SpaceAge Control was established in 1968 to design, develop, and manufacture pilot protection devices in support of space-based and high-performance test aircraft programs. In 1970, the company was awarded a NASA contract to produce precision, small-format position transducers for aircraft flight control testing.
The static pressure is obtained through a static port. The static port is most often a flush-mounted hole on the fuselage of an aircraft, and is located where it can access the air flow in a relatively undisturbed area. [1] Some aircraft may have a single static port, while others may have more than one.
It does this by giving an accurate measurement of the ambient atmospheric pressure (static pressure) well clear of the aircraft's fuselage. The trailing cone system trails at least one fuselage length behind the aircraft (SpaceAge Control) via a high-strength pressure tube. Static pressure is measured forward of the cone by several static ports.
The air data module is a gas pressure sensor which converts mechanical forces created by gas pressure into digital signals that can be carried to the air data reference unit. ADMs generally have a maintenance bus and communication bus, and a connector on the housing for a pressurized gas line that is connected to the pitot tube or static ports.
Static pressure probe on the nose of a Sukhoi Superjet 100 prototype Pressure measurement equipment and water tanks in Boeing 747-8I prototype Static pressure probe rig aboard Boeing 747-8I prototype; a long plastic tube, shown wound round a storage drum, is connected to a probe with static pressure orifices. The probe is trailed about two wing ...
In aircraft, the static pressure is generally measured using static ports on the side of the fuselage. The dynamic pressure measured can be used to determine the indicated airspeed of the aircraft. The diaphragm arrangement described above is typically contained within the airspeed indicator , which converts the dynamic pressure to an airspeed ...
As all information from the sensors is transmitted electrically, routing of pitot and static pressure lines through the aircraft and associated maintenance tasks is avoided. [ 5 ] In simpler aircraft and helicopters, the air data computers, generally two in number, and smaller, lighter and simpler than an ADIRU, may be called air data units ...
Air flowing into the bottle indicates that the aircraft is descending. Newer variometer designs directly measure the static pressure of the atmosphere using a pressure sensor and detect changes in altitude directly from the change in air pressure instead of by measuring air flow. These designs tend to be smaller as they do not need the air bottle.
