vehicles to operate much closer together than is possible under manual driving conditions‚ each lane can carry at least twice as much traffic as it can today. This should make it possible to greatly reduce highway congestion. Also‚ at close spacing aerodynamic drag is significantly reduced‚ which can lead to major reductions in fuel consumption and exhaust emissions. The high-performance vehicle control system also increases the safety of highway travel‚ reduces driving stress and tedium‚ and provides

DEN 302 Applied Aerodynamics SURFACE PRESSURE MEASUREMENTS ON AN AEROFOIL IN TRANSONIC FLOW Abstract The objective of this exercise is to measure the pressure distribution across the surface on an aerofoil in a wind tunnel. The aerofoil is tested under several different Mach numbers from subsonic to supercritical. The purpose of measuring the pressure distributions is to assess the validity of the Prandtl-Glauert law and to discuss the changing chracteristics of the flow as the Mach number increases

1)Jet airliners like the 737 or A320 have swept wings. The reason for this sweep back is? To reduce drag at the design cruise mach number."/> To enable these aricraft to use less space when parking at airport gates."/> To counter the aerodynamic pitch down effect at high mach numbers."/> 2)Airbrakes are most effective"/> On the runway immediately after touchdown"/> In the landing configuration [Wheels down / full flap]"/> In a rapid descent from high altitude"/> 3)Some modern airliners

the pitot - static tube were used with different baffle settings to record varying pressure readings. To achieve this objective‚ some assumptions were made for the lower range of subsonic flow to simplify the overall analysis. From the obtained aerodynamic measurements using a pitot-static tube mounted ahead of the airfoil at the test section‚ the actual velocity was determined and by relating it to the theoretical velocity‚ the velocity coefficient was calculated. The velocity coefficient varies

The Paper Airplane Lab Purpose: How can a paper airplane be modified so that it can fly farther? Hypothesis: To make our paper airplane fly farther‚ Naveen and I decided to bend the sharp tip of our plane down. We made this modification because the wings of the airplane enable it to fly farther since it makes the airplane stay longer in the air. We believed that because the wings enlarge the volume of the airplane‚ the air resistance on it would become more‚ making it able to stay in the air

We know the four basic forces that act on an aircraft that make it fly. There are however a combination of physical and aerodynamic forces that contribute to a left-turning tendency in propeller driven airplanes. The forces of P-factor‚ torque‚ slipstream‚ and gyroscopic precession all work to create a left-turning tendency during high-power‚ low-airspeed flight. P-Factor is a force from the propeller. It is also known as Asymmetrical Thrust. When you are flying an airplane at high angles of

Source: http://www.skybrary.aero/index.php/Aerofoil Effects of size of an aircraft on lift and drag are roughly the same. Lift and Drag are both aerodynamic forces hence they depend on the pressure variation around the body. Both lift and drag are directly proportional to the area of the body thus doubling the area would double lift and drag. Choosing to increase lift is down solely to the wing area
