Dispatches from the Front pg. 2

Doing some site cleaning around here.  I've deleted some images from some folders that aren't needed for site references but are linked to by various bots, forums and search engines. It is annoying a bit to see Google download Okun's naval armor slope multiplier table jpg in an Australian roof pitch slope search.  I don't need to support these with my bandwidth.

I looked into finding the exact area of the cast girder that joins the front hull plates on the T-34.  I've fiddled with the values for this over years.  A US publication gives a cross-section of two types.  The older cast type is rounder and covers a larger area.  The newer type is has more of an angle but doesn't attribute much to the overall area protected.  In fact it doesn't cover even half a location for a T-34/85.  So it basically is ignored.

I fixed some of the links to my dad's WWII photo collection off the Naval Page.
I also go rid of some old dispatches as the space can be better used for other things.
I was checking the connection log and found that people were sending comments with the panel on the Airland page.  Unfortunately that box is no longer working.

I added to the After Action Report of the battle
around Ruaray.

There have been a number of threads about Tiger losses in Normandy June 1944.  One such was about losses of just three Tigers in the battle around the village of Ruaray.  I thought I might jump in to try to sort things out.

To download Train Fever  I had to sign up with Steam and install a Steam program.  Then I was able to download the game. As I keep my software development/game machine off the internet as much as possible I use an old XP machine for email/browsing. The problem would be getting the game off my email computer and onto my game machine.  That wasn't to be a problem as my anti-virus program detected the 'Win32/Heur' virus lurking in the Train Fever program and removed the game.
-----Thus ends the folly.

Humble Bumdle Trouble.  Most people don't know it but I worked on the Railroad Tycoon II and III games for awhile as a play-tester and map maker.  I even had the biggest fan site for awhile until in 2006 I turned the content over to Hawk and Badger.  So when I saw that there was a new rail game, Train Fever, with good graphics and some other nice features I decided to buy a copy.  Unfortunately the link from the Humble Bumdle - PayPal to Steam did not work quite right.  I never was able to download my game though they billed me for it.  So my complaint to support got a reply saying their tech ninjas were working on the problem.  It's been over a week and all I got so far was another email saying that the ninjas were still working.  So maybe the ninjas committed hara-kari or have gone ronin

on them.

I corrected a bug in the little Dispersion program.

There is some question on the trajectory ballistics of the 75mm L70 KwK42. Frankly, I thought I had the data, but when I looked I had only considered one source. It seems there are several equally reliable sources.  So I made a research page on this.  For my use I will throw the data into my ballistics program and see if the physics of the data actually makes sense.  Research page.

We are working to fix some bug in PCO.  The hulldown checking calculation is taking some time.  I'm not a C++ programmer so I can't help much except with logic and concept.

I reworked the WWI Naval rules using the corrections to the NAaB program.  I include a few notes on each gun table so I know what factors I used for the calculation.  They go: shell weight, MV, ballistic coefficient,

The NaaB error should affect the horizontal penetration values on Seas of War.   But it doesn't seem to change very much.  The 16" shell only changes penetration ranges by on average about 3,000 meters.  So in the long run it doesn't change things much.  Maybe the error affects smaller shells more.  I will eventually update all the Seas of War tables but it isn't that urgent right now.

Checking other sites and some interesting tests.   88mm vs T-34.

Somewhere the menu item of Boot Camp got lost.  So it has returned.

Using a true ballistics equation in my ballistic accuracy program instead of a simple algorithm has an advantage in that some weird things come to light.  One of them is that when combined with the range error effect it is found that an anti-tank gun would be more accurate than the same gun on a tank.  This comes about because the trajectory of a shell passing over the target to hit the incorrect range will miss by a smaller amount when fired from a lower position.  (This could just be an aberration of the mathematical construction.) Also, this assumes that both the tank gunner and the AT gun gunner mis-estimate the range the same.  It may be that the gunner at a higher position can estimate the range better so would counter any trajectory disadvantage.  I don't know any way to determine that.

Updated some Research pages for clarity and errors.
