To get things started, here is the first lesson I prepared for the Academy, following the lesson are the questions and the answers, please review and comment.
MAIN SKELETAL STRUCTURE
The primary spaceframe of the Galaxy class starship is fabricated from an interlocking series of tritanium/duranium macrofiliament truss frames. These members average 1.27 m2 in cross section, and are located an average of every 25 meters across the ships exterior.
Larger numbers of these trusses are located integral to the main and saucer impulse engine sections, the warp nacelle pylons, both saucer and battle sides of the docking latch interfaces, and along the centerlines of both hull structures. Smaller trusses, overhanging 0.53 m2 in cross section, are located every five meters on average, and also provide internal supports within the deck and core structure of the spacecraft interior.
This basic mechanical framework provides physical integrity to the vehicle while at rest. A parallel series of aluminum crystalfoam stringers are phase-transition bonded to the primary trusses, providing low-frequency vibration attenuation across the main truss structure, as well as support for certain utility conduits.
Also attached to these stringers are various conformal devices built into the hull structure, including elements of the deflector shield grid, as well as subspace radio antennas, which are incorporated into the exterior skin of the spacecraft.
SECONDARY FRAMEWORK
Mounted to the primary spaceframe is a secondary framework of microextruded terminium trusses to which the inner hull structure is directly attached. The secondary framework is mounted by means of 3.2 cm diameter x 5.1 cm log semirigid polyduranide support rods, permitting a limited amount of mechanical isolation from the primary spaceframe for purposes of strain relief, plus sound and vibration isolation. Secondary spaceframe segments are also separated from each other (although mechanically attached) to permit replacement of inner hull segments and associated utilities infrastructure during major starbase layover.
Structural integrity during powered flight is provided by a series of forcefields that reinforce the physical framework. This structural integrity field energy (SIF) is distributed through a network of molybdenum-jacketed waveguides, which in turn distribute SIF energy into ceramic-polymer conductive elements throughout the spaceframe. without the structural integrity field, the vehicle would be unable to withstand accelerations greater than 7.4 m/sec2 without significant deformation, or greater than 19.5 m/sec2 without unrecoverable structural damage (in other words, the spacecraft would sag under its own weight in Earths gravity without the reinforcement of the SIF [see chap 2.4]).
The exterior hull substrate in joined to the primary loadbearing trusses by means of 4.8 cm diameter electronbonded duranium pins at 1.25 meter intervals. These pins are slip-fitted into and insulating AGP ceramic fabric jacket that provides thermal insulation between the spaceframe and the exterior hull. The pins, jacketing, and hull segments are gamma-welded together.
