At the newly paved Daytona International Speedway in 2011, Busch was the first to realize that the corners were smooth enough to allow a two-car draft for the complete length of the track. During test sessions on the track, when Busch was pushed by his brother Kurt 's Penske Racing teammate Brad Keselowski , they ran 15 mph faster than single cars.
Spiral slipstream, also known as propwash, prop wash, or spiraling slipstream, is a spiral-shaped slipstream formed behind a rotating propeller on an aircraft. The most noticeable effect resulting from the formation of a spiral slipstream is the tendency to yaw nose-left at low speed and full throttle (in centerline tractor aircraft with a ...
Deflected slipstream is an approach to creating an aircraft that can take off and land vertically (), or at least with a very short runway ().The basic principle is to deflect the slipstream from one or more propellers approximately 90 degrees, to create an upward thrust for vertical takeoff and a downward air cushion for landing.
Any attempt to do so by increasing angle of attack, without first increasing airspeed, will result in a stall. The actual stall speed will vary depending on the airplane's weight, altitude, configuration, and vertical and lateral acceleration. Propeller slipstream reduces the stall speed by energizing the flow over the wings. [26]: 61
where M is the pitching moment, q is the dynamic pressure, S is the wing area, and c is the length of the chord of the airfoil. is a dimensionless coefficient so consistent units must be used for M, q, S and c. Pitching moment coefficient is fundamental to the definition of aerodynamic center of an airfoil.
The full-length mirror, equipped with a sophisticated base, can capture an extensive range of health metrics, including weight, heart health, metabolic data and body composition.
A slipstream processor is an architecture designed to reduce the length of a running program by removing the non-essential instructions. It is a form of speculative computing . Non-essential instructions include such things as results that are not written to memory, or compare operations that will always return true.
Slipstream is a video by Jethro Tull, recorded during the 1980 A tour, released in 1981. It was originally released on VHS , Capacitance Electronic Disc , and laserdisc , [ 2 ] and was released as a (bootleg) DVD in Brazil (as seen in the cover on the right) in 2003.
