Impact of Sensor Geometric Dimensions and Installation Accuracy on the Results of Instantaneous SHM Based on Wave Propagation Using Wafer Active Sensors
Publisher: ASCE
Abstract: Since damage identification results can be impressed by the effects due to changes in environmental and operational conditions, developing an effective monitoring system without any prior measured baseline data, while a ...
Investigations of the Mechanical Behavior of Naturally Weathered Envelopes Based on a Long-Term Service Airship
Publisher: ASCE
Abstract: Manufactured with a multilayer functional composite fabric envelope, lighter-than-air (LTA) airships offer a cost-effective approach for payload platforms. Considering the long-term service of LTA airships and their severe ...
Adaptive Backstepping Attitude Control for Liquid-Filled Spacecraft without Angular Velocity Measurement
Publisher: ASCE
Abstract: The attitude tracking form quaternion measurements for a three-axis stabilized liquid-filled spacecraft are studied under uncertain parametric and external disturbances. The sloshing liquid inside the partially filled ...
Simultaneous Solution for Vortex and Sound of Cavity Oscillation Based on a Meshless Model
Publisher: ASCE
Abstract: A two-dimensional (2D) meshless model based on the vortex method is developed to predict the aerodynamic noise of a noncompact open cavity, which calculates the flow and sound field results simultaneously. The evolution ...
Passive Control of Vortex Shedding Noise of Circular Cylinders by Passive Air-Jet Blowing
Publisher: ASCE
Abstract: Passive air-jet blowing is an effective yet simple technique to control flow-induced noise due to vortex shedding of bluff bodies. The current study investigates the effect of the specific slot angles of passive jets in ...
Analyzing Interaction Noise from a Small Contra-Rotating Fan Enclosed with Lined and Unlined Casings
Publisher: ASCE
Abstract: The interaction noise that radiates from ducted contra-rotating (CR) fans are theoretically characterized using Green’s analytical functions for lined and unlined circular ducts containing uniform mean flow. The derived ...
Behaviors of Hypersonic Wing under Aerodynamic Heating
Publisher: ASCE
Abstract: The coupled problem of aerodynamic heating and structural heat transfer occupies a very important position in the field of aerospace engineering applications because it directly affects the accurate prediction of aerothermal ...
Aerodynamic Optimization and Noise Reduction of a Two-Stage Series Compact Fan
Publisher: ASCE
Abstract: This paper focused on the aerodynamic optimization and noise reduction of a two-stage series compact fan. The space constraints of compact fans limit the design space, which poses several challenges to aerodynamic and noise ...
Structure-Actuator Integrated Design of Piezo-Actuated Composite Plate Wing for Active Shape Control
Publisher: ASCE
Abstract: The aerodynamic performance of aircraft can be improved via shape morphing of wings actuated by piezoelectric material. An integrated design approach of piezo-actuated wings was developed while simultaneously considering ...
Performance Improvement of Trailing Edge Internal Cooling with Drop-Shaped Pin Fin Array
Publisher: ASCE
Abstract: In this paper, flow and heat transfer in a blade trailing edge cooling channel with differently shaped pin fin arrays were investigated numerically in a Reynolds number range from 10,000 to 50,000. A novel internal structure, ...
