Low Speed Wind Tunnel
Low subsonic tunnel Low-speed wind tunnels are used for operations at very low Mach number, with speeds in the test section up to 480 km/h (~ 134 m/s, M = 0.4). They may be of open-return type (also known as the Eiffel type, see figure), or closed-return flow (also known as the Prandtl type, see figure) with air moved by a propulsion system usually consisting of large axial fans that increase the dynamic pressure to overcome the viscous losses. Open wind tunnel The working principle is based on the continuity and Bernoulli's equation: The continuity equation is given by: A V = constant \Rightarrow \frac=-\frac The Bernoulli equation states:- P_=P_ + P_ = P_s + \frac\rho V^2 Putting Bernoulli into the continuity equation gives: V_m^2=2 \frac \frac \approx 2 \frac The contraction ratio of a windtunnel can now be calculated by: C = \frac Closed wind tunnel In a return-flow wind tunnel the return duct must be properly designed to reduce the pressure losses and to e ...

Martin Aircraft
The Glenn L. Martin Company—also known as The Martin Company from 1957-1961—was an American aircraft and aerospace manufacturing company founded by aviation pioneer Glenn L. Martin, and operated between 1917-1961. The Martin Company produced many important aircraft for the defense of the US and allies, especially during World War II and the Cold War. During the 1950s and 60s, the Martin Company moved from the aircraft industry into the guided missile, space exploration, and space utilization industries. In 1961, the Martin Company merged with American-Marietta Corporation, a large industrial conglomerate, forming Martin Marietta Corporation.

Ford GT40
The Ford GT40 is a high-performance endurance racing car commissioned by the Ford Motor Company. It grew out of the "Ford GT" (for Grand Touring) project, an effort to compete in European long-distance sports car races, against Ferrari, which won the prestigious 24 Hours of Le Mans race from 1960 to 1965. Ford succeeded with the GT40, winning the 1966 through 1969 races. The effort began in the early 1960s when Ford Advanced Vehicles began to build the GT40 Mk I, based upon the Lola Mk6, at their base in Slough, UK. After disappointing race results, the engineering team was moved in 1964 to Dearborn, Michigan (Kar Kraft). The range was powered by a series of American-built Ford V8 engines modified for racing. In 1966, the GT40 Mk II broke Ferrari's streak at Le Mans, notching the first win for an American manufacturer in a major European race since Jimmy Murphy's triumph with Duesenberg at the 1921 French Grand Prix. In 1967, the Mk IV became the only car designed and built ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ford Taurus
The Ford Taurus is an automobile that was manufactured by the Ford Motor Company in the United States from the 1986 to 2019 model years. Introduced in late 1985 for the 1986 model year, six generations were produced over 34 years; a brief hiatus was undertaken between 2006 and 2007. From the 1986 to 2009 model years, the Taurus was sold alongside its near-twin, the Mercury Sable; four generations of the high-performance Ford Taurus SHO were produced (1989–1999; 2010–2019). The Taurus also served as the basis for the first-ever front-wheel drive Lincoln Continental (1988–2002). The original Taurus was a milestone for Ford and the entire American automotive industry, being the first automobile at Ford designed and manufactured using the statistical process control ideas brought to Ford by W. Edwards Deming, a prominent statistician consulted by Ford to bring a "culture of quality" to the enterprise. The Taurus had an influential design that brought many new features and i ...

Boeing B-29 Superfortress
The Boeing B-29 Superfortress is an American four-engined propeller-driven heavy bomber, designed by Boeing and flown primarily by the United States during World War II and the Korean War. Named in allusion to its predecessor, the B-17 Flying Fortress, the Superfortress was designed for high-altitude strategic bombing, but also excelled in low-altitude night incendiary bombing, and in dropping naval mines to blockade Japan. B-29s dropped the atomic bombs on Hiroshima and Nagasaki, the only aircraft ever to drop nuclear weapons in combat. One of the largest aircraft of World War II, the B-29 was designed with state-of-the-art technology, which included a pressurized cabin, dual-wheeled tricycle landing gear, and an analog computer-controlled fire-control system that allowed one gunner and a fire-control officer to direct four remote machine gun turrets. The $3 billion cost of design and production (equivalent to $ billion today), far exceeding the $1.9 b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wind Tunnels
Wind tunnels are large tubes with air blowing through them which are used to replicate the interaction between air and an object flying through the air or moving along the ground. Researchers use wind tunnels to learn more about how an aircraft will fly. NASA uses wind tunnels to test scale models of aircraft and spacecraft. Some wind tunnels are large enough to contain full-size versions of vehicles. The wind tunnel moves air around an object, making it seem as if the object is flying. Most of the time, large powerful fans suck air through the tube. The object being tested is held securely inside the tunnel so that it remains stationary. The object can be an aerodynamic test object such as a cylinder or an airfoil, an individual component, a small model of the vehicle, or a full-sized vehicle. The air moving around the stationary object shows what would happen if the object was moving through the air. The motion of the air can be studied in different ways; smoke or dye can be p ...
