We are an interdisciplinary capstone team at UC Santa Barbara, and our goal is to design, build, and fly an aircraft powered by ionic propulsion.
Ionic propulsion is silent and has no moving parts. A drone with ionic propulsion could be built with solar panels to achieve infinity flight. And, ionic propulsion is really cool!
Electrodes properly arranged and given thousands of volts will ionize and accelerate air molecules. Known as corona discharge, we can take advantage of this phenomenon to generate thrust. A power converter is used to step a 200V battery voltage up to the 40kV thruster drive voltage. The converter consists of an H-bridge, transformer, and Cockroft-Walton multiplier. Lithium-polymer cells are used as a lightweight power source.
Our second prototype airframe (currently being built), which we think can fly 1-2km in 4-8 minutes.
Oh, what a difference control surfaces can make.
Turns a 200Vdc input into 200Vac, 800Vac, 160000Vac, and finally a 40kVdc output. Imagine the electrons dancing inside! Like Oompa Loompas in a chocolate factory.
These batteries provide a total output voltage of 200V, which feeds into the power converter above.
As touched on in the "How does it work?" section, thrust is generated by electrode pairs. The electrode pairs here are a 0.1mm stainless steel wire my finger is touching, and a copper strip taped to a PVC pipe at the top of the frame.
Our first glimpse at flight.
Yes, we built a trebuchet.
