  • Characterization of a 3DOF aeroelastic system with freeplay and aerodynamic nonlinearities – Part I Higher-order spectra Reviewed

    118   781 - 807   2019.3

     More details

    Language:English   Publishing type:Research paper (scientific journal)  

    The identification of nonlinear systems in aeroelasticity poses a significant challenge for practitioners, often hampered by the complex nature of aeroelastic response data which may contain multiple forms of nonlinearity. Characterizing and quantifying nonlinearities is further hampered when the response is obtained at a location which is away from the nonlinear source and/or the response is contaminated by noise. In the present paper, a three-degree-of-freedom airfoil with a freeplay nonlinearity located in the control surface and exposed to transonic flow is investigated. In this Part I paper the main form of analysis is via higher-order spectra techniques to unveil features of the nonlinear mechanism which result from i) structural nonlinearities (freeplay) in isolation and ii) freeplay with Euler derived nonlinear inviscid aerodynamic phenomena (transition between Tijdeman Type-A and Type-B shock motion). It is shown that the control surface structural freeplay nonlinearity is characterized by strong cubic phase-coupling between linear and nonlinear modes. On the other hand, nonlinear inviscid flow phenomena are shown to be characterized by quadratic phase-coupling between linear and nonlinear modular modes, the strength of which is related to the strength of the aerodynamic nonlinearity (amplitude of the shock motion). The nonlinear inviscid flow phenomena do not appear to affect the identification of the freeplay nonlinearity. Conjectures are made which address the transition between aperiodic, quasi-periodic and periodic behavior (pre-flutter), further physical support towards these conjectures is provided in Part II [1]. The limitations of the higher-order spectra approach are assessed, in particular, the analysis demonstrates the difficulty in extracting natural frequencies with this approach.

    Language:English   Publishing type:Research paper (scientific journal)  

    The Hilbert–Huang Transform is used to analyze the nonlinear aeroelastic response of a 2D 3DOF aeroelastic airfoil system with control surface freeplay under transonic flow conditions. Both static and dynamic aerodynamic conditions, i.e., for accelerating freestream speed, are considered using a linearized aerodynamic model. The main aim of this paper is to provide an in-depth physical understanding of the observed transition between periodic and aperiodic behavior, and the presence of a stable periodic region well below the domain characterized by stable limit cycles. Physical insights towards the forward and backward abrupt transition between aperiodic/chaotic and periodic behavior types appear to be the result of an internal resonance (IR) phenomenon between linear modes followed by a lock-in between linear and nonlinear modes. More specifically, initially a 2:1 IR between linear modes leads to a shift in the frequency composition and dynamic behavior of the system. A secondary effect of the IR can be observed immediately after the exact point of 2:1 IR such that a nonlinear mode locks into a subharmonic of the linear mode which in-turn drives a finite stable periodic region.

    The authors regret that an error was identified in the expression of the mixing vorticity efficiency defined in Eq. (5) of the article. The correct expression is [Formula presented], where the effective injector diameter D must be in the numerator rather than in the denominator according to dimensional analysis. The author regrets this error, while the correct definition was used for the calculation of mixing vorticity efficiency in the study, and so this correction does not affect the results, discussions, or conclusions. The authors would like to apologise for any inconvenience caused.

    Hypersonic air-breathing propulsion, in particular, scramjet (supersonic combustion ramjet) engines, is a promising technology for efficient and economical access-to-space and atmospheric transport. Axisymmetric air intakes based on the Busemann geometry offer appreciable efficiency with maximum total pressure recovery and minimum shock loss, but the inherently long geometry incurs large skin friction drag and structural weight, requiring shortening by some means. Two distinctly different configurations of Mach reflection are found to exist at the centerline for identical inflow conditions and intake lengths in the course of shortening by axial contraction (stunting). Parametric studies with steady and transient numerical simulations are performed to examine the inviscid transient flowfields with variations in the shortening length and freestream Mach number. This paper presents the results and flowfields with focus on the variations of the exit Mach number and temperature as well as intake drag and discusses the hysteresis observed in the stunting and reverse (stretching) process of the Busemann intakes.

    The identification of nonlinear systems in aeroelasticity poses a significant challenge for practitioners, often hampered by the complex nature of aeroelastic response data which may contain multiple forms of nonlinearity. Characterizing and quantifying nonlinearity is further complicated when the dynamic oscillations are of a high–amplitude limit cycle form, masking the underlying nonlinear contributions. In the present paper, a three– degree–of–freedom airfoil with freeplay in the control surface and transonic aerodynamics is investigated. The main form of analysis is via higher–order spectra to unveil the form of nonlinearity that i) freeplay with linearized aerodynamics and ii) freeplay with nonlinear inviscid aerodynamic phenomena will produce. It is shown that the freeplay nonlinearity with linearized aerodynamics is characterized solely by cubic interactions, i.e., the quadratic interactions are negligible. However, when considering the Euler-based CFD simulations, as the amplitude of the of the oscillations increases and Type-B shock motion becomes more apparent, the strength of the quadratic interactions becomes prominent. The findings demonstrate how the interaction between the different types of nonlinearity and the different solution methods affect the nonlinear spectral content of the system and how different forms of nonlinearity can be characterized by their higher–order spectra.
