摘要： An apparatus and method for testing the flow distribution through a turbine engine fuel manifold and one or more nozzles connected to the manifold. A plurality of individual fluid measurement vessels, at least one for each of the nozzles being tested, collects test fluid pumped through the manifold and the connected nozzles. The level in each of the measurement vessels is periodically sampled during the test. The test fluid flow rate through each of the nozzles is periodically determined based on the periodically sampled levels.

摘要翻译： 一种用于测试通过涡轮发动机燃料歧管和连接到歧管的一个或多个喷嘴的流量分布的装置和方法。 多个单独的流体测量容器，对于被测试的每个喷嘴中的至少一个，收集通过歧管泵送的测试流体和连接的喷嘴。 在测试期间，每个测量容器中的水平均定期采样。 通过每个喷嘴的测试流体流速基于周期性采样水平周期性地确定。
