Project Martin A-30 Baltimore

2nd. one also done!

Hello Folks,

Now the Baltimore Mark IV is done with all the corrections.
After the third one, I´ll try my luck with a bomb aimer panel for the three planes before substituting the previous Uploads.

Hello Ivan,
re: Baltimore .air file. You commented that the accelleration was like that of a fighter. This is actually intentional. Accelleration for take-off and just after lift-off appears to be comparable to that of a Spitfire, described as exhilerating by pilots, so that would be correct on the model.
I´m not sure I understand your comment on the model seeming to be low on directional stability. Could you perhaps explain what you mean?

Cheers,
Aleatorylamp
 
Hello Aleatorylamp,

For acceleration purposes, you might still want to check out the propeller pitch range.
Ifyou started with the P-51D AIR file, the numbers will be way off in that area.

Regarding directional stability, I found it quite odd that the aeroplane would crab a bit right after take-off.

Glad you got the VCockpit working.
If you can do that, you probably know about as much about SCASM as I do.

- Ivan.
 
Hello Ivan,

Ha ha! Thanks for your good words. Well, it is VERY abstract and cost me quite some effort to understand and put into effect... but with practice I´ll get better.

It would be great to know enough to make a graphic interface for SCASM... Ho ho, dreams...

I have to SCASM the planes again because I managed to get your prop-blur in as well! Of course, it looks much better.
I set it to make the blades become transparent at 55%, make the blur visible at 50%, and make the transparent disk appear at 30%. I lost the instructions you gave me to this respect on one of my system failures, but I think this more or less fits.

I got a one-degree dihedral in, so that the wing is exactly like in the plans: Upper surface horizontal, lower surface sloping down going inwards.

I also got the lines on the undersurface of wings and tailplane in, (I´d completely forgotten!), and I´m working on the wheelwell-doors now. I don´t think I´ll put in any morelines in, otherwise it will look a bit overdone.

As regards aircraft accelleration, I thought it was OK. However, engine RPM accelleration is slow, so I suppose that could be fixed in the propeller pitch range. The torque would have to be re-adjusted, but that´s no problem. I suppose one would have to move all the columns (either left or right) to make the pitch angle have lower values. I´ll try something...

Then, I ´ll see what I can do about the crabbing. For the moment it´s still quite obscure to me.

Thanks for your comments!
Let´s see what happens. At least the planes are improving, which is the whole point!
Cheers,

Hello Aleatorylamp,

My ambitions are much less grand than yours.
I am still trying to figure out how to do more things in SCASM.
The idea of generating SCASM code from a 3D model is quite beyond my knowledge because I KNOW that I don't know SCASM syntax all that well.
I am still do not understand all of the coding in AF99 files and that is after I have written a dozen programs to manipulate them.
As for SCASM, I have only written one program thus far that manipulates SCASM code and I am so uncertain of its reliability that I am not willing to distribute it.

Be careful about manipulating the propeller tables. You may create some unintended results.
I was confident with the limited manipulation we were doing with the Giants because they were fixed pitch propellers
With a constant speed propeller, the interactions are a bit tougher to see.
Messing around in this area is what is holding up a couple projects of mine because I need to feel comfortable that the tables I generate are going to behave properly.

I don't know if improving planes is the point for me. I would much rather learn how things really work.... Which is probably why I spend so much time experimenting and don't release much.

- Ivan.
 
Hello Ivan,
They are more like dreams than ambitioins... My programming knowledge other than QBasic is what I´ve learnt with SCASM thanks to your indications. Anyway, if there´s room for improvement in my models, it´s also an occasion for me to learn something. It happens all the time, thanks to mistakes!

Experimental things for me alre also interesting - I made a twin-engined tilt-rotor and had to experiment with exaggerated Lift and Drag values for Flaps, but this excluded prop animation - engines are permanently on and props are only a transparent disk. A VTOL Spaceship that could go so fast and high it crashed the simulator at 120000 ft was another experiment. All this is un-releasable too!

