Wind Powered Water Pump
Developed a control system to connect to a kite flying in a figure-8 pattern. Control system converted kite motion into reciprocating motion which could then be easily used to pump water. Using wind speeds of 5.4 m/s the daily water needs could be pumped for 8000+ people as calculated using Matlab. Ansys was utilized to verify the parts would not experience stress in excess of yield strength.(Sep 2019 - May 2020)
1. Problem Statement
Constrained to a figure-8 flight path attached to a sliding track a control system needed to be designed to reliably pump water in a remote location.
2. Flight Simulation
SImulated the figure-8 kite path using Matlab. Determined max power output of 1.25 kW with a wind speed of 5.4 m/s. Provided water for 8000+ people's daily needs.
3. Control System
Slotted a pin into disc pairs connected to the kite tethers. Pins rolled in a 90° slot to permit travel along the length of the track. Pins then reversed direction of travel.
4. Failure Analysis
Performed stress analysis on all mechanical components. Max stress of 1.15 MPa on disc which was well within the 40 MPa yield strength of the uPVC Material chosen.
5. Machining
Using a lathe and mill (manual & CNC) the parts were machined within acceptable tolerance. They were then assembled according to the design.
6. Testing
A test flight was arranged in a field. Two operators are required to get the kite into stable flight. It was also determined that weights should be provided to anchor the system.
