A controller is provided, which detects operating conditions of an internal combustion engine on the basis of detection results from a group of sensors and drives an actuator that modifies an opening position of a wastegate valve on the basis of the operating conditions. When driving the wastegate valve to a fully closed opening, the controller initially drives the actuator toward a preset provisional fully closed position, and after determining on the basis of a detection result from a position sensor that an actual opening of the wastegate valve has reached the provisional fully closed opening, switches a target opening to the fully closed opening and drives the actuator accordingly.

A required opening correction amount is calculated based on a target supercharging pressure and an actual supercharging pressure, a target opening is calculated based on a required opening and the required opening correction amount, an actual operating position of a wastegate valve is determined to correspond to a fully closed position when the wastegate valve is in a fully closed condition, an actual opening of the wastegate valve is calculated based on the fully closed position and the actual operating position, an operation amount of an actuator for aligning the target opening with the actual opening is calculated based on the target opening and the actual opening, and when the target opening corresponds to the fully closed condition and the actual operating position is not decreased at or above a prescribed rate, the fully closed position is updated to the actual operating position.

An assistance device for an aircraft free-turbine turbine engine, the device including first electrical power supply for powering a winding of a starter rotary machine, referred to as a “first” winding, in order to provide first assistance in accelerating the gas generator of the engine. The device further includes a monitor for monitoring the first assistance, and a second power supply for electrically powering a second winding of the rotary machine to provide second assistance in accelerating the gas generator if the monitor observes that the first assistance is insufficient.

A gas turbine engine duct turns radially inwardly in the downstream direction. The duct includes a plurality of radially extending stator vanes. A generally circumferentially extending splitter vane is provided between two circumferentially neighbouring stator vanes. The splitter vane improves the flow near to the radially inner wall of the duct. This can allow greater design freedom in the duct geometry.

The invention is in the field of engine building technology and may be used in space technology or aviation. Liquid-propellant rockets with Laval nozzles are well known, and they have the following insufficiencies: (1) high fuel consumption rates, which lead to increased dimensions and engine weight and boosters; (2) a relatively low combustion efficiency, because the low mass of the combustion products are emitted into the environment; (3) the large length of the de Laval nozzles with increased expansion ratios increase the dimensions and the engine weight; (4) use of high temperature rocket propellants—combustion products—in the camera and de Laval nozzle. These insufficiencies suppress using liquid-propellant rockets in space technology. The goal of the invention is decreasing the influence of these insufficiencies and obtaining an engine with improved efficiency. The goal is achieved with the creation of an engine with the subsonic discharge of combustion products and the creation of a simple nozzle construction.

A gas turbine engine includes a combustion section arranged between a compressor section and a turbine section that extend in an axial direction. A fan section is arranged upstream from the compressor section. An airfoil is arranged in one of the fan section, the compressor section and the turbine section. The airfoil includes pressure and suction sides extending in a radial direction from a 0% span position at an inner flow path location to a 100% span position at an airfoil tip. The airfoil has a leading edge that is projected onto a plane from various views and the plane is perpendicular to a viewing direction which corresponds to the various views. The plane is parallel with the axial direction in a 0° view. The various views include the 0° view which projects into an axial plane in the axial direction. A 90° view projects into a tangential plane in a tangential direction normal to the axial direction and views between the 0° and 90° views. The airfoil has a maximum leading edge projection in a 20° to 40° view. The radial direction is normal to the axial and tangential directions.

A turbofan engine assembly includes a core gas turbine engine with a booster compressor having a radially outer diameter, a fan case assembly, and an outlet guide vane assembly. The outlet guide vane assembly includes a plurality of outlet guide vane segments spaced circumferentially about the core gas turbine engine. Each outlet guide vane segment of the plurality of outlet guide vane segments includes a radially inner fan hub frame flange configured to couple to the core gas turbine engine, a radially outer fan case flange configured to couple to the fan case assembly, and a plurality of outlet guide vanes extending therebetween. The radially inner diameter of the outlet guide vane assembly is smaller than the radially outer diameter of the booster compressor.

A multi-axis passenger-carrying aircraft comprises: an electrical system; a heat exchange system; a cabin; and an accommodating compartment arranged inside the cabin; wherein the electrical system is arranged inside the accommodating compartment, and wherein the heat exchange system comprises at least an air inlet communicated with the exterior of the cabin, an air outlet communicated with the accommodating compartment, and a cooler with an air inlet end communicated with the air inlet and an air outlet end communicated with the air outlet. In operation, air outside the aircraft may enter the heat exchange system via the air inlet and the cooler via the air inlet end to be cooled by the cooler. The cooled air may be discharged via the air outlet end and then enter the accommodating compartment via the air outlet, providing cool air to the accommodating compartment and dissipating heat from the electrical system.

Multi-axis passenger-carrying aircraft is provided, including: a heat exchange system; a cabin; and a passenger accommodating compartment arranged inside the cabin; wherein the electrical system is arranged inside the passenger accommodating compartment, and wherein the heat exchange system at least includes an air inlet in communication with the exterior of the cabin, an air outlet in communication with the passenger accommodating compartment, and a cooling and heating device with an air inlet end communicated with the air inlet and an air outlet end communicated with the air outlet. In operation, air outside the aircraft may enter the heat exchange system via the air inlet and the cooling and heating device via the air inlet end to be cooled or heated by the cooling and heating device. The air after heat exchange may be discharged via the air outlet end and enter the passenger accommodating compartment via the air outlet.

A charge air cooler for an internal combustion engine, includes a charge air inlet and a charge air outlet which are fluidly connected with each other via multiple charge air channels which are arranged parallel to each other and arranged parallel to each other and subjectable to a coolant flow; and at least one flow guide element arranged upstream of the charge air channels, wherein the flow guide element at least in one operating state of the internal combustion engine deflects charge air entering through the charge air inlet the direction of a condensate accumulation volume of the charge air cooler.
