  1. Quite the opposite, a lighter object is far less likely to burn up. Heavy objects like a shuttle need more wing surface area to slow down. That's why you usually want to eject extra stages and deplete fuel prior to entry if you know its a toasty ride.
  2. Space shuttles are one of the most difficult things to get stable and overall make work. You have an unsymmetrical vehicle with control surfaces on one side, etc. A much more stable option for small payloads would be to have the orbiter at the top of the rocket, possibly inside a fairing. Far more stable, at the cost of throwing away more of the rocket.
  3. Poor roll control, nose droop when maneuvering, and general instability that requires you to fight it to achieve desired attitude.
  4. I've got a standard heavy lifting SSTO that does it's job pretty darn well. The only issue is that it has some very wonky and downright difficult flight characteristics during descent and landing that make it almost a pain to get on the ground. I've done everything I know to try and get to fly better, but Im stumped. CG is perfectly balanced for all cargo/fuel states. Wings have proper AoA and CoL is behind and slightly above CG for stability. The CG is even balanced so there is no rotational torque. The entire craft is optimized for low drag ascent performance. Not sure if that would create descent instability, but I figured I'd throw the question out and see what smarter people than me think. Craft file: https://nofile.io/f/ZJPtdzjjgum/Heavy+Lifter.craft Any ideas?
  5. It would cost less just to build every building with additional requirements against wind and flooding in hurricane prone areas so that they simply resist the hurricane better than currently than ANY of the proposals above (And we already do this) and let the hurricane kill itself.
  6. In my experience, any gains from using the Whiplash over the Rapier is cancelled out by the inferior falloff of thrust at high speeds by the Whiplash, exactly when you need to get the most speed out of your air-breathing engines. Additionally, having more engines (Nerva/Whiplash) means more frontal area, which increases drag and degrades overall performance. A very aerodynamically slick vehicle with Rapiers can perform very well, especially since drag losses are minimized in the upper atmosphere, where you must use rockets. I've never settled on a liquid-fuel only design that is aerodynamic, practical, and has sufficient thrust throughout the entire flight regime while carrying any appreciable payload. Better to lift your space-optimized vessel into orbit with the SSTO and have the same SSTO grab returning missions for a safe landing with 100% returns.
  7. Question concerning the Mk4-1 Pod, how is it meant to safely re-enter the atmosphere? I feel silly asking but with its overhanging edges, it's presenting an issue for use with a heatshield. Any thoughts?
  8. If you're flying a drag-optimized SSTO into orbit (as it should be), then the last 10km is not really of any importance. Optimizing drag isnt hard to make very low drag rockets, specifically use of bays and fairings. That along with very low thrust requirements for re-entry profiles. I'd stick to 75km.
  9. http://www.strout.net/info/science/delta-v/ Start with your final stage, and as you add stages under it, lock the fuel and take readings off the Build Aid. Works quite well, The Build Aid ought to be in the default game, honestly.
  10. At full load, the TWR with both linear aerospikes is 0.2....it crawls into orbit, but I get 1900 m/s out of the Shcramjets. It isn't designed to go exploring. However, I want to figure out a way to get down to Tellumo. Aerobreaking just doesn't work for spaceplanes on that god-forsaken planet.
  11. The Speedy McGoFast 6.587t / 3.387 Wet/Dry Get's into orbit with almost half the tank left. Not the smallest, but during ascent, briefly had a ballistic coefficient of 40mil+ (Highest I've ever seen). Docking port included.
  12. Megatanker 2: The Tankering 860t runway weight - 41k/49k units of LF/O to orbit
  13. 1.25m fairing will not explode due to Rapier thrust acceleration. You'd have to expose it to intense, re-entry speeds head on to cause a failure. The fairings are just that good.
  14. The best nosecone I've encountered is a 1.25m fairing tapered as slim as possible. It has high heat resistance and can be very aerodynamic. 2600K Max Heat vs Shock Cone 2400k as seen below.
