    摘要： The fire resistance of components normally subject to a standard flame test is evaluated using low temperature model tests. Reynolds number, Froude number, the pressure ratio of the flame to the surrounding atmosphere are matched in the modelling parameters and account is taken of the Prandtl number. Also, the model flow is controlled so as to match the change of momentum flux ratio in the flow through the burner used in a standard flame test. The method allows testing of easily produced model components at temperatures less than 90°C, with savings of cost and time.

    摘要： There is disclosed an impingement cooling arrangement for a gas turbine engine (6), and an engine provided with such an arrangement. The cooling arrangement comprises at least part of a casing (21) configured to define a flowpath for the passage of hot gases through the engine, and a manifold (22) configured to direct cooling air against an outer surface (23) of the casing for impingement cooling thereof. The arrangement is characterised by said manifold (22) being configured to direct a primary flow of cooling air (65) against a first area (64) of the casing outer surface (23) for impingement cooling of said first area, and to recirculate (66) at least a portion of said primary flow of cooling air after impingement against said first area (64) and to direct at least a portion of the recirculated flow against a second area (67) of the casing outer surface (23) for impingement cooling of said second area (67). In a preferred arrangement, the manifold (22) is spaced from said casing (21) so as to define a space (41) between the manifold and the outer surface (23) of the casing, and the manifold (22) further comprises a baffle (46) extending at least partially across said space, substantially towards said casing (21), so as to at least partially divide said space (41) into a first region (58) adjacent said first area (64), and a second region (59) adjacent said second area (67).

    摘要翻译： 通常使用低温模型试验来评估通常进行标准火焰试验的部件的耐火性。 雷诺数，弗劳德数，火焰与周围大气的压力比在建模参数中匹配，并考虑了普朗特数。 此外，模型流量被控制以便匹配在通过标准火焰测试中使用的燃烧器的流动中的动量通量比的变化。 该方法允许在低于90℃的温度下测试易于生产的模型组件，节省成本和时间。
