We had a good solid launch with lots of youth groups (mostly Scouts and 4H). We had a couple of holds for aircraft, but the tower made up for it by letting us clear all of the rockets on the racks at 1 PM (our normal stop time) and the racks were pretty much completely full.
2015-03-19 General Membership Meeting Minutes
7:30 Dave Ramondi calls the meeting to order. In attendance is:
- Dave Ramondi
- Anthony Cooper
- Eric Melvil
- Ben
- Sheryl Cooper
- Paul Pittenger
- Robert Belknap
- Ari
- Stu Cobb
- Tim Robinson
- Fred Radford
Ari admitted the he forget to remove the ejection charge from the motor when he burned up a his glider at Snow Ranch. Ghost , punch out.
Tim Robinson bemoaned about his tree born rocket left a Snow Ranch.
7:45 Introductions complete. Launch permit secure for March. April will be up to Planetary Adventures. 2016 permit is in question due to hanger one proposed construction. Dave expressed concern over where LUNAR will fit in the future.
Proposed two Saturday launches in April. We have to wait for weather to evaluate fire danger.
Paul mentioned that he is assembling the competition launch tower. Need to get more participants for the NAR contest.
Ben Black Powderless Project. Ben did a presentation on how to fly as a Jr 1 without using black powder. He attempted to use servos to open hatches to deploy parachutes. He crashed his first attempt. Then used a servo as a sheer pin. Motor deployed the drogue parachute. Once the correct altitude was reached the servo turned pulling the pseudo sheer pin to gravity deploy the parachute. He has flown two successful dual deploy flights.
Paul talked about ways to compete in the NAR contest. They discussed what counted for scale rockets. Without the pink book being handy, they decided that a flying SR-71 didn’t count toward sport scale. There wasn’t one in Petter Alway’s rockets of the world.
Stu Cobb showed off his transparent rocket. He discovered that if you polished fiberglass enough, it becomes nearly transparent. Stu also demonstrated how to splice Kevlar rather than tying or gluing it.
9:00 Meeting adjourned.
Table of Flight Restrictions
This table is suppose to make it easier. You need to know your Gross Lift Off Weight (GLOW) and your motor(s) specifications. Start from the top left of the table and keep going down and right until you meet all the requirements. The last cell will tell you what you have to do to fly your rocket.
Launch site Dimensions and Distance to Launch Pad
This table is a combination of tables from the Model Rocketry handbook and the “Laws and Regulations for Transportation, Use and Storage of Fireworks in California”
Building your Estes Saturn V
History
This is a story about a BAR (Born Again Rocketeer) who as a child did not afford a Saturn V. This may seem funny but I worked in a Toy store from 1976 till 1979. That is what started my rocket career.
