Abstract: The aero-engine casing is a key component for carrying loads. With the purpose of improving the thrust-weight ratio of the aero-engine, the casing is required to be designed to be as thin as possible. Therefore, the vibration ...

Abstract: In this paper, three-dimensional multiblade row unsteady Navier–Stokes simulations at a hot streak temperature ratio of 2.0 have been performed to reveal the effects of rotor tip clearance on ...

Abstract: A zero inlet swirl turbine rotor (ZISTR) works with axial inlet gas flow directly exhausted from a combustion chamber without any upstream vanes. The suction side trailing edge shock of the ZISTR generates a significant ...

Abstract: To estimate the thermal properties from transient data, a model is needed to produce numerical values with sufficient precision. Iterative regression or other estimation procedures must be applied to evaluate the model ...

Abstract: In order to solve the problem of rotor-rotor inter-shaft labyrinth seal rubbing fault during the test run of a counter-rotating dual-rotor aero-engine, based on the fast Fourier transform, the vibration time-domain signals ...

Abstract: Abstract. Comparative analysis is conducted to clarify the influence mechanisms of rotor–rotor interactions on the blade loading of vaneless counter-rotating compressors at different matching speeds. Results reveal that ...

Abstract: Abstract. Vaneless counter-rotating configurations are known to improve aero-engine thrust-to-weight ratios; however, the sealing behavior of labyrinth seals under counter-rotating conditions has not been thoroughly ...
