Bet your pleased at the results.
All the best |
Hi Andy
We were impacting at 310 metre/second so we had to design for up to 40,000g We actually recorded 20,000g at the tail during the impact and slightly less at the nose. You may have noticed that they didn't fly level but hit with a nose up attitude. This created quite a high lateral loading at the back end which distorted the tail of the penetrator quite nicely.
All the electronics and batteries actually survived fine and still work now! maybe we over engineered it.
The real moon versions will have to survive for a year after the impact so they need to be quite well made.
