AGARD-C standard wind tunnel model on a sting fixture (CAD model) AGARD-C wind tunnel model on a bent sting (CAD model) A hypothetical wind tunnel model on a Z-sting (CAD model) In experimental fluid mechanics, a sting is a test fixture on which models are mounted for testing, e.g. in a wind tunnel. A sting is usually a long shaft attaching to ...
The Wind Corrected Munitions Dispenser or WCMD system is a US tail kit produced by Lockheed Martin for use with the Tactical Munitions Dispenser family of cluster bombs to convert them to precision-guided munitions.
The passive yaw systems utilize the wind force in order to adjust the orientation of the wind turbine rotor into the wind. In their simplest form these system comprise a simple roller bearing connection between the tower and the nacelle and a tail fin mounted on the nacelle and designed in such a way that it turns the wind turbine rotor into ...
The increased low wind capabilities of optimized, modern devices enable downwind steering down to 1.3 m/s apparent wind and 1.5 kn of boat speed [8] [9] – properties that make an electronic steering device nearly redundant and enable crossing the doldrums under wind vane self-steering. An increasing number of long distance regatta sailors are ...
The main changes to the Nuna 4 from its predecessor the Nuna 3 are a steering wheel instead of levers, an upright seat instead of the driver lying down and a smaller solar panel of 6 m 2 compared to the previous 9 m 2. These changes were necessitated by changes in the rules prompted by alleged safety concerns and attempts to make the car more ...
The airborne wind shear detection and alert system, fitted in an aircraft, detects and alerts the pilot both visually and aurally of a wind shear condition. A reactive wind shear detection system is activated by the aircraft flying into an area with a wind shear condition of sufficient force to pose a hazard to the aircraft.
Recent wind shear alerts may also feature in radio broadcasts by the automated terminal information system (ATIS). LLWAS wind shear and microburst alerts assist pilots during busy times on final approach and on departure, often when heavy traffic, low ceilings, obstructions to vision, and moderate to heavy precipitation add to the difficulty in ...
