A diffuser is "a device for reducing the velocity and increasing the static pressure of a fluid passing through a system”. [1] The fluid's static pressure rise as it passes through a duct is commonly referred to as pressure recovery. In contrast, a nozzle is used to increase the discharge velocity and lower the pressure of a fluid passing ...
At least one author takes a different approach in order to avoid a need for the expression freestream static pressure. Gracey has written "The static pressure is the atmospheric pressure at the flight level of the aircraft". [15] [16] Gracey then refers to the air pressure at any point close to the aircraft as the local static pressure.
The impact digs a trench 12 to 15 feet deep and 50 to 75 feet long, and the explosion scatters small parts over three miles away which rain down for several minutes. The Orion was due to pick up eight officers and enlisted men at NAS Glenview at 1600 hrs. and fly them to Naval Air Station Moffett Field, California. [297]
The air pressure in the vicinity of the static port is conveyed by a conduit to the altimeter and the airspeed indicator. This static port and the conduit constitute the aircraft's static system. The objective of the static system is to sense the pressure of the air at the altitude at which the aircraft is flying.
The wreckage burns and the casket on board is scorched in the fire. The flight originated at NAS Miramar, California, with an intermediate stop at Albuquerque to pick up the body of a Navy pilot who was recently killed. Cause was thought to be faulty altimeter readings due to a frozen drain in the pitot static system. [295] 24 January
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 ]
An air data computer with inputs of pitot and static pressures is able to provide a Mach number and, if static temperature is known, true airspeed. [citation needed] Some authors in the field of compressible flows use the term dynamic pressure or compressible dynamic pressure instead of impact pressure. [3] [4]
The Fulton system in use The Fulton system in use from below. The Fulton surface-to-air recovery system (STARS), also known as Skyhook, is a system used by the Central Intelligence Agency (CIA), United States Air Force, and United States Navy for retrieving individuals on the ground using aircraft such as the MC-130E Combat Talon I and B-17 Flying Fortress.
