Flutter Analysis Walkthrough
FEMAP Flutter Analysis Example This example will demonstrate how to create the "Aerodynamic model" and specify some analysis parameters used to perform a flutter analysis using NX Nastran. Topics discussed will be: Create an "Aero Panel" (CAERO1 and ...
5 Things You Should Know About Flutter
Ben Names Sr. Stress Engineer If you like this article, be sure to check out my webinars: Introduction to Aeroelasticity in Nastran - This recording includes a demonstration of Aerodynamic Flutter, a static aeroelastic analysis, and the benefits of ...
Generating Aerodynamic Loads | Hand Calculations vs. Aeroelasticity
Within the Aerospace Engineering community, there is an entire sub-discipline devoted to understanding the dynamics of a system and generating loads (propulsive, inertial, aerodynamic, etc). In smaller companies, engineers often need to wear multiple ...
Shock Response of a Composite Overwrapped Pressure Vessel
A composite overwrapped pressure vessel (COPV) is a tank that holds propellant for space vehicles. The scale of COPV’s can range by a couple orders of magnitude. Throughout a typical mission, these tanks can be subjected to shock/impulse loads ...
An Update to the State of Composite Buckling in NX NASTRAN
Introduction This article is written by Ben Names and is a continuation of a previous white paper, “The State of Composite Buckling in NX Nastran,” with some updated findings and conclusions. Earlier I posted a white paper addressing some of the ...
