对Csa工程

Csa工程公司收到了国防部SBIR / STTR赠款项目的标题为:结构附件快速组装的卫星。抽象给这个项目如下:本研究的目的是开发低成本、模块化、多功能、主航天器结构使用胶合板和小的方法快速组装。这些结构是由铝facesheet /蜂窝芯材夹层板(胶合板)连着铝型材(小的)。结构需要简单的手工工具来组装和杠杆计算图表设计指南为基础所需的结构/热分级快速反应任务。平坦的三明治板集成到六角(箱)结构利用基本挤压形状结构之间的连接板。这种方法允许开放架构结构设计可伸缩的大小。保税总成包括紧固点附件的飞行传感器载荷(200公斤类)和支持子系统。由于这些结构是铝的基本组装提供了内在损害的鲁棒性;EMI和辐射功能;并允许多个热管理的水平。 These thermal management levels are: - The basic thermal continuity of the bonded aluminum panels and extrusions - Easily added custom heat straps to augment thermal paths within the bonded the assembly or at attached components - Direct interfacing to heat pipes at the mechanical hard points of the attached components. This study targets Air Force warfighter missions with satellite build processing within 8 hours. Csa Engineering is a company that received a Department of Defense SBIR/STTR grant for a project entitled: Optical Ground Vibration Test System. The abstract given for this project is as follows: An acquisition system that will greatly reduce the time to perform ground vibration tests (GVT) on military aircraft is proposed. The system will automate GVTs, enabling rapid acquisition without requiring setup of nearly all sensors and cabling. Segments of the wireframe geometry and acquisition setup will also be generated automatically. Aircraft down times will be reduced dramatically. The system will utilize one or more robotic carts with gimbal-mounted laser vibrometers, wireless accelerometers for degrees of freedom that are not line of sight, and potentially mobile shaker carts. A soft suspension system is also proposed for applications requiring low-frequency isolation. Custom software will drive robotic assemblies and port data from sensors to modal acquisition and/or reduction software.
