Latest Patents

Harper holds a patent for an Optical Flameout Detector. This device is designed to monitor the presence of a flame within a combustion chamber. The optical flameout detection system responds to significant changes in combustor light intensity, which is monitored in two spectral bands. A photomultiplier tube is utilized for optical measurements in the ultraviolet spectrum, while a silicon photodiode covers the visible region. The detectors are strategically placed outside the combustion chamber and receive light energy radiated from the combustion process through fiber optic probes. These probes are engineered to function in high-pressure environments. The optical fibers are aimed diagonally through the center of the injector at the combustion chamber wall downstream of the injector. This setup allows the system to quickly detect longitudinal movement of the flame front away from the injector. If a change in intensity of the flame is detected, the fuel supply to the combustion chamber is automatically shut off, thereby limiting the amount of unburned fuel that could reignite.
