Systems and methods for thrust reverser with temperature and fluid management

A thrust reverser system for a gas turbine engine, comprising:

• a transcowl movable between a first, stowed position, a second, deployed position and a partially deployed position between the first, stowed position and the second, deployed position by at least one actuator, and in the partially deployed position the transcowl defines at least one opening;
• a source of a user input that is a command to start-up the gas turbine engine;
• at least one resistance sensor that observes a displacement of the transcowl and generates resistance sensor signals based on the observation;
• and
• a controller, having a processor, that:
• outputs one or more control signals to the at least one actuator to move the transcowl to the partially deployed position;
• receives the user input, and based on the user input, outputs one or more control signals to the at least one actuator to move the transcowl to the first, stowed position;
• receives and processes the resistance sensor signals from the at least one resistance sensor to determine whether the transcowl has encountered resistance;
• and
• based on the determination that the transcowl has encountered resistance, outputs one or more control signals to the at least one actuator to stop a movement of the transcowl and outputs the one or more control signals to move the transcowl to the partially deployed position.

A method for temperature and fluid management for a gas turbine engine having a thrust reverser, comprising:

• outputting, by a processor, one or more control signals to at least one actuator associated with a transcowl to move the transcowl to a partially deployed position, the transcowl movable between a first, stowed position, a second, deployed position and the partially deployed position between the first, stowed position and the second, deployed position by the at least one actuator, and in the partially deployed position the transcowl defines at least one opening;
• receiving, by the processor, temperature sensor signals from a temperature sensor that observes a temperature associated with the thrust reverser system;
• determining, by the processor, based on the temperature sensor signals whether a temperature associated with the transcowl exceeds a temperature threshold;
• based on the determination that the temperature is below the temperature threshold, outputting, by the processor, one or more control signals to the at least one actuator to move the transcowl from the partially deployed position to the first, stowed position;
• receiving, by the processor, resistance sensor signals from at least one resistance sensor that observes a displacement of the transcowl;
• determining, by the processor, based on the resistance sensor signals whether the transcowl has encountered resistance;
• and
• based on the determination that the transcowl has encountered resistance, outputting, by the processor, one or more control signals to the at least one actuator to stop a movement of the transcowl and outputting, by the processor, the one or more control signals to move the transcowl to the partially deployed position.
