Är det några "Springsharp" frälsta här? För den som inte vet vad programmet går ut på så är det ett beräkningsprogram för först och främnst beräkna slagskepp-jagare mellan 1850-1950. Ämnet har varit uppe tidigare på skalman.

Varifrån kommer bilderna (på kustflottan-länken), är de självmeckade eller genererade ur programmet (kanske inte så troligt)? Har lite svårt att utläsa informationen ur de tabeller ni visar, landkrabba som man är, ungefär som att läsa ett dimensions-diagram över Victoria Silvstedt... ;)

 

Och var är HMS Gotland CVN-1? :happy:

Bilderna på "Kustflottan" är gjorda med ms Paint och förfinade i GIMP eller MGI Photosuite. Skalan är 1m = 3pixlar.

 

@HMS Karlstad, herrejistanes, det där är fysiskt omöjligt, hon är helt omrimilg både på längden och bredden, vad vill du ha, storlek eller bestyckning. Konstruktion saknar helt verklighetsförankring, programmet är verklighetsbaserat på statistik från ett strt antal riktiga fartyg.

varför "Deckmounts" på huvudartilleriet och dessa i två poster utspridda längs midskeppslinjen? du har ytterliggare 1,45 HS att fördela ut, din konstruktion är stor som ett slagskepp men har en förmåga som en gammal pansarkyssare.

 

Din konstruktion borde ligga runt 10000ton, dessutom så saknar den nästan helt sjövärdighet (0,37)

Din "Karlstad" har en rad problem.'

 

1. Dimensionerna: Hon har helt oproportioneliga dimensioner. 1:20 är alldeles för smalt, och 10m djupgånende för mycket, ett slagskepp som Bismarck ligger på ca 8-10m, ett fartyg på ca 120m på har ett djupgående på 4-6m. Läng:bredd förhållandet bör ligga runt 1:10-1:15 för en jagare (dvs 120x12-16m) och en bit mer för ett slagskepp. Sverige var 120m lång, 22m bred och stack ca 6m. Blockkoeficeienten beskriver hur fylligt skrovet är.

 

2. Farten, 45knop är alldeles för mycket för en så tungt lastad båt. Hästkrafterna och maskineriet springer iväg närskrovet börjar plana (ju längeskrov, ju högre fart utan att plana). Ett 120m skrov på en jagare blir max 35-40, men då med väldigt lätt bestyckning

 

3. Bestyckningen, du har slagskeppsbestyckning på ett skrov som knappt är dimensionerat till en jagare- lätt kryssare. Pansaret är samma problem, du borde ha ett bälte som för ett slagskepp motsvarar huvudkalibern i tjocklek. Kryssare kanske något mer än hälften och en jagare bara lätt splitter skydd. Sekundärpansaret på fartyg efter 1920 bara splitterskydd, precis som tprn och hissar.

 

4. Välj lavettyp, "deckmount" är ett lavett som bara är förankrat i däcket och bara enkel sköld som skydd, "Mount and hoist" ett "torn" med hissar men utan barbette. "Turret and Barbette" ett vanligt slagskepps eller kryssartorn, "Coles-Ericson turret" en äldre typ av torn som de som satt på USS Monitor. "Casemat" pjäserna uppställda i kasematter dvs pansarrum längs fartygssidan till skillnad från "broadside mount" som är ett klassiskt batteridäck a la Victory.

 

Se vad som är rimligt, jmfr med verkliga fartyg.

Please note: I copied what we had so far into a new thread. Please do not answer to this post. I´ll update the rules should we agree on something new. Thank you. I moved the old thread to our archives.]

 

Point 1: Hull strength.

a ) Relative composite hull strength should not drop below 1.00 except for the light fast combattants (<6000 tons standard; >24kn)

B ) Relative cross-sectional hull strength of light fast combattants of 0-3,000 tons standard should not drop below 0.5

c ) In general, light fast combattants of 3,0001-4,500 tons standard can have a minimum relative composite hull strength of 0.75 as long as it does not cross the limit as given in point 1b.

d ) In general, light fast combattants between 4500 tons and 6000 tons standard can have a minimum relative composite hull strength of 0.9

 

Point 2: Length:Beam ratio.

(as currently proposed)

a ) Ships of 8000 tons and smaller => maximum 12:1

b ) Ships bigger than 8000 tons => maximum 10:1

 

Point 3: Switching mains and secondaries.

Can only be done with regular main and secondary turrets (use of the funky options should be avoided) and when no superfiring main guns are present. Edit the design so it properly gives the main guns first and the secondaries second, armor and "shells needed to sink ship" bits to make it easier to read.

 

Point 4: Stability.

Try to avoid designing ships with a stability of 1.00 since the bug might kick in and increase the number of torpedoes your ship can take. Hopefully this has been sorted out with the next version of Spring Sharp. Note that with Springstyle you will get a stability warning at the point where Spring Sharp encounters the bug. Spring Sharp does not give a stability warning at that point.

 

Point 5: Block Coefficient

No bc less than 0.38 is allowed. Only small high speed planing or semi-planing hulls are allowed to have a bc smaller than that.

 

Point 6: In the regard of simming a carrier that uses bulges, one should use the hull beam to calculate the number of planes (lenght x beam / 750 for imperial units) and not the beam over the bulges.

 

Lite designregler

 

Carriers.

 

Spring Style is designed for ships armed

primarily with guns, but carriers become important from the end of World War I on. Here is a method for simming carriers:

 

Design the ship as you normally would. Put in as much

miscellaneous weight" as you can - that will usually

determine how big an airgroup your CV can carry. Now,

get out your pocket calculator. You'll make two pretty simple calculations, each of which gives a possible airgroup limit.

 

1) Take the square root of miscellaneous weight; e.g., if miscellaneous weight is 10,000 tons, the eight-based limit for your carrier is 100 aircraft. (In addition, allow at least 25 tons per aircraft, i.e., if miscellaneous weight is just 100 tons, your ship can carry 4 planes, not 10.)

 

2) Multiply length x beam (both waterline) and divide by 750; e.g., if your CV is 900 ft x 100 ft, the space limit is 120 aircraft.

 

For the metric gang, divide by 70 instead; if your CV is 280 metres x 30 metres, the size limit is also 120 aircraft.

 

Use waterline dimensions (if available), NOT flight deck dimensions; they can vary a lot more, and we want a consistant rule.

 

Your carrier's airgroup is whichever number is LOWER.

So in the example above, your CV has an airgroup of 100

aircraft. (That is for WW II or earlier planes. For postwar CVs with jets, I'd estimate about 2/3 of the airgroup calculated by this method.) Usually, the weight rule gives a lower number of planes and thus sets the limit; the size limit will usually apply to CVEs converted from merchant ships with a great deal of miscellaneous weight.

 

Use a word processor, etc., to adjust your ship report. I list the air group above guns, since it is obviously a carrier's main armament!

Conversions: If you convert a battlecruiser, etc., to a CV, follow the same basic procedure. Start with the original ship, modify main guns, armor, etc., put in miscellaneous weight (i.e., the flight deck), and there is your carrier.

 

Note: This rule works pretty well for American and Japanese carriers. British-type carriers with armored flight decks may require a lower airgroup limit, perhaps 2/3 the number generated by this rule."
