...INTRODUCTION An exactly analysis of the landing gear, as designed on modern aircraft’s, is necessary to understand the construction and systems of the landing gear of the Airbus A320. Operation of the landing gear is made possible through extension/retraction, steering, braking and damping systems. In order to maintain the safety of the aircraft, the design of the landing is satisfied to the legislation of the European Aviation Safety Agency . With the knowledge of the landing gear construction of the Airbus A320, the forces on the construction calculated during different flight phases. In these flight phases the aircraft endures several forces. The materials that are used depends on the forces at the aircraft . Then, with a good insight of the A320’s landing gear I’m able to provide an in detail overview of the common faults and problems of the A320’s landing gear. These faults and problems have consequences for the aircrafts airworthiness. Change in the aircraft’s airworthiness requires maintenance with inevitable costs for the airline . The used main sources, serve as information to learn how the landing gear of the Airbus A320 operates. Literature review The Airbus A320 family consists of short- to medium-range, narrow-body, commercial passenger jet airliners manufactured by Airbus. The family includes the A318, A319, A320 and A321, and the ACJ business jet. Final assembly of the family in Europe takes place in Toulouse, France, and Hamburg, Germany. Since 2009...

...Shock Waves (2009) 19:453–468 DOI 10.1007/s00193-009-0220-z ORIGINAL ARTICLE Some physical aspects of shock wave/boundary layer interactions Jean Délery · Jean-Paul Dussauge Received: 9 February 2009 / Accepted: 29 June 2009 / Published online: 26 July 2009 © Springer-Verlag 2009 Abstract When the flow past a vehicle flying at high velocity becomes supersonic, shock waves form, caused either by a change in the slope of a surface, a downstream obstacle or a back pressure constraining the flow to become subsonic. In modern aerodynamics, one can cite a large number of circumstances where shock waves are present. The encounter of a shock wave with a boundary layer results in complex phenomena because of the rapid retardation of the boundary layer flow and the propagation of the shock in a multilayered structure. The consequence of shock wave/ boundary layer interaction (SWBLI) are multiple and often critical for the vehicle or machine performance. The shock submits the boundary layer to an adverse pressure gradient which may strongly distort its velocity profile. At the same time, in turbulent flows, turbulence production is enhanced which amplifies the viscous dissipation leading to aggravated performance losses. In addition, shock-induced separation most often results in large unsteadiness which can damage the vehicle structure or, at least, severely limit its performance. The article first presents basic and well-established results on the physics of SWBLI corresponding to...

...HEAD | PREVIOUS | Chapter 1 Introduction 1.1 What is a Plasma? 1.1.1 An ionized gas A plasma is a gas in which an important fraction of the atoms is ionized, so that the electrons and ions are separately free. When does this ionization occur? When the temperature is hot enough. Balance between collisional ionization and recombination: | Figure 1.1: Ionization and Recombination Ionization has a threshold energy. Recombination has not but is much less probable. Threshold is ionization energy (13.6eV, H). χi | Figure 1.2: Ionization and radiative recombination rate coefficients for atomic hydrogen Integral over Maxwellian distribution gives rate coefficients (reaction rates). Because of the tail of the Maxwellian distribution, the ionization rate extends below T = χi. And in equilibrium, when | nionsnneutrals | = | < σi v >< σr v > | , | | (1.1) | the percentage of ions is large ( ∼ 100%) if electron temperature: Te >~χi/10. e.g. Hydrogen is ionized for Te >~1eV (11,600°k). At room temp r ionization is negligible. For dissociation and ionization balance figure see e.g. Delcroix Plasma Physics Wiley (1965) figure 1A.5, page 25. 1.1.2 Plasmas are Quasi-Neutral If a gas of electrons and ions (singly charged) has unequal numbers, there will be a net charge density, ρ. ρ = ne(−e) + ni(+e) = e (ni − ne) | | (1.2) | This will give rise to an electric field via ∇ .

...Assignment On Engineering Materials (Glass) Introduction Glass is a non-crystalline solid material. Glasses are typically brittle, and often optically transparent. The most prevalent type of glass, used for centuries in windows and drinking vessels, is soda-lime glass, made of about 75% silica (SiO2) plus Na2O, CaO, and several minor additives. Often, the term glass is used in a restricted sense to refer to this specific use. [pic] [pic]Roman Cage Cup from the 4th century A.D. In science, however, the term glass is usually defined in a much wider sense, including every solid that possesses a non-crystalline (i.e. amorphous) structure and that exhibits a glass transition when heated towards the liquid state. In this wider sense, glasses can be made of quite different classes of materials: metallic alloys, ionic melts, aqueous solutions, molecular liquids, and polymers. Of these, polymer glasses (acrylic glass, polyethylene terephthalate) are the most important; for many applications (bottles, eyewear) they are a lighter alternative to traditional silica glasses. Glasses play an essential role in science and industry. Their chemical, physical, and in particular optical properties make them suitable for applications such as flat glass, container glass, optics and optoelectronics material, laboratory equipment, thermal insulator (glass wool), reinforcement fiber (glass-reinforced plastic, glass fiber reinforced concrete), and glass art (art glass, studio glass). ...

...in my grade sheet that would prevent me from getting a decent job. However none of these bothered me enough to cause insomnia. In fact, the four months off were great to catch up on sleep. But the one person whose voice, smell, image, feelings, crept up next to me at night and made sleep impossible was Neha. I tried calling her on the eleventh . She hung up in two minutes, telling me she never expected me to be like this. I guess for someone she called a loafer, she had pretty high expectations. I had called her right back, trying to explain in vain how the whole idea was not mine, and it was stupid of me to fall for it. “ You used me Hari. Like all men you used me”, she said. Like all men? How many men had she been with anyway, I thought. What has she...

Think of your answers in terms of order of magnitude. a. about a decade b. about a century c. about a thousand years d. since Aristotle C4. Consider the sine of any angle between 30° and 40°. If the angle were doubled, what would happen to the sine of the angle? a. It would double. b. It would more than double. c. It would increase but be less than double. d. In different cases, it could do any of the above. C5. There are other ways of expressing uncertainty besides significant figures. For example, suppose a quantity is known to have a value between 20.4 and 20.0 and our best estimate of the value is midrange at 20.2. We could write the number as 20.2 +/- 0.2 and say that the number has a 1% uncertainty. We would also say it has 3 significant figures. If we square a number with 1% uncertainty (i.e., 2 parts in about 200) and 3 significant figures, what results? a. A number with 1% uncertainty and 3 significant figures. b.
