Preliminary Aerodynamic Design Strategy for Prop-Rotors Based on Multifidelity Methods
Publisher: ASCE
Abstract: A design strategy to provide suitable baseline prop-rotors for sophisticated applications is presented. Unlike those approaches aimed at improving the aerodynamic performance of an already refined blade by high-fidelity ...
A FENN-TL Approach for Reliability Analysis of a Primary Ice Detection System
Publisher: ASCE
Abstract: Solving the reliability problem of primary ice detection systems is of great significance to support the design of anti-icing systems. In this paper, an efficient method employing a feature-enhanced neural network ...
Multiobjective Optimization of Double-Wall Cooling Structure of Integrated Strut Flame Stabilizer and Sensitivity Analysis of Parameters
Publisher: ASCE
Abstract: The thermal environment behind the integrated strut of the afterburner is very harsh. A double-wall structure is set at the integrated strut flame stabilizer for cooling. The multiobjective optimization of the double-wall ...
Dynamic Characteristics of Labyrinth Seal and Rotor Stability Considering Swirl Brakes
Publisher: ASCE
Abstract: The numerical solution model of the labyrinth seal considering the multiple frequencies elliptical whirling of the rotor and swirl brake was established by the computational fluid dynamics (CFD) technique. Then, the dynamic ...
Sliding Mode Controller Based on Genetic Algorithm and Simulated Annealing for Assured Crew Reentry Vehicle
Publisher: ASCE
Abstract: A sliding mode (SM) re-entry control system is proposed for an assured crew re-entry vehicle (ACRV). The vehicle has a low lift/drag ratio (0.3). The trajectory controller drives the ACRV in a predefined track. The reference ...
Rotational Speed Optimization of Coaxial Compound Helicopter and Turboshaft Engine System
Publisher: ASCE
Abstract: In order to enhance the overall performance and operational efficiency of the integrated coaxial compound helicopter and turboshaft engine system, a preliminary study on the optimal rotational speeds was implemented based ...
Lift and Tip Vortices Generated by Tapered Backward-Swept and Forward-Swept Wings under Stationary Ground Proximity
Publisher: ASCE
Abstract: An experimental investigation of the aerodynamics and near-field tip-vortex flow field behind tapered backward- and forward-swept wings with a stationary ground effect was conducted at Reynolds number (Re)=1.81×105. The ...
A New Circular Section Control for Streamwise Profiles in Aeroengine Nacelle Cowl Design and Optimization
Publisher: ASCE
Abstract: Nacelle cowl design is dedicated to generating a three-dimensional surface with optimal drag performance. Most previous approaches focused primarily on the design method driven by streamwise profiles, which introduced no ...
