Smart General Ascent Program
SmartGAP Vizzy Automated Launching Program with Moon Orbital Plane detection, Version Alpha 2
I am developing this in the Solar System, but it works in the Juno stock system as well (I hope).
The launcher program is able to first wait for reaching the Moon Orbital Plane (if the launch site ever passes it, I use Kourou, Guiana with Hyperpatchs Solar System 2).
Then the program launches the rocket first vertically, then initial pitching and then going into a gravity turn which is adapted during flight to reach a circular orbit finally. Boosters are supported.
In this verision the Moon Orbital Plane function has been deactivated in the User initialization section with Variable bWaitForMoonOrbitalPlane set to False as default now.
The general problem I have is that the Vizzy program does not have information about the next stage but only about the current one. Between other things it means that the rocket must have a somewhat not so bad design.
Most work has been done in this version for the overshoot treatment (if Apoapsis is reached too early) and the final vertical speed anhilation with RCS.
Main differences between version Alpha2 and version Alpha1 :
* Waiting Boosters to come down for additional 4s
* Introducing Initial Pitch Velocity Ratio for a reliable initial pitching
* Introducing variable OrbitStageMinTWR for better overshoot avoidance (making sure your orbiting stage has that TWR even it is not strictly neccessary)
* Increases AoA in dependence of OrbitStageMinTWR when v > 0.5 vOrbitMax
* Brake to orbiting(type 2) is only allowed if v > 0.85 vOrbitMax (former: 0.5) leading to longer staying in the AoA control phase
* Increase fine thrusting factor shortly before reaching Apo from 1.1 to 2 (for better thrust startup time consideration)
* Overshooting treatment changed. Now accelerating vehicle to stationary APO velocity at overshooting begin
* Anhilating vertical speed with main engine or with RCS when only small changes are needed for finalization
TODO
* one day this should work for every rocket generally beeing able to reach a stable orbit.
* become even smarter
Demonstrator craft here is the Mars 4T rocket with 40t space station core element.
Your feedback is greatly appreciated ! Please help me to improve.
Especially TESTING your own rockets would help me a lot !!!
