Partial Streamlining

From the CT LBBs 4-7 conversion to MT thread.

The text below represents adding a partial streamlining column and splits configuration 1 into 1n and 1w. The text below has largely been kept in tack from what Major B/Don M wrote as I'm a math person, not a writer.

I strongly believe that we can add to but should not change the values on the table. For example, I have no problem adding a 1w row and entering reasonable value - it doesn't change any existing ship plans. Also, I don't have a problem including the partial streamline column as it doesn't change any existing designs. I don't think we should change existing values in the table unless we know they are actual mistakes: Disk/Dome Airframe should be x 3.0 not x 0.5 for example. I don't have a problem changing a -- to a x 1.0 for clarity. I think one should justify changing a NA to a value in the table, for example if you want to fly an airframe box and you believe the price mod should be x 10.9 just give your rational.

Thanks for your input.

Swiftbrook, recommend an additional modification to the table if we are going to use it as a strawman. I agree with your point above - the original table I posted was something I am continuing to work on as a house rule. If we are discussing an errata entry we should not split needle and wedge.

See an amended draft below this, and someone please check all of the black values on the table to ensure thay are the correct values from the RM. I don't have my book handy with me here and I want to be sure after we've copied and modified it a couple of times now.

It looks like a Christmas version of the Errata might be coming out (at least I'm hopeful) and I'd like this to make the next version.

I have checked the numbers in the RM and they are correct. Speed notes have not been included. I added information about irregular structures and planetoids under unstreamlined. I also added a line under Partially Streamlined from T20.

Are there any other suggestions before we include this in the Errata?

Hi Guys,

Isn't SL PSL and USL in CT the same as AF, SL and USL in MT?

So why introduce PSL into MT?

Best regards,

Ewan

The discussion on why occurred in the MT to CT LBBs 4-7 thread. There is a lengthy discussion there as to the differences and the rational. The main point of this thread is to just hammer out the language.

Where does the Broadsword fit into this? I have seen some awesome videos that show them landing in what appear to be atmosphere.

The Traveller Book states the hull is unstreamlined.

CT Adventure 8 Broadsword: "The ship itself is unstreamlined, although it has sufficient lack of projections to allow it to skim hydrogen from gas giants in order to refuel. It may land on vacuum worlds, but generally interacts with the surface worlds through its complement of 50-ton cutters ..."

In the MT Imperial Encyclopedia the Broadsword configuration is listed as 5USL or Sphere, unstreamline which is not possible according to the MT Referee's Manual (and the errata version). I would change the configuration to 5 PSL as it is the closest fit.

Should be no problem if they have thrust > planet grav.

Only if the atmosphere is 1 or 0.

Doesn't make sense. If it can go slow enough to land on a vacuum world, atm >1 should pose zero problems as it is constant accel and not limited reaction thrust. The authors must not understand the basic science involved.

Still don't see the need.

From the info in the thread it seems you are suggesting downgrading unstreamlined, and changing what is currently unstreamlined into partial streamlining, to achive the same thing (300kph top speed in atmosphere) for more complications and little additional gain.

As I said I don't see the need.

Best regards,

Perfectly fine with this and the rules. Unstreamlined hulls max speed 300kph in atmosphere.

Huh? you _can_ have an unstreamlined Sphere in MT. It doesn't cost you anything to make it streamlined, so you may never wish it otherwise, but if you wish to have it unstreamlined you can have it unstreamlined.

Again partial steamlining is an unessesry complication.

Ewan

Nope. Per the Ref guide the unstreamlined column is "N/A". It is streamlined. The price mod for Config 5 is X1.5 and reflects this.
