I'm alive and well, thank you! I have abandoned the project, the design is almost done but I realized there's very little chance of actually building it given my personal and financial situation. You should check Totalitor's youtube channel (I'm a subscriber) for your DIY liquid fueled rocketry needs :)

I think I really got when i designed a real rocket engine was able to rendezvous and dock. The universe became my playground then. Before that I was limited by single launch mass.

No the rocket. Personal issues, which I'd rather not discuss in a public forum. I hope you can understand.

Yes, the project is still very much alive! It's just that I have some very complicated real life responsabilities and issues that prevent me from having free time, taking my notes and blueprints and making them into a good quality article. Also i've ran into some legal trouble and I'm pretty broke, so there really is no money to continue the hardware build in these days. But rest assured, this will be completed if it takes me 20 years!

Yeah sorry. My ISP is driving me crazy with microcuts

Wageera Aerospace, the same people who brought you the Kearjet Bussines/Leisure Jet, have the pleasure of bringing you a new design: The N2 Personal Shuttle is a SSTO spaceplane, designed to carry 1 crew plus baggage to orbit or to a space station and back in a safe and economical fashion. It is an excellent spacecraft for pilots seeking the challenge of precision flying and the ultimate in speed, and for space programs in need of a cheap way to level up their pilots, and bring science and crew to space stations and back. This spacecraft can reach anywhere on Kerbin either via long-range atmospheric cruise or a faster suborbital hop, and will always achieve orbit safely and with margin to spare as long as you follow the instructions provided here. In most cases, even if you somehow have managed to run out of fuel during climb, as long as your apoapsis at the time is at or near 65 km, and your speed is above 2 km/s you will be able to limp into orbit with the translation RCS system only. The amount of ΔV remaining after orbital insertion will depend heavily on the launch profile used and the parameters of the target orbit but the best we’ve seen in testing is 347 m/s ΔV remaining when inserted to a circular equatorial 71 km orbit. The usual ΔV remaining after inserting into a 100km circular equatorial orbit is about 300 m/s ΔV plus about 600 kg of monopropellant, wich is more than enough to perform a rendezvous and dock to a refuel station with very wide margins of safety. After refueling in orbit, you can get up to 1.44 km/s ΔV. A typical cruise speed in atmosphere is about 1300 m/s (Mach 4.4) at 26 km altitude. Basic capabilities: Stability: Very stable in all regimes, up to and including hypersonic reentry. Just trim it as needed and it will fly hands-off, no SAS required. Stalls: Due to its mixed canard/elevon design, this spacecraft will not stall, but, upon reaching critical angle of attack, pitch authority will be lost, and the nose will drop, with no tendency to drop a wing as long as reasonable yaw angles are maintained. Stall recovery is the same as in a normal aircraft, but be conscious that it will take more height to recover. Achieving the critical angle of attack is almost impossible whenever full power is applied. Other unusual attitudes: For all tested anormal pitch, roll and yaw attitudes at speeds below Mach 1, centering all controls will result in either immediate self-stabilization or a mild dive from which you can then recover by slightly increasing pitch. Anormal attitudes above Mach 1 were not tested, due to the obvious risk, but our best guesses engineering models indicate that the spacecraft should recover in the same way. Aerobatics: The N2 was not designed to perform aerobatics, and consequently pitch and yaw are too sluggish for aerobatics, but it still can do cool aileron rolls and barrel rolls with ease. Variants: The plane comes in two variants, fully fueled, and jet fuel only, so you can easily fly a lighter, higher performance model for short hops that do not require oxidizer or monopropellant, without having to waste time manually editing fuel tank levels and worrying about potential center of mass issues. Included in your download, in classic Wageera Aerospace style, is a VERY comprehensive Pilot's Handbook with everything you might ever need to take the N2 Spaceplane to orbit and back.

Working on 1.2, excellent for my miniature Space Shuttle. Thanks

It doesn't help. There is a large amount of individual operations required, but most of them are performed during flight planning and consist of simple addition/substracion/multiplication/division, rule of three, etc. Once in the air the amount of math is little and you have an electronic or mechanical calculator to help you. Also most of the time absolute precision is not a crucial requeriment, so rules of thumb and approximations work fine.

Thank you for choosing my project! It is taking WAY longer than expected, unfortunately real life issues have kept me away from the project these last months, but my motivation is still sky-high and can't wait to resume work in my liquid fuel engine!

That was exactly my tought process during most of the design, I have a pretty low math skill so this was a real challenge, but I also learned a ton.

That would be absolutely awesome. Right now the project is halted due to real life issues on my part, but rest assured I'm still highly motivated to finish it! I've learned a ton from what I've done so far, and am really looking forward to being able to continue the process. If you need 3D data, I can provide you with the CAD files.

If anything else, it should work as a whistle! (Puns aside, yes, it is difficult to build in such a small scale)

At that scale i'm guessing it makes no difference.

The numbers still work out somewhat but it's difficult fabricating on such a small scale I'd say fire this one, see what it does, then build a bigger one (10 pounds is about the absolute minimum without having to involve precision machining and the hassle and expense that goes with it.
