“…Force or momentum can be measured using multiple set-ups such as a ballistic pendulum [18], a Hopkinson bar [1,3,19], a spring in the form of calibrated beams [8], load cells [20][21][22][23][24][25][26][27][28], etc, all having their advantages and disadvantages. The actual shock behaviour and constitutive modelling of ballistic gelatine can be investigated using more fundamental set-ups such as the Hopkinson bar [29][30][31].…”

To validate the increasingly used numerical models for optimization and verification of the designs subjected to bird strike, initial (calibration) tests are a necessity prior to full scale testing. Bird strike calibration tests on rigid targets specifically, give a valuable insight in the complex behaviour of a bird. This paper presents the results of a series of bird strike tests and simulations on three rigid targets (a plate, a wedge and a splitter) to quantify the forces originating from the change of momentum and splitting of the bird. In this study, momentum transfer is the key parameter to compare birds with different masses, materials, speeds, etc., as proposed in the reference works from the 20 th century. The main purpose of this paper is fourfold: (i) to introduce another way to measure momentum transfer on these kinds of structures and therefore get more consistent results, (ii) to show that gelatine generates similar impact forces as real birds, (iii) to point out that apart from the change of direction of the momentum, the deviatoric and/or dissipating constitutive behaviour of the bird also plays an important role and (iv) to show that a simple plate structure can be used to measure the residual energy of the bird remainders after an impact event. In a series of numerical simulations, the performance of a SPH bird with an EOS material model is used to validate the analytical models.

“…The Boeing 787 is an example of a recently developed aircraft that incorporates many aluminum alloy and carbon composite components. 1 ) Recently, these materials have also been used in aircraft jet engines. For example, the GE90 (General Electric) has fan blades made of carbon fiber (CF)/epoxy composites.…”

An aircraft may suffer from foreign object damage (FOD) during flight operations, and a bird strike is a potentially serious and damaging FOD event. For simulated bird strike experiments, gelatin has been traditionally used as the projectile material. However, it has not been sufficiently determined how the material properties of the projectile affect the simulated bird strike results, especially for deformable targets. In this work, using gelatin as the conventional simulated bird material, silicone resin is used to investigate the effects of the projectile material properties. Two types of impact tests are conducted. One uses a solid target with a flat face, and the pressure change due to the impact is investigated. The other uses a cantilever target made from aluminum alloy or carbon fiber/epoxy composite laminate to investigate the plastic deformation or damage, respectively. From these experiments, the effects of the projectile material type and properties are evaluated.
