Numerical and Experimental Investigations on Windage Heating Effect of Labyrinth Seals
Publisher: ASCE
Abstract: The heat load caused by windage heating effect of labyrinth seals seriously influences the sealing of shaft air flow. To reveal the windage heating effect of labyrinth seals to reasonably design an aeroengine rotor, this ...
Single-Layer Deployable Truss Structure Driven by Elastic Components
Publisher: American Society of Civil Engineers
Abstract: This study proposes a concept of a single-layer deployable truss structure driven by elastic components which is applicable to small satellites. The structure is self-deployable from its stowed state to a planar regular ...
Solutions to Planar Aircraft Perching Problem Utilizing Sideslip Maneuvering
Publisher: ASCE
Abstract: This paper presents a dynamic analysis, optimization framework, and control formulation of a sideslip maneuvering technique that can be implemented in a two-dimensional (2D) planar perching problem. This aggressive maneuver ...
Structural Damage Detection and Localization with Unknown Postdamage Feature Distribution Using Sequential Change-Point Detection Method
Publisher: American Society of Civil Engineers
Abstract: The high structural deficient rate poses serious risks to the operation of many bridges and buildings. To prevent critical damage and structural collapse, a quick structural health diagnosis tool is needed during normal ...
Influence of Unsteady and Kinematic Parameters on Aerodynamic Characteristics of a Pitching Airfoil
Publisher: American Society of Civil Engineers
Abstract: Most unmanned aerial vehicles which fly with moving wings or encounter gusts at low Reynolds number conditions make pitching oscillation motions. The aerodynamic forces and flow field around the wings vary dramatically ...
Dynamic Mode Decomposition Analysis of the Unsteady Flow in a Centrifugal Compressor Volute
Publisher: American Society of Civil Engineers
Abstract: The volute has a significant effect on the unsteady characteristics of the centrifugal compressor. The flow in the centrifugal compressor volute is unsteady and complex. In this paper, the dynamic mode decomposition (DMD) ...
Tabletop Testbed for Attitude Determination and Control of Nanosatellites
Publisher: American Society of Civil Engineers
Abstract: To simulate the conditions of the space environment at ground, the Laboratory of Application and Innovation in Aerospace Science (LAICA) of the University of Brasília (UnB) is developing a dedicated testbed to reproducing ...
Effect of Slot Area Ratio and Slot Angle on Swirl Cooling in a Gas Turbine Blade Leading Edge
Publisher: ASCE
Abstract: This paper numerically simulated a swirl cooling system to study the influences of the slot area ratio and slot angle on the flow field and heat transfer performance. Numerical simulations were performed for different ...
Physically Based Constitutive Model for Viscoplastic Deformation of Inconel718 at High Strain Rates and Temperatures
Publisher: ASCE
Abstract: In the cutting process of nickel-based superalloys, because of the high strain rate and cutting temperature, the cutting deformation is complex and there exist hardening and softening phenomena. Therefore, the present study ...
Experimental Evaluation of a Low-Cost RFID-Based Sensor to Crack Propagation
Publisher: American Society of Civil Engineers
Abstract: A passive radio frequency identification (RFID)-based crack sensor was developed and its sensitivity to crack propagation on metallic plates has been experimentally validated. A crack propagation test method was designed ...
