TLDR
In this article, the authors carried out bird strike analysis and tests of a blade antenna of an aircraft, and the results of the analysis and test showed that they had a positive relationship.Abstract:
The objectives of this study is to carry out Bird strike analysis and tests of a blade antenna of aircraft. FEMs (Finite Element Models) were created for the analysis, while dummy and real antennas were used for the bird strike tests. In the analysis, birds were modeled with SPH (Smooth Particle Hydrodynamics) method, and the behaviors of the bird, antenna, and joint structure between antenna and aircraft fuselage were simulated with the FSI (Fluid-Structure Interaction) method. After the bird strike test was performed, the results of the analysis and test showed that they had a positive relationship. The damage of antenna and bolted joint was checked, and the structural integrity of the airframe was proved. 초 록 항공기의 블레이드 안테나에 대해 더미와 실 안테나의 조류충돌 해석과 시험을 수행하였다 해석에서 . 조류는 방법을 이용하여 모델링하였으며 유체 구조 연성해석 SPH(Smooth Particle Hydrodynamics) , (FSI, 기법으로 조류와 안테나 기체 체결부의 거동을 시뮬레이션 하였다 실제 조류 Fluid-Structure Interaction) , . 를 사용한 시험을 수행하여 안테나와 동체 사이의 체결부 손상 및 이탈여부를 확인하였으며 항공기 기 , 체의 구조건전성과 해석 및 시험 결과 사이의 상관성이 있음을 입증하였다.read more

Impact Behavior of Low Strength Projectiles
TL;DR: An unsteady, hydrodynamic model of the impact of a low strength projectile on a rigid or semi-rigid target has been developed and impact tests of various materials including birds, gelatin, and RTV rubber have been conducted to validate this theory.

The Development of a Substitute Bird Model
James S. Wilbeck,James L. Rand +1 more
TL;DR: A comprehensive program was conducted to develop a model synthetic bird for use in engine blade impact testing and it was determined that a projectile fabricated from commercial gelatin impregnated with phenolic mircoballoons most nearly duplicated the impact loading history of real birds.
Validation of Available Approaches for Numerical Bird Strike Modeling Tools
TL;DR: In this article, the authors investigate the bird strike phenomenon in order to validate available numerical models through experimental tests and simulation tools and describe how to use the currently available test data while exerting caution as to their reliability.
Finite element analysis of bird strikes on composite and glass panels
TL;DR: In this paper, the authors propose a method to solve the problem of "uniformity" and "uncertainty" in the context of health care, and propose a solution.
