Experimental Investigation of Factors Influencing Operating Rotor Tip Clearance in Multistage Compressors

Table 1

Rotor blade aspect ratios and clearance-to-chord values.

	Rotor 1	Rotor 2	Rotor 3
Blade aspect ratio	0.76	0.72	0.68
Clearance-to-chord value (1.5% span)	1.14%	1.08%	1.02%
Clearance-to-chord value (3.0% span)	2.28%	2.16%	2.04%
