  • Modeling of longitudinal unsteady aerodynamics at high angle-of-attack based on support vector machines

    Accurately modeling nonlinear and unsteady aerodynamics at high attitude flight plays an important role in design of future high performance fighters. In the meanwhile, it also can improve the prediction of high angle of attack dynamics of normal aircraft configurations. Support vector machines (SVMs), known as a novel type of learning machines based on statistical learning theory and structural risk minimization (SRM) principle, can be used for handle regression problems. By denoting a set of nonlinear transformations from the complex input space to a high-dimensional feature space, SVMs can approximate the regression function by a linear regression in the feature space. Such implementation is so simple that it can be analyzed mathematically. By employing SVMs, the present work models the unsteady pitching oscillation aerodynamic data of a 1/10 scaled aircraft model. Here, the input data are established from the wind tunnel experiments at different frequencies and amplitudes. To make comparison, the artificial neural networks (ANNs) technique is also used. It turned out that SVMs can overcome the ANNs's inherent drawback of slow training convergence speed. Consequently, SVMs demonstrate high potentials for dealing with the chosen modeling of unsteady aerodynamics.

  • Aerodynamics properties and design method of high efficiency-light propeller of stratospheric airships

    The low density of stratospheric air and small flight speed of airship bring certain difficulty to the aerodynamic design of stratosphere airship propeller. This paper firstly analyzes characteristics of flow around the propeller for an airship in atmospheric environment and the influence of the propeller outlet flow angle to sectional efficiency, then discusses the principle and the method of choice in geometry parameter of the propeller with the equal Re number and the equal stress principle. To specially avoid the appearance of laminar separation bubble (lower the efficiency), we adopt the airfoil with the low Reynolds Number and high lift in the design and present a three-blade propeller of composite materials with the variable-speed and fixed-pitch according to the design criteria of the airship propeller. The detail specification of the propeller is: the diameter D=6500 mm, propeller actual factor 62.3, maximum width 516 mm, and propeller pith angle 32.80. The paper also evaluates the aerodynamics performance in detail with the strip theory.

  • Wall Temperature Effects on Hypersonic Aerodynamics of the Mars Entry Capsule

    The chemical non-equilibrium method is implemented to investigate wall temperature effects on the hypersonic aerodynamics of the Mars entry capsule named Mars Science Laboratory (MSL). Two isothermal walls (1000 and 2000K) and a radiative-equilibrium wall temperature are used to take account of the temperature effects, respectively. The numerical results show that, the wall temperature has no significant effect on the pressure of the forebody, while influences the pressure of the afterbody remarkably, especially at the separation area. The shear stress of the forebody increases with the wall temperature increased, and the wall temperature affects the shear stress of the afterbody obviously. The wall temperature has no significant effects on the aerodynamics of the forebody. At different wall temperatures, the maximum discrepancy of the forebody's axial force coefficient, normal force coefficient and pitch moment coefficient is merely 0.05%, 1.0% and 1.2%, respectively. The wall temperature impacts the aerodynamics of the afterbody significantly. At different wall temperatures, the maximum discrepancy of axial force coefficient, normal force coefficient and pitch moment coefficient of the afterbody is 55.7%, 26.4% and 61.5%, respectively.

  • Analysis of effects of rebounds and aerodynamics for trajectory of table tennis ball

    In this paper, we firstly analyze the effects of the rebounds and aerodynamics for trajectory of a table tennis ball. We firstly analyze the effect of the aerodynamics with a criterion of evaluation, where the half area of the table is considered as 9 divided areas. Furthermore, the drag and lift coefficients are identified by assuming that the rotational velocity is invalid during the ball flying. With the identified coefficients, the modeling errors of the table and racket are secondly verified by the criterion mentioned previously. Some conclusions are finally shown.

