Next Challenge: How do you think about the technological safety needs of children and other dependents? |
Our gas-powered turbine engines require heat, fuel, and oxygen, like all combustion engines. The “heat” aspect comes in the form of ignitors, which essentially “spark” or start a fire within the fuel and oxygen mix, causing an explosion within the chamber.
Currently, our ignition system consists of a spring-loaded igniter assembly. As combustor shell air pressure overcomes spring force, the igniter retracts out of the flame zone. One version of an ignitor consists of a single piece igniter, high tension exciter (~25kV), and igniter cables with a Teflon insulator. Some combustors have one ignitor in each basket, whereas others only have two baskets with ignition points that carry the flame 360° around.
We want your help finding a completely new way to introduce heat and a spark to start the combustion process of the fuel-and-oxygen mix.
To better understand the concept, please see these videos:
Explain your redesign of our combustion engine ignition process. Specifically:
- Submit a visual that illustrates your idea, demonstrating how ignition is changed from the current method and design. Your visuals should be original, not something found online. CAD renderings or other high-quality formats are preferred.
- Explain your idea. What materials are used, how does it function, and what benefits does it offer?
NOTE: If you attach your submission as a PDF, PPT, Word Doc, or other file type, you must still paste your answer text into the body of the submission window. Failure to do so will result in a lower score.
Answers must be submitted in English.

Submissions will be graded on the following criteria:
- Quality of Visual
