This means I don't need to use Spice in my BPlane module

Sorry I dropped out there for a moment. I was working on another project, which ultimately failed (see http://stkwans.blogspot.com/ for details) Anyway, I am currently working on two projects, one just a simple weekend endeavor, and one my long-term plan to change the very nature of launch...

A launch window for Mars opens once every 26 months, with the next one being in November 2011. While each window has better or worse alignment, all transfers are roughly the same in the most general sense. I don't see any reason to wait longer than 2013 or so. Pretend we have maximum budget...

New version 0.20 SideMountHLV :cheers:. Done just in time to keep the timestamp on the PDF documentation accurate. Major feature in this one is a programmable autopilot. Eventually I want to have the autopilot programmable from the custom 2D panel. So what's next? I don't know. Howbout you all...

Space Shuttle Main Engines are expensive. They cost something like $50M each, which is justified only by the fact that they are re-used. On a shuttle-derived heavy lifter, three of these are thrown in the ocean. So, I was looking into other hydrogen engines. We want hydrogen because we want...

New version 0.10 of SideMountHLV in the usual place. The documentation on the SDHLV says that it targets a 120x30 nautical mile (220x60km) insertion orbit. This is suspiciously similar to the space shuttle direct ascent orbit, which burns out at 109km altitude. This orbit has its perigee in the...

The next version of SDHLV is out, version 0.03. Run, don't walk, to OrbitHangar. I need to make up the 224 downloads I lost when I posted the update. :lol: I'm having fun with quoting things, as you may have noticed. A lot of projects out there have an unofficial title. For instance, Linux...

My vessel is fly-by-wire, meaning that the joystick controls a set of virtual thrusters which are read by GetAttitudeRotLevel( ) and then the vessel interprets this as a command and steers the main engines appropriately. The built in nav modes (killrot, prograde, etc) work, but not very well. I...

I volunteered to do DLL-based vessels, and the first request was for a Shuttle-Derived Heavy Lift Vehicle. This is on OrbitHangar now at SideMountHLV . It's still pretty basic, but it looks and flies about like it will. Do try it out. I was thinking that maybe we would want to do some updates...

UPDATE: Published at SideMountHLV The SDHLV is flying! If you launch a heavy-lift vehicle designed to take 100 tons of cargo with zero tons of cargo, you get a real hot-rod! This thing hit 12.5km/s at 10+ g's at main engine cutoff. It went that fast because it doesn't have a main engine...

A few more words about VesselMass. 1) It is not an MFD, a DLL, a library, or anything like that. It is a couple of C++ files you include in your project when you make your own vessel 2) Q: Why am I attaching airfoils, thrusters, and prop resources to your objects instead of directly to the...

I keep reading about a Weapons MFD. In particular it is mentioned in the Asteroids! addon, but doesn't seem to be included in it. I've searched the web from one end to the other by every means I know. Where is it? Is it really just a cosmic conspiracy?

Welcome to the Deep Space Test Range. St. Kwan's Home for the Terminally ADD has established this site for the purpose of testing addons in their native environment. Real rocket companies have to build elaborate test stands and test ranges, and when they are done, they still don't know that...

Well, all the core part of VesselMass is in place. The PegasusXL Mk2 works fine, and can put a payload in orbit from an air-launch point. VesselMass as a structure was more accreted than designed, and needs to be reviewed. I just added the parts that PegasusXL needed. The last thing to do is...

Well, I ran into a snag with VesselMass. ShiftCG( ) does quite a bit of the work I want, moving engines, meshes, viewpoints, etc. Airfoils can be done with EditAirfoil, and touchdown points with SetTouchdownPoints. With enough bookkeeping info, I can slide these things around myself (but it...

If you have ever looked through some plans or drawings of real aircraft or spacecraft, you will see what I will call station coordinates. Some point on the spacecraft, or maybe slightly in front of the spacecraft, is arbitrarily chosen as the coordinate system origin. All spacecraft structures...

Yeah, I'll describe my projects here. I like programming. Bird's gotta swim, fish gotta fly, I gotta program. Plus, half the addons on OrbitHangar require spacecraft.dll or multistage.dll, which aren't even on OrbitHangar. Nope, I'll make addons like :probe: intended it. Since Tuesday, I have...

I've been working on some code for a vessel to automatically manage the center of mass (CM). The idea is you build the vessel in "station coordinates", where you establish some origin not at the CM, then attach meshes, thrusters, airfoils, and masses to the vessel. The masses are my own...

I'm working on updating my Glideslope http://orbithangar.com/searchid.php?ID=2763 addon to among other things be able to read custom entry profiles (so you don't have to enter an XR5 on a Space Shuttle entry profile) and read the config files so that it finds all the runways in the world, not...

This is just a request for comment, and specifically neither a promise to perform any particular action nor a requirement that others do so. It is especially not a flame targeted at anyone. I was reading an interesting page http://www.joelonsoftware.com/uibook/fog0000000249.html talking about...
