The corresponding maximum range condition is the maximum of C L 3/2 /C D, at C L 2 = 3.C D0 /K, and so the optimum speed is 244 km/h (152 mph). The effects of the approximation C L0 = 0 are less than 5%; of course, with a finite C L0 = 0.1, the analytic and graphical methods give the same results.
The speed to fly is the optimum speed through sinking or rising air mass to achieve either the furthest glide, or fastest average cross-country speed. [1] Most speed to fly setups use units of either airspeed in kilometers per hour (km/h) and climb rate in meters per second (m/s), or airspeed in knots (kn) and climb rate in feet per minute (ft ...
In aeronautics, the rate of climb (RoC) is an aircraft's vertical speed, that is the positive or negative rate of altitude change with respect to time. [1] In most ICAO member countries, even in otherwise metric countries, this is usually expressed in feet per minute (ft/min); elsewhere, it is commonly expressed in metres per second (m/s).
For any given value of lift, the AoA varies with speed. Graphs of C L and C D vs. speed are referred to as drag curves. Speed is shown increasing from left to right. The lift/drag ratio is given by the slope from the origin to some point on the curve and so the maximum L/D ratio does not occur at the point of least drag coefficient, the ...
(For example, a pitcher's fastball speed might be 1–2 mph faster at home than on the road.) [6] PITCHf/x uses algorithms to automatically classify every pitch by type, but these algorithms are imprecise. [7] For the 2017 season, PITCHf/x was deprecated and replaced by TrackMan, a component of Major League Baseball's Statcast platform. [8] [9]
For instance a Cessna 150 at 2,500-foot (760 m) altitude and 90-mile-per-hour (140 km/h) speed needs about 60 horsepower (45 kW) to fly straight and level. The C150 is normally equipped with a 100-horsepower (75 kW) engine, so in this particular case the plane has 40 horsepower (30 kW) of extra power.
Defending Indianapolis 500 winner Marcus Ericsson looked like a double threat in Indianapolis 500 practice Thursday. Ericsson's teammate, Scott Dixon, had the second-fastest overall lap for the ...
This is a list of interface bit rates, is a measure of information transfer rates, or digital bandwidth capacity, at which digital interfaces in a computer or network can communicate over various kinds of buses and channels.
