The section provides hard points for the attachment of structural modules for the OAMS tanks, Environmental Control System primary oxygen supply, fuel cell (batteries on spacecraft 6), coolant, electrical and electronic components, Extra Vehicular Activity (EVA) equipment on spacecraft 9 through 12, and Rendezvous Evaluation Pod on spacecraft 5 only. A gold deposited fiberglass temperature control cover protects the equipment from solar radiation through the open end of the adapter after separation from the launch vehicle. The equipment section is the larger diameter end of the adapter. The device is attached to the large diameter end of the cabin structure by 1/4 inch bolts. Ten OAMS thrust chamber assemblies are mounted on the large diameter end of the equipment section. Two large structural hatches are incorporated for sealing the cabin ingress or egress openings. An external hatch linkage fitting is incorporated to allow a recovery hatch handle to be inserted for opening the hatches from the outside. The voltage and ground of an IC should be connected directly to the sources (no resistance between); resistors built into the IC will handle how the current is supplied to the IC. These algorithms seek to determine the control parameters that will minimize the residual distortion.Utilizing an adaptive feed-forward system enables us to achieve lower distortion levels lower than would otherwise be possible.
Parameters are obtained from the ignition command of the four retrorockets individually; ADO9, rocket 2; ADO8; rocket 3; ADIO, rocket 4. The manual and automatic retrofire commands indicate retrorocket I fire. When initiated, the actuators simultaneously unlock and open the mechanical latches, open the hatches and supply hot gases to ignite the ejection seat rocket catapults. Each of the ingress/egress hatches incorporates a visual observation window. Each window consists of an inner and outer glass assembly. The panes in the right window are optically ground for better resolution. The panes consist of Vycor (96% silica). The outer assembly is a single flat pane and the inner panel assembly consists of two flat panes. On the bottom of the cabin, between the landing gear doors, two additional doors are installed. The landing gear is not installed but fittings are provided for the attachment of the gear for future spacecraft. After water landing, when the hatches are open, the curtains are installed to help prevent water from entering the cabin. The hatches are symmetrically spaced on the top side of the cabin section. In an emergency, the hatches are opened in a three sequence operation employing pyrotechnic actuators.
The forward end of the adapter is coupled to the aft end of the re-entry module by utilizing three titanium tension straps. The shield is designed to protect the re-entry module from extreme thermal conditions during re-entry into the atmosphere. The shingles are black on the outer surface to control thermal radiation. The external surface of the cabin is made up of beaded shingles of Rene' 41. The R and R and RCS section surfaces are made up of unbeaded shingles of beryllium. The inner surface of the beryllium shingles are coated with gold to provide a low emissivity surface. The shingles protect the re-entry module structure from excessive heat and provide additional rigidity for the cabin. The O2 CROSS FEED coaxial switch, spacecraft 6, 8 and 9 when in the OPEN position, permits oxygen from the primary oxygen supply module for the ECS to be used in the RSS in the event of RSS oxygen module failure. If your SSR module is similar to the one that I used then you should see the LED indicators on the module chase as well. In the event of both pumps failing in one circuit, both pumps of the remaining circuit can be used to provide the required cooling.
The I beams are assembled in the form of a cruciform with one retrograde rocket mounted in each quadrant. A honeycomb blast shield is provided above the modules to shield the equipment section and booster dome from excessive heat during retrograde rocket firing under abort conditions. The forward door allows access to the lower equipment compartment and the aft door provides access to the Environmental Control System compartment which is a portion of the pressure vessel. Each surface of each pane, with the exception of the outer surface of the outer pane, is coated to lessen reflection and glare from cabin lights and to aid in impeding ultraviolet radiation into the cabin compartment. The outer surface of the skin is coated with white ceramic type paint and the inner surface is covered with aluminum foil. The adapter is a truncated cone-shape, semimonocoque structure consisting of circmuferential aluminum rings, extruded magnesium alloy stringers, and magnesium skin. The spacecraft is mated to the Titan II Launch Vehicle with a machined aluminum alloy ring.
