Simulation of the behavior of a payload fairing during separation
The present paper describes the development of a finite element based tool at the launcher directorate of the French Space Agency (CNES) in order to support the ground study and testing of fairing separation systems. The main topic is the finite element modeling process and its validation. The considered finite element methods and resolution algorithms are presented, with a focus on shell eleme...
متن کاملDecentralized Vibration Control in a Launch Vehicle Payload Fairing
* Member ASME ABSTRACT The vibro-acoustic environment inside a launch vehicle payload fairing is extremely violent resulting in excessive development costs for satellites and other payloads. The development of smart structures and active noise and vibration control technologies promised to revolutionize the design, construction and, most importantly, the acoustic environment within these fairin...
متن کاملNoise Reduction of a Rocket Payload Fairing Using Tuned Vibration Absorbers with Translational and Rotational DOFs
Numerical optimisations were conducted to reduce the noise levels inside the payload bay of a rocket by using vibration and acoustic absorbers attached to the fairing walls. The vibration absorbers act in both translational and rotational axes. The acoustic absorbers were modelled as simplified Helmholtz resonators. A Finite Element model of the vibro-acoustic system was created in ANSYS and th...

متن کاملDiscrete Fairing
We address the general problem of, given a triangular net of arbitrary topology in IR 3 , nd a re ned net which contains the original vertices and yields an improved approximation of a smooth and fair interpolating surface. The (topological) mesh re nement is performed by uniform subdivision of the original triangles while the (geometric) position of the newly inserted vertices is determined by...
