Nonlinear Coupled Loads Analysis

ASD has conducted numerous of nonlinear coupled loads analyses for our clients.

Space Shuttle Mission 1E Nonlinear CLA (Lockheed Martin, NASA): Impact of component interface deadbands
Space Shuttle Mission 13A.1 Nonlinear CLA (Lockheed Martin, NASA): Impact of component interface deadbands
Space Shuttle Mission 2J/A Nonlinear CLA (Lockheed Martin, NASA): Impact of component interface deadbands (NCLA Brief)
Comparison of ASD’s nonlinear transient capability to test data (Lockheed Martin, NASA, Jacobs)
Constellation CLAs (NESC, NASA/Langley): ASD was tasked to conduct nonlinear CLAs in support of the MLAS alternate astronaut escape system for the Orion spacecraft. The CLAs involved flight vehicle separation from the launch stool at multiple cant angles utilizing the Henkel-Mar pad separation method. Other nonlinearities included 8 circumferential snubbers between the forward fairing and the crew module.
