Lift-induced drag, induced drag, vortex drag, or sometimes drag due to lift, in aerodynamics, is an aerodynamic drag force that occurs whenever a moving object redirects the airflow coming at it. This drag force occurs in airplanes due to wings or a lifting body redirecting air to cause lift and also in cars with airfoil wings that redirect air ...
Drag is a force that acts parallel to and in the same direction as the airflow. The drag coefficient of an automobile measures the way the automobile passes through the surrounding air. When automobile companies design a new vehicle they take into consideration the automobile drag coefficient in addition to the other performance characteristics ...
The Medium Diesel Engine (MDE) is a four-cylinder diesel engine developed by Adam Opel AG and branded "1.6 CDTI Ecotec" in most markets. Opel also adds the marketing term "Whisper Diesel" in some markets, claiming relatively low levels of noise, vibration, and harshness.
The second reference drag curve is adjusted to equal the Siacci/Mayevski retardation rate function at a projectile velocity of 2600 fps (792.5 m/s) using a .30-06 Springfield Cartridge, Ball, Caliber .30 M2 152 grains (9.8 g) rifle spitzer bullet with a slope or deceleration constant factor of 0.5 in the supersonic flight regime. In other ...
The NHRA Factory Stock Showdown (FSS) is a class of drag racing designed to showcase the Chevrolet COPO Camaro, Dodge Challenger Drag Pak, and the Ford Mustang Cobra Jet. FSS continues to be a fan favorite with growing popularity over the last ten years. The popularity of this class of racing is in large part due to the recognizable cars.
In supersonic flow regimes, wave drag is commonly separated into two components, supersonic lift-dependent wave drag and supersonic volume-dependent wave drag. The closed form solution for the minimum wave drag of a body of revolution with a fixed length was found by Sears and Haack, and is known as the Sears-Haack Distribution .
The XL1 has a curb weight of 795 kg (1,753 lb), and a drag coefficient of Cd=0.186 (a similar drag coefficient to the General Motors EV1 electric car). Frontal area is 1.5 m 2 giving a drag area of CdA=0.28 m 2. [17] Just 23.2% of the car (184 kg (406 lb)) is made out of either steel or iron; the drivetrain weighs 227 kg (500 lb).
The Aerocon Dash 1.6 wingship, a 5,000-ton ground effect vehicle concept. The Aerocon Dash-1.6 wingship was a proposed American ground-effect vehicle intended to carry large cargos and thousands of passengers over long distances at near-aircraft speeds.
