Day 148 - Too Windy |
Date: 28th
June 2014
Location: Whalan Reserve, NSW, Australia
Conditions:
Overcast, high winds
>20km/h
Team Members at Event:
PK, GK,
Paul K, and John K. + Tom C. and Rod C,With family visiting
from overseas we took them to a launch although today we didn't
quite get to do a lot of flying due to the high wind conditions,
but we are including the launch report here for completeness. The
first launch was the regular Axion II rocket. We didn't put an
altimeter or camera on it as there was a chance we would not see
them again. The launcher guide rail was angled into the wind and
the rocket was pressurised to the normal 120psi. The launch went
well but with the parachute opening right at apogee it meant the
rocket drifted a long way down range. That helped convince some
of the other rocket fliers on the day to only fly low power
rockets. The rocket was safely recovered a couple hundred meters down range.
After waiting about an hour to see if the winds would die
down but without much luck we set up a smaller rocket with a
full bore nozzle and only pressurised the rocket to 90psi. We
also set the deploy delay about 1 second past apogee to open the
parachute later to also reduce drift. The flight went well and
rocket was recovered safely. With that we called it a day as the
wind was predicted to get even stronger later in the day. We
were happy to watch others fly their LPR model rockets.

There is no video this week as there really wasn't anything
worth editing - just rockets drifting off into the distance.

Although we haven't done many updates lately, we are
continuing with the development of the G2 rocket. We are
building a smaller reinforced rocket with reinforced boosters
that will test the launcher at the G2 pressures, but if
something goes wrong the smaller rocket will be easier to
repair.
Much of our time, however, has been spent on "another project"
:) for
the big Thunda Down Under 2015 event in March next year. This
event will be awesome. Most of the rocket guys from Australia
will be there as well as many fliers from the US, NZ and Europe.
With clearance to 60,000 feet there will be some spectacular
flights. As an example of one of the projects being flown is by
the guys in Victoria who are building
a full 1:1 scale V2
rocket. This alone will be worth the trip to see.
