Abstract: An aircraft jet engine comprising a nozzle to eject a gas stream, and a system for reducing the noise generated by the ejection of the gas stream. This system comprises several ducts which each are connected upstream to a recess divided into several chambers and open, downstream, at the outlet of nozzle. In this way, each duct ejects a fluid jet deriving from the recess and which interacts with the gas stream of the engine. The system also comprises a pulsation means for the fluid jet which brings about its ejection at the nozzle outlet and/or modulates its speed by varying the volume contained in the recess.

Abstract: The invention relates to an aircraft jet engine comprising a nozzle (2) intended to eject a gas stream, and a system for reducing the noise (3) generated by the ejection of the gas stream. This system comprises several ducts (11a) which each, on the one hand, are connected upstream to a recess divided into several chambers and, on the other hand, open, downstream, at the outlet of nozzle (2). In this way, each duct ejects a fluid jet deriving from the recess and which interacts with the gas stream of the engine. The system also comprises a pulsation means (12) for the fluid jet which brings about its ejection at the nozzle outlet and/or modulates its speed by varying the volume contained in the recess. The system is configured in particular for balancing static pressures between the chambers.

Abstract: System and method for debugging a program. A graphical user interface (GUI) displays source code for the program in a first GUI element, and first user input is received to the first GUI element indicating an expression, e.g., including one or more one or more variables, constants, macros, and/or operators, in the source code. A value of the expression is displayed in a tooltip in response to the first user input. Second user input is received to the tooltip modifying the value, thereby specifying a new value, and the expression in the program is set to the new value. The program continues execution in accordance with the new value of the expression. The tooltip includes a first portion, e.g., context sensitive control, displaying the value and to receive the second user input modifying the value, and a second portion, e.g., text indicator, displaying non-editable information related to the expression.
