Simulation of the behavior of a payload fairing during separation
نویسنده
چکیده
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 element formulations in the used finite element packages. The model results are compared with those obtained for a separation system with a pre-existing model and a ground test. The developed model shows good agreement with the reference results and enables the CNES to fulfill its technical support role.

Active Structural-Acoustic Control for Composite Payload Fairings
1 Launch loads, both mechanical and acoustic, are the prime driver of spacecraft structural design. Passive approaches for acoustic attenuation are limited in their low frequency effectiveness by constraints on total fairing mass and payload volume constraints. Active control offers an attractive approach for low frequency acoustic noise attenuation inside the payload fairing. Smart materials s...

متن کاملCooperative Control of Multiple Quadrotors for Transporting a Common Payload
This paper investigates the problem of controlling a team of Quadrotors that cooperatively transport a common payload. The main contribution of this study is to propose a cooperative control algorithm based on a decentralized algorithm. This strategy is comprised of two main steps: the first one is calculating the basic control vectors for each Quadrotor using Moore–Penrose theory aiming at coo...

In this paper, a new steganography scheme with high embedding payload and good visual quality is presented. Before embedding process, secret information is encoded as block using Reed-Muller error correction code. After data encoding and embedding into the low-order bits of host image, modulus function is used to increase visual quality of stego image. Since the proposed method is able to embed...
متن کاملAn Adaptive-Robust Control Approach for Trajectory Tracking of two 5 DOF Cooperating Robot Manipulators Moving a Rigid Payload
In this paper, a dual system consisting of two 5 DOF (RRRRR) robot manipulators is considered as a cooperative robotic system used to manipulate a rigid payload on a desired trajectory between two desired initial and end positions/orientations. The forward and inverse kinematic problems are first solved for the dual arm system. Then, dynamics of the system and the relations between forces/momen...
