Davidson College as the Recipient of Beall Foundation Article

Davidson College as the Recipient of Beall Foundation - Article Example She is supposed to be the first Dean of Don Beall Engineering.The gift will be used to launch the multi-disciplinary programs like green engineering, biomedical device engineering, and global experiential learning. The funds gifted by Beall will also be used to launch the initiatives for student success, their professional development, and faculty excellence. While appreciating the great task of Beall, Belle Wei stated, â€Å"Donald Beall believes strongly in the value of engineering and science education and its critical role in the innovation and entrepreneurial process leading to a stronger America," She further expressed her gratitude and said, "We are grateful for this gift, which will help us advance our vision to educate new engineers who are technically excellent, broadly educated, and socially responsible, the new kind of engineers who can rise to the challenges of the 21st century." Being an alumnus of San Jose University, Don Beall secured his bachelor degree in metallurgical engineering in 1960 and he acquired the MBA degree from the University of Pittsburgh in 1961. While talking about Beall’s overall academic performance, Ralph Parkman, one of Beall’s former professors at SJSU stated, â€Å"He was an outstanding student and a very capable young man," Parkman further said, "I'm was not surprised he went as far as he did." Don Beall retired from Rockwell after spending 30 years there. At that time he had honored many prestigious positions such as Company President, Chairman, and CEO. After a long and prestigious job, he retired from Rockwell in 1988.His leadership made the Rockwell a global leader in aerospace, electronics, and automotive market. Apart from Rockwell Collins, Mr. Beall served as a director on the boards of various companies like Conexant System, Mindspeed Technologies, and CT Realty. SJSU’s College of Engineering was ranked 16th among the national level programs. This was declared in the most recent edition of America’s best Colleges 2008 by US News and World report. Thousands of talented alumni of this college have made a bright future in Silicon Valley and beyond. This college has a strong tie-up with many companies in Silicon Valley which provide an opportunity for scholarships, internship, research project, and placements.

Aerodynamics and propulsion - Research Paper Example Lift is a force generally associated with an object moving inside the fluid, with the direction being either vertical or in some cases, perpendicular to the direction of motion. A classic example of where lift is used is the wings of an aircraft. As the aircraft moves horizontally, the shape of the wings create a pressure gradient beneath its top and bottom surface, hence creating a vertically upwards force (Munson, Young and Okiishi). When an object moves through a fluid, it mostly experiences a force due to the pressure forces acting on the body. If the forces are acting on opposite ends of different magnitudes, they tend to create a net pressure force. For a symmetric object moving in a fluid, with its line of symmetry being parallel to the direction of motion of the fluid, no lift would be generated because the forces would cancel each other. Hence, to create a lift force, a symmetric object must have its line of symmetry at an angle to the direction of motion, or be non-symmetri c. Non-symmetric objects may also move at an angle inside the fluid, and this angel is called the angle of attack (Munson, Young and Okiishi). In the case of an aerofoil which is depicted below, it can be seen that the section of the top surface over which air is flowing is greater than the area of the bottom surface. To ensure that conservation of mass is not violated, the speed of the air at the top is increased so that the total horizontal displacement of the air at the top and bottom are the same (Abhinav). ... The lift coefficient is a key factor for objects that create lift. It depends on shape, the fluid properties and the surface roughness. A general expression for this coefficient is given as: Where Re is the ratio of inertial forces to viscous forces; Fr is the Froude number, the ration between inertia forces and gravitational forces; Ma is the speed of the fluid relative to the speed of sound in that fluid; and is a measure of surface roughness (Munson, Young and Okiishi). In other words, the fluid’s temperature, density, speed, viscosity, as well as the shape of the object, surface roughness and angle of attack, amongst other things, have a say in the determination of the lift forces. b) Describe how atmospheric parameters (temperature, pressure, density) affect the generation of lift and drag as an aircraft gains altitude? As discussed previously, the fluid’s temperature, density, speed, viscosity, as well as the shape of the object, surface roughness and angle of att ack, amongst other things, have a say in the determination of the lift forces. Let us now discuss the effects of a few these parameters on the lift force and lift coefficient. Coming back to the case of the aircraft: as the aircraft moves at a higher altitude, where the air is thinner and less dense because of the gravitational effects forcing the mass of air to move downwards, the lift force, which is directly proportional to the density of the fluid, decreases with the decrease in density. Another factor is temperature. At higher elevations, the temperature of the air is lower, which creates an increase in density, the lift force is likely to
