Detailed Design Review Group P16228: Mike, Zach, Joe, Elijah & Bernie

Team Vision Bernie: Enclosure designs, SolidWorks drawings/sheets, calculations of rotational velocity, and several efficiencies, PCB drawing on SolidWorks, attempted Flow Simulation (propeller would not rotate so it was unsuccessful), worked on Test Plans, initial test conditions/boundaries & predicted results Elijah: Solenoid controller/power board revision, power supply selection, electrical component testing procedures Zach: Design changes/improvements, SolidWorks parts+assembly, preliminary levitation test plan Joe: Manage expenditures/maintain budget, Update BOM, Preliminary coding (Matlab or Python) Mike: Axially magnetic stability physical design revision, high-level code flowchart, BeagleBone-MATLAB interaction research, preliminary solenoid development

SolidWorks Assembly (Rear Cutaway)

Initial Conditions/Predicted Test Results Test to be performed in air Wind speed variable (for this case 5 m/s) Density of air: kg/m^3 Motor/Propeller RPM: 842 Rotational velocity: 5.47 m/s Mass flow rate dependent on wind speed or exit speed (for this case kg/s) Exit velocity of the air dependent on wind speed (for this case m/s) Expected thrust of the propeller with these conditions: 0.88 N The expected outcomes are much different if tested in water

Axial Stability Component Placement Concept (Revised)

High-Level Code Design

Schematic (Solenoid Controller)

Outputs and Power indicators (LEDs)

Controller (specific circuitry)

Current Board Fixes ◦Should add debouncing caps ◦Should move diodes and increase size Order the plain version as it works Create a better board to be ordered and used later

Current Board Dimensions: 2.19” x 3.38” ◦56mm x 86 mm Price: $36.90 for three boards

Bill of Materials (BOM) Motor Construction Purchase motor $914 New Budget $4,000 for “allowed” spending $1, allocated Funds spent to date: $128.99

Test Plans (Overview) Magnets: Stabilization (lateral, axial) Mock build Propeller: Flow simulation Motor: Use encoder to measure RPM; hook up and see if it spins Solenoids: Helmholtz coils Enclosure: Leaking & see if the motor fits Coding: Check values, troubleshoot, and emulate Temperature: thermo-coupling Solenoid Controller: verifying proper voltage output via multimeter, based on different inputs Power Supply: verifying the proper voltage is being output
