Diagram of Saturn V instrument unit. The Saturn V instrument unit is a ring-shaped structure fitted to the top of the Saturn V rocket's third stage and the Saturn IB's second stage (also an S-IVB). It was immediately below the SLA (Spacecraft/Lunar Module Adapter) panels that contained the Apollo Lunar Module. The instrument unit contains the ...
The SLA was composed of four fixed 7-foot-tall (2.1 m) panels bolted to the Instrument Unit on top of the S-IVB stage, which were connected via hinges to four 21-foot-tall (6.4 m) panels which opened from the top similar to flower petals. The SLA was made from 1.7-inch-thick (43 mm) aluminum honeycomb material. [2]
The Saturn V broke the sound barrier at just over 1 minute at an altitude of between 3.45 and 4.6 miles (5.55 and 7.40 km). At this point, shock collars, or condensation clouds, would form around the bottom of the command module and around the top of the second stage.

As 19-inch equipment has a maximum width of 17 + 1 ⁄ 4 inches (438.15 mm), they can easily be mounted in an ETSI rack by means of an ETSI bracket or adapter plate. In contrast to the 19-inch standards, ETSI also defined the size of the rack enclosure: the four allowed widths are 150, 300, 600, 900 millimetres (5.9, 11.8, 23.6, 35.4 in) and ...
A height gauge is a measuring device used for determining the height of objects, and for marking of items to be worked on. These measuring tools are used in metalworking or metrology to either set or measure vertical distances; the pointer is sharpened to allow it to act as a scriber and assist in marking out work pieces. Devices similar in ...
