We again
traveled to the launch site at Old National Pike Park, east of New
Market, for some testing and experimentation. It was a little
cool, but almost no wind, and no rain.
Objectives:
- Will the tube launcher pass
inspection by the NAR folks and will it work?
- Could we use a Big Daddy with weight
reduction and an E9 to get to 850 feet?
- We need to practice the Aerotech
motor launch process.
Lessons
- The tube launcher seems to work and
the safety officer gave it an OK.
- We can't load just any parts on the
tube launched rocket. We need to run a simulation with all the parts
assembled.
- It didn't look like the E9 got the
Big Daddy to even 800 feet.
- The Aerotech motor gave the Big
Daddy a good kick.
- With a short rocket like the Big
Daddy, we need to make sure the weight is in the center of the
tubes.
- You need to wear warm clothes when
it's cold.
