摘要： 通过实验与理论计算两种方法对旋流加力室火焰前锋位置作了探讨性研究。对叶片可调的旋流加力室模型在其叶片角为２５°、３０°时旋流器后的温度场进行了实验测量，从而定性地标定了火焰前锋的位置；理论研究时利用了＂焰泡＂理论，对叶片旋角分别为１０°、２０°、２５°、３０°、４０°时火焰长度进行了计算。最后将两种方法所得结果作了比较，结果表明两者基本相符，且均小于传统的火焰长度。

Abstract: oth experimental and theoretical investigations are presented on the flame length in swirling afterburner with adjustable vanes. In the test, the flame length was approximately obtained by measuring the temperature field at the exit of burner with swirl angle of 25° and 30°." Flame bubble" theory has been applied to predict the flame length with swirl angle of 10°、20°、25°、30°、40°. The prediction and expermeent show good agreement over the range of conditions.
