متن کاملInternational Bird Strike Committee
Aircraft repeatedly prove that birds and aircraft cannot occupy the same airspace at the same time. In an average year about 3000 birdstrikes cause 50-80 million US dollars in damage to USAF aircraft. To the worldwide aviation fleet this problem is estimated to cost more than three billion US dollars per year. Factors for consideration in establishing birdstrike resistance requirements, and in ...
متن کاملLow Velocity Impact Damage Prediction in Laminated Composite Plates
In this paper, a finite element model is presented for the transient analysis of low velocity impact, and the impact induced damage in the composite plate subjected to low velocity impact is studied. The failure criteria suggested by Choi and Chang and the Tsai-Hill failure criteria are used for the prediction of the damage in the composite plate; then the effect of various parameters on the im...
متن کاملMultiscale Approach to Damage Analysis of Laminated Composite Structures
The presented work depicts results of a two-scale approach to the problem of damage and failure prediction on laminated composite structures. Modeling on the micro-level has enabled insight into the underlying physical processes which lead to homogenized properties of the macro-scale material. In this work, micromechanical analysis has been performed by application of the High Fidelity Generali...
متن کاملThe Costs of Bird Strikes and Bird Strike Prevention
Collisions between birds (and other wildlife) and aircraft are known to cause substantial losses to the aviation industry in terms of damage and delays every year. Techniques exist to control bird numbers on airfields and hence to reduce the number of wildlife strikes, but they are applied at widely different levels from airport to airport. Some of this variation may be due to differing levels ...
