Isnt there a shortcut to lock staging? Like mod-L or something. i think I saw it... checking... correct Its mod-L or in win case alt-L http://wiki.kerbalspaceprogram.com/wiki/Key_Bindings

Cool planes, but, how much do they weigh and how much do they carry to orbit? I know its cool building them and flying them, but im guessing sending stuff up is still in the realm of rockets...

So when you are cruzing to gain max speed from engines, how much do all those wings help? Or what is your pitch when your engines are at full. Of course im asking those who limit themselves to 3 ram intakes...

So correct me if Im wrong, but at 23km at 1200ms lift for delta wing at 10° would be: L=1200ms*0.01bar*1.9*0.141=0.03 t? For a spaceplane with 10 of those it would be 0.3t which is basically nothing.

I tested radial decouplers as additional suspension for those baloon wheels. Basically 4 wheels around a rockomax 9 and some small engines to lift it. Using translatron i figured that baloon wheels would pop at about 6.5ms landing, while with suspension they would pop at about 8ms. If they landed all at the same time. Probably with smaller weight the speed would go up...

How much does the plane weigh and how many parts?

So guys, how high is your cargo to liftoff mass ratio? Or even cargo to parts ratio

Well not sure if it satisfies your guidelines. Its stock parts (except strechy tank as a placeholder for cargo), it uses mechjeb (for reliable orbital insertion) and it delivers around 25t to orbit with 72 tons launch mass. Bit it is a rocket... Still a SSTO

Yes imgur is better, my bad. Here is it again: Link to gallery: http://imgur.com/a/bH6nu Im kinda new, has anyone else been making turbojet SSTO rockets?

Right, and I was reffering to your coal remark. But yes, the water is gonna be radioactive anyway. Reusing it would increase that level of radioactivity. Not really sure if one can evaporate the water and therefore keep radioactive isotopes in heavy concentrations but smaller volume.

No but it does radioactive pollution nontheless. That is if you are worried about that at all.

Yeah right. Radioactive trace elements Coal is a sedimentary rock formed primarily from accumulated plant matter, and it includes many inorganic minerals and elements which were deposited along with organic material during its formation. As the rest of the Earth's crust, coal also contains low levels of uranium, thorium, and other naturally occurring radioactive isotopes whose release into the environment leads to radioactive contamination. While these substances are present as very small trace impurities, enough coal is burned that significant amounts of these substances are released. A 1,000 MW coal-burning power plant could have an uncontrolled release of as much as 5.2 metric tons per year of uranium (containing 74 pounds (34 kg) of uranium-235) and 12.8 metric tons per year of thorium.[21] In comparison, a 1,000 MW nuclear plant will generate about 30 short tons of high-level radioactive solid packed waste per year.[22] It is estimated that during 1982, US coal burning released 155 times as much uncontrolled radioactivity into the atmosphere as the Three Mile Island incident.[23] The collective radioactivity resulting from all coal burning worldwide between 1937 and 2040 is estimated to be 2,700,000 curies or 0.101 EBq.[21] It should also be noted that during normal operation, the effective dose equivalent from coal plants is 100 times that from nuclear plants.[21] But it is also worth noting that normal operation is a deceiving baseline for comparison: just the Chernobyl nuclear disaster released, in iodine-131 alone, an estimated 1.76 EBq .[24] of radioactivity, a value one order of magnitude above this value for total emissions from all coal burned within a century. But at the same time, it shall also be understood that the iodine-131, the major radioactive substance which comes out in accident situations has a half life of just 8 days. Hence, it is not going to cause as much as damage as the uranium and thorium which are released from coal-fired power plants which have much higher half-lives. Also, the risk of exposure to I-131 can largely be mitigated by the consumption of iodine tablets.

gallery:http://imgur.com/a/bH6nu Basically 25t of cargo to orbit, with a few tons of fuel leftover. Good for a 72t launch mass? Im using turbojets becouse they start at 110kn at start and build up to 225kn at high speeds. While jet engines start from 150kn and drop really fast. Basically I go to 1200ms surface speed with turbojets and then engage rockets while shutting down engines in pairs when Im running out of air...

How much cargo do your planes deliver into orbit?? Basically I have a SSTO rocket with turbojets and for a launch mass of 72t brings 26t extra fuel into orbit (1t for deorbit and landing...). And only 79 parts (+whatever is for cargo). Only non stock part is Jebs mechanical brain, and ok I used stretchy tank for cargo. Specs: 8 turbojets with 8 ram intakes and 24 radial intakes, supplemented by 3 LV-T30s http://www.freeimagehosting.net/eqyu8 http://www.freeimagehosting.net/wim14

The thing that is problematic with SSTOs with low intake number (1 to 2, maybe 3) is that when youre maxxed with jets, you need vertical veilocity so that rockets dont burn fuel against drag much...

You could try getting Logomatic (mod) and test these engines. Isp vs altitude and Power vs speed. At least stock engines work like that, isp only changes with altitude power only with surface speed... I did that for stock turbofan and resoults are interesting.

It says it when you onep its detail with rightclick. Usually it says something in units (U) that is units per second. To get mass flow multiply by 5 (density). Also you get the same info when opening recources tab at the top of your screen. Also, power divided by Isp gives you mass per second... Ok maybe there is a factor 10 in there not sure atm.

I have no idea about B9 jets, but stock ones generate thrust based on speed. Turbojet starts with 115kn at 0 and peaks at 225 at 1000ms, then drops. And they always use air as if they operated at 225kn, so they use more than they should.
