The invention relates to a turbofan engine having a fixed structure, a fan, a fan casing surrounding the fan, an outer nacelle arranged around the fan casing and mounted hinged on the fixed structure, and a deployment system (250) for moving the outer nacelle from a closed position to an open position, and the deployment system has a guide rail (252) fastened around the fan casing, a slider (254) movable along the guide rail (252) and having a shoe (258), an activation system for moving the slider (254) and the shoe (258) in one direction or in the other direction along the guide rail (252) alternately, and an arm (264) having one end mounted hinged on the shoe (258) and the other end mounted hinged on the outer nacelle. Such motorized deployment system makes it possible to save space and mass of the turbofan engine.

A method for converting heat to mechanical work including providing incoming heat transfer fluid (HTF) at a first temperature to a mixing chamber, providing incoming compressed gas at a second temperature to the mixing chamber, enabling the gas and the HTF to mix, producing a gas- and- HTF mix, enabling the HTF in the gas- and- HTF mix to heat the gas and isotherma l expansion of the gas in the gas- and- HTF mix, limiting volume of the gas-and-HTF mix, thereby increasing pressure of the gas and causing acceleration of a flow of the gas-and-HTF mix, causing the gas-and-HTF mix to eject through a nozzle, thereby converting the heat of the HTF to kinetic energy, and using the kinetic energy to produce mechanical work. Related apparatus and methods are also described.

The invention relates to the technical field of engines, and discloses a detonation engine which is characterized in that a duct cylinder, a gas collection cylinder and a spray pipe are sequentially connected, the gas collection cylinder is provided with a reducing section, and a sweepback blade fan driven by a second motor is arranged in the duct cylinder; an air injection cylinder is fixed in the spray pipe in a sealed mode, a penetrating wave channel is formed in the circumferential direction of the air injection cylinder, a wave tube is rotationally sleeved with the wave channel, and an arch-shaped scraper blade is fixed to the air injection cylinder and tangent to the inner wall of the wave tube. A guide cone is slidably arranged in the air injection barrel and connected with the air injection barrel through a spiral groove shifting fork mechanism, and the guide cone slides to drive the wave tube to rotate to achieve scraping and dust removal of the scraper. The end face of the air injection cylinder, the guide cone and the inner wall of the spray pipe define a combustion chamber, and the spray pipe is provided with a pressure detection assembly. The pressure of the combustion chamber can be accurately regulated and controlled, accumulated dust of the wave tube is actively removed, meanwhile, the combustion efficiency is improved, the heat-resistant service life is prolonged, pressure instability and dust accumulation pain points are solved, and the reliability of an engine is improved.
