Razgriz1 Posted June 26 Share Posted June 26 I'm going to ask this here since y'all have all kinds of reference documents saved away: Does anyone know when Centaur switched from using HTP reaction control thrusters to hydrazine? I suspect it was Centaur II (Atlas II/III), but I have yet to find any source to back that up. Quote Link to comment Share on other sites More sharing options...

We're not anywhere close to release but I don't think the scope will get any wider.

You can think of Mariner 8/9 as being an orbital version of 6/7. In addition to the propulsion module, there are some other changes for 8/9 - the solar panels are on outriggers instead of connecting to the top edges of the core, the LGA is shorter, the HGA is moved outboard, and a medium gain horn antenna was added. The core (or at least, it's structure) was shared with the Mariners all the way back to 3, while the solars (save the aforementioned mount changes), star trackers, and science platform are shared with 6/7.

Centaur D.1AR is not a Centaur D.1A with new insulation like Wikipeda would suggest. Rather it is the Shuttle Centaur D.1R brought to life. D.1R was "stepped over" for what became Centaur G/G'. But during the process to "man rate" and "Shuttlefy" the Centaur, they had already made the changes to eliminate the highly reactive H2O2 from the stage. Hydrazine, while a reactive chemical, is much easier to control than Hydrogen Peroxide at the percentages we are talking about. Since all future RL10s would be Hydrogen Peroxide free, A new Centaur Stage had to be made. NASA dusted off the now almost 10 year old plans for D.1R and designed a new insulation shell, since the D.1A's shell was not comparable and was in fact out of production with no tooling remaining. Why NASA couldn't contract for the D.1A's insulation to be made? Simple this was post Challenger failure.... Prior to Challenger, the manufactures were ordered to destroy any tooling for out of production stages. Atlas Centaur was considered out of production. The tooling had yet to be destroyed for Atlas or centaur tank-age, but the subcontractor for the insulation panels did destroy their molds. This is also why the RS27 power block replaces the LR89 powerblock on Atlas I Because the LR89 powerblock tooling no longer existed. RS27 is a derivative of LR79... so is LR89 so it fits! (And yes it is MUCH more nuanced than I am saying here... this is a sorta TL:DR version of what actually happened. Quote Link to comment Share on other sites More sharing options...

Pappystein Posted June 26 Share Posted June 26 (edited) How to build the Atlas F ICBM into a space launcher!: ps this is the ORIGIONAL proposed Atlas F... not what was actually built! Step 1) Realize this thing's Fuel tanks are TALLER than Atlas III. Step 1a) wait, Centaur Jr comes from here?! Step 2) Reveal hidden contents You are going to be using several tanks in this setup. Thankfully it is just two parts, The Atlas Extension Balloon tank x3 in two different lenghts! And then the base Atlas Tankage. Your First Atlas Extension Balloon Tank, should be set to J1-A/U Your Second And Third Atlas Extension Balloon Tanks should both be set to SLV-3C Your Atlas 3400 Core Tank, should be set to Atlas F (or floating pipes will be a thing!) Your Engine selection: Using the Saturn H-1D model, you will set the outer two engines to H-2-250kN. The Center sustainer engine will be an H-1D-1973 The Original Atlas F proposal from 1960ish suggested that an improved LR105 would be developed Utilizing design features from the X-1 engine. X-1 is the testbed engine that Rocketdyne developed the H-2 Turbopump on (or at least started too) as well as all the thrust improvements over the years of the Saturn and then later RS-27 program for Delta. For our purposes however it is just easier for an H-1D to be utilized. Incidentally the H-1C, while probably more correct (no gimbal) is not advisable. In my test flight I had a skirt hangup on it. I did not investigate. Just like any Atlas, fee free to investigate at what mass your rocket can attain 1:1 TWR with just the core Sustainer (H-1D) and twin LR-101s running (do so by removing fuel until the TWR is 1:1) then, re-attach the skirt, check the TWR, And set that number (in my case it was 2.8 TWR with light fuel and all 5 engines) as your jettison point for the skirt. I do have recovery programs in my game so the parachutes on the Atlas E/F skirt will be recovered to save funds. Magnificant! you have an Atlas F(ICBM) derived booster. YEs this thing is truly the big stick (lenght wise) in the 10ft Bossart designed balloon Atlases. It is 16" longer than Atlas III between engine top and Centaur bottom. NOTES: This Atlas F ICBM is not what was eventually built. Convair knew a new generation of Nuclear warheads were coming, and logically were not told anything about their specification. They figured a growth in mass of about 50% (real ballpark here) and designed an Atlas that could haul that extra throw-weight with the same range performance as an Atlas D/E. This monster never left the drawing board and was replaced by the "Repeat Atlas E with new avionics" that we know as the Atlas F today. The H-2 engine was already under development when this program started and was a known factor for Convair and Rocketdyne. Remember the H-2 is just an H-1 with a re-designed combustion chamber (bigger injectors) and a higher speed Turbo-pump. CobaltWolf has already included the H-2 in two configurations on the H-1D based on the reaserch that several of us compiled together on this forum a couple years ago. The H-2 Engines in this build need to be rotated 90 degrees or they stick out of the skirt excessively I flew an Agena based payload for a future set of posts on this test flight, the Atlas F ICBM, was able to get the payload to a 200km orbit in JNSQ without issues. The Agena then finished circularization. Bonus, the test build I did with Atlas III tankage (this is UGLY A F) The tank choices I gave you above, result in a tank stack aproximatly 0.5 meters taller than the Atlas III stack shown here. That it about the difference between the two rockets in lenght. Edited June 26 by Pappystein Clarification. Thanks Zorg! Quote Link to comment Share on other sites More sharing options...
Zorg Posted June 26 Share Posted June 26 I think its worth clarifying for the un-initiated this Atlas F is a completely different beast to the Atlas F we actually ended up actually getting.