  • Simulation analysis and validation on aerodynamics of tunnels on high speed railways

    With the increase of train speed, the issue of tunnel aerodynamics becomes more important. A simulation platform based on CFX is established to fulfill simulation calculation of tunnel aerodynamics for 300km/h high speed railways, with emphasis laid on studying the changing rules of compression wave and pressure transient on tunnel wall while the train enters tunnel as well as micro-pressure wave at tunnel portal with speed increase. The simulation results are then compared with actual measuring result. It is shown that the simulation result is basically consistent with laboratory measurement thus the finite element simulation could be applied in practice; amplitude of the initial compression wave will slightly decrease with the increase of tunnel length and the amplitude bandwidth will gradually increase. When the train speed is no more than 300km/h, the micro-pressure is basically proportional to cube of speed and when the train speed is more than 300km/h, the micro- pressure will see drastic increase and it is proportional to 6.5th power of speed.

  • Simulation of the autobody aerodynamics for car interior noise control

    For the analysis of car interior noise at high speed, the influence of autobody aerodynamics should be taken into account, besides the vibration and acoustic radiation of powertrain, the random excitation from road and the vibration inputs of tires, and so on. A model of CFD was built. And the most turbulent area of autobody surfaces was located. The spectrum of average aerodynamic pressure of monitoring points on front door window was also obtained by unsteady calculation. So, the more accurate analysis of car interior noise can be processed due to loading the power inputs listed above to the simulation model, which is looked as the foundation of further optimization of car interior noise control.

  • Study the effect of rear spoiler on car aerodynamics characteristics

    Taking CFD software as the platform and the car as the research object, the air's resistance coefficients and speed are solved by using RNG k-ε equations and dynamic mesh method. The finite volume method is used to discrete the governing equations, the second-order up wind difference scheme is adopted for the convection term and the centric difference scheme for the dissipation term. The discretion of time is carried out by a full-implicit time integral scheme. PISO algorithm is adopted to the transient numerical simulation. The influence law of automobile air flow in the rear and its turbulence on car aerodynamics characteristics with or without a spoiler is achieved. The simulation results are consistent with the test ones. It is proved that the numerical simulation of automobile air flow with dynamic grid in CFD software is feasible, and which provides the references for the development of automotive products with spoiler.

  • Mach number prediction models based on Ensemble Neural Networks for wind tunnel testing

    The 2.4m×2.4m wind tunnel is a system with the properties of strong nonlinear, multiple variables, serious coupling, large lagging, time-varying, etc. The complexity of all these phenomena makes the development of suitable dynamic Mach number models based on the aerodynamics laws very difficult. As an alternative, the Ensemble Neural Networks (ENN) model based on the feature subsets is proposed to address this problem. ENN built the sub-models on different lower dimension data sets, and reduced the complexity of the single Neural Networks (NN) built on the whole data set. Furthermore, a comparative study among the single NN models and the ENN models when used to predict the Mach number is conducted. Results show that the performance is improved by the ENN models. It is also shows that training time and testing time are much reduced by the ENN models.

  • Unsteady aerodynamics analysis for small amplitude pitch oscillations of transonic cruiser aircraft

    The behavior of the aircraft under oscillations in pitch, roll, yaw and plunge during the flight are crucial for the development of flight control systems and in determining the flight envelope of the aircraft. At present, the prediction of dynamic behavior of the aircrafts are mainly carried out using flight tests. These analysis at the last stage of aircraft development leaves least opportunities to make design changes and are expensive and time consuming. Till date Computational Fluid Dynamics (CFD) is not effectively used in this field due to the huge computational requirements to carry out the required studies and due to the lack of maturity of numerical tools to predict the involved unsteady flow features like highly separated flows. With availability of advance computing capabilities and maturity of CFD solvers, authors have put efforts to use full RANS simulations in carrying out the unsteady forced dynamic motion of the aircraft and compared it with the experimental data. And efforts are put to evaluate the flow physics predicted by CFD. This research paper presents CFD validation of low-speed small amplitude pitch oscillations test data for a Transonic Cruiser (TCR) Aircraft using Metacomp's CFD++ solver. The Stiffness and Damping of the Normal Force and Pitching Moment, estimated by Linear Regression Analysis (Least Squares) are in good agreement with the experimental data even in high angle of attacks.
