CONTROLLER DESIGN FOR A GAS TURBINE ENGINE

IFAC Proceedings Volumes, 1979
Abstract An aircraft gas turbine engine is modelled as a multivariable system of nonlinear dynamic equations which is subject to a number of operating restrictions. This paper considers the specific control problem of transferring the states of the engine from an operating point of low thrust to high thrust output in an optimal manner (transient mode)

Method of vibration diagnostics of aerodynamic and aeroelastic oscillations in gas turbine engine compressor

Вестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение, 2016
The paper analyzes aeroelastic (flutter) and aerodynamic (rotating stall) oscillations in gas turbine engine compressors. We review the external factors that influence these oscillations. We propose a new method of diagnosing hazardous oscillations.

General Analysis of System Efficiency in Application of Combined Power Plants for Gas-Distribution Station

Известия высших учебных заведений и энергетических объединенний СНГ: Энергетика, 2004
The paper proposes utilization of discharged heat of gas-piston engine (GPE) or contact steam-gas plants (SGP) with the purpose to heat up gas at gas-distribution stations (GDS) of combined power plants with turbine and gas-expansion units.

Experimental Quantization of Droplet Spatial Distribution in Icing Wind Tunnel with HACPI

Aerospace
The cloud spatial uniformity in the test section is crucial for icing wind tunnels in aircraft icing research and airworthiness certification. To achieve uniform supercooled large droplet (SLD) icing conditions, both the spatial variation in droplet size
