Dynamic Load Analysis of C295

PROJECT DATA

• Client: AIRBUS MILITARY
• Technology: Dynamic Load Analysis

DESCRIPCIÓN

The C295 is a twin engine tactical military aircraft for military transport, maritime patrol and submarine warfare. Different variants have been developed of the Basic C295 since it was introduced in 2001, where ICEMM has worked in all variants since 2007 in the area of Structural Dynamic & Aeroelasticity defining the dynamic loads of the aircraft in the preliminary design phase and the certification phase.

C295 Discrete Gust Loads

TECHNOLOGY

All analyses have been performed using the Finite Element Method with the assistance of the MSC.NASTRAN software and in-house EADS-CASA software for post-processing of loads:

• Normal modal analysis
• Dynamic Transient analysis
• Random analysis
• Aeroelasticity

The pre-processing, optimization and automation of the dynamic load loop has been performed by means of Unix Shell and Python Scripts.
