Compressed air?


That works, although I'm pretty sure that the steam would do the compressing.


There's nothing at all preventing the blowers being powered directly by the engines, which is still powered by steam.

A little geared power takeoff with a long drive shaft off to the fans, rather like a supercharger. Or belt drives. Belts are traditional for aspiration. All the fans need is sheet metal and bearings. If they can't make bearings, the steam engine won't work at all, so I'm pretty sure they're OK for the necessary bits there.

Why would we believe that they were powered by anything other than steam? Turbines perhaps rather than piston stroke engines...but steam.

Or the traditional line shafting from the main engines (way more efficient than air power). You then have couplings to the fans.

To be sure it could be done that way but piping for air or steam makes for a safer work environment than shafts, pulleys and belts. And for a comaratively small craft facing combat situations, that's important.

Steam powered ships require two sets of blowers, one to provide air for the boilers and another to supply ventilation to the engine spaces. Powering the blowers with hydrolic fluid would be a fire hazard if hit with a shell.

For what reason? Even the KH is greatly overpowered, and would meet virtually no real opponents for at least fifteen or twenty years (well, unless the continentals wouldn't be able to obtain their own <s>Mary Sue</s> seijin. ;) ) For what reason Charis may need to spend money on even more overpowered warships?

That would, of course, depend on what you use for hydraulic fluid and where you route the tubing.

FWIW, water is an excellent hydraulic fluid for most applications. It's only real problem is it's low boiling point.

Answers! I got lots of answers!

How much they could make engine smaller without losing great amount of power? If by a lot, than we should be able to put another one and we would have something like 50% increase in output and in fuel usage.

Is there "Textev" that the boilers are forced or induced draught?
I've overlooked it if there is, or is the draught solely due to the "tall, slim funnels"

The fact that sparks are discharged as a result of firing (as mentioned during the canal raid) suggests that forced/induced draught is in use but otherwise I have found no mention.

Why a KGV?, not a very good design IMNVHO as the design was constrained by the (useless ?) Washington and London Treaties. (As also the two "Cherry Trees")

Surely a better design would be the "Queen Elizabeth" or "Vanguard" if using RN practice as your guide.

The Imperial Russian "Gangut" and"Imperatritsa Maria" Classes had some novel and potentially useful attributes as well for first generation dreadnaughts.

I agree that there is not much point in developing large warship design for the EOC further as long as there are no peers for the ICN on the horizon.

But it probably would make sense to develop a fleet of cruiser sized vessels for response and power projection purposes along with whatever the required coaling stations to fuel the fleet.
