Unmanned aerial systems (UASs) can only be deployed if they can effectively complete their missions and respond to failures and uncertain environmental conditions while maintaining safety with respect to other aircraft as well as humans and property on the ground. In this paper, we design a real-time, on-board system health management (SHM) capability to continuously monitor sensors, software, and hardware components for detection and diagnosis of failures and violations of safety or performance rules during the flight of a UAS. Our approach to SHM is three-pronged, providing: (1) real-time monitoring of sensor and/or software signals; (2) signal analysis, preprocessing, and …

Creating Low-Cost ‘Balloonsats’ For Stem Education With 3d Printing, Jeremy Straub May 2013

Creating Low-Cost ‘Balloonsats’ For Stem Education With 3d Printing, Jeremy Straub

Jeremy Straub

A new technology, known as 3D printing, allows the rapid fabrication of plastic structures of virtually any configuration. These structures are light-weight, durable and inexpensive. This paper considers the utility of utilizing 3D printing to create enclosures for ‘BalloonSats’ – small, low-cost spacecraft analog which can be utilized by students to understand space engineering, conduct near-space science (e.g., physics, biological and other experiments) and touch the edge of space.

The utility of 3D printed structures for use in the near-space low-temperature and low-pressure environment is considered. This analysis falls into four key areas. First, the ability of the structures to …
