20220162995 | FACE SEAL ARRANGEMENT FOR REDUCED FORCE AND PRESSURE - A bearing is mounted to a static structure outwardly of the shaft, and supporting the shaft. A bearing compartment is defined by face seal arrangements on each of two axial sides of a bearing. Each face seal arrangement includes a seal seat rotating with the shaft and a non-rotating sealing ring. The seal housing is exposed to high pressure air outward of the bearing compartment. A coil spring biases the seal housing towards the seal seat, such that the sealing face is biased into contact with the seal seat by a bias force including a net fluid force acting on the seal housing and the coil spring. The sealing face is defined by a contact portion contacting the seal seat and a feed portion recessed from the seal seat. The feed portion includes a plurality of circumferentially spaced feed slots fluidly connected to at least one annular groove. | 2022-05-26 |
20220162996 | ELECTRICALLY GEARED TURBOFAN - The present disclosure provides an electrically gear turbofan that includes a fan; a first spool shaft; and an electrical gearbox including: an armature winding connected to the first spool shaft and coupled to a power source; and a magnetic receiver connected to the fan, and wherein an air gap is defined between the armature winding and the magnetic receiver. The turbines and electrical gearing enable an operator to rotate the spool shaft at a first rotational speed; power an armature winding to generate an armature magnetic field, wherein the armature magnetic field rotates at a second rotational speed; transfer rotational energy via the armature magnetic field from the spool shaft to the magnetic receiver; and rotate the fan at a third rotational speed. In some aspects, the third rotational speed is controlled via a direction and a magnitude of the second rotational speed relative to the first rotational speed. | 2022-05-26 |
20220162997 | METHOD FOR REGULATING THE TEMPERATURE OF THE EXHAUST GASES OF A TURBOMACHINE - A method for regulating the temperature of the exhaust gases of a turbomachine, the method including regulation of the injection of fuel into a combustion chamber of the turbomachine so that the turbomachine generates a target thrust; regulation of the injection of mechanical power by an electric motor onto a shaft driven in rotation by a turbine, the electric motor being activated when a clearance between a casing and the blades of the turbine exceeds a threshold value. | 2022-05-26 |
20220162998 | SYSTEM AND METHOD FOR VALIDATING VALIDITY OF SENSOR USING CONTROL LIMIT - The present disclosure relates to a system and a method for validating the validity of a sensor, in particular, validating the validity of a sensor using a control limit. The present disclosure provides a method for validating the validity of a sensor using a control limit, including inferring a posterior distribution of a parameter in a Bayesian technique using a prior distribution of the parameter of sensor data and historical data of the sensor, setting a target credible interval for the posterior distribution of the parameter and setting a control line of the sensor data using the set credible interval, and validating the validity of the sensor by monitoring whether the actual measurement data of the sensor deviates from the control line. | 2022-05-26 |
20220162999 | CRACKING AND SEPARATION OF AMMONIA FUEL - A gas turbine engine includes a cracking device that is configured to decompose an ammonia flow into a flow that contains more hydrogen (H2) than ammonia (NH3), a first separation device that separates hydrogen downstream of the cracking device, wherein residual ammonia and nitrogen are exhausted as a residual flow. The separated flow contains more hydrogen than ammonia, and nitrogen is exhausted separately as a hydrogen flow. A combustor is configured to receive and combust the hydrogen flow from the separation device to generate a gas flow. A compressor section is configured to supply compressed air to the combustor. A turbine section is in flow communication with the gas flow produced by the combustor and is mechanically coupled to drive the compressor section. | 2022-05-26 |
