Decentralized 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 کاملPre-Launch Characterization of the WISE Payload
The Wide-field Infrared Survey Explorer (WISE), launched in December 2009, is a NASA-funded Explorer mission that is providing an all-sky survey in the mid-infrared with far greater sensitivity and resolution than any previous IR survey mission. The Utah State University Space Dynamics Laboratory designed, fabricated, and characterized the science payload, which is a cryogenically cooled infrar...
متن کاملSelf-scheduled and structured H⋡ synthesis : A launch vehicle application
This paper presents a new application of structured H∞ synthesis to tune self-scheduled controllers. Newly available MATLAB-based tools allow to tune fixed-structure linear controllers while satisfying H∞ constraints. Moreover multi-model synthesis capabilities can extend their application to self-scheduled controllers. This technique is successfully applied to the attitude control of a launch ...
متن کاملMaterials for Launch Vehicle Structures
This chapter concerns materials for expendable and reusable launch vehicle (LV) structures. An emphasis is placed on applications and design requirements, and how these requirements are met by the optimum choice of materials. Structural analysis and qualification strategies, which cannot be separated from the materials selection process, are described. A launch vehicle is an airborne system tha...
متن کاملAlternative Space Vehicle Launch Systems
Over the last century chemical propellants have been the dominant fuel source for the aviation and aerospace industry, primarily because they are able to provide ample power for a limited cost. However, over the last decade as the price of chemical propellant continues to soar and their detrimental effect on our environment comes to light, there has been a surge to develop an alternative propul...
