Abstract: This paper aims to develop an applicable nonlinear control technique for aeroengines. An approximate nonlinear model is presented and a rational identification procedure is given. Exact input-output ...

Abstract: The multiobjective regulating and protecting control method presented here will enable improved control of multiloop switching control of an aeroengine. The approach is based on switching control ...

Abstract: It is noticed in a few steam turbines that there are a pad temperature rise of more than 10°C and a radial journal movement of more than 50 μm in the bearings adjacent to control ...

Abstract: The working environment of hot components is the most adverse of all gas turbine components. Malfunction of hot components is often followed by catastrophic consequences. Early fault detection plays a significant role in ...

Abstract: A nonlinear dynamic model is developed for a rotor-bearing system with radial steam force due to partial admission, taking into account the prediction of subsynchronous instability of a steam ...

Abstract: A novel method for measurement selections of gas path diagnostics has been developed. This method is based on the singular value decomposition of the observability matrix of linear systems, ...

Abstract: The ignition characteristics of a flush wall, liquid-kerosene-fueled scramjet combustor are tested in a directly connected ground test rig. The total temperature and Mach number of the vitiated airflow at the exit of the ...
