Fantom on a H170 Sparky

One of our members in Thailand has sent me a report on his recent visit to Yasothon in Thailand.  icon_thumleft Would like to share this experience with the Australian Rocket Community! Photos and videos will follow when have sorted these out! Many thanks Mick G!  icon_thumleft Would love to go to this event!  bltongue

Sawasdee krub, jak pratet Tai.
( hello from Thailand )

From 9.5.2014 to 11.5.2014,  I was in Yasothon 500kms N/east of Bangkok for the " Bang Fai festival ". Saturday was a big parade through the main street. This included traditional "Ram Thai"  dancing and many groups from individual districts in this N/eastern Province with their "rockets".
Sunday was the launch day.
Approximately 10,000 people were there to see the launches.

The Bang Fai are similar to sky rocket fireworks....
The big rocket motors are made from 125mm dia plastic pipe and are anywhere from 1m to 3.5m in length. With a 3m up to 10m bamboo stability "pole" attached with fence wire and packing tape.
Very basic. No fin's. No electronics. No recovery parachute but AWESOME power.
L to P in equivalent N/Seconds with long burn time's.
The motors are not A/P or B/P.. but are a core burner, hand made propellant... I know what they were using but will not Elaborate any more out of Safety reasons...

A crew of 8 prepare the Bang Fai on the launch towers. ( 6 towers. 4 small and 2 big towers )
The Bang Fai are hoisted up with rope and then held in a metal cradle for guidance with a chain underneath to hold in position and also strapped and tied with "vine" to the towers...
Ignition is electric with a "ball igniter" on a long thin bamboo pole.

Bang Fai launch ;
Wow.......
There is No countdown just fireworks start going off then the Bang Fai is ignited...
They sit in the cradle from 2-5 seconds while the motor comes up to full power before they launch. Very, Very loud roar and smoky..
Some fly straight and reach very high altitude. Some corkscrew. And a few cruise missiles like flights.
There was about 30 big Bang Fai launched throughout the day with many smaller launches also.

I had a great day. The Thai "Bang Fai- eer's" are very friendly and like to show foreigner's their Rocket designs.

A few words of warning-
#There is no safety distances at the launch site.
#No crowd control.
#No air clearance.
#only a few "danger zone" signs in prep tent area.
#very hot temperature. 35°c with 60% humidity.
Also I would Not like to be down range where the Bang Fai are landing. Some Ballistic impacts were seen.

But it is A must see event for anyone who loves rocketry.
I hope to see some AARC or ARA members here next year.. I will be there for sure.

Keep flying high and Safe....
Your A.A.R.C and ARA member/ resident of Thailand
Michael Gerlach.

P.s Many Thanks to Maurice Laffin who posted this on the ARA website for me.
Cheers mate.
