CT Only: Small Craft power plants, maneuver drives, and fuel tonnage

[snrdg082102]

Hello again all,

I vaguely recall that an optional construction rule was introduced that allowed small craft to carry less than 1 ton of fuel instead of the 1 ton of fuel in CT LBB 5 HG 2.

I also think the rule allowed the power plant and maneuver drive to be less than 1 ton as required by CT LBB 5 HG2.

Can anyone please confirm my vague recollection and provide the source and page numbers if I'm not out to lunch?

heh. that was my third house rule back in the early 80's ....

Just as a matter of clarity for the many board readers who do not know HG2 well...

the large craft design requires all bridges, drives and fuel to be rounded up to full tons for the design.
Small craft round to the 10th (0.1) for drives and fuel, with a minimum of 1Td each.

Note that CT A5:TCS does not change this...
nor does T20...

Actually small craft are built to two decimal places - see example of the Gnat fighter. Rounding would be to the 100th (0.01) going by this example.

Evening PDT flykiller, aramis, and Mike Wightman,

Thank all of you for replying to my question.

The issue with designs that use house rules is that the rules as far as I can tell are not stated which means that my attempt using the construction rules to recreate the design fails. A couple of examples are the X-boat not having a power plant and the X-boat tender's mobile turrets and the pop-up turret.

Apparently from the reply given by aramis my memory is once more leading me astray. Thank you aramis for the clarification however the CT LBB 5 HG 2 Battle Cruiser Kinunir design example shows the jump drive as being 62.5 tons, maneuver drive as 137.5 tons, and the power plant as 87.5 tons. The jump drive requires 500 tons of fuel and the power plant requires 87.5 tons of fuel.

CT LBB 5 HG2 Small Craft Drives p. 34 second sentence: "No maneuver drive or power plant may be less than one ton; when a computation produces a drive of less than one ton, use the value of one ton (fractional drive values above one ton, such as 1.7 tons, may be retained instead of rounding)."

CT LBB 5 HG2 p. 23 indicates that the calculated fuel tonnage allows four weeks of operations and is calculated using the equation: 1% x Ship Tonnage x Power Plant rating. Which also appears to be the same equation for calculating Energy Points: The Energy Point equation is E = 0.01MPn where M is ship tonnage and Pn is the power plant number or rating.

CT Adventure 1 CP-10798.92 fighter's fuel tankage requirement is 1% x 6 x 5 = .6 x 5 = 0.3 tons and has an EP of 0.01 x 6 x 5 = 0.6 x 5 = 0.3. If the fuel tankage is for four weeks the fighter can operate for a bit over 12 weeks with 1 ton of fuel. When I upgraded the computer from Model 1 to Model 2 the fighter exceeds the hull space by 0.5 tons. By allowing a fraction fuel tonnage of either 0.5 or 0.3 the installation of a Model 2 computer would not exceed the 6 tons of the fighter. As things stand and my math is correct the CP-10798.92 fighter is not, in my opinion, a valid design.

I am hoping to be able to post my review of the CP-10798.92 fighter from JTAS 8 in the file section since I still have not figured out how to quickly build a table.

Yes, Mike Wightman the CT Adventure 5 TCS Gnat Fighter example on pp. 22-23 does show that calculations are to two decimal places for tonnage.

Again thank you for your replies.

In either Numbers (apple), Sheets (google), or Excel...

1. build the table in the spreadsheet.
2. in a row down from the bottom, insert =concatenate("[td]",A1,"[/td]")
3. select a range the same size (in cells) from that initial one as the original table and fill down and across.
4. in a column after the rightmost of the new version, use the same in the top line, but change the tags to =concatenate"[tr]",a12,b12,c12,...,"[/tr]").
5. Drag copy or select and fill down that one the full length.
6. on a new line, do a =concatenate("[table]",(all the row cumulativess from steps 4-5),"[/table]")
7. copy the value of that cell
8. paste into COTI.

That's how *I* do it.

Thank you very much for providing a alternate method for building a table. I'll try to create a table, but I am worried that my efforts will result in not being able to edit my work once copied in the COTI window.

Evening aramis,

Save a copy... if you need to edit the table, edit it in the spreadsheet... it'll update the big cell with it all, so you then just need the final copy-n-paste.

Also note: some spreadsheets take paste from HTML tables pretty well..

The following example, I pasted into Sheets directly from the finished post, it properly put it all into cells correctly, then applied the process to generate the BBCode...

Note those quotes? I should edit them out, but it's a minor issue, as they're added when you copy from Sheets. (Normally, now, I use Pages. I used to use Excel, then Appleworks... But students now use Sheets for most things, so...)

Thank you for providing me with more help on putting together a table. I'm still not at the point that creating the table is at the top of the to-do list.
