Modeling, Analysis, Control and Performance-Based Design of Micro/Nano Aerial Vehicles (MAVs/NAVs). In short, we expect MAVs/NAVs to revolutionize mobile sensing, intelligence gathering and warfare.
As such, crafted the following research plan:
LITERATURE SURVEY. Complete comprehensive literature survey (already initiated).
MODELLING. Develop low and moderate fidelity dynamical models for specific MAV configurations to be examined (i.e. conventional helicopter, tilt-wing rotorcraft, and flapping-wing). The models to be developed will be based upon first principles as well as CFD. These models should be useful for both static (e.g. equilibrium L/D) as well as dynamic performance analysis (e.g. instabilities, right half plane poles, flexible/other modes). It is understood that unsteady aerodynamics and vorticity effects are particularly important for flapping-wing configurations.
TRADE STUDIES. Conduct trade studies (e.g. lengths, widths, masses) to reveal mission critical (static and dynamic) performance limitations. The selected “benchmark” missions will be based on our literature survey (e.g. hovering, low-speed maneuvering and loitering, cruise).
PROTOTYPE. Build prototype MAV – including airframe, actuators, sensors, processing, other instrumentation for validation phase, etc.
VALIDATION. Conduct experiments to gather performance data from prototype. The data will then be analyzed and carefully compared with model-based simulation data. This is expected to result in modifications to the original model.
MINIATURIZATION. Develop initial miniaturization plan.
The proposed research will directly address critical performance-based vehicle design issues for MAVs/NAVs. Results will be nationally disseminated via journal/conference papers and the www (http://aar.faculty.asu.edu/). It will also be made available to roughly 150 STEM students (mostly women and underrepresented minorities) per semester that I advise under other NSF STEM-CSEM-STEP grants - an activity that directly impacts community college/high school students/faculty across the state of Arizona. The proposed work is also expected to significantly enhance the ongoing nano technology work at ASU.

Wings are the most difficult to build. The glue sticks close to everything. Scraping the glue off the plastic is a pain. Major process for. THe valves on the
back glued shut so had to redue the process. Glueing the plastic on the carbon fiber. Maybe a need for a slower glue is needed to not stick everything together.
The read valve has plastic loose pieces to allow air flow through it, the rods keep the plastic being suck from the wing. Need to buy a tube of glue.
Buying a PIV laser
Laser is most expensive... I got a used one after a lot of looking... about $35,000 for that alone. A camera costs about $10,000. And then you have to have the software... which since we bought the TSI V3V system we got that -- but the better the software the better your data... A minimum of $50,000 for a system like ours.

The below proposal provides the Gyraphon group with a single uninterrupted 1.5 hrs which should be enough time to focus on building their bird. Since the balsa planes are a lot less difficult, this session is broken up into two different sessions of 45-min each. I also moved up the snack a little so the times flowed a little smoother.
Schedule
8:00 - 8:50 Set up (rooms, computers, check-in ect.)
8:45 - 9:00 Student Check in
9:00 - 9:45 Gyraphon Group: Critical Thinking Session w/ Karen Crawford

next 5 weeks for the Balsa Wood Plane Group:
Each week, I will introduce the main concepts of the week during the first 30-45 minutes (depending on schedule) with a presentation and/or video. This Saturday, I will be distributing notebooks so each student can record the learning goal from each week and their reflections of how the understood the goal. This information will be need to be incorporated into their poster presentation at the end of the program.
The concept plan for each week is as follows:
Week 1 (March 23rd) - Weight & Lift: Foam airplanes vs. balsa wood vs paper plane
Week 2 (April 6) - Resistance (thrust/drag): Mono-plane vs Bi-plane or propeller plane
**Week 3 (April 13) - Speed: Mono-plane vs Bi-plane or propeller plane
Week 4 (April 20) - Design: Art day for poster creation and decorated balsa wood air plane
Week 5 (April 27)- Competition: For my section there will be 3 separate parts of the competition (1) Each student will have a poster presentation showing what they learned during the program (2) Students will have a custom designed balsa-wood plane that they will have to show and describe their artistic design (please note, plane must still fly to be successful) and last (3) each student will compete in the general plane competition for longest air- time, farthest flight (distance) using their chose of a foam plane, mono, bi or propeller balsa wood plane.
