Because both the inner and outer rings rotate, the intershaft bearings used in gas turbines do not have fixed bearing housings. As a result, the vibration of intershaft bearings cannot be measured directly. Therefore, a vibration signal can only be collec... see more

Increasing pressures in gas-turbine compressors, particularly in aeroengines where the pressure ratios can be above 50:1, require smaller compressor blades and an increasing focus on blade-clearance control. The blade clearance depends on the radial growt... see more

Were found the conditions for occurrence of dynamic auto-balancing for the case of a rotor mounted on two elastic-viscous supports, balanced by two or more passive auto-balancers of any type.A modernized energy method has been applied under assumption tha... see more

This paper reports the established conditions for static self-balancing for the case of an asymmetric rotor on two isotropic elastic supports, balanced by a passive automatic balancer of any type. In general, the plane of static imbalance does not coincid... see more

Flettner rotor is a technology that utilizes the natural wind to help the oncoming vessel. The working principle of the flettner rotor corresponds to the theory of magnus effect, in which the force arises due to the difference in pressure between the two ... see more

The article deals with the analysis of active vibration control of a rotor which is supported by journal bearings. The oil film between the journal and bushing induces the rotor instability, which causes rotor vibrations if rotational speed is greater tha... see more

Ball bearings are commonly used in high speed turbomachinery and have a critical influence on the rotordynamic behavior. Therefore, a simulation model of the bearing to predict the dynamic influence is essential. The presented model is a further step to d... see more

Due to requirements of their operating conditions, such as high speed, high flexibility and high efficiency, rotating machines are designed to obtain larger operating ranges. These operating conditions can increase the risk of fluid-induced instability. I... see more

Based on a concept of “cost reduction by large rotor and small generator”, a kind of small vertical axis wind turbine (VAWT) called a butterfly wind turbine (BWT) has been developed with rotor diameter of 7 m and five looped blades. One of the... see more
