Model Rocketry with Faith Community Church, 2015, Part II

While one can launch very small rockets in some of the parks in the Philadelphia suburbs, we had to drive a bit to launch most of what the kids helped us build. We attended a weekend launch at the Philadelphia Area Rocketry Association, PARA 521. These are done from a large corn field north of Plumsteadville.

We have been to at least seven launches at PARA during the last ten years. They are a friendly bunch. Often a group from Civil Air Patrol or the Boy Scouts will be there, too.

We showed the kids how to mount the motors, prepare the parachutes or streamers, and then to prepare the electrical igniters. The older ones did all the work on their rockets. We helped the younger ones a bit.

There were quite a few rockets launched that day. Most used the small Estes motors that are based on black powder. A few of the bigger ones used AeroTech or Estes motors that burn a black rubbery solid similar to what was used in the solid rocket boosters of the space shuttle.

On a side note - it is hard for us to believe that the space shuttle is no more. Heidi and I grew up when it was science's newest triumph. Now we watch the Space X rockets that can land and be reused. Times do change!

Weighing a rocket, 2015

PARA, and the National Association of Rocketry, have strict safety rules. Do not let the laid-back demeanor of the Range Safety Officer fool you...

Launch pads, with glider ready to go, 2015

There were multi-stage rockets, a rocket with a glider, and yes, Romily's egg launcher. Model rockets are inexpensive and simple, but they still have a lot of variety.

6 rockets on the pad, 2015

Note - Romily's egg made it back to the ground unscathed. She was thrilled.

We launched eight rockets and got back all eight. One lost a piece. A second separated from its streamer, resulting in two fins getting torn off because it landed harder than it should have. We think we did pretty well.

The big blue and yellow rocket was on a G40 motor. It was the first time Kevin had launched a motor larger than an E9. It flew perfectly. It was also very loud. Most of the kids liked that, but the youngest one got a little scared. Note to self...

Happy kids with rockets, 2015

We think everyone had a great time. It was a shorter time that it might have been because the launch was on a Sunday. Our group attended church and then drove out to the site. The result was that Kevin was hard pressed to help all the kids get their rockets launched in the time available, but the folks from PARA decided to stay a little long into the afternoon, anyway.
