Airship, Variant (3.5e Equipment)
From D&D Wiki
ADOPTED PROJECT OF AEROS ANGEL ON 20130413
There are three categories: Small, Medium, and Large Airships
Merchant Troller Class Light Air Vessel Constructed of wood and few metal fittings used to base the more delicate materials together, a Merchant Troller is equipped for short hauls between regional ports and is not really designed for being skyward for extended periods of time. Often plain and lacking in creative design, one might say the creators literally took a Caravel from the sea and bid it fly. Whereas sea vessels are driven by wind power and sails, an airship of this type runs on a kerosene burning steam engine which drives a single prop set of fan blades directly aft of the ship. The ships rudders are mounted on either side of its propeller to provide better governing of its movements as well as give the prop minor coverage from damage. Rise and decent control of the vessel is achieved using a pair of prow mounted fins or "wings" which are controlled in unison on a pair of spring pulleys connected by strong guywires leading back to the ships conning point near the rear of the ship. These are connected to a pair of conjoined throttles which can be easily accessed by the helmsman during flight and while maneuvering through the delicate byways of an air dock to its moorings. To keep the ship afloat, animal hide balloons, all cured with a tallow or waxen coating to prevent escape of the gasses within are strung along the hull below the gunwale along both sides of the vessel, spanning from the prow back to amidships, then dropping another row all the way back until they reach 5' from the rudders. To counteract leveraged lift due to the steam engines weight variable in the rear compartment, a special tail scoop known as the "feather" is also filled with hide balloons to establish balanced lift along the craft as a whole. The Feather and all sections along the hull are overlaid by strong hemp netting which keeps the bags tight to the hull and prevents them from coming loose, becoming damaged by light contact, or dislodging and flying away. Some vessels owned by more profitable merchants may also then be overlaid with canvas to keep the regal and sleek appearance of a clean vessel, though it does little to gird up the ship in any way. Relative lift of such a craft is maintained by the gasses buoyancy. Thus anytime an airship comes to rest, it must be moored, aka tied, down to the docking station. Often times the railing of such vessels will sport pegs for bags of sand or rock to be placed in an effort to defeat the crafts normal lift and keep it steady at its mooring.
STATISTICS: Dimensions: 50'L X 15'W X 15'H Areas 12' Foredeck, 13' Aft deck, 25' Conning deck and control station (living and working quarters located beneath the conning deck.) Interior of the vessel is very simple, consisting of a long open bay where the crew and captain (between 6 and 8 persons) can sling hammocks or wall folding bunk racks on nicer ships. The captain’s bunk also includes a small chart table, cabinet, and a small wooden truck to store navigational supplies. A copper bill pipe also extends through the floor of the conning deck to the Captains area so as to transfer course changes and other orders on sheets of paper to the personnel manning the wheel. This pipe comes with a leather cap to prevent whistling whilst the crew slumbers.
At the front of the vessel is a simple wooden hatch, leading into the 12' x roughly 13' wide to the nose cargo chamber. Only a modest and small chamber, it is capable of moving up to 2000 lbs. of goods of appropriate size and measure as the cabin can hold at one time. Can also serve as the ships brig in times of need.
To the aft is another wooden hatch leading to the engine room. Inside sits a simple pressure driven steam engine heated by a pot belly kerosene oil Bunsen. This engine turns the drive shaft of the ships single propeller using a pair of thick leather drive belts. Max speed of this type of engine during good weather and fair winds is 15 KMPH. If pushed by a seasoned boiler mechanic at the captain’s request, the ship may reach speeds of 22 KMPH but runs the risk of overheating and taking the whole ship down in a pyre of flames. To mitigate this risk, barrels of water are kept in the engine hold along with the normal steam reserves and Oil vats to assist in cooling the engine down and prevent it, Steam Lords Willing, from sundering, seizing, and in turn detonating under the pressure. Pipes leading from the engine are vented out the back of the ship to allow excess pressure a chance to bleed off safely during normal operations.
The upper deck is walled with a 3' tall railing that creates the conning deck. A small stair set of either side of the stairs leading down into the hold grant access to this area. Located on the conning deck are the Steering Wheel, acceleration throttle, elevation throttles, a vox tube for speaking to those located below deck quickly, and a small trio of pressure gauges which allow the pilot to see the current engine readings, steam pressure, speed, and engine temperature. Likewise a second vox tube extends from this area for the ships pilot and engine mechanic to communicate directly during flight.
Mean Tare Weight: 5000lbs Mean Carry weight: 3200lbs (crew, cache, and cargo) Crew Limit: 5 Crewman, 1 Mechanic, 1 Helmsman/Pilot, and Captain. Fully Fueled Flight Time: (With reserves included) 9 hours, 14 hours if travelling light cargo at half speed. Average Mean speed: 15 KMPH (Roughly 135 miles one way trip) (Roughly 130 feet a round in combat) Push speed: 20-22 KMPH, Heat factor increased by 40% Normal heat generated by operating at mean speed 93* in engine housing. Volatile at 170* Lift Variable: Arrested at +150 lbs. ballast Structure points: 25 (Volatile at 8) AC: 16 Effective HP: 125 Armaments: none Armaments Capable: --- front quarter, mounted plug cannon, ram loaded. Small defensive cannon good for little more than winging raiders and forcing them to wave off. Rear quarter, Mounted plug cannon, ram loaded, or Small grapeshot cannon meant to disable foe vessels ballasts or steering capability.
Mounted Plug Cannon: 2d12 damage requires full round action by two PC's to reload. Fires a fist sized ball shot at its target; ball is made of iron or comparable metal and filled with an explosive substance. Requires DC 15 reflex save to fire effectively. Uses the firing PC's ranged attack BAB or BAB +4, whichever is lower. Range 75-100 feet.
Small Grapeshot Cannon: 3d8 damage (15 foot spread shot out to 50 feet). Requires full round action by two PC's to reload. Fires a wad of inch wide iron ball shot meant to pepper the target and possibly puncture its ballasts or rake the deck and injure the opposing crew. Severely effective at close range. Requires a DC 15 reflex save to fire effectively. Uses the PC's ranged attack BAB or BAB +3, whichever is lower.
Average cost, un-crewed, unmodified, unarmed (with boiler engine installed) 22000gp. Roughly 17000gp without the engine. Written by AEROS ANGEL
