Final Motor Choice ,[object Object],[object Object],648.4053 101.0944 Altitude (m) Velocity (m/s) Max Values

J250 Thrust Curve The thrust curve is still quite smooth despite it’s short burn time J250 thrust curve J115 thrust curve

The Running Order (a) (b) ,[object Object],[object Object],Sliding the rocket onto the launch rail

Crash Analysis The recovered rocket ,[object Object],[object Object]

Results ,[object Object],[object Object],[object Object],We used Newton’s laws to roughly calculate height Error = 0.606% h max = 644.4768 m h max = 648.4053 m v av = 50.5472 m/s v max = 101.0944 m/s v max = same as predicted t total = 24 s t total = 25.5s Predicted Flight Actual flight

What Went Wrong? Apart from speculation on the day, I did some detective work on the internet regarding the software afterwards We launched on 06/03/2005, so we were probably running V3.6
