* Wind Tunnel Projects (a'la the Shepard Test Stand)
8 9 Matt Maier
** The CCL mentions wind tunnels. 
9 9 Matt Maier
** 9B005 is for the controls/instruments "_9B005 On-line (real time) control systems, instrumentation (including sensors) or automated data acquisition and processing equipment, specially designed for use with any of the following wind tunnels or devices (see List of Items Controlled)_"
10 9 Matt Maier
** 9B105 is for the wind tunnel itself "_9B105 Wind tunnels for speeds of Mach 0.9 or more, usable for "missiles" and their subsystems_"
11 9 Matt Maier

* survey all of the rocket aerodynamics software and rank by utility, ease-of-use, and openness
13 5 J. Simmons
* port J's masters thesis on fin flutter analysis/optimization to open source tools
14 5 J. Simmons
* parametric #CodeCAD models of fins (suitable for 3D printing, milling, and drafting)
15 6 Greg Moran
* Practice/document manufacturing processes for aero structures, hotwire for foam, cutting balsa for fins, 3D printing, etc
16 6 Greg Moran
* Build a computing cluster
17 6 Greg Moran
* Make the computing cluster opt-in (from donated hardware/time)
18 6 Greg Moran
* Study/research impact of surface finish on aerodynamic surfaces
19 6 Greg Moran
* Research/study aerodynamic “fixes” (like trip lines, vortex generators, etc)
20 6 Greg Moran
* Visualization tools/processes for aerodynamic phenomenon/flows (smoke, pressure sensitive paint, streamers, Schlieren)
21 6 Greg Moran
* Scaled composites style wind tunnel by “car/truck”
22 6 Greg Moran
* How fast of a wind tunnel is reasonable to build?
23 6 Greg Moran
* Design processes for wind tunnels by target regime
24 6 Greg Moran
* How to’s for wind tunnel analysis (things like dealing with Reynold’s number etc to properly scale test articles)
25 6 Greg Moran
* Using other “tricks/hacks” to do wind tunnel style tests (UAVs, mounting to model rockets, etc) <- expands the car idea above
26 6 Greg Moran
* Software tools for aero stability (not controls or guidance)
27 6 Greg Moran
* Laboratory measurement software and equipment, especially distributed viewers of a test to remote locations
28 6 Greg Moran
* Research/study impact and limits on externally mounted features (like antennas, etc) on aerodynamic performance (flow perturbation analysis)
29 8 J. Simmons
** see NACA Aerodynamic DB (subsonic), see NASA for supersonic
30 8 J. Simmons
** can document how to use sources like that including doing a flight test with a model rocket
31 6 Greg Moran
* Hydro tunnel projects
32 6 Greg Moran
* Cheat sheet/booklet/software for aerodynamic calculations (Cd/Cl build up to go from design to rough estimate of total Cd/Cl)
33 6 Greg Moran
* Add ability to include environmental impact (rain, fog, etc) to wind tunnel to test performance under all weather conditions
34 6 Greg Moran
* Aerodynamic analysis/design of a stable recovery system for payload module in case of vehicle failure (no thrusters or parachutes, like a seed pod)
35 6 Greg Moran
* Investigate using OpenVSP for model/high power rocket design/layout
36 6 Greg Moran
* Extend analysis of aero stability and aero characteristics software and calcs to include subsonic, transonic, and supersonic regimes
37 6 Greg Moran
* Investigation of aerodynamic mechanisms (glider wings, canard fins, etc)
38 6 Greg Moran
* Simulate/study aero-structural analysis (include aeroelasticity, etc)
