Abstract
An air data probe includes a probe head defining a longitudinal axis between a forward tip and aft base. A port opening is defined in a side of the probe head and opening at an angle with respect to the longitudinal axis. A bulkhead within the probe head has a chamber in fluid communication with the port opening. The chamber includes a single chamber inlet having an elongated cross-sectional shape. The single elongated chamber inlet is in fluid communication with two downstream pressure conduits to provide redundancy in case one of the two pressure conduits is blocked.

An air data probe comprising:
- a probe head defining a longitudinal axis between a forward tip and aft base;
- a port opening defined in a side of the probe head and opening at an angle with respect to the longitudinal axis;
- and
- a bulkhead within the probe head having a chamber in fluid communication with the port opening, wherein the chamber includes a single chamber inlet having an elongated cross-sectional shape, and wherein the single elongated chamber inlet is in fluid communication with two downstream pressure conduits to provide redundancy in case one of the two pressure conduits is blocked.
An air data probe comprising:
- a probe head defining a longitudinal axis between a forward tip and aft base;
- a port opening defined in a side of the probe head and opening at an angle with respect to the longitudinal axis;
- and
- a bulkhead within the forward tip of the probe head having a chamber inlet in fluid communication with the port opening, wherein the chamber inlet is operatively connected to a downstream pressure conduit having an elongated cross-sectional shape to resist formation of menisci in the downstream pressure conduit.
A method of assembling heater and thermocouple coils for an air data probe, the method comprising:
- winding a heater line around a first mandrel to form a wound heater coil;
- removing the first mandrel from the wound heater coil;
- inserting a second mandrel within the wound heater coil, wherein the second mandrel includes guides for positioning the wound heater coil;
- winding a thermocouple around the second mandrel between coils of the wound heater coil to form a wound thermocouple coil;
- and
- removing the second mandrel from the wound heater coil and the would thermocouple coil.
