The Feasibility of Detecting a Burner-Can Burn-Through by Means of CO, CO2,Pressure,and Air Temperature Levels in a Jet Engine Nacelle.

摘要

Full-scale tests simulating engine combustion section thermal failure (burn-through) were conducted using a cowled J-57engine to determine the feasibility of detecting a burn-through by monitoring the carbon monoxide (CO),carbon dioxide (CO2), a pressure level,or air temperature in the nacelle before,during,and after engine case rupture. Results of the tests indicated that CO, CO2,pressure,and air temperature in the nacelle cannot be relied upon for early detection of a burn-through. Test results also indicated that containment of a burn-through flame in the nacelle creates extremely high temperatures in the nacelle and can cause extensive structural damage. (Author)
