Control system for open rotor propulsion system with one or more sensors

An assembly for an aircraft, comprising:

• a propulsion system including an open propulsor rotor and a turbine engine configured to drive rotation of the open propulsor rotor about an axis;
• and
• a control system including a first sensor, a second sensor and a controller in signal communication with the first sensor and the second sensor, the first sensor configured to provide first sensor data indicative of a first environmental parameter, the second sensor mounted to the propulsion system and configured to provide second sensor data indicative of a second environmental parameter, the controller configured to control operation of the propulsion system during a first mode based on the first sensor data, and the controller configured to control the operation of the propulsion system during a second mode based on the second sensor data as a replacement for the first sensor data;
• wherein the first sensor data is within a threshold range when viewed in light of the second sensor data during the first mode;
• and
• wherein the first sensor data is at least one of lower or higher than the threshold range when viewed in light of the second sensor data during the second mode.

An assembly of an aircraft, comprising:

• a propulsion system including a housing structure, an open propulsor rotor fixed to the housing structure, an open guide vane structure fixed to the housing structure, a nose cone, and a turbine engine, the open guide vane structure axially next to the open propulsor rotor, and the turbine engine configured to drive rotation of the open propulsor rotor about an axis;
• and
• a control system including a sensor and a controller in signal communication with the sensor, the sensor configured to provide sensor data indicative of an environmental parameter external to the propulsion system, and the controller configured to monitor and/or control operation of the propulsion system using the sensor data;
• wherein the sensor is mounted with the propulsion system at a first location or a second location, the first location located on the housing structure and axially between the open propulsor rotor and the open guide vane structure, the open propulsor rotor is axially between the nose cone and the open guide vane structure, and the second location located on the nose cone.
