With the vibration tests, deformations can be recorded with millimetre accuracy and material stresses analysed Five hundred sensors measure the structural dynamics directly on the rotor blade Funded ...

Individual control of rotor blades reduces noise, vibration and fuel consumption. Functional tests for five-blade rotors in wind tunnel successfully completed. Focus: Aeronautics, Aircraft noise Under ...

Improving helicopter performance while reducing noise and vibration is the aim of the international Smart Twisting Active Rotor (STAR) project. Led by the German Aerospace Center (Deutsches Zentrum ...

Eurocopter test flew an EC145 helicopter equipped with a five-blade bearingless rotor system from its Donauwörth plant in Germany late last month. The European helicopter manufacturer has designed the ...

Rotor dynamics and vibration analysis encompass the study of the behaviour of rotating machinery subjected to various excitations and uncertainties. This field, which lies at the intersection of ...

Airbus Helicopters is to institute a series of modifications on the H145 that will increase the payload of the light-twin by 150kg (330lb). Key to the upgrade is a new bearingless five-blade main ...

Steam turbine rotors are susceptible to bending during some operational evolutions, which can lead to excessive vibration and ultimately failure. Rotor bending that results in premature failure of ...

Steam turbine blades are critical components in power generation, and their failure can have profound economic and safety implications. Recent studies have underscored the importance of understanding ...
