Abstract
An air data sensor for an aircraft has a flush mounted plate at the outside surface of the aircraft and a housing for the sensor within the aircraft below the plate. A plurality of holes in the plate provide air flow to a pressure sensor in the housing. To prevent water from reaching the sensor, a trap chamber is provided below the holes. Various contorted air flow paths are disclosed. The tube to the pressure sensor may be heated.
Claims15
An air data sensor for an aircraft, comprising:
- a flush mounting plate having an exterior surface and an interior surface, said flush mounting plate defining a plurality of holes extending through said flush mounting plate;
- a housing affixed to said flush mounting plate at said interior surface;
- a pressure sensor mounted within said housing;
- a trap member mounted to said interior surface of said flush mounting plate to form a trap chamber, said trap chamber being in fluid communication with said plurality of holes in said flush mounting plate;
- and
- an air flow tube on said pressure sensor, said air flow tube extending into said trap chamber.
An air data sensor for an aircraft, comprising:
- a mounting plate defining mounting locations for mounting said mounting plate in an aircraft and defining holes through said mounting plate;
- a trap member mounted on said mounting plate and defining a trap chamber in fluid communication with said holes through said mounting plate;
- a pressure sensor in fluid communication with said trap chamber;
- an electrical connector in electrical communication with said pressure sensor.
A plurality of air data sensors for an aircraft, each of said air data sensors comprising:
- a flush mounting plate having an exterior surface and an interior surface, said flush mounting plate defining a plurality of holes extending through said flush mounting plate;
- a housing affixed to said flush mounting plate at said interior surface;
- a pressure sensor mounted within said housing;
- a trap member mounted to said interior surface of said flush mounting plate to form a trap chamber, said trap chamber being in fluid communication with said plurality of holes in said flush mounting plate;
- an air flow tube on said pressure sensor, said air flow tube extending into said trap chamber;
- wherein said flush mounting plate of each of said air data sensors being of a shape conforming to a local contour of an aircraft skin at its mounting location;
- and
- said housings being uniform between said plurality of air data sensors so that said flush mounting plates and said housings of said plurality of air data sensors are interchangeable with one another.
