The Proton Pack

[Kurotenshi]

Kurotech Inc. presents:

The Proton Pack

*EDIT: new version can be found here*

A rather unique looking rocket in the real world, now brought to KSP! And it comes with several prebuilt payloads. The goal of this pack is an aesthetically pleasing, yet still functional craft. This is why most payloads won’t be super detailed, so the part counts don’t skyrocket, but you’ll definitely recognize them. If a payload has solar panels, press 0 to deploy them.

[Majorjim!]

That Proton is ace.

Really nice fairing too. GJ!

[WooDzor]

Oh I had never heard of the TKS.. *puts on to build list*

Lovely rocket though never really build Russian rockets. I could never get them quite right maybe i'll give it another go soon

[Darth Lazarus]

hrmmm .... Kuro ... mind if i deconstruct your Proton to chek on some details? cause i have soem trouble with mine ... oh where did you got the infos about the second stage enginecover?

hrmmm .... Kuro ... mind if i deconstruct your Proton to chek on some details? cause i have soem trouble with mine ... oh where did you got the infos about the second stage enginecover?

I believe the second stage interstage stays attached to the second stage.

It should go like this:

1. Second stage ignition (the engines start while the first stage engines are still firing)
   
2. First stage cutoff
   
3. First stage separation
   

2.3.1 Proton Booster Ascent

The Proton LV uses a standard ascent trajectory to place the Orbital Unit (OU), which includes the Breeze

M, PLA and SC, into a 170 km to 230 km (92 nmi to 124 nmi) low-earth circular parking orbit inclined at 51.5â°

after the first Breeze M engine firing. A standard ascent trajectory is required to meet jettisoned stage and

payload fairing (PLF) impact point constraints. The use of a standard ascent trajectory also simplifies lower

ascent mission design and related analysis, thereby increasing system reliability. Once the OU is in the

standard parking orbit the SC can be transferred to its target orbit by the Breeze M.

Table 2.3.1-1 lists the time of occurrence for major ascent events for a typical launch. Figure 2.3.1-1

pictorially illustrates a typical Proton ascent into the standard parking orbit and subsequent Breeze M flight to

the target orbit.

At approximately T-1.75 s, the six Stage 1 RD-276 engines are commanded to start at 40% of full thrust. Full

thrust is commanded at T-0.15 s. Lift-off confirmation is signaled at T+0.5 s. The staged ignition sequence

allows verification that all engines are functioning nominally before being committed to launch. The LV

executes a roll maneuver beginning at T+10 s to align the flight azimuth to the desired direction.

Stage 2’s three RD-0210 and one RD-0211 engines are commanded to ignite at 119 s and are commanded

to full thrust when Stage 1 is jettisoned at 123 s. Stage 3’s vernier engines are ignited at 332 s followed by

Stage 2 shutdown at 334 s.

Stage 2 separation occurs after six small, solid retro-fire motors are ignited at 335 s into flight. Stage 3’s

single RD-0213 main engine is ignited at 338 s. PLF jettison typically occurs at 348 s into flight, depending

on SC heating constraints. The Stage 3 main engine burns until shutdown at 576 s. The four vernier engines

burn for an additional 12 s and are shutdown at 588 s.

The Stage 3 retro-fire motors are ignited and Stage 3 is separated from the Breeze M or SC. Figure 2.3.1-2

shows ascent ground track and jettison points, and ground tracking station acquisition times. Figure 2.3.1-3

shows the times and values for the vehicle’s inertial velocity, altitude, longitudinal acceleration, and dynamic

pressure.

@WooDzor

Yeah, the TKS is actually pretty interesting. It's basically a small station module with a crew capsule attached. The "station part" (aka the FGB) later became the basis for the Mir modules (except for the core, that was based on Salyut), as well as Zarya and Nauka for the ISS. The TKS was actually intended as a resupply craft for the Almaz stations, but then switched over to the Salyut 6 and 7. It never flew manned before it was cancelled, unfortunately.

