As I understand, Solar Sail runs on dual energy: light pressure and solar wind. While the former is quite deterministic and rigidly following calculations, solar flares create huge bursts of solar wind - at unpredictable points in time, of unpredictable intensity.
How would they affect solar sail propulsion?
- solar sail needs to be huge and light - that means quite fragile. Would it be possible they could damage (tear) it?
- even if it withstands them physically, wouldn't they throw the craft off painstakingly calculated trajectory?
- anything else I missed?
(and generally, what is the proportion between "propulsive power" between the two accelerating factors of solar sail?)
