Analysis and verification of vibration isolation performance of engine mount based on low-frequency approximation method

Journal of Low Frequency Noise, Vibration and Active Control
At present, most of the turbofan engine use the articulated link mount to connect the engine to the wing. The mechanical modeling, analysis and experimental research of articulated link mount are important means in the development of engine mount.

External resistance of a gas turbine engine nacelle with boundary layer extraction

Авіаційно-космічна техніка та технологія
When creating new or modernizing existing aircraft models, a lot of attention is paid to the economic indicators of their operation. A parameter characterizing these indicators is the fuel consumption of gas turbine engines.

Study of a turbofan engine

, 2014
The aim pursued by this project is to show the design of a complete turbofan. Because this design process is very complex and large groups of engineers for their development typically need the scope thereof in a final project is very limited. However, attempts to give an overview of what this design process and show the way forward from the work done ...

Improved turbofan intake liner design and optimization

, 2013
In modern turbofan engines, fan noise is one of the principle noise sources due to increased bypass ratio of the engines. Acoustic liners in the intake and bypass sections of the engine are effective in mitigating noise generated by the fan.
