3.Correction and Use of the Test Date of Wind-Tunnel Model for the CK-lC Target
4.Using method of oil-flow visualization techniques and measuring Pressure distribution along airfoil chordwise and sPanwise studies have been down for sidewall boundary-layer disPlacement effect in two-dimensional wind tunnel.Three different chord models were tested in two different wind tunnel.In order to clarify the sidewall effects and study method of sidewall suction theory and sidewall interference correction method to remove effects of sidewall on model.The results of oil-flow test show that selection rational suction wary can obtain better testing results.By investigations on effects of the sidewall boundary layer suction and aPPlication of a sidewall interference correction method.
5.A damping ratio correction factor is thus defined and the relationship between structural dynamic response and damping ratio under the excitation of Davenport-style wind pressure spectrum is presented in this paper. A tuned rigidity model is designed for theoretically investigating the influence of excitation form and modal parameters on the damping ratio correction factor on the assumption that the concerned-mode damping ratios of the aeroelastic model are close to each other.
6.On the basis of a series of plane cascade wind tunnel test results the aerodynamic characteristics of axial-flow compressor intlet guide vanes with a variable trailing edge have been determined. As a result, ascertained is the necessary correction to be applied to the deviation angle of the variable trailing edge inlet guide vane when calculated as per Carter formula and also its proper application range.
