Embodiment 1
[0024] This embodiment is a compressor stator blade with suction surface suction, which is used for boundary layer suction and testing on the 0-50% span area of the suction surface of the compressor stator blade.
[0025] Such as figure 1 As shown, a stator blade of a suction side suction compressor proposed in this embodiment includes a blade body 5 and a blade shroud 1 . There is a fixed pin 8 at the blade tip. There are 35 suction holes 7 and 7 static pressure holes 6 distributed on the suction surface of the blade body 5 .
[0026] The suction holes 7 are divided into 7 rows, uniformly arranged from the leading edge to the trailing edge of the blade body 5, and the distance between the center of the first row of suction holes 7 and the leading edge of the blade is 12% of the chord length, the seventh The distance between the center of the row of suction holes 7 and the trailing edge of the blade is 28% of the chord length; the distance between the first row of suction ...

[0035] This embodiment is a compressor stator blade with suction surface suction, which is used to perform boundary layer suction and test on the 45-100% blade span area of the suction surface of the compressor stator blade.
[0036] Such as figure 1 As shown, a stator blade of a suction side suction compressor proposed in this embodiment includes a blade body 5 and a blade shroud 1 . There is a fixed pin 8 at the blade tip. There are 25 suction holes 7 and 5 static pressure holes 6 distributed on the suction surface of the blade body 5 .
[0037] The suction holes 7 are divided into 5 rows, which are uniformly arranged from the leading edge to the trailing edge of the blade body 5, and the distance between the center of the first row of suction holes 7 and the leading edge of the blade is 50% of the chord length, the fifth The distance between the center of the row of suction holes 7 and the trailing edge of the blade is 10% of the chord length; the distance between the f...
Embodiment 3
[0046] This embodiment is a compressor stator blade with suction surface suction, which is used to perform boundary layer suction and test on the 20-80% span area of the suction surface of the compressor stator blade.
[0047] Such as figure 1 As shown, a stator blade of a suction side suction compressor proposed in this embodiment includes a blade body 5 and a blade shroud 1 . There is a fixed pin 8 at the blade tip. There are 90 suction holes 7 and 9 static pressure holes 6 distributed on the suction surface of the blade body 5 .
[0048] The suction holes 7 are divided into 9 rows, 10 in each row, evenly arranged from the leading edge to the trailing edge of the blade body 5, and the distance between the center of the first row of suction holes 7 and the leading edge of the blade is 10%. Chord length, the distance between the center of the ninth row of suction holes 7 and the trailing edge of the blade is 15% of the chord length; the distance between the first row of su...
