Project Home
On Saturday, March 12, members from both teams traveled to the Great Meadow Virginia launch site for qualification flights. The day was partially cloudy, around 40 degrees, but little wind. We got off 7 flights. We used the site's launch rails. Objectives
- One qualification flight for the Red/White/Blue rocket at 400g with an E20-7.
- One qualification flight for the Pink rocket at 312g with an E12-6.
- Test the pink backup rocket.
Lessons
- The red rocket performed nicely for the two test flights, and the pink rocket performed nicely for the single test flight.
- The new pink rocket had nice altitude, bur a problem with the deployment of the chute. A fin broke and needs repair.
- The red rocket qualification flight had the chute and streamer tangled, finally deployed, but landed in a tree.
- The pink qualification flight had a problem with the altimeter (not turned on?).
- The official qualification flight was too heavy and did not reach a good altitude.
- No eggs broken and no lost rockets.
- We prepared the site's launch rail by cleaning, lubricating, and pointing with the wind. We used the same rail for all of the red rocket flights and the same for all the pink rocket flights.
- We need to do better for the final qualification flights.
