UAVsWhat is it? An Unmanned Aerial, or Air, Vehicle (UAV) is according to

MSN Encarta an "uncrewed reconnaissance vehicle: an uncrewed aerial vehicle that can fly over combat zones and staging areas, dropping supplies to troops, releasing bombs, carrying out reconnaissance on enemy forces."

Uses? Remote sensing Commercial aerial surveillance Oil, gas and mineral exploration and production Transport Scientific research Armed attacks Search and rescue

ObjectivesUtilize the knowledge learned in each phase of the course including conceptual design using engineering sketches, detailed design using Pro/ Engineer, and cost analysis and material list preparation using Excel to design a micro air vehicle

Design Details1. Structure and payload requirements A quick mount should be provided for a 20-g micro DVR. The maximum weight of the vehicle including payload should be

450 g.

2. Mode of flight requirements Ground takeoff and landing is required (no toss).

3. Power and propulsion requirements The vehicle must be able to fly for at least 5 minutes without

replenishing or recharging its energy source.

4. Control requirements The vehicle must be controlled by a 2.4G Hz radio

transmitter in a 50’x30’x20’ indoor space with smooth

floor. (The width of an NBA basket ball court is 50’)

Design Details cont.5. Mission requirements Endurance - fly as many figure 8 paths around two pylons

separated by 30’ in five minutes.

6. Cost requirements Total as-built replacement cost of the vehicle and the trainer

must be less than $250. The cost must be broken down in a Bill of Materials (BOM),

in which the Fair Market Value (FMV) of each component must be listed along with the part number, vendor and quantity.

7. Product deliverables The MAV. The preliminary design presentation (PowerPoint slide file) The final design presentation (PowerPoint slide file) The final printed design report.

Assembling the GWS Slowstick

For the assembly, our group met over a weekend and worked together at a team member’s house.

For the most part, we followed the instructions of the book given to us. We also improvised for some steps because of different parts.

ConclusionBy using the multiple aspects of Engineering we learned, including designing sketches, creating designs on Pro Engineer and creating Excel spreadsheets, we were able to create a micro air vehicle that fulfilled the requirements listed. In addition, our group members improved as problem solvers and team workers through this project. In the end, we accomplished our goal of creating a micro air vehicle that could take off on its own, stay in flight for 5 minutes on an energy source and land under its own power. The plane had the ability to fly in a figure eight shape as the rubric instructed.
