Multidisciplinary Design Optimization of Composite Spacecraft Structures using Lamination Parameters and Integer Programming
… and enabling the optimization of complex spacecraft structures. Since the design team consists of multiple entities from different domains working together to build the final product, the design and analysis tools must be readily available and compatible. An integrated approach is required …

Simulating Space Radiation for Testing Shielding Material Effectiveness
… accurate evaluation of the shielding effects of spacecraft structures on the incoming space radiation environment. Since the complicated shielding geometry plays an important role, existing transport codes must be improved to predict dose deposition inside the vehicle. Computer simulations of …

High-temperature superconductors as electromagnetic deployment and support structures in spacecraft
… and increasing the stowed-to-deployed ratio of spacecraft systems. This technique uses the magnetic fields generated by high-temperature superconductors (HTSs) to support spacecraft structures and deploy them to operational configurations from stowed positions inside a launch vehicle fairing. …

Acoustic Analysis of Spacecraft Cavities using the Boundary Element Method
Spacecraft structures are subject to a series of load environments during their service life, with the most severe of these occurring during the spacecraft's launch and ascension through the atmosphere. In particular, acoustic loads imposed on stowed satellites within the launch vehicle fairing can …

Failure Prediction of Honeycomb Panel Joints using Finite Element Analysis
Spacecraft structures rely on honeycomb panels to provide a light weight means to support the vehicle. Honeycomb panels can carry significant load but are most vulnerable to structural failure at their joints where panels connect. This research shows that predicting sandwich panel joint capability …

Optimal control co-design of attitude control systems
Attitude control is the process of orienting a spacecraft toward a desired point in space. Conventional systems for attitude control have been designed without considering the compliant response of the spacecraft. This leads to complex control algorithms that avoid exciting vibrational modes of the …