Well, I´ll continue with the textures and the panel now.
Cheers,
Aleatorylamp
 
Most corrections done

Hello folks,
I believe I have done most of the corrections (see the screenshots), except for the crabbing which I´m still trying to figure out how to fix, but can´t figure out. It seems only to happen after take-off...
-There is now a cleaned out and working Bomb Aimer Panel! (Thanks Smilo, for your help!)
-Textures are corrected for the pilot´s uniform, lines for underside control surfaces, gearwell doors and bombbay doors.
-Minor bleedthrough improvements in engine nacelles and propellers, and improvement of the prop blur.
-Virtual Cockpit bleedthroughs corrected via SCASM.

Big question: There´s an Autopilot for the Bomb Aimer Panel. Should I leave it in? None of the Baltimores had one...

When I´m sure I haven´t missed anything, I´ll substitute the Baltimores in the SOH upload library.
Cheers,
Aleatorylamp

Hello Aleatorylamp.

The colours on you canopy framing look a bit odd. Is there a reason for the different shades at the top and bottom?

Regarding the crabbing effect / yaw, if it does not bother you, then let it go.
I found it a bit odd, but then again, I don't know how the real aeroplane behaved.

- Ivan.
 
Hello Ivan,
Thanks for your feedback! I see what you mean.

It´s the texturing on the canopyframe which goes together with that of the nose.
OK, I´ve just adjusted the colours so that the cabin struts only get the grey. I also checked from the outside, and it goes well there too.

As regards the yaw/crabbing, I checked the fuel tank positions and contents, but they are OK - that was the culprit for a similar case some time ago. I haven´t read anything about such an effect in the different reports.

The only thing that I found was something different. The Mark V had an annoyingly sensitive horn-balanced rudder which made flying rather tedious, so squadrons that could, replaced fins and rudders from crashed older models.

Cheers,
Aleatorylamp

A new entry has been added to Add-Ons Library, category CFS 1 Aircraft Add-Ons

Description: CFS1 Martin Baltimore Mk.II light attack bomber.

Revised model with a few improvements: Underside textures, Virtual Cockpit and a new bomb aimer´s panel. Early 1942 Martin Baltimore version by Glenn Martin Co., USA, which served mainly in Europe, equipped with two 14-cyl, 1600 Hp Wright GR-2600-A5B radial engines and a top speed of 308 mph at 11500 ft. 100 Mk.II units were built, of a total of 1575 Baltimores. Heavily armed, sturdy and manoueverable, it was a relatively high-performance, accurate bomber. The Mk.II was fitted with dual manual dorsal machine-guns, 4 wing and 4 ventral fixed MG´s, all 0.303 inch. This unit is in khakhi green/brown colour scheme and served in the Mediterranean area. CFS1 .air file, AFX and PCX Source files, DP files, and custom panel for default and FSFS gauges, as well as SCASM-corrected virtual cockpit view. Bomb aimer´s panel by Smilo.

New, corrected Baltimores uploaded.

Hello Folks,

I´ve just uploaded the three new corrected Baltimores. Rami commented that I should be able to edit the old versions to substitute them for the new ones myself, but in the event that I couldn´t, I should just upload new ones and he would delete the old ones.
I was trying to find the way to do it without having to bother Rami, but I´m afraid I haven´t a clue as to how to go about it, other than just uploading the corrected versions.

The old ones had 13, 10 and 15 downloads, but these numbers will probably get lost.

Anyway, unless the links change once Rami has deleted the old ones, these are the new upload links:
Baltimore Mk.V:

Baltimore Mk. IV:

Baltimore Mk.II:
http://www.sim-outhouse.com/sohforum...id=19&id=22125

Smilo has provided a nice bomb aimer panel which I combined with a scale originally from the Norton Bomb Sight for the B-17, so this is a nice novelty for the Baltimores.
I hope you enjoy the improved versions!
Cheers,
Aleatorylamp
 
Hello Folks,
Wow, now it´s a sticky!
This goes to show that combined efforts, with help and input from others, make for a nice job.
So, thanks go to Ivan and Smilo for their help, and NoDice and Hubbabubba for helpful ideas and suggestions!
Now, onto the next one...
Cheers,
Aleatorylamp
