Spacecraft Spin Test Facility

Metadata Updated: March 8, 2017

FUNCTION: Provides the capability to correct unbalances of spacecraft by using dynamic measurement techniques and static/coupled measurements to provide products of inertia. Moments of inertia (MOI) can be determined on MOI tables of various capacities.DESCRIPTION: The facility contains two spin balancing machines (one horizontal and one vertical) to handle various types of balancing requirements. Both machines are provided with a plane separation network to obtain correction readings directly in the plane of correction. The spin machines require 100 ft 2 of space and are clamped to a slotted 4-ft-thick reinforced concrete floor for stability. Each machine has a remote control console to operatefrom a distance of 100 ft during hazardous operations. Various capacity MOI tables are used to verify MOI and center of gravity for units under test.INSTRUMENTATION: The vertical spin machine is a Schenk/Trebel model E-6 hydrostatic bearing spin table, has a load capacity up to 18,000 lb, spins at rates of 30 to 300 rpm, and is capable of 2 oz/in. accuracy. The horizontal spin machine is a Schenk/Trebel model FH600 horizontal hard bearing spin table with a capacity of 13 to 1300 lb, spin rates of 50 to 600 rpm, and 100 moz/in. accuracy. MOI tables include Space Electronics models GB8000 (capacity 8,000 lb) and 973-3000 (capacity 3,000 lb). Both have an accuracy of [HTML_REMOVED]0.5% of total MOI. Other MOI tables are ID models with 5-, 50-, 100-, and 200-lb capacities, and an accuracy of [HTML_REMOVED]0.005% of total MOI.
