专利汇可以提供Engine inlet distortion testing apparatus专利检索，专利查询，专利分析的服务。并且Apparatus is disclosed for testing the capability of a compressor or gas turbine engine to operate under conditions where the normal, generally uniform pressure distribution of the inlet is distorted by pressure gradients as may be encountered in aircraft maneuvers. Three discs are provided in a simulated engine inlet. All of the discs have equispaced, registerable apertures. The middle disc comprises inner and outer sectors which are angularly adjustable to control the extent to which their apertures are registered with the apertures of the immediately adjacent downstream disc and thus the degree and location of distortion. The upstream disc is rotatable to provide dynamic pressure distortion patterns. The upstream disc is adjustable toward and away from the other discs to vary the severity of the dynamic distortions.，下面是Engine inlet distortion testing apparatus专利的具体信息内容。

权利要求

1. Inlet distortion test apparatus comprising a simulated inlet for connection to the entrance of a compressor and including a fixed, apertured disc disposed in said inlet and a rotatable, apertured disc disposed in said inlet adjacent said fixed disc, said rotatable disc being capable of complete rotation with respect to said fixed disc, said rotatable disc further being capable of axial movement with respect to said fixed disc.

2. Inlet distortion test apparatus as in claim 1 wherein the apertures of the two discs are registerable and equiangularly spaced around the discs.

3. Inlet distortion test apparatus as in claim 1 further comprising a third disc having apertures registerable with the apertures of the other discs, said third disc being angularly adjustable relative to the fixed disc to control the degree of registration of the apertures thereof.

4. Inlet distorTion test apparatus as in claim 1 further including means for varying the axial spacing between the rotatable disc and the fixed disc.

5. Inlet distortion test apparatus comprising a simulated inlet for connection to the entrance of a compressor and including a fixed apertured disc disposed in said inlet, a rotatable, apertured disc disposed in said inlet adjacent said fixed disc, a third, apertured disc located adjacent said rotatable disc, the apertures of the three discs being registerable and equally angularly spaced around the disc with said third disc being angularly adjustable relative to the fixed disc to control the degree of registration of the apertures thereof, and said third disc comprising a plurality of inner and outer sectors which are individually adjustable in an angular sense relative to the fixed disc so that registration of the apertures thereof may be varied in an overall fashion or locally, as desired.

6. Inlet distortion test apparatus as in claim 5 wherein the rotatable disc is located upstream of the adjustable disc and the latter is upstream of the fixed disc and further including means for varying the axial spacing between said rotatable disc and said adjustable disc.

7. Inlet distortion test apparatus as in claim 6 wherein means are provided for varying the rotatable disc from a planar form to a conical form variably spacing its outer periphery from the adjustable disc.
