The Crossroads of the Aether
An antipodean airship that is to be navigated throughout Aotearoa / New Zealand, plotting new topographical charts and establishing trigonometry stations on the way, whilst warding off pirates, sky krakens (ranginui taniwha), and picking up side jobs along the way, including urgent diplomatic missions, trade negotiations, and the odd moonshine run.
The Dirigible, Airship Halberg (ZE-138)
The vessel was built and is owned by Sir Tory Eversham, president of the Eversham Airship Company, of Portsmouth, England. Her boilerplate lists her home port as Portsmouth, England. She is a Drakkar-class airship.
Propulsion
Powered primarily by twin 330MW aft-mounted lateral outboard steam turbines, she also has two 185MW steam turbines mounted amidships that are gimbal-mounted and can rotate 270° through two planes, providing additional lift when needed, or additional trim during high winds. A further two 170MW steam turbines are located on the mast, which have a single plane gimbal and provide primary trim, keeping the vessel on an even keel at all times. The airship cruises at 50mph, and has a maximum speed of 70mph.
Lift
Other than the midships-mounted steam engines, the vessel maintains buoyancy through expeditious use of construction materials. The framework of the vessel is all tubular throughout, with each section being fully airtight and filled with lighter-than-air hydrium, a newly discovered gas which produces upwards of 5oz of lifting force per cubic foot! (Helium only gives just over 1oz of lift per cubic foot at sea level. Hydrogen is even less). The tubular framework of the vessel is fed hydrium through a lattice of thin copper pipes that can be used to feed or bleed hydrium to or from a particular section of the ship, providing buoyancy as and where needed. This is a closed system, with pressurized cannisters of the non-flammable hydrium gas located throughout the airship, so venting the gas to the atmosphere and replenishing hydrium stocks is not necessary. Unladen, the vessel can maintain buoyancy consistently at any altitude, and has an non-powered climb rate of 500 feet per minute, which can be increased to close to 600 feet per minute with the use of the midships steam turbines. The sink rate is equivalent to the climb rate, as the midships steam turbines can be rotated to provide downwards propulsion.

The Mission of the Airship Halberg
Our mission, as conferred by Her Majesty, in consultation with both the Governor of the colonists, and with the Rangatira of the United Tribes of Aotearoa (UToA), is to thoroughly travel the length and breadth of the antipodean islands of Aotearoa / New Zealand, plotting new topographical charts and establishing trigonometry stations at vantage points along the way that are not of cultural significance to iwi, but that can serve as fixed triangulation points.
The Crew of the Airship Halberg
* MASTER * (Payer of the bills and salaries)
The airship is on permanent loan to Sir Tory's nephew, Sir Ernest Roebuck III, KCB, FRGS, whom you may know of as Augur, the current Surveyor-General of Aotearoa / New Zealand.
* CAPTAIN * (Pilots the vessel)
Position currently vacant.
* ENGINEER * (Keeps us aloft)
Position currently vacant.
* NAVIGATOR * (Knows where we are heading)
Although Augur is the master of the airship, he is a gentleman of science, a cartographer and geographer, and not a qualified airship captain. He is, however, suitably qualified as a navigator.
* KAIARAHI TIKANGA MAORI * (Keeps us from foundering on the rocks of cultural ignorance)
Position currently vacant.
* METEOROLOGIST * (Knows where we will go)
Position currently vacant.
* COMMUNICATIONS OFFICER * (Keeps us up-to-date)
Position currently vacant.
* MECHANIC * (Fixes things that break down)
Position currently vacant.
* COOK * (Keeps us alive)
Position currently vacant.
* PHYSICIAN * (Keeps us alive after the cook's ministrations)
Lady Emma Darry
* LABOURERS * (Help out where needed)
All positions currently vacant.
For recruiting details, please see this letter, sent to the League of Airship Captains.

Permalink Reply by Augur on June 22, 2011 at 2:26am To be moving that fast, she must have a massive steam engine and boiler for propulsion. And to lift all that weight of the engine alone there must be a huge inflated superstructure. The Halberg is clearly going to be a mighty airship, probably one of the biggest in the antipodes. Uncle Tory never does things by halves! I just hope that she will be able to descend sufficiently to lower our crew and equipment whenever we need to build a trig station.

Permalink Reply by Augur on June 24, 2011 at 5:55pm I have received a surface-mail letter from my uncle Tory, containing the details of the Airship Halberg! She looks like a magnificent vessel indeed! Clearly, the reason that uncle Tory wasn't responding to my prior telegrams asking for details is that he had already posted them to me. It was definitely worth the wait.
