Orbital Science Corporation's Pegasus XL launch vehicle has to deal with a lot of the problems which have been discussed in this thread. I am modeling it, and have had some practice flying it. First off, it has wings. The sole reason it has wings is that it is launched horizontal, and needs...

Mars, because the default scenarios with the DeltaGlider all seem to be on March 14, 2001, which is during a launch window to Mars. You can get there with about +2300 prograde, +2000 out, and +300 plane change on TransX.

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...

Boeing 737,747,757,777 (and maybe others) Airbus 319 (and maybe others) McDonnell Douglas DC-10 US Air Force C-5, E-3 (Just on the ground) Diamond DA-20 Katana (I actually flew it) de Havilland DHC-8 Dash 8 Tupolev TU-134 - Maybe the most fun airliner I have ever been on. It sure looked like a...

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...

Also, a gram should be the mass of one liter of water, and one meter should be the length of the side of a liter cube. And why is the fundamental unit of time, the primary base of all our measurements, and the thing we can measure the best, called the second? Why not first?

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...

Friends don't let Friends fly at orbital speeds through an atmosphere... :lol:

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 love to write code. Someone come up with the meshes, I'll write the DLLs.

*Write code for any custom ships that are needed *Launch from Earth Surface to trans-Mars injection

The Apollo guidance system was originally designed with just such a out-of-contact scenario in mind - not from some onboard failure like Apollo 13, but from active jamming by the Soviets. Remember that this was the space race, part of the Cold War. The system was originally designed so that...

ICBM reentry vehicles are relatively low-drag, compared to any normal spacecraft we in the Orbiter community may be used to flying. Because they are weapons, and because they don't want to be shot down, these reentry vehicles are designed not to hit terminal velocity before the weapon is...

The sun can be north of you anywhere in the northern hemisphere, near sunrise and sunset. For all of the following, I presume you are in the northern hemisphere. At the equinoxes, the sun rises at due east and sets at due west anywhere in the world, except exactly at the poles where due east...

The last version I worked on (I think) detected every runway in the world. It reads the Earth.cfg file to find all the runways. I know I did that, I'm just not sure if the Orbithangar version has that. By the way, the primary purpose of glideslope is to do reentry corridor management for a...

There's the glideslope MFD that I put together some time ago which has a HAC mode. You probably want to do things like customize the size and displacement, which it can't do yet, but the code for it is there also, if you want to take a hac at it. Look for it on orbithangar.

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...

Malware warning!!! That'll learn me to use IE for anything.:dynamite: I tried to download the file from the givem Megaupload link, and it didn't work in Firefox. It crashed immediately, then crashed again immediately when I did the usual firefox recovery thing. My copy of firefox crashes a lot...

I think I've seen this problem with DGIV but only in one limited circumstance: The flow rate (and Isp) before starting the engine as shown in BTC is different from what is shown in the cockpit indicator after startup, but as soon as the engine lights, BTC has the correct value. This is because...

I just tried out the Delta4H myself and found out that it has its own autopilot. On a fresh Orbiter install with no PEG, I launched it once and had to pull up constantly to get it to fly straight, and once I let up on the stick, the vehicle nosedived like you explained. The next time I flew it...
