The vane support system (VSS) causes less distortion to the rear fuselage. It is an ideal support mechanism for large aircraft wind tunnel tests. Investigating on its support interference will contribute much to the conduction and development of VSS tests. This paper presents a numerical investigation on the support interference of VSS in high speed wind tunnel using Ty154 model. CFD results are compared...
Supercritical wing is widely used in modern transport aircrafts, whose aerodynamic characteristics are rather sensitive to Reynolds number. The aerodynamic design of large airplane mainly depends on the wind tunnel, which is time consuming and costly especially for high Reynolds number test. This paper aimed to investigate the transonic Reynolds number effects of supercritical wing by numerical simulation...
This paper has investigated the cab styling of heavy-duty truck with a low air drag based on aerodynamics and aesthetics. It focuses on the relationship of air-deflector, trailer and drag through an example of air-deflector styling. The parameters, the angle of air-deflector and the height of trailer, are specifically discussed here. The gap between cab and trailer is fixed. A lower drag cab is presented...
In this paper, a systematic procedure is presented to analyze and design a stable fuzzy controller for a class of nonlinear systems. Based on the Popov-Lyapunovpsilas method, the flight model is described with the expertpsilas linguistic information involved. The linguistic information for the flight model is represented as fuzzy sets. First, we transform a fuzzy control system into a flight control...
