    摘要: Methods and systems for method for managing a hybrid-electric powerplant (HEP) comprising a thermal engine and an electric motor are described. The method comprises transmitting a thermal power command to the thermal engine to generate a thermal power output; transmitting an electric power command to the electric motor to generate an electric power output; comparing the thermal power output to the thermal power command and the electric power output to the electric power command; detecting a fault when the thermal power output deviates from the thermal power command or when the electric power output deviates from the electric power command; and accommodating the fault by modulating the thermal power command in response to a deviation in the electric power output and modulating the electric power command in response to a deviation in the thermal power output.

    摘要: An aircraft divan includes a lateral bracket connecting between front and rear legs with lateral bracket front and rear ends, a first track defined by the lateral bracket between the lateral bracket front and rear ends, an upright, having upright top and bottom ends, a second track defined by the upright between the upright top and bottom ends, a seat pan having seat pan front and rear ends, the seat pan being slidingly connected to the first track adjacent to the seat pan rear end, and a backrest having backrest top and bottom ends, the backrest being slidingly connected to the second track adjacent to the backrest top end. The seat pan rear end is pivotably connected to the backrest adjacent to the backrest bottom end such that movement of the seat pan is transmitted to the backrest so as to move together between upright and berth positions.

    摘要: There is described a method of operating a multi-engine system of an helicopter. The multi-engine system has a first turboshaft engine having a first shaft, a second turboshaft engine having a second shaft, a gearbox having a clutch system, and a range of rotation speeds defined as a placarded zone. The method generally has: rotating the first and second shafts at a flight rotation speed above the placarded zone when clutched to a load; decreasing a rotation speed of the first shaft from the flight rotation speed to a first idle rotation speed above the placarded zone; unclutching the first shaft from the load during the decreasing; and subsequently to the decreasing and the unclutching, simultaneously decreasing the rotation speeds of the first shaft and of the second shaft to a second idle rotation speed below the placarded zone, the simultaneously decreasing including clutching the first shaft to the load.

    摘要: A method and a system for synthesizing thrust from a turbofan engine are provided. The turbofan engine comprising a compressor section, a combustor, and a turbine section in serial fluid flow communication. The engine is operated and, during the operating of the turbofan engine, a pressure of fluid at an exit of the compressor section and a temperature of fluid at a location upstream of the exit of the compressor section are determined. A synthesized value of thrust from the turbofan engine is determined based on a product of at least a first factor and a second factor, the first factor being a function of the pressure and the second factor being a function of the temperature. The synthesized value of thrust from the turbofan engine is output.

    摘要: A bleed valve has a valve body enclosing a valve chamber defining a passageway between an inlet port and an outlet port. A panel is mounted into the valve body. The panel is deflectable under fluid pressure between a sealing position blocking the passageway when the bleed valve is in a close state, and a bleeding position allowing fluid flow communication between the inlet port and the outlet port when the bleed valve is an open state. A pressure control device is provided to vary a fluid pressure differential between opposite sides of the panel within the valve chamber and selectively open or close the bleed valve.

    摘要: A method and a system for providing in-flight reverse thrust for an aircraft are provided. The aircraft comprises an engine having a rotor, a compressor mechanically coupled to the rotor, and a variable geometry mechanism provided upstream of the compressor and configured to modulate an amount of compression work performed by the compressor. The method comprises operating the rotor with the variable geometry mechanism in a first position, receiving a request to increase reverse thrust for the rotor, in response to the request, adjusting the variable geometry mechanism from the first position towards a second position, the variable geometry mechanism having a greater opening angle in the second position than in the first position, and operating the rotor with the variable geometry mechanism in the second position for causing an increase in the amount of compression work performed by the compressor and an increase in reverse thrust for the rotor.

    摘要: A toaster with a steam system comprises a casing and a chassis. A slot for a bread slice is defined by the chassis. A pop-up mechanism is within the casing and supported by the chassis, the pop-up mechanism configured for supporting a bread slice received via the at least one slot, and for raising the bread slice to project partially out of the slot at an end of a toasting/steaming process. Heating element(s) in the casing are for generating toasting heat. A steam system within the casing is configured for producing steam and feeding the steam to a steam vessel in the chassis during the toasting/steaming process. A closing system has flap(s) to close the at least one slot during the toasting/steaming process, and to open the at least one slot at completion of the toasting/steaming process.

    摘要: Computer-implemented systems and methods for video content analysis are described herein. A video feed comprising at least one image captured by a camera is received. The at least one image has a plurality of regions associated with a different level of precision required for each region. An adjustable image processing algorithm is applied to each region of the at least one image to obtain for each region the different level of precision. The image processing algorithm is adjusted based of the different level of precision associated with each region. Meta data indicative of content of the video feed is generating by the image processing algorithm.
