Bird Strike - Project - 2

AIM:           

      In this challenge, we need to a create simulation of a Bird crashing with the Fan Blades of an Aeroplane Propeller.

Theory:

         In this project, we are going to analyze the Blade of a plane, how it's reacting for a Bird model.

 PROCEDURE:

     1. Bird - Hexa Meshed model, which will represent the Bird for this simulation.

          2. Hub - This will connect the Blade with Rotor.

      3. Blades - These blades will have rotational motion, which provides the necessary thrust.

        4. Casing - This is the Outer Cover for the Blades.

     Material need to be created for all parts.

              MAT_24 is given in question for BIRD

                  Create SECTION_SHELL for bird/casing/Bird ....SOLID for HUB

               Create INITIAL _VELOCITY for Bird-Blade

                 Create CONTACT for all parts.

                  Create DATABASE

                    Create CONTROL_Termination.

                  Create DEFINE_CURVE.

                     Create BOUNDARY_SPCSET for casing to avoid movable 

            Need to create RENUMBERING FOR ALL PARTS.

              This ERROR_need toobe Rectified.

   CONCLUSION:

              In this Simulation, Bird is Assigned with Elastic Material and with general Properties, thus the results Obtained From the simulation can not be compared with the Real-time Data. Generally, The Bird will be modeled with Smooth Particle Hydrodynamics (SPH), which replicates the simulation similar to the real Bird. The Material Properties might vary according to the Blades used By different organizations and it can be solved and results can be compared. Mass Scaling is performed and obtained the results are maintained as less than 8%. All the subsystems were created and included with the Main file. Transient-non linear bird strike application is done by using LS-Dyna. The contour plots and global results are sketched.
