The detection method generally comprises the steps of measuring the infrared emission characteristics of a jet engine exhaust and generating a detection signal when the intensity of infrared emissions at or near a spectral peak wavelength exceeds a threshold."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Detecting volcanic ash in jet engine exhaust","description":"Onboard systems and methods for early detection that an aircraft has flown into a volcanic ash plume embedded within a water vapor cloud having a concentration of a volcanic ash which would be dangero","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8461531","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
