Proc. ASME. GT2020, Volume 10B: Structures and Dynamics, V10BT27A028, September 21–25, 2020
Publisher: American Society of Mechanical Engineers
Paper No: GT2020-16260
... the influence of geometry deviations, the calculations of the model with nominal dimensions and the model with the most unfavorable geometric dimensions (worst cases) have been carried out. The obtained influence coefficients for geometric and weight tolerances are then used for probabilistic modeling...

Proc. ASME. GT2020, Volume 1: Aircraft Engine; Fans and Blowers, V001T01A034, September 21–25, 2020
Publisher: American Society of Mechanical Engineers
Paper No: GT2020-16039
..., the aerodynamic and MI characteristics of the blades may deteriorate due to geometric deviations from the nominal airfoil at manufacture. Thus, to increase the robustness of the fan blades, it is necessary to solve the problem of creation of the fan blade models and the arrangement of the blades in the wheel...

Publisher: American Society of Mechanical Engineers
Paper No: GT2010-23149
.... The main aim was to evaluate the heat transfer impact on the compressor efficiency. In addition to this a simplified 1-D model was then developed and validated with experimental measurements. Based on the data generated by the model, a correlation for the compressor non-adiabatic efficiency is presented...

Paper No: GT2009-59618
...%. A simplified 1-dimensional heat transfer model was also developed and compared with experimental measurements. The algorithms calculate the heat transferred through the turbocharger, from the hot end to the cold end by means of lump masses. The compressor performance deterioration from the adiabatic map...
