Automated Circular Interplanetary Transfer - v1.1

Zero inclination means an equatorial orbit. ( also assuming no axial tilt, which was standard for SR2 planets last I checked)

@sflanker what exactly does “zero inclination” mean

@Playery this flight program does not use activation groups. Instead it waits for you to set your target to a planetary body that is orbiting Juno. I have another variant that has an activation group for each planet in the base solar system, but I haven't uploaded yet because I've been trying to fix a lingering bug. This flight program is not exactly a plug and play script like some others. It is mean to be a proof of concept for those learning about orbital mechanics.

@sflanker oh ok, I was curious as to why the program just stopped before I even reached Tydos. I’ve still got a lot to learn about getting into planetary orbits. Every time I tried to get into Tydos’s orbit I would shoot right past. I’ll probably figure it out eventually.

@Halodoublej sorry, forgot to click reply. See response below. Also, just FYI, this is meant more of a proof of concept of the math than to be a user friendly utility.

Yes, this program warps to the next available departure window, then warps to the ideal burn position and executes a single burn to exit your current SOI and get on a transfer orbit to your destination. It will then display "en route to _" and go back to it's initial state. It does not perform inclination correction burns or capture burns. That is left up to you.

Is the program supposed to end once you leave Droo’s orbit and begin to travel towards (for example) Tydos?

@Halodoublej This flight program is designed to be used on a rocket after it has gotten to a circular orbit with zero inclination. So you'll need to build a rocket capable of making orbit and use a separate flight program to automate the launch. Kell Auto Launch is a popular option. I have my own auto-launch script but it may not be as easy to use as Kelly's.

I’m very new to this game I downloaded this cause I want an orbit around Tydos and Urados. My rocket doesn’t want to even lift off the pad. Is it a problem on my part?

Yeah, I'm not sure what would cause that but it is probably a small discrepancy between the predicted velocity after the SOI transition and the actual velocity computed at that time. In my testing it hasn't made a huge difference.

One thing I noticed is that the after you leave the SOI of a planet your orbit path changes. I haven’t really thoroughly tested it on this or the other version, but it happens with all my other crafts. It might happen here is all I’m saying. I think it’s a glitch. @sflanker

Awesome :3

Known Issue: transfers from Tydos to inner planets miss rendezvous by ~1-2 days, even after making a manual inclination correction burn. I'm not yet sure why this is happening.

I have only tested this flight program on transfers from Droo to Cylero and Tydos and vice versa, and only with this craft. However, this should work for other vehicles and for other transfers, so long as the vehicle has sufficient delta-v and enough thrust to make the necessary burn in a timely fashion.

Assistance in testing this with other vehicles and transfers would be appreciated. Remember that your starting orbit must be circular and have zero inclination. If you encounter a failure I would love to know the following: 1) mass/delta-v/Isp/Thrust stats for your craft, 2) your initial orbit parameters (origin planet and SMA), 3) your target planet, and 4) the nature of the failure (apoapsis too high, to low, burn up in the atmosphere of your starting planet, etc).