@Darth

I simply based it of launch simulation from Orbiter, the first one you find on youtube I just watched it again and noticed some small mistakes, which I've quickly fixed now. Just some simple staging differences, like the exact number of seperatrons and how the first stage detaches. It doesn't quite start up before the first stage burns out, but that's mainly because of explosion hazard and not making launching it too complicated. And feel free to tear it apart. I do use editor extensions though, to align stuff better with vertical snap, and sometime to surface attach things that aren't surface attachable

@ Kuro

found the video: finaly a very good video about the proton ! thx a lot... and yes the enginecover of the second stage. i knew some pictures of the second stage in a russian VAB and you can clearly see the conic shape of the end with the four nozzles. i always wondered if they drop the engine cover during flight like the Soyuz rocket. and so it is ! perfect. but i wonder about the payloadfairings. judging after some animations and official documents, the fairings are letision AFTER third stage ignition and not during secondstage burn. needs more investigation

but rework of Proton M with Breez-M in progress, will show it later

edit_ dang ! can't give you rep

it's quite similar to the Gemini MOL, I build that one last weekend. good fun these small science/intelligence modules

[Kurotenshi]

Yeah, they're great, it's a shame they were so underused. Gemini MOL did get a lot less far than the TKS though, and I love how you see the vast difference between Russian and US development, even if they build something similar.

Also Darth, the fairing does drop after 3rd stage ignites, like mine does. It's in Giggle's source:

Stage 2 separation occurs after six small, solid retro-fire motors are ignited at 335 s into flight. Stage 3’s

single RD-0213 main engine is ignited at 338 s. PLF jettison typically occurs at 348 s into flight, depending

on SC heating constraints.

The PLF here stand for PayLoad Fairing

[Giggleplex777]

and yes the enginecover of the second stage. i knew some pictures of the second stage in a russian VAB and you can clearly see the conic shape of the end with the four nozzles. i always wondered if they drop the engine cover during flight like the Soyuz rocket. and so it is ! perfect.

I'm 95% sure the second stage interstage does not separate from the second stage. Sgt_flyer and I did extensive research of this while we were building our own replicas and we found no official evidence that it was jettisoned. The engines are so close to the interstage that if the interstage was detachable, it would have less than 30cm clearance from the engine bells. Furthermore, the video isn't completely accurate; it's just an artist's impression.

[Kurotenshi]

There we go, added the Mir station, all modules are launched on the Proton, as they should.

The Core module is based on the Salyuts, and has it's own propulsion. Kvant 1 has and FGB derived FSM (Functional Service Module) that gets it to the station. The other modules are FGB based modules, are self propelled, and can dock on their own.

I left off the girders, because that would raise the part count, and also make construction more complex. Normally only one solar panel added to Kvant 1 came from the Kristall module, and was later replaced during a shuttle visit, as well as adding the second one. All this (girders and solar panels) was done during EVAs, which could be done with KAS, but I like to keep it stock.

Have fun building your own Mir without melting your computer

[spaceman1999]

I can't figure out how you built that TKS! I've tried several times to replicate it but can't... Reveal your secrets wizard!

[Kurotenshi]

Lots and lots of part clipping, and some help from editor extensions I mainly use the vertical attachment and enabling surface attachment for node-attached parts.

Have you tried tearing it to bits part by part, and clipping the camera trough it? I find those often help to figure out how a craft is built.

[LABHOUSE]

It is a bit wider in real life... but still good. Try using a kerbodyne tank with radial orange tanks on the sides so it will be the current size.

Edited November 12, 2014 by LABHOUSE

[Kurotenshi]

Current size?

And I chose for a 2.5m based one, instead of 3.75m based, as that is more to scale for both the prebuilt payloads, as well as payload capacity of the LV. the capacity of a 3.75m based one would probably be far higher, but more unrealistic.
