METHOD AND APPARATUS FOR IGNITION DETECTION

摘要

Methods and apparatus of detecting rocket engine (72) ignition comprising a camera assembly (62) connected via fiber optic cables (64A and 64B) to hot ends (69A and 69B) to detect electromagnetic spectra, and a control assembly (65 and 76) operatively interconnected with the camera assembly (62) to monitor and evaluate the spectral data collected by the camera assembly. The control assembly is generally programmed with first and second predetermined thresholds associated with respective first and second electromagnetic spectra, and a time threshold at least generally associate with a first time parameter in which at least one of the first and second predetermined thresholds should be reached.
