Book Description
A full-scale annular combustor was operated with simplex fuel nozzles of three flow ranges and with dual-orifice fuel nozzles. The dual-orifice nozzles provided combustion efficiencies within 2 to 3 percent of the peak values obtained with any of the simplex atomizers. A wide range of operating conditions including altitude relight, simulated takeoff, Mach 2.7 cruise, and Mach 3.0 cruise were studied. Measurements were made of combustion efficiency, pattern factor , flame radiation, smoke emission, and response to rapid increase in fuel flow. Fuel heated to 300 [degree] F (423 K) was used in many of the tests; heated fuel usually increased combustion efficiency.
