Patent number: 10829236Abstract: Herein provided are systems and methods for operating an aircraft engine during inclement weather. At least one image of a location substantially in line with a heading of the aircraft is acquired. Based on the at least one image, an inclement weather condition in the location is detected. An alert mode of the engine is triggered upon detecting the inclement weather condition. Responsive to the alert mode being triggered, at least one predetermined performance parameter of the engine is monitored.

Publication number: 20200158027Abstract: Systems and methods for mitigating flameout risk in an engine of an aircraft are provided. A humidity value is obtained from a humidity sensor associated with the engine. A flameout risk for the engine is determined based on the humidity value. The flameout risk is compared to a predetermined risk threshold. When the flameout risk is above the predetermined risk threshold, a rate of fuel flow to the engine is increased.Type: ApplicationFiled: September 16, 2019Publication date: May 21, 2020Inventors: Yen-Wen WANG, Jason HERBORTH, Tony YEE

Publication number: 20200158026Abstract: Herein provided are systems and methods for operating an engine of an aircraft. The engine is operated at a first fuel flow rate. An indication of a measured humidity level within the engine is obtained from a humidity sensor coupled to the engine. A determination is made regarding whether the measured humidity level within the engine is indicative that a flameout risk for the engine is below a predetermined risk level. Responsive to determining that the flameout risk is below the predetermined risk level, the engine is operated at a second fuel flow rate lower than the first fuel flow rate.Type: ApplicationFiled: November 19, 2018Publication date: May 21, 2020Inventors: Yen-Wen WANG, Jason HERBORTH, Tony YEE
