Step
If using LCTs ensure they are properly attached per section 18.2 then proceed
8.1.9
to section 18.3.
Compress the Lightband. This can be achieved by placing weights on the
8.1.10
Upper Ring, using the weight of the payload, compressing in a fixture, etc. The
total applied force shall be within the range calculated below.
Separation Spring quantity = ________
Minimum force = ____Springs x 20 lb = _____lb
Maximum force = ____Springs x 30 lb = _____lb
Apply the force gradually and verify all Hinged Leaves rotate inside the Upper
Ring as it compresses.
Stop once the minimum force is applied.
Once the minimum force has been applied to the Lightband, verify that the
8.1.11
Lightband is properly compressed. Figure 8-5 shows a cross section of the
stowed Lightband. Verify the pre-stow height (distance between flanges) in at
least 4 locations complies with the figure. If any measurement is not within
specification verify proper alignment and compressive force. Increase force as
necessary, up to the maximum allowable per Step 8.1.10, until the Lightband is
properly compressed.
