Numerical Study on the Effect of Vortex Generators on S-Shaped Intake in Propeller Slipstream
Publisher: ASCE
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. ...
Effect of a Variable-Bend Slat on Tones Due to the Cove’s Self-Excited Oscillation
Publisher: ASCE
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 ...
Platform for Transport Aircraft Wing–Body Parametric Modeling and High-Lift System Design
Publisher: American Society of Civil Engineers
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 ...
Gurney-Flap Drag Penalty Reduction with a DBD Plasma Actuator
Publisher: American Society of Civil Engineers
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. ...
Experimental Investigation of the Far-Field Noise Generated from the Cruise Configuration of Aircraft High-Lift Device
Publisher: ASCE
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 ...
Experimental Study of Far-Field Radiated Noise Characteristics for the Leading-Edge Slat of a 30P30N Airfoil
Publisher: ASCE
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 ...
