Impact Simulation With an Aircraft Wing Using SPH Bird Model
Journal Title: INCAS BULLETIN - Year 2015, Vol 7, Issue 3
Abstract
The work presents an approach to simulate a model bird-strike on an aircraft wing using Lagrange mesh free method in Autodyn. The presented SPH model has been used to simulate a threedimensional impact of the bird with the aircraft wing, at different angles, at a velocity of 262,22m/ s. The bird was modeled as a fluid cylinder with two hemispherical ends representing a commonly used shape in the numerical studies of bird strike. The main objective was to identify the safe impact velocities for which the wing is not damaged.

Calculus of axial force in a mechanism using Lagrange equations
Lagrange equations are used to study the motion of a system under the action of known external forces. Besides, based on these equations we can determine the internal force in an arbitrary element of the mechanism acting...

An Interpretation of the “Black Energy” in Universe by Using a Hydro-Dynamical Analogy with Newton Gravity
There are arguments proving that what we see now as “normal energy” (including the equivalent mass-energy) represents only 5% of the total energy of the Universe [1]. The rest is invisible meaning that no widely accepted...
