Variable geometry gas turbine engine for use in inclement weather

A variable-geometry system for a gas turbine engine, comprising:

• a sensor configured to sense a parameter;
• a control system in electronic communication with the sensor, the control system including a pre-programmed algorithm and configured to compare data from the sensor to stored parameter values and ranges to determine a particular inclement weather condition from among a plurality of different inclement weather conditions;
• a mechanism in communication with the control system;
• and
• an element in a flow path of the gas turbine engine, wherein the mechanism is configured to vary an orientation of the element in response to the pre-programmed algorithm and the control system's comparison between data from the sensor and the stored parameter values and ranges, wherein the orientation of the element is infinitely variable within a range of orientations, wherein the parameter is selected from the group consisting of total temperature, airspeed, or weight-on-wheels, wherein the control system is configured to associate a particular element orientation with a potential adverse condition derived from the comparison between data from the sensor and the stored parameter values and ranges,
• wherein the control system controls the mechanism to place the element in a first orientation in response to detecting a first inclement weather condition from the among the plurality of inclement weather conditions, and controls the mechanism to place the element in a second orientation in response to detecting a second inclement weather condition from among the plurality of inclement weather conditions different from the first inclement weather condition.
