| 摘 要： | 本文介绍一种涡轮风扇发动机加力燃烧室引燃式组合火焰稳定器的设计与试验研究。带波纹槽的吸入式主稳定器和辐射状带吸入孔的径向稳定器构成了这种引燃式组合稳定器。二元和两股流缩尺水流模拟试验显示了这种稳定器后方的气流结构,说明它能起引燃作用,并使内涵火焰强有力地支援外涵火焰。

| Abstract: | The design and experimental study of a combined pilot flameholder is presented for a turbofan engine afterburner with an annular mixer.The combined pilot flameholder is composed of a main ingestion gutter ring with corrugated slots and radial finger gutters with ingestion holes.The two dimensional and double stream flow visualization tests of its reduced scale model demonstrate the flow pattern hehind the flameholder,and also reveal the reason,why the annular pilot burner can ignite and support the bypass flow flame.Its sector rig tests and engine bed tests show that the afferburners with this kind of flameholder possess enhaneed combustion efficiency,improved combustion stability and reduced pressure loss at both normal and low pressures. |
