The basic technology of the pitometer log is similar to that of the pitot tube on an aircraft. Typically, the pitometer has a long tube that penetrates the ship's hull near the keel. The part of the pitometer protruding from the ship is sometimes called a pit sword or rodmeter. This tube usually has two openings: one facing the direction of ...
A pitot–static system is a system of pressure-sensitive instruments that is most often used in aviation to determine an aircraft's airspeed, Mach number, altitude, and altitude trend. A pitot–static system generally consists of a pitot tube, a static port, and the pitot–static instruments. [1]
X-15 rocket-powered research aircraft, with nose air data boom. An air data boom provides air pressure, temperature, and airflow direction data to data acquisition systems for the computation of air, ground, and water vehicle orientation, speed, altitude/depth, and related information.
Illustration of the airspeed indication and detection system on fly-by-wire aircraft. An air data module is a component of the navigation system. [1] Each unit converts pneumatic (air pressure) information from a pitot tube or a static port into numerical information which is sent on a data bus. [2]
This example, from an Airbus A380, combines a pitot tube (right) with a static port and an angle-of-attack vane (left). Air-flow is right to left. Types of pitot tubes A pitot-static tube connected to a manometer Pitot tube on Kamov Ka-26 helicopter A Formula One car during testing with frames holding many pitot tubes Location of pitot tubes on ...
The pitot tube may become blocked, because of insects, dirt or failure to remove the pitot cover. A blockage will prevent ram air from entering the system. If the pitot opening is blocked, but the drain hole is open, the system pressure will drop to ambient pressure, and the ASI pointer will drop to a zero reading. If both the opening and drain ...
Though this does not give wheel speed (as each wheel in an axle with a differential is able to turn at differing speeds, and neither is solely dependent on the driveshaft for its final speed), under typical driving conditions this is close enough to provide the speedometer signal, and was used for the rear wheel ABS systems on 1987 and newer ...
Airspeed is commonly given in knots (kn). Since 2010, the International Civil Aviation Organization (ICAO) recommends using kilometers per hour (km/h) for airspeed (and meters per second for wind speed on runways), but allows using the de facto standard of knots, and has no set date on when to stop.
