Wind Tee: A tee-shaped free rotating device that indicates wind direction.
Wind Tunnel: A chamber of tunnel shape in which experiments are made to collect aerodynamic data. A steady stream of air is blown through the tunnel by a large fan at a predetermined speed.
cross wind techniques
Because of restricted or limited areas of operation, it is not always possible to take off or land the seaplane directly into the wind. Such restricted areas may be canals or narrow rivers.
Wind tunnel tests for the aircraft design has been completed. The design was noted to be "workable and robust." [7]

Blowdown Wind Tunnel
An open-circuit wind tunnel in which gas stored under pressure is allowed to expand through a test section to provide a stream of gas or air to test a model.

Note that the word velocity always refers to a vector, while the word speed always refers to the corresponding scalar magnitude; see section 19.1.4.
Head wind - A wind that is blowing in the opposite direction the aircraft is flying, thereby impeding its forward airspeed.
-Of course if one has to fly teeth of a wind and can choose one's own a] it is desirable to fly low where the head wind its smaller velocity, and when flying with the lowing wind to rise to considerable altitudes.
(That is why one cannot hose the dust off of a car and why there is dust on the backside of the fans in a wind tunnel.) Just above the surface the fluid has some small velocity.
Another basic statement: It's not the wind that should concern you (within limits, of course), it's, first, the gust spread and then the variable direction, that should get your attention.
Because North American lacked a suitable wind tunnel, it was forced to use Curtiss' facility.
When used concerning wind conditions the word means the component of wind that blows 90 degrees to the direction of the runway. Generally crosswinds make landings more difficult than if the wind were blowing parallel to the direction of the runway.
CL and CD are not expressed by any physical unit, they are rather absolute numbers obtained from either wind tunnel tests or derived mathematically.
Initially both CL and CD increase as the angle of attack increases.
With the help of their wind tunnel, they were able to carry out research that enabled them to develop a propeller that converted 66 per cent of the engine's power into forward thrust.
What made Wenham's findings so important is that he had measured them in his new invention, the wind tunnel, which he built in 1871 with John Browning.
CROSSWIND A crosswind is any wind that is blowing perpendicular to a line of travel, or perpendicular to a direction.
If you are an inexperienced pilot, you might not want to attempt tail into the wind takeoffs and landings, since they are slightly more difficult to perform.
When there is no wind the magnetic heading will remain constant, but as there is almost always some wind it will push you off course and you must correct the magnetic heading to keep the aircraft nose pointed at the NDB.
Prevailing Wind - The direction of the wind that blows most frequently across a particular region.
Profile - The position of the aircraft during an approach or departure in terms of altitude above the runway and distance from the runway end.
Instruments onboard the aircraft display this airspeed, which equals not only the speed of the plane relative to the ground, but also the speed of any wind that may be blowing toward the aircraft (aircraft normally take off headed into the wind).
I want to mention as well that "Gougeon Brothers" with the help of NASA have done multiple studies on wood composite for wind turbines ! If a composite part is correct build it has better physical properties than most plastics / metal's.
They created a small wind tunnel in which they could measure the lift and drag of a wide variety of airfoils and airfoil combinations, a pursuit that interested them so intensely that they often worked at it around the clock.
KITE - Usually tethered heavier-than-air craft, sustained in the air by its airfoil surfaces being inclined to the wind to generate lift.
LANDING WEIGHT - Normal maximum weight at which an aircraft is permitted to land.
This was not the case in scientific circles some 120 years ago, but now is common knowledge, and justifies the wind tunnel tests where true air flows over an airfoil and from which we can predict characteristics of an airplane moving through still ...
Weather, measured ceiling two thousand overcast, visibility three, haze, smoke, temperature seven one, dew point five seven, wind two five zero at five, altimeter two niner niner six.
The only exceptions are those degrees, such as aeronautical engineering, computer science, and avionics technology, that require complex, comprehensive training facilities and equipment, such as wind tunnels or the airway science lab.
