Title: Innovations by Frederick B Sontag
Introduction
Frederick B Sontag is an accomplished inventor based in Jacksonville, FL. He holds 2 patents that showcase his expertise in ignition systems for turbine engines. His innovative designs have contributed significantly to advancements in this field.
Latest Patents
Sontag's latest patents include an "Ignition System for a Turbine Engine" and an "Apparatus and Method for Providing Ignition to a Turbine Engine." Both inventions utilize a unipolar ignition system that provides a current waveform at the ignitor plug. This waveform initially rises slowly, transitioning to a fast-rising current that peaks and then dissipates slowly. This design results in a hotter and longer-lasting spark, which does not harm the ignitor plug or shorten its life expectancy. The system also avoids creating stress on the solid-state circuitry that delivers energy to the ignitor plug. An inductor with a saturable core is used in series with the ignitor plug, allowing for a controlled rise in current that is essential for effective ignition.
