An Analysis of the Engineering Challenges Presented
by Inflatable Systems for Space Applications
Deployable structures for space applications are frequently desirable solutions to mission requirements but often come with significant engineering challenges. The TARGIT CubeSat mission needed a large structure with a known shape and reflectivity to validate its onboard LIDAR system. An inflatable structure attached to the spacecraft by an extendable tether is a good solution to this requirement. It is relatively lightweight and utilizes minimal volume while stowed to produce a large structure with a known shape and reflectivity after inflation. However, creating a thin, stowable, and pressurizable system to be used in a vacuum presents many complexities. This presentation will discuss the design, manufacturing, and regulatory challenges that were overcome to develop the inflatable system for TARGIT and the significance of these findings for future space applications.

Computational Modeling of Airfoil Performance Under Rain Conditions
Abstract: It is known that rainfall, and the formation of water on airfoil surfaces can dramatically impact the lift production of airfoils, as well as greatly increase the drag. While large scale airfoils, typically found on aircraft, are not significantly affected by the surface water layers that are only a few millimeters thick, rainfall can profoundly affect the performance of small chord length airfoils found on vehicles such as small-scale drones and eVTOL machines. This semester’s work has consisted of computational studies performed on the effects of rainwater on the lift and drag characteristics of such small-scale airfoils. A parametric study was conducted to quantify the loss in lift and rise in drag as a function of airfoil shape, angle of attack, Reynolds number, droplet diameter, and the rainfall rate. Comparisons with available test data were made.

Mechanical Design of Unmanned Aerial Vehicles Systems
The Intelerligent Robotics and Emergent Autonomy Lab at Georgia Tech conducts research in vehicle design, dynamic analysis, and control systems – aiming to improve actively-controlled robotic systems. This presentation will outline multiple systems improved on the iREAL lab through a variety of projects that were completed over the past two years. It will begin with an in-depth overview of how the system was envisioned and designed, with emphasis on the design for manufacturing. Then, the project construction and timeline will be introduced alongside analysis on manufacturing updates made throughout the process. The presentation will be rounded out by discussing future concerns and solutions, as well as lessoned learned. Overall, this presentation will discuss system improvements to UAV systems with the optimal design methods and decisions.
