- Power / Propulsion
- Acquired more NiCd batteries from Professor Mason
- Continued to test batteries for output
- Disassembled F-18 model and took the servos and electronics for use on this project
- Purchased 40 Amp brushless speed controller
- Dual BEC and advanced programming
- Dimensions: 50mm x 26mm x 10mm
- 20 gram mass
- Purchased propellor motor
- Neodym 480-900 kV motor
- More information on this and other Neodym products can be found at Neodymmotors.com
- Purchased propellor
- Dimensions: 9 inches x 6 inches
- Determined the thrust being put out by new propellor-motor system using logger-pro
- 1.1 +/- .1 Newtons
- Note: 11.1 Volts and 1.13 Amps were used to power the system
- Airfoils / Airframes
- Developed a new wire cutter to allow bigger pieces of foam to be cut
- Continued building different types of wings
- It was determined that the tips of the wings should not be too thin, as the wire cutter seems to butcher these ends when cutting through the foam
- Began work on building a working trainer model
- Frame drawn, cut out, and sanded
- Ailerons cut out
- Continued work on optimizing the scoring function to determine the best design
Week four will focus on the following things:
- Power / Propulsion
- Determine NiCd vs NiMh
- How many cells for 1.5 lbs
- How long will battery last at full power (20 amps)
- Feasibility of splitting into two packs for multiple engines
- Determine how we will mount engine onto trainer model
- Continuing testing of prop vs ducted fan
- Look into placing ducted fans in series (turbine)
- Airfoils / Airframes
- Look into building wind tunnel if we can't get access to Aero Dept
- Design testing rig for in the wind tunnel to gain lift and drag components from wing
- Test wings that we have built using whatever wind tunnel we get access to
- Get rockets for sizing and design consideration
- Complete optimization of scoring formula
- Analyze three designs for testing
- Finish the plane body for the trainer model
