No not annoying really.

I wasn't expecting to get feedback so quickly but that's ok and appreciated.

I just wait for the first bug to appear while a new installation script is running for tests, I am deeply bored watching another setup.exe getting called again and again.

This is what I have so far for the airship screen, i.e. the big MFD:

Left indicator bar is ballast change, next indicator is for the gauge pressure and the next indicator is the apparent vertical force on the airship calculated from vertical acceleration and mass. This is useful for balancing the vertical forces to zero and helping to keep altitude constant when adjusting the ballast, gauge pressure or aerodynamic forces.

The airship diagram bottom right shows buoyancy, weight, ballonet size and landing gear status.

The top right diagram shows direction of thrust. Top horizontal bars indicate engine thrust (top) and fuel remaining.

Thanks, I was thinking it looked similar to the graphics of a 1980s 8-bit home computer ...

Well, just look at the Zeppelin NT for comparison...

I have uploaded the latest version to post #1.

I'm still working on the base building side of the addon. The buildings are not included in this version.

Also cargo transport in general needs a bit more thought, i.e. perhaps adding a crane.

I haven't really thought how it would be transported to different planets. I am wondering if it could be launched into orbit in a stowed configuration, travel to the planet and then inflate its envelope and deploy its fins and wings before entering the atmosphere. If it can't enter inflated then it'll have to be inflated and reconfigured during the descent or on the surface.

Well, for Mars, the plan is to use vacuum blimbs, since the pressure difference is so low. Those are supposed to be inflated in the sense of inflating narrow struts and rings around the vacuum, or be assembled from smaller rigid elements brought from Earth.

See here for a overview poster for Mars:

Thanks that looks interesting.

btw I have included the newest C++ code in the latest version addon. I have commented it the best as I can.

It's magnificent, but I think there are a few bugs that I need to check on if I get time...

Could you please explain how PAYLOAD and BALLAST scenario parameters are being used to size the airship, or why PAYLOAD does not get added to the total mass?

Also, I saw a condition in which the lifting gas had lower pressure than the atmosphere. That shouldn't happen on earth with a helium airship.

The airship is sized so the airship has neutral buoyancy and zero ballonet volume at its pressure ceiling altitude. Ballast and payload mass from the scenario are used for this calculation. Payload mass isn't added to the actual airship because I've assumed the payload will be something attached via the docking port.

Yes the gauge pressure goes negative but it's not supposed to. I'll fix that.

Thanks for testing it.

I think I've figured our how to deliver the airship to different places in the Solar System and make it fun. The basic idea is that the airship is delivered in cargo boxes and then assembled at the destination with the press of a key.

However for the airship to assemble itself the correctly, i.e. spawn the vehicle, the correct number of cargo boxes required will need to be delivered. The number of boxes will depend on the assembled mass of the airship. A large airship requiring more boxes than a smaller airship. The boxes will also have to be placed in close vicinity to each other for the airship to assemble itself.

I will use my DRM 1 cargo lander to test out the idea. I think it might be quite fun as some precision landing may be required if more than one lander has to be used to deliver the cargo boxes.

Could your code also work for simulating a vacuum airship on Mars?

I don't see why not. A basic approach could be to set the lifting gas mass and the structural masses could be set from the scenario file. Then by setting the lifting gas mass to zero you could have a vacuum airship. Mmm I wonder if it's really that easy. I can check if you like.
