One or more of the batteries may be jettisoned during flight in order to reduce weight and as they are depleted. In some implementations, a depleted battery may remain electrically connected with the turbopump(s) while a new battery is electrically connected with the turbopump(s). The depleted battery may then be electrically disconnected from the turbopump and jettisoned.
US11408372B2	Gas turbine engine front architecture A turbine engine is disclosed that includes a fan case surrounding a fan rotatable about an axis. A core is supported relative to the fan case by support structure arranged downstream from the fan. The core includes a core housing having an inlet case arranged to receive airflow from the fan. A compressor case is arranged axially adjacent to the inlet case and surrounds a compressor stage having a rotor blade with a blade trailing edge. The support structure includes a support structure leading edge facing the fan and a support structure trailing edge on a side opposite the support structure leading edge. The support structure trailing edge is arranged axially forward of the blade trailing edge. In one example, a forward attachment extends from the support structure to the inlet case.
US11408368B2	Reconfigurable exhaust nozzle for a gas turbine engine A propulsion unit includes a gas turbine engine arranged along an axis and an exhaust system coupled to the gas turbine engine. The gas turbine engine includes an engine core configured to discharge a core flow and a fan configured to be driven by the engine core to discharge a bypass flow. The exhaust system receives the mixed bypass and core flows from the gas turbine engine.
US11408363B2	Control method, device and storage medium for engine operation A control method, a control device, an electronic device and a storage medium for engine operation are provided. The method includes: obtaining a rotational speed and a temperature of an engine at a current time and determining a reference value of the control parameter of the engine based on the rotational speed and the temperature; detecting a composite operating state of the engine at the current time and determining an offset of the control parameter corresponding to each operating state in the composite operating state; adding the reference value of the control parameter and the offset of the control parameter corresponding to each operating state in the composite operating state to obtain a final value of the control parameter; and controlling the engine at the current time according to the final value of the control parameter.
US11408361B2	Charge air cooler drain system An internal combustion engine having an intake manifold, a compressor in fluid communication with the intake manifold, a charge air cooler in fluid communication with and between the compressor and the intake manifold, a throttle controlling fluid communication between the air charge cooler and the intake manifold, and a condensate collection reservoir that collects condensate from the air charge cooler and is in fluid communication with a suction port of a Venturi device in a bypass loop around the throttle. A motive inlet of the Venturi device is in fluid communication upstream of the throttle and a discharge outlet is in fluid communication downstream of the throttle, and under operating conditions that provide an adequate pressure drop across the Venturi device, the suction port draws condensate from the condensate collection reservoir and introduces the condensate into the intake manifold as a mist.
US11408349B2	Active flow control transpirational flow acoustically lined guide vane A vane for use in a gas turbine engine includes an airfoil having a suction side and a pressure side, and a transpirational flow acoustic liner disposed in the airfoil. The liner includes a face sheet defining a portion of an outer surface of the airfoil and having a plurality of first apertures, a segmented member coupled to the face sheet, and a backing sheet coupled to the segmented member the segmented member such that the segmented member is positioned between the face sheet and the backing sheet. The segmented member includes a plurality of chambers in fluid communication with the outer surface via the plurality of first apertures. The backing sheet has a plurality of second apertures.
US11408347B2	Fuel systems A fuel system can include a total flow line configured to receive a total flow and a primary flow line connected to the total flow line. The primary flow line can be in fluid communication with one or more primary fuel nozzles of a nozzle assembly. The fuel system can include a secondary flow line connected to the total flow line in parallel with the primary flow line, the secondary flow line in fluid communication with a plurality of secondary flow nozzles of the nozzle assembly. The fuel system can include a flow split system configured to control a flow split between a primary flow of the primary flow line and a secondary flow of the secondary flow line.
