Abstract
A structure of a 50 pound thrust level gas turbine jet engine combustor is a small type 50 pound gas turbine jet engine combustor. The combustor includes a combustor outer liner, a combustor inner liner and a hub. Pressure swirl fuel atomizer and thin film cooling devices are further used. In the combustor, a primary jet flow is matched with a jet tube so as to build a stable recirculation in the primary zone. 12 SIMPLEX fuel atomizers are installed in the inner liner for jetting fuel radially. The fuel must be jetted properly, if it is too close the front plate, the droplet will impact the front plate, then the downstream will possible destroy the recirculation structure. Therefore, if the fuel is jetted in proper positions, then the retaining time of fuel will be reduced greatly and the burning in the primary zone can be enhances. By analyzing and testing, it is appreciated that high temperature will induce at the middle section near the wall of the inner liner. Thus, a one way thin film cooling means and a bidirection thin film cooling means are designed for protecting the liner.
