An ice detector for providing a signal indicating ice formation includes a probe protruding into an airflow. The probe extends into the airflow from a strut. The strut has one or more features which allow the probe to accrete ice at a higher temperature than would conventionally be possible. Strut

An ice detector for providing a signal indicating ice formation includes a probe protruding into an airflow. The probe extends into the airflow from a strut. The strut has one or more features which allow the probe to accrete ice at a higher temperature than would conventionally be possible. Strut features can include a notch formed therein in an upwind direction relative to the probe, and a curved surface adjacent a point of extension of the probe from the strut.

What is claimed is: 1. An ice detector for providing a signal indicating ice formation, the ice detector comprising: a probe protruding into the airflow; and a strut which the probe extends into the airflow, the strut having a notch formed therein in an upwind direction relative to the probe, wherein the notch is a cylindrical shaped cavity in a surface of the strut adjacent to a point of the probe from the strut, and wherein the notch is disposed and arranged such that it causes the airflow to increase in turbulence prior to reaching the probe, thereby increasing heat transfer from the probe to lower the actual temperature of the probe. 2. An ice detector for providing a signal indicating ice formation, the ice detector comprising: a probe protruding into an airflow; and a strut from which the probe extends into the airflow, the strut having a notch formed therein in an upwind direction relative to the probe, wherein the notch is a rectangular shaped cavity, and wherein the notch is disposed and arranged such that it causes the airflow to increase in turbulence prior to reaching the probe, thereby increasing heat transfer from the probe to lower the actual temperature of the probe. 3. An ice detector for providing a signal indicating ice formation, the ice detector comprising: a probe protruding into an airflow; a strut from which the probe extends into the airflow, the strut having a notch formed therein in an upwind direction relative to the probe, wherein the notch is disposed and in an arranged such that it causes the airflow to increase in turbulence prior to reaching the probe, thereby increasing heat transfer from the probe to lower the actual temperature of the probe; a mounting flange to which the strut is coupled, the mounting flange being configured to be fixed to a surface of an aircraft, wherein the probe extends from the strut at an inclined angle relative to a direction that is perpendicular to the mounting flange. 4. An ice detector for providing a signal indicating ice formation, the ice detector comprising: a probe protruding into an airflow,the probe having a longitudinally extending shape and a flat tip at a distal end of the probe providing an ice accreting edge; and a strut from which the probe extends into the airflow, the strut having a notch formed therein an upwind direction relative to the probe, wherein the notch is disposed and arranged such that it causes the airflow to increase in turbulence prior to reaching the probe, thereby increasing heat transfer from the probe to lower the actual temperature of the probe. 5. An ice detector for providing a signal indicating ice formation, the ice detector comprising: a probe protruding into an airflow, the probe having a longitudinally extending shape and a flat tip at a distal end of the probe providing an ice accreting edge; a strut from which the probe extends into the airflow, the strut having a curved surface adjacent a point of extension of the probe from the strut, the curve surface being positioned in an upwind direction relative to the probe to accelerate the airflow before it reaches the probe. 6. An ice detector for providing a signal indicating ice formation, the ice detector comprising: a probe protruding into an airflow; a strut from which the probe extends into the airflow, the strut having a curved surface adjacent a point of extension of the probe from the strut, the curved surface being positioned in an upwind direction relative to the probe to accelerate the airflow before it reaches the probe, wherein the strut has a notch formed therein in the upwind direction relative to the probe, wherein the notch is formed as a cylindrical shape cavity in the curved surface and is disposed and arranged such that it causes the airflow to increase in turbulence prior to reaching the probe, thereby increasing heat transfer from the probe to lower an actual temperature of the probe.
