2.0.8 Release
Spaceplanes at high altitude develop an altitude oscillation. This should smooth out flights in kerbin atmosphere.
Spaceplanes develop an altitude oscillation at high altitude. This should slow down the ascent pattern at high altitudes to stabilize higher altitude flight paths.
This reverts commit 18d256e.
Spaceplanes develop an altitude oscillation at high altitude. This should slow down the ascent pattern at high altitudes to stabilize higher altitude flight paths.
Changes to stabilize spaceplanes up to the upper edges of the atmosphere through the transition into space.
Replaced the old flight path controller code with 2 PID controllers (Pitch and Heading). Added more code to make takeoff and landing smoother and make sure the gear is down whenever it is coming close to landing (eg. in a manual landing scenario).
Changed how the spaceplane approaches the runway for landing and the yaw/roll parameters through decent and landing. Also undid the changes made to the PID controller and refined the PID values.
Implements possible permanent fixes for takeoff and landing.
Removed the ascent guidance controller and replaced it with dedicated PID controllers for pitch and roll. To smooth out the surface control movements, a low pass filter was implemented. A throttle control was also added to help with ascent and landing.
Aims the craft directly down the runway before touchdown, further stabilizing the craft. Also there are some throttle changes (and likely more to come).
Changed the throttle control to be more effective for craft that have smaller lift surfaces compared to their mass.
Added an additional low pass filter to reduce the noise coming out of the roll correction PID controller. Ideally, the input should be smoothed, but the noise was just too much for a single low pass filter to handle and much of the noise was originating from the roll control output.
PID settings now change based on a planes mass.
Added a yaw PID controller to further help smooth out the flight. Added some features to the low pass filters and implemented more of them through the roll/yaw control loop.
Tunes the PID controllers using estimated torques available from the control surfaces and the moment of inertia of the plane.
Should now be able to land on different planets surfaces, given more runways are added to the list in the future.
Vertical landing distance is now measured from the lowest point of the plane (hopefully being the landing gear)

Sorry, It seems I forgot your patch on the side of the road... Is this version your last one ? I can add it to the patch but I'll need some kind of "how to use". Each time I tried to use it my plane crashed :( |

Here is a simplified version of the spaceplane patch taking advantage of the changes made through Raf04 and Sarbian patches.
