Abstract
An air data probe (10) such as a pitot probe, pitot-static probe, or total air temperature probe incorporates heaters (42) within the wall (30) of the device. The heater (42) extends from the base (12) of the probe (10) to the tip (18) of the probe (10). In a preferred embodiment, the heater (42) is a wire heater that extends in the wall (30) of the probe (10) from the base (12) to the tip (18), and surrounds a sampling chamber (24) in the probe (10) in a spiral pattern.
Claims19
An air data probe having an outer surface and comprising a base for attachment to a structure, a tip for extending into an air stream, and a body extending from the base to the tip and having a sampling chamber therewithin that extends from the base to the tip, wherein the outer boundary of the sampling chamber is defined by a chamber outer surface, and the chamber outer surface and the body outer surface define a wall therebetween having a uniform composition cast metal microstructure, wherein means for heating the probe are disposed in the wall and extend from the base to the tip.
A heated air data probe for attachment to an air vehicle, the probe having an outer surface and comprising a base for attachment to the air vehicle, a tip extending into an air stream, and a body extending from the base to the tip, wherein the tip includes a pitot port and the body includes a pitot chamber that extends in the probe body and provides for fluid communication between the port and a pitot pressure transducer, wherein the outer boundary of the pitot chamber is defined by a chamber outer surface, and the chamber outer surface and the probe outer surface define a solid wall therebetween, and wherein the probe includes means for heating the probe body that extend in the probe wall from the probe tip to the probe base.
A heated air data probe for attachment to an air vehicle, comprised of a base for attachment to the vehicle, a tip extending into an air stream, a body having an outer surface and extending from the base to the tip, and a head attached to the tip for sampling the air stream, wherein the head includes an air sampling passageway in communication with a fluid carrying conduit that extends from the tip to an air data transducer, wherein the probe body includes a chamber through which the conduit passes, and the surface of the chamber and the surface of the body define a wall therebetween, and wherein the probe includes a first heater for heating the probe body, the heater extending in the wall of the probe from the base to the tip, and a second heater for heating the head.
