Systems for determining anomalous interactions based on characteristic types
Anomalous interactions with a website or other system may be detected based on the types of characteristics associated with previous anomalous interactions, independent of the values associated with those characteristics. Historical data is used to determine characteristics of interactions, each characteristic having a type and a value. For historical interactions in which a set of characteristic values are associated with a potentially anomalous interaction, the characteristic types are analyzed in subsequent interactions. If values for those characteristic types occur at a frequency greater than a threshold frequency for a set of subsequent interactions, this may indicate that the interactions are anomalous. Use of the characteristic types for this purpose, rather than historical characteristic values, enables anomalous interactions to be detected independent of the characteristic values associated with the interactions. |

The sensor is configured (i) to sense a parameter corresponding to a hydrogen fuel leak of the monitored component and (ii) to generate an output. The controller is configured (i) to receive the output of the sensor, (ii) to determine, based on the output of the sensor, if a leak has occurred in the monitored component, and (iii) to generate an output indicating a fuel system leak when the controller determines that the leak has occurred in the monitored component. The monitored component may be a component of one of a fuel tank, a power generator, and a fuel delivery assembly. |

Aircraft refuelling
A method of refuelling an aircraft comprising a gas turbine engine and a fuel tank arranged to provide fuel to the gas turbine engine comprises obtaining an amount of energy required for an intended flight profile; obtaining a calorific value of fuel available to the aircraft for refuelling; calculating the amount of the available fuel needed to provide the required energy; and refuelling the aircraft with the calculated amount of the available fuel. The calculating the amount of the available fuel needed to provide the required energy may comprise obtaining an energy content of fuel already in the fuel tank and subtracting that from the determined amount of energy required for the intended flight profile. |

Accessible debris separator for high pressure turbine outside diameter fed static components
An accessible debris separator for a gas turbine engine is provided. The accessible debris separator including a chamber formed by a entrance wall, an exit wall, an inner wall, and an outer wall; a plurality of inlet openings in the entrance wall; a plurality of outlet openings in the exit wall; and a component within the chamber, the component forcing cooling air with debris particulates entering the chamber via an inlet opening of the plurality of inlet openings to take a circuitous path thereby separating the debris particulates from the cooling air prior to the cooling air exiting the chamber via an outlet opening of the plurality of outlet openings. |

Engine nacelle anti-ice swirl system with unsteady fluid flow
An anti-ice swirl system for an aircraft engine includes a nacelle including a first nacelle section exposed to ambient environment and facing an oncoming airstream when an aircraft powered by the engine is in flight. The first nacelle section defines a circumferential D-duct. The anti-ice swirl system also includes a nozzle configured to inject into and circulate through the D-duct a controlled unsteady flow of heated fluid. The controlled unsteady flow mixes newly injected heated fluid with air inside the D-duct and mitigates icing of the first nacelle section when the aircraft is in flight. |

Aircraft propulsion system
An aircraft propulsion system includes first and second engines and first and second electrical machines coupled to the first and second engines respectively. The first electrical machine is arranged to be driven by electrical power in order to at least partially drive the first engine. The second electrical machine is arranged to be driven by the second engine to generate electrical power. An electrical network allows transmission of electrical power between the electrical machines. A controller is arranged to selectively reduce fuel flow to the first engine and provide electrical power from the second electrical machine to the first electrical machine to drive the first electrical machine, based on expected properties of contrails formed in an exhaust plume of the first engine and/or the second engine. The system allows the formation of contrails by the engines to be managed in order to mitigate climate-warming effects of the contrails. |

Method of controlling deflagration combustion process in pistonless combustor
The method is for controlling a deflagration combustion process in a pistonless combustor. The method includes scavenging combustion products of the previous cycle, introducing air into the combustor thereby initiating a flow pattern having a first flow component within the combustor. Air is introduced into the pistonless combustor in a nonparallel angle in relation to the previous air input and thereby creating a second flow component to the flow pattern for increasing speed of combustion propagation. Fuel mixed into the air is introduced for creating a fuel-air mixture flowing within the flow pattern, and igniting the fuelair mixture within the pistonless combustor thereby increasing pressure within the pistonless combustor. |

Charging system of an internal combustion engine
A charging system (20) of an internal combustion engine has a compressor (22) that compresses intake air (41) to a pressure higher than a boost pressure of the internal combustion engine. A first energy recovery turbine (25) recovers energy from an exhaust gas mass flow (45) discharged from a cylinder (12). The compressor (22) and the first energy recovery turbine (25) are disposed on a first shaft (31) and the recovered energy is transmitted directly to the compressor (22). A cooling turbine (24) expands and cools the (intake) air (41) compressed by the compressor (22) to the boost pressure required by the cylinder (12). A second energy recovery turbine (26) recovers energy from the exhaust gas mass flow (45). The second energy recovery turbine (26) and the cooling turbine (24) are on a common second shaft (32), and the second shaft (32) is coupled to at least one energy sink. |
