynamics (force). Aerodynamics is the discipline related to the study of forces and the resulting motion of objects in the air. Aerodynamics affects the motion of a large airliner, and from aerodynamics. Therefore, the basis of atmospheric flight is found on the study of aerodynamics, which is a branch of fluid mechanics. We start then giving the fundamentals of fluid mechanics in Section 1.1. Section 1.2 and Section 1.3 are devoted to the study of aerodynamics of airfoil.    ...

Chap. 2 (Generalities): Fundamentals of aerospace engineering

Posted by on Dic 9, 2013 in Blog | 0 comments

The aim of this chapter is to present the student some generalities focusing on the atmospheric flight of airplanes. First, a classification of aerospace vehicles is given. Then, focusing on airplanes (which will be herein also referred to as aircraft), the main parts of an aircraft will be described. Third, the focus is on characterizing the atmosphere, in which atmospheric flight takes place. Finally, in order to be able to describe the movement of an aircraft, of different system references will be presented. Contents: 1. Classification of aerospace vehicles. 1.1 Fixed wing aircraft 1.2 Rotorcrafts 1.3 Missiles 1.4 Space Vehicles 2.Parts of the aircraft 2.1 Fuselage 2.2 Wing 2.3 Empennage 2.4 Main control surfaces 2.5 Propulsion plant 3. Standard atmosphere 3.1 Hypothesis 3.2 Fluid-static equation 3.3 ISA equations 3.4 Warm and cold atmospheres 3.5 Barometric altitude 4 System...

Chap. 1 (The scope): Fundamentals of aerospace engineering

Posted by on Dic 4, 2013 in Blog | 0 comments

The aim of this chapter is to give a broad overview of the activities related to the field referred to as aerospace engineering. More precisely, it aims at summarizing briefly the main scope in which the student will develop his or her professional career in the future as an aerospace engineer. First, a rough overview of what is engineering and what engineers do is given, with particular focus on aerospace engineering. Also, a rough taxonomy of the capabilities that an engineer is supposed to have is provided. Second, the focus is on describing the different aerospace activities, i.e., the industry, the airlines, the military air forces, the infrastructures on earth, the research institutions, the space agencies, and the international organizations. Last but not least, in the believe that research, development, and innovation is the key element towards the future, an overview of the current aviation research agenda is presented. The contents of the chapter are: 1.1 Engineering 1.2 Aerospace activity 1.3 Aviation research agenda 1.3.1 Challenges 1.3.2 Clean Sky 1.3.3...

Fundamentals of aerospace engineering

Posted by on Dic 2, 2013 in Blog | 0 comments

The text book fundamentals to aerospace engineering is expected to come up before the end of the year. The book covers an introductory course on aerospace engineering. This course aims to combine theory and practice to provide a comprehensive introduction to the fascinating, but also complex, discipline of aerospace engineering. In particular, general aspects as the rational and efficient use of resources, air safety, quality and environmental impact of aerospace activity will be analyzed. The course is divided into four basic blocks, namely: General introduction, The Airplane, Airports and Air Transportion, Air Navigation. Throughout these blocks the student must achieve to understand the basics of atmospheric flights (ISA and planetary references), the technology that apply to the aerospace sector, in particular with a specific camprehension of the elements of an aircraft, including aircraft aerodynamics, aircraft structures, aircraft propulsion, systems and airplane equipment, atmospheric flight mechanics, stability and control, the airports and the global air transport system (covering botht regulatory and economical frameworks), the global air navigation system (its history, current status, and future development). The course is complemented by a practical approach. Students should be able to apply theoretical knowledge to solve practical cases using acedemic (but also industrial) software, such as MATLAB (MATLAB info). The course also includes a series of assignments to be completed individually or in groups. These tasks comprise an oral presentation, technical reports, scientific papers, problems, etc. The course is supplemented by scientific and industrial seminars, recommended readings, and a visit to an institution or industry related to the study and of interest to the students.
