  • experiment and numerical simulation of a full scale helicopter composite cockpit structure subject to a bird strike
    Composite Structures, 2016
    Co-Authors: Bin Song, Dongfang Wang, Zuyong Chen
    Abstract:

    Abstract Bird strike is one of the most critical safety issues in aviation, which usually leads to catastrophic casualties. In this paper, an effective FE–SPH coupling model is developed to investigate the structure crashworthiness performance of a helicopter composite cockpit (HCC) subject to a bird strike by using an explicit nonlinear finite element code ANSYS/LS-DYNA 3D. The mechanical parameters of the bird constitutive model are obtained by a bird strike test on flat plate and the validated bird model is subsequently implemented to simulate a bird striking on HCC according to Federal Aviation Regulation 29.631. A full-scale HCC bird strike experiment is also performed under the same impact condition to certify Airworthiness Requirement as well as validate the FE model. The high agreement between the experiment and numerical analysis builds confidence in future use of FE method as a predictive tool. Based on numerical results, a structure design modification is also performed to enhance the structure stiffness and improve bird strike resistance.

  • safety evaluation of Airworthiness Requirement of bird strike on aeroplane
    Engineering Failure Analysis, 2019
    Co-Authors: Jing Cai, Han Bao, Hongfu Zuo, Yan Huang
    Abstract:

    Abstract Bird-strike is a potentially serious and damaging event, and the environment of bird flock and the design of anti-bird-strike have a significant effect on the probability and criticality of bird-strike. Therefore, the relationship among the environment of bird flock, the design of anti-bird-strike and risk Requirement is illustrated firstly from the view of Airworthiness. Secondly, in order to describe the characteristic of bird flock, the distribution of impact energy of bird-strike under the environment of bird flock in China are obtained and verified with twofold two-parameter mixed Weibull model. Finally, the quantitative relationship between risk Requirement and sustainable bird-strike weight are determined to evaluate the Airworthiness Requirement of bird-strike. As an example, the existing Airworthiness clause of bird-strike for the vertical stabilizer is evaluated. The proposed safety evaluation method in this work not only can help revise the Airworthiness clauses of bird-strike based on a special bird flock environment, but also guide the design of anti-bird-strike.
