Latest Patents

One of his latest patents is a method and device for modulation of a flame. This invention pertains to air-breathing engines, such as ramjets, scramjets, and internal combustion engines. It focuses on an active combustion control device for a combustor. The invention applies active combustion control technology to advanced propulsion devices and utilizes closed-loop fuel injection at sub-harmonic frequencies of the instability frequency of the combustor. The challenge of limited actuator frequency response is addressed by injecting fuel pulses at these sub-harmonic frequencies. The fuel can be in liquid, solid, or gas form. To achieve the desired results, a closed-loop controller is designed to determine sub-harmonic frequencies using a divider to yield a fraction of the harmonic frequency. Additionally, this invention combines open-loop injection control with closed-loop injection control to enhance engine performance, including the extension of the stable combustion zone.
