Abstract: In turboprop engines, the lip of the S-shaped intake is behind the propeller rotation plane, so the complex slipstream flowfield has a strong impact on the flowfield in the S-shaped intake and affects engine performance. ...

Abstract: The phenomenon of multiple tones is a typical feature of high-lift configuration noise, and the underlying nonlinear and nonstationary features need to be revealed through time-frequency analysis. This paper introduces the ...

Abstract: To study the noise reduction effect of a variable-bend slat, both experimental and numerical investigations are carried out on a two-dimensional high-lift configuration with a stowed flap at varying angle of attack. With ...

Abstract: In this paper, the authors describe a software they have developed for wing–body parametric modeling and high-lift system design. This software has the following features: (1) it generates and modifies geometric as ...

Abstract: The present research proposed a method to reduce the Gurney-flap drag penalty with a dielectric barrier discharge (DBD) plasma actuator, which was mounted in front of the Gurney flap to generate a countercurrent wall jet. ...

Abstract: Air traffic has developed rapidly in the last decades. The noise generated from aircraft can impair the health of passengers and airport residents, so it is necessary to reduce aircraft noise and relieve the annoyance due ...

Abstract: To study the far-field aerodynamic noise of the leading-edge slat of a high-lift airfoil configuration, an experimental investigation of the BANC-II/30P30N airfoil model was carried out in the D5 areo-acoustic wind tunnel ...
