TL;DR: In this article, the authors put the minimum fuel consumption mode into use at aero-engine afterburning condition, based on the fact that the efficiency of main combustor was higher than that of the afterburner.
Abstract: The characteristic of fuel consumption at aero-engine afterburning condition was analyzed.Based on the fact that the efficiency of main combustor is higher than that of the afterburner,this article puts minimum fuel consumption mode into use at aero-engine afterburning condition.Linear Programming was used to optimize the aero-engine performance.Digital simulations show that the specific fuel consumption was decreased by 5%~7%.The benefit of minimum fuel consumption mode at afterburning condition is much more than that of non-afterburning condition.It has great application potential in engineering.

TL;DR: In this paper, a component-level mathematical model of supersonic inlet with bleeding adjustment was developed to study of integrated performance for supersonIC inlet/engine. And the engine installed thrust was verified to be effectively enhanced 3% by the bleeding adjustment of inlet when the aircraft worked at the middle and afterburner states.
Abstract: A component-level mathematical model of supersonic inlet with bleeding adjustment was developed to study of integrated performance for supersonic inlet/engine.Meanwhile,a coupling mathematical model of supersonic inlet and turbofan engine was built via a biaxial turbofan engine component-level models and inlet component-level models to describe their collaborate relationship.The properties of outside and inside flux of the intake were calculated base on this integrated component-level model for inlet/engine.Inlet bleeding properties in supersonic working mode were also analyzed.At last,the engine installed thrust was verified to be effectively enhanced 3% by the bleeding adjustment of inlet when the aircraft worked at supersonic flight in the middle and afterburner states.

TL;DR: In this paper, an improved fire fighting arrangement has no superfluous components and it is hence compact without losing its efficiency, which can be used for fighting fires in mines and also for preventing explosions in mines.
Abstract: The fire fighting arrangement is based on a gas turbine engine. An inert gas is used for fire fighting and this can be used for fighting fires in mines and also for preventing explosions in mines. The improved fire fighting arrangement has no superfluous components and it is hence compact without losing its efficiency. The gas turbine blows air into an afterburner chamber into which is blown fuel through a distribution. This afterburner chamber is water cooled and the cooled inert combustion gases are used for fire fighting purposes. The igniter (5) chamber (8) of the afterburner chamber (3) is connected by a pipe (9) with the high pressure zone of the engine (1). The fuel distributor outlets may face the air stream for better fuel distribution.

TL;DR: In this paper, a coupled heat and power system for residential use improved by CO2 reduction is presented, which consists of a power module of solid oxide fuel cell, compressor, afterburner, recuperator, a mini gas turbine, and a circulating fluidized bed for carbon dioxide sorption.
Abstract: Today world people are aware of the negative effect of carbon dioxide on climate and life quality. Enormous researches are performed to reduce carbon dioxide production, especially in power plants. In the current research, the coupled heat and power system proposed for residential use improved by CO2 reduction is presented. The system consists of a power module of solid oxide fuel cell, compressor, afterburner, recuperator, a mini gas turbine, and a circulating fluidized bed for carbon dioxide sorption. The unburned gases are purified in a sorption system, CO2 is removed, and CO is returned to the solid oxide fuel cell. The recommended thermodynamic cycle is studied by the thermodynamics laws of energy conservation and exergy analysis while the efficiency of circulating fluidized bed is analyzed by computational fluid dynamics (CFD) techniques. As well, extensive thermal and electrochemical calculations are done to get precise consequences from parameter study. The effects of efficiency of the fluidized bed in removing CO2, air/fuel ratio, system pressure, the efficiency of mechanical parts, fuel rate on heat and power output of the system, and CO2 reduction are investigated. The efficiency of circulating fluidized bed used in solid oxide fuel cell is extracted precisely by CFD for various inlet velocity and particle diameter. Optimal conditions of the cycle are found and discussed.
