KissSh0t Posted November 23, 2013 Author Share Posted November 23, 2013 RocketTurtle.. Go to the first page of this thread.. I have a few SSTO's there that you could try out or use to learn from.Interplanetary SSTO's can be tricky.. If I was you start of by just trying to get into orbit and then landing back at the runway after 1 orbit. Quote Link to comment Share on other sites More sharing options...
Deadweasel Posted November 23, 2013 Share Posted November 23, 2013 I'm trying to make it interplanetary... I suck at SSTO's so much. :CThat's not a fail. That's what we in the business world like to call an "opportunity". There's also another term we use for such cases, and in this case it's probably more appropriate: "challenge".I use FuelTastic to generate fuel as I go, allowing all of my SSTOs (that actually work) to go even farther once they reach orbit. The power cost is pretty high, but patience pays off when you land that sucker at Laythe. It's not cheating; it's "introducing a new dynamic to create a positive deviation from the paradigm".(Okay, enough of that. It's making me dry-heave!)

RocketTurtle Posted November 23, 2013 Share Posted November 23, 2013 I can do that. I then add a nuke and everything from there out goes to hell... Quote Link to comment Share on other sites More sharing options...
Mesklin Posted November 23, 2013 Share Posted November 23, 2013 Only two words - too heavy, delete all I-Beams and almost all RCS tanks, 2 RCS balls is enough. As per my experience for two turbo jets maximum weight is 32-33 t Quote Link to comment Share on other sites More sharing options...
KissSh0t Posted November 23, 2013 Author Share Posted November 23, 2013 Perhaps you should build larger if you are having such difficulties getting a small SSTO like that into orbit when a nuclear engine is in the mix///Basically your craft as it is... is too heavy.. and does not have the power at altitude to get up to speed.Try building an SSTO from scratch using 4 to 6 TurboJets with only 2 Nuclear Rockets and enough Air intakes to give you about 10 to 15 Air Intake.You can circularize an orbit using only Jet Engines.Challenging! mwhahahahaha~ Quote Link to comment Share on other sites More sharing options...
Exothermos Posted November 23, 2013 Share Posted November 23, 2013 My big Dropship nears completion. It's mission profile is to deliver moon base parts. It's getting there. A few more missions, and some tweaking are needed.The most recent mission revealed a surprising but minor CoT problem from the main horizontal rockets. Lots of little fixes to make, but it's in the home stretch!An over-engined variety was hilarious, but ultimately too silly to justify.

RocketTurtle Posted November 23, 2013 Share Posted November 23, 2013 Does this look like it will be too heavy? Quote Link to comment Share on other sites More sharing options...

Overfloater Posted November 23, 2013 Share Posted November 23, 2013 (edited) Airhog MK-IICapable of a Mun or Minmus round trip. If I would have been careful and haven't forgotten to bring parachutes with me, I could've made a Duna round trip.In this case it's a one way trip and the pilot awaits rescue in Duna orbit...Your new home, buddy!Nope! This is as far as you'll get this time...This later led to the development of the Airhog Mk-II Crew Shuttle:Javascript is disabled.

Fellow314 Posted November 23, 2013 Share Posted November 23, 2013 Does this look like it will be too heavy?I think so.(Caution, shameless self plug ahead)Take a look at the first plane in my thread here:http://forum.kerbalspaceprogram.com/threads/58503-X-craftTwo long tanks, one jet fuel tank and it makes Duna. (just )Maybe you want to try increasing delta V by losing weight rather than adding fuel? - see this excellent NASA piece recently posted here by someone I would credit if I could remember who it was:http://www.nasa.gov/mission_pages/station/expeditions/expedition30/tryanny.html Quote Link to comment Share on other sites More sharing options...
RocketTurtle Posted November 23, 2013 Share Posted November 23, 2013 Gr. It screams on the jets, but once again it can't raise its apoapsis to the desired 100 km orbit with the nukes. Quote Link to comment Share on other sites More sharing options...

KissSh0t Posted November 23, 2013 Author Share Posted November 23, 2013 Gr. It screams on the jets, but once again it can't raise its apoapsis to the desired 100 km orbit with the nukes.Lighten it.. keep tweaking.. Basically make an aircraft that can fly on 30/40 thousand without cutting out on the Jet Engines.. and go for speed at that altitude... Once you are as close to 2000m/s as you can get, turn off Jet Engines + Close Air Intakes, and do the rest with rockets.Remembering to throttle down as your craft gets to the limit of the air intake.. As long as you are still accelerating and not falling.. Only slightly Climbing.. At the very limit your craft can fly level.. you will be able to get into orbit~ It's a bit different than flying with Simple Rockets.

RocketTurtle Posted November 23, 2013 Share Posted November 23, 2013 Do you think you could fly it maybe and give recommendations on what to change, and how to do it?If so that would be awesome. :3https://docs.google.com/file/d/0B6r1qNKmBVMebW5DSG5kNDBkUEk/editI'm still learning all this.

RocketTurtle Posted November 23, 2013 Share Posted November 23, 2013 Alright, thanks. Quote Link to comment Share on other sites More sharing options...
KissSh0t Posted November 23, 2013 Author Share Posted November 23, 2013 You are almost there... what the design lacks is air intake.. I was having troubles getting the speed needed before switching to the nuclear rockets. If you provide it with more air intake I believe this design will be able to get orbital.Right now your design has a max air intake of 4.80 ... Try to get it to 10.One thing I noticed while testing it was the top and bottom wing not being connected to one another. Quote Link to comment Share on other sites More sharing options...
RocketTurtle Posted November 23, 2013 Share Posted November 23, 2013 Alright, I'll add more intakes. Also, how can I make each jet have the same fuel amount? As you can see, the middle one looses fuel quicker. Quote Link to comment Share on other sites More sharing options...
KissSh0t Posted November 23, 2013 Author Share Posted November 23, 2013 (edited) Connect all fuel tanks both ways.. so fuel can run back and forth.A good way of testing fuel drain is to build the body of the craft without the wings, load it up on the runway, put the break on and turn the engines on, maybe throttling down so the engines don't push too hard on the craft with it's breaks on xDWatching where the fuel drains from.

RocketTurtle Posted November 23, 2013 Share Posted November 23, 2013 Do you think 9.6 is enough air? Quote Link to comment Share on other sites More sharing options...
RocketTurtle Posted November 23, 2013 Share Posted November 23, 2013 Clearly not.Me: "Almost there!!!" Stupid air. Quote Link to comment Share on other sites More sharing options...
RocketTurtle Posted November 24, 2013 Share Posted November 24, 2013 Greaaat... got it to orbit... with like no fuel... this thing is pointless... now I have to make it Duna capable...I hate SSTO's sometimes. Edit: Should I make some of the jet fuel tanks LFO tanks?Edit edit: No, that would increase weight, this thing can barely get into orbit anyways...EDIT EDIT EDIT: Nevermind, I'm missing fuel lines, it actually might have enough...

RocketTurtle Posted November 24, 2013 Share Posted November 24, 2013 (Sorry for like, quadruple posting)Well, I'm not in the mood to test it... anyone else want to?https://drive.google.com/file/d/0B6r1qNKmBVMeUFgyNGtWZVN2SlU/edit?usp=sharing Quote Link to comment Share on other sites More sharing options...
KissSh0t Posted November 24, 2013 Author Share Posted November 24, 2013 (edited) That's the challenge of SSTO!! It can be tricky.. but when you do it right... it is quite fun.You actually have lots of fuel after getting into orbit!!
