Abstract
A pitot tube includes a substantially cylindrical body portion having an interior defining a flow passage. A tip portion extends along a pitot tube axis from the body portion. The tip portion includes a high thermal conductive insert. The body portion and the tip portion including the high thermal conductive insert are integrally formed.
Claims17
A pitot tube comprising:
- a substantially cylindrical body portion having an interior defining a flow passage;
- and
- a tip portion extending along a pitot tube axis from the body portion, the tip portion including a high thermal conductive insert, wherein the body portion and the tip portion including the high thermal conductive insert are integrally formed.
A method of forming a hybrid pitot tube, comprising:
- positioning a high thermal conductive insert within a mold;
- injecting a flowable material into the mold, wherein the flowable material when cooled forms a core element, the core element extending at least partially into the high thermal conductive insert;
- forming a secondary element about the mold, wherein during formation of the secondary element, the core element is eliminated;
- forming a continuous cast body about the high thermal conductive insert, wherein the continuous cast body is formed from a first material and the high thermal conductive insert is formed from a second material;
- and
- forming the continuous cast body into a pitot tube.
