Purpose of Test

	Proof:
	— Overspeed - ensure rotor integrity by testing to a speed above operating speed
	— Pre-spin - test to a speed which induces plastic growth in the rotor bore and rim (also known as pre-stressing)
	Burst - determine component ultimate failure speed
	Containment - evaluate capability of containment structure to contain rotor burst
	Low Cycle Failure - establish rotor life by repeatedly cycling from idle to operational speeds
	Radial Growth Measurement - measure rotor growth, ID and OD, at speed
	Strain Measurement - measure rotor strain levels at speed
	Other - describe desired test
