SAUCER MODULE SEPARATION SYSTEMS
The USS Enterprise consists of two spacecraft systems integrated to
form a single functional vessel. Under specific emergency conditions, the
two vehicle elements may perform a separation maneuver and continue
independent operation. The two elements, the Saucer Module and the Battle
Section, are normally joined together by a series of structural docking
latches, numerous umbilicals, and turbolift pass-throughs.
Eighteen docking latches provide the necessary physical
connections between the major load-bearing members of both vehicles. The
active side of the latches is located on the dorsal surface of the Battle
Section around the periphery of the Battle Bridge and upper sensor arrays.
The passive apertures for the latches are set into the aft ventral surface of
the Saucer Module. Each active latch segment consists of two spreading
grab plates driven by four redundant sets of electrofluidic pistons. The grab
plates measure 6.9 x 7.2 m and are constructed of diffusion-bonded tritanium
carbide, similar to the main load-bearing spaceframe members. These are
designed to accept and transfer energy from the structural integrity field
generators, locking the two vehicles together. The dorsal surfaces of the
grab plates are layered with standard ablative hull coatings for exposure to
the general space environment and warp flight stresses. The latching system
has been designed to accept a failure rate of 1.5 latch pairs per ten
separations; in the event a single pair fails to seat properly within its passive
aperture, the structural loads can be shared adequately among the other
latches.
Each electrofluidic piston consists of a main fluid reservoir, magnetic
valve controller block, piston computer controller, attach brackets, pressure
manifolds, and redundant sensor assemblies. Piston operation is maintained
under computer control to assure smooth activation of all latches
simultaneously, though under emergency conditions a manual latching
option is available.
Quick-disconnect umbilicals set into the vehicle interface, which
normally allow for the unbroken flow of gases, liquids, waveguide energy,
computer information, and other data channels, are isolated once the
separation sequence is commanded.
The vehicle interface also accommodates a set of standard turbolift
pass-throughs, including the dedicated emergency turbo to the Battle
Bridge. These shafts are equipped with automatic path termination seals,
which have been designed to double as airlock modules. If either separated
vehicle docks at another Starfleet facility at the vehicle interface, the
termination seals retreat to their default positions just off the turbolift shafts.
