Hi there people.
First of all, did this forum change or something? I am pretty sure I already had an account at orbiter´s official forum, but even the inteface of this one is different from the one I remember!fftopic:sorry! hehe.
Well, going to my point. After 2 years of trying to get acquainted to orbiter and things I thought that today I had finally gotten the point of hollman transfers. So, I started out my delta glider at Cape Canaveral (that scenario that comes together with Delta Glider IV to launch to ISS).
I changed the map view as to intercept a launch window to the moon, so I had to use time warp to fast forward almost a day in advance in order to get to my desired launch window.
So, launch window approached, relative inclination pretty close to zero, take-off.
as soon as I reached LEO, I performed a correction for my RInc wasn't all that pretty. After RInc correction, turned prograde and started to tune my transfer MDF.
I followed everything according to the rule. My delta V got somewhere around 3.100, fixed my Ejection point, everything correct.
Time to burn was fine, burned as correct as possible, quit my burn when DV was down to zero.
But when I finished the entire process, I figured out that the moon was opposited to me. I was going somewhere else other than the moon!
I got sooo frustrated! because it was the first time in two years I was sure the transfer MDF was correctly tuned and that I followed everything as I should.
What went wrong!??? Wasn't I supposed to get that scenario and fast-forward for the launching window? do I have to only use that scenario that comes in the tutorial? what if I do not want to use the older delta glider? what if I want to go to the moon somewhere closer to today's date?
If it was fine, what was wrong? the transfer MDF told me the burn ejection time, the map told me the launch window, I only took off when both lines at the map where together and my RInc was close to zero.
Another question. How come every single time I try to perform a transfer, when the delta glider is on its way to the moon and I timewarp, it spins??
It does not fligh pointing straight ahead as in the tutorial? what is wrong? I always use prograde until the burn ejection time, but when it's ejection time, I turn off prograde, so I figure it should be pointing straight ahead and not spin around.
Sorry for all those questions. I confess that I am a little frustrated, it's been two years that I have been trying to to that but no success! I can use flight simulator to fly from airport to airport using the VORs, ILSs, waypoints and sheets, but I cannot figure this thing out.
With two kids and a job to cope with, it probably gets hard to focus on the white papers to learn it correctly, but I am trying as hard as I can. If you guys give me a hand on this one, I will appreciante it a lot!
Thanks a lot!
