And considering that usually if you had a efficient enough ascent, time to AP is pretty big, wouldn't it make sense the have start value smaller than end value, by quite a lot? Maybe that could be the key on making a rocket avoid as much atmosphere drag as possible. Ohhh, thanks, this makes a whole lot more sense, its actual "time to apoapsis", I thought it had something to do with how much it held the angle before going prograde. (As we approach engine cutoff, the time to apoapsis will grow rapidly, but this is normal.) For instance, if Hold AP Start Time = 80 and Hold AP End Time = 50, the rocket will initially hold a time to apoapsis near 80 seconds and will gradually flatten out the trajectory and let the time to apoapsis decrease to 50 seconds near the end of the burn.
(Initially it will be less but once to hits 50 seconds, it will hold it.) If the start and end times are different, it will transition from the start time to the end time (I believe it is a linear transition, likely based on altitude). For instance, if "Hold AP Start Time" and "Hold AP End Time" are both 50 seconds, then the rocket will try to maintain a time to apoapsis of 50 seconds throughout the ascent. "Hold AP Start Time" is the time to apoapsis that the rocket maintains during the beginning of its ascent. "Turn Angle" it the initial pitch angle that the rocket rotates to when it starts its turn. "Start m/s" is the speed of your rocket when it begins its turn. (Initially it will be less but once it hits 50 seconds, it will hold it.) If the start and end times are different, it will transition from the start time to the end time (I believe it is a linear transition, likely based on altitude).
"Start m/s" is the speed of the rocket when it begins its turn. Thanks, is the turn angle the initial tumble angle? What I just don't get is the "Hold AP start time" supposed to mean. You want to keep it as shallow as you can and still make it to orbit. Of course a steeper trajectory is less efficient. If you want a steeper trajectory try some combination of the following: I change the numbers myself until I get something I like. I typically don't use the self-learn part of Gravity Turn. Also doesn't like it detects asparagus type staging (which is also more target for heavier launches).

It doesn't help that there is barely any explanation on how to fine the values if desired (besides the ? help which is pretty vague). ones with bad drag profile which you want to keep as little as possible in atmosphere.īasically its not good for when you want to specifically steep curves (lowering drag, using higher ISP engines).

Okay, this mod tends to result in rather shallow gravity turns which tend to work well for certain types of boosters, however it fails miserably for another certain type of craft: 1.
