Project Atlas ICBM development

[Star Voyager]

Good morning gentlemen,
For Mr. MJR, do you plan on doing something major to the warhead? By the way, on your scenario, it should say dawn, not dusk.

 

[MJR]

I'll change that. Right now I am renovating the inside of the warhead to look interesting and not dull. I'll upload it after I am done. Major? I don't know about that. Close to major though.

I got the interior of the W-38 done.

I am not sure, but are any of the engines jettisoned during the flight?

 

[astrosammy]

Yes, a part is seperated. Just take a look at the project mercury add-on.

I am not sure, but are any of the engines jettisoned during the flight?

You mean on the Atlas? Yes, the two outer booster engines. They're attached to a "drop-skirt" which is jettisoned in-flight leaving the center sustainer burning alone.

 

[MJR]

Thanks. I guess I need to update the Atlas ICBM to have the booster jettison during flight. Another quick question, how long do the two boosters burn for?

 

[MJR]

Old warhead mesh.

 

[astrosammy]

Here are some screenshots of the boosters, and I'll look how long they burn:

Here some informations on the booster, from http://www.astronautix.com/lvs/atlas.htm#HGM-16F

Stage0: 1 x Atlas MA-3. Gross Mass: 3,174 kg (6,997 lb). Empty Mass: 3,174 kg (6,997 lb). Motor: 2 x LR89-5. Thrust (vac): 1,644.960 kN (369,802 lbf). Isp: 290 sec. Burn time: 120 sec. Length: 0.00 m ( ft). Diameter: 4.90 m (16.00 ft). Propellants: Lox/Kerosene.

 

[MJR]

I can do that.

There. Another update. It has a better warhead mesh. Warhead interior with universal warning texture.

After editing the mesh to make the sustainer engines jettison during flight. I am done with the Atlas ICBM. I have been informed that tommorrow there will be a guidance file for the ICBM and a new Altus Base.

Good morning gentlemen,
For Mr. MJR, not quite:

View attachment 2828

I hope this isn't too much touble .

 

[MJR]

The USAIRFORCE? I just happened to notice that. I fixed it.

 

[astrosammy]

I have a CTD when the booster seperates.

Under STAGE_1

eng_4=(0,1.996,-6.836)
eng_5=(0,-1.996,-6.836)

should be:

eng_1=(0,1.996,-6.836)
eng_2=(0,-1.996,-6.836)

to solve the CTD.

And you should add an

eng_3=(0,0,-10.0)

to that, to make the center engine burning.

 

[astrosammy]

OK, here's the guidance. It brings you down into the sea north of Russia, it can hit Russia if you add more fuel. The warhead seems to have bad aerodynamics, it reenters very fast.

 

[MJR]

Thanks. I'll take a look at the warhead and see if I can fix it.

This next update adds a guidance file.

A picture

I've been testing and flying both the Atlas-ICBM and now the Atlas-A. I reset the COG to 0.1 on both and and they look frakking AWSOME launching from the Canaveral Atlas site.
I touched up the booster skirt and side covers on the Atlas-A to change the material from factory coating red to a light black so it looked more like the Atlas-A that was on static display at the Wright-Patterson AFB museum back in the 70s.
I can hit Baikonur from either Canaveral or Vandenburg with a little carefull attention to my heading. From Canaveral I use 15.50 degrees.

 

[MJR]

I am glad you like it.
