Welcome everyone! I opened this thread for the freedom of uploading the pictures of and discussing the space shuttles that you have made. Stable space shuttles are hard to build, especially if the 'Vector" nozzles are being used. So I thought of creating this thread for you to upload the pictures of your space shuttles or even .craft files to let others see how your shuttles look like. You have the freedom to post your own space shuttle designs, or replicas, mods are allowed, it's just important that you upload shuttle pictures. Screenshots can be taken by using the F1 key on your keyboard while in KSP. Using the F2 key before taking a screenshot is recommended to disable the UI and show the beauty of your picture. You can also link to a YouTube video for the whole mission with your craft. I can't wait to see your amazing space shuttles!
I am attempting to reach LKO in a air/spacecraft and always stall i use a rocket like engine but am always ending up falling even though i have enough fuel. Why?
After a rousing discussion of side-slung launch vehicle balancing at the following thread... ...I built a full-size Energia-Buran stack and started experimenting with Mun missions. However, the complexities of balancing thrust (even if it's a touch easier than an STS-style shuttle) made me think...just how small an Energia-Buran clone could I manage to make? Meet...the Baby Buran. At a scant 10.3 tonnes, it's hard to imagine anything much smaller. But it does what it's designed to do! No room for solar panels and no mass budget for an RTG, so it's all-battery-powered, with a probe core to allow it to do unmanned missions just like its much, much bigger brother. By default, the battery packs on the orbiter are locked so that only the one on the core booster is drained during ascent. It boasts a tiny heat shield on the underside, just in the right place to protect the cockpit, which also allows it to have a lightweight radial decoupler. "Lemwig" sounded like a vaguely Russian name, I thought! Just like the real Energia-Buran, the core has four engines and each of the Zenit-clone strap-on boosters has 4 locked nozzles and four gimbaling control nozzles. Of course, here they are all the same size, but no one is looking THAT closely. Liftoff! Two of the Oscar-Bs on each side booster are drained to allow a liftoff TWR>1. And Lemwig careens off toward the heavens. The engines are angled to provide roughly consistent thrust as the fuel tanks drain, but it's still a bit of a fight. There is a planned roll-over about halfway through ascent, both to take the pilot out of the airstream and to help maintain a good heading. Glamour shot! Here comes the roll-over. Approaching booster burnout. By this point, I've already used an action group to cut two of the four booster engines to maintain thrust symmetry. Boosters jettison together, just like Energia-Buran. They do not, however, separate and land independently on chutes, landing legs, and retrothrusters. I am not a god. Good trajectory at separation. Throttling down to reduce asymmetric torque below what my reaction wheel can handle. Booster burnout! Turning my battery pack back on and preparing for booster separation. Good separation. My two linear thrusters kick on to push me into orbit. The burn shouldn't actually be too terribly long. Ignore the maneuver node; the apoapse is way higher than I'll actually be going to. Just wanted a good maneuver vector. Isn't it cute? And we've got a good orbit! Granted, that's not a LOT of dV for stuff to do in space, but with a good intercept you could rendezvous with a space station. Or it could be sent up unmanned to rescue a stranded Kerbal, thanks to that probe core. Anyway, with no further ado, here's the deorbit burn! I ended up quickloading because my first attempt didn't get me anywhere near the KSC, and for some reason my landing gear glitched into an odd position. Oh well; can't be helped! Coming in hot, but it's nothing this kool Kerbal can't handle. Honestly was more worried about that landing gear. Hey, lookee there! We just might make it! Nosing forward to get a better glide ratio. Trying to turn...my inclination was a bit off. Burning off remaining monoprop to extend my range and lighten my load. Besides, who wants that nasty hydrazine still in the tanks with an open-cockpit deadstick landing? Looks like a good descent. Lining up for landing. Last-moment corrections. Will I make it? Why, I do believe I will. Here we go! Let's hope that wonky landing gear holds up. Touchdown! And, done. He's happy to be back!
