Production Technique of a Bird Imitator for Testing Structural Optics to withstand Impact by Birds

Description

Actual tests of airplane structural components to withstand impact by birds are carried out, as a rule, with the use of birds’ carcasses or with the help of equivalent imitators.

Developed by IPMash of NAS of Ukraine imitator of principally new construction for certain imitates impact parameters produced by a bird during a barrier blow, that is proved to be true by actual comparison tests for various angles and speeds of collision.

A bird imitator is a cylinder connected with hemispheres. Geometry of the imitator: length cm, diameter cm. It is made of silicone, elastic properties and density of which are similar to muscle tissue characteristic of a bird (1,1 г/см3). Lengthwise the axis of the imitator there is an element of construction modelling skeleton and cavities inside a bird that allows to reach average density of the imitator according to average density of a bird (0,93 г/см3).

Application of the bird imitator allows to simplify an experimental technique, to cut down expenses and time for exploratory design and actual tests.

Innovative Aspect and Main Advantages

In comparison with analogues it has several advantages:

  • close to reality reproduction of an impact by bird to a structural component;
  • simplicity of the technology and acceptable production cost;
  • long working life under room temperature;
  • applying non-polluting materials;
  • compliance to hygiene and sanitary conditions and aesthetic norms;
  • imitator’s remnants are easily utilized.

Areas of Application

Aircraft industry of Ukraine, Russia and other countries of the world.


Stage of Development

The development is completed and ready to application, Ukrainian patent is obtained, and a positive decision of Russian patent grant is made. Pilot batch of imitators is made and comparison actual tests are successfully conducted.
