May 2010 launch report (5/22/2010)

On Saturday, May 22nd, MASA held its fourth launch of 2010.  It was held at the sod fields near Nowthen.

This was a case of the weather forecast being completely wrong...

There were various special events planned for the day (Birdie drag race, HPR Cert Day, HPR "Smack-down").  Ultimately, none of them were able to happen.

The crew was on site at 8am to begin setting up the launch range.  The forecast had called for mostly-sunny skies with increasing winds out of the SSE.  In actuality, the skies were overcast, the air was damp, and the winds were light and variable.  The range opened for flying at 9am, and rockets immediately began taking to the skies.  A number of people started working on prepping for their planned cert flights.  About 10:30, a few rain drops began to fall.  The rain became steadier, the winds picked up, and there was lightning off in the distance.  At 11am, the launch was officially declared as done for the day.  Everyone scurried around in the rain, gathering up all the wet and muddy equipment, packing up their belongings, and heading home.  A few hours later, the sun and the stiff winds both finally appeared.

Oh well.  There will be nice days to fly rockets.  We just need to be patient.

A big thanks to everyone who got soaked and muddy picking up and packing up all the equipment!

A total of 36 flights were recorded on motors ranging from A to J.

A few of the flights:

Just wanted to say thanx for ALL the attention as I assembled my motor under Carol's pop-up canopy.
Seriously.
Really, I mean it.

I mean, where else can an "almost ready to launch to certify" guy go to have so much fun with so many fellow rocketeers under one canopy while still getting wet? :-)

I know there will be other days to certify and I'll eventually "get 'er done." Thanx for all the encouragement!

My neighbor Blake and his son Wyatt had a blast too, even though they didn't fly their rockets. Way impressed with the big-loud one.

Thanx to all that helped pick up the range in the rain (after the lightning had subsided).

We planned for a very limited time frame with windy conditions. Also the theme was odd-rocs. That naturally leads to the Art AppleWhite Collection in my case. Paul was burning up BP motors.

With the above in mind, Friday I loaded up various BP motors in the rockets. I also pre-assembled 4 AP RMS motors one F and 3 G's. This saves all that time on the field when you are counting seconds. I also had the Flight Cards made out at home, another time saver.

Saturday morning while checking the winds for the day we watched in surprise as a huge front moved across the Western MN border towards St Cloud with expectations of ELk River around 10:30+-.
We checked the email thinking this might be cancelled because of all that was riding on the Certs. before we drove up there.

Paul works nights so he loaded the car at 5:00. I was up at 6:00 and we were on the road at 7:25. Paul and I got there at 8:30 or so.

We immediately set up two pads for one controller. We leap frogged our flights back to back never missing a beat. ANd with the very excellent RSO/LCO job by Neal Higgins it went like clock work. The first 45-60 minutes we had the field all alone.

So here's Paul's tally.

1) Plastique Boink A8-3
2) FootBall Boink A10-3T  (Required flight)
3) Cato Rocket /Troll C6-0
4) Wacky Wiggler B6-4
5) Tri-Vor-Tex / Troll on a chute 3X A10-3T
6) Fun Noodle C6-3 you have to see it. Long Green Foam Noodle. It goes up with pop off fin cage and the foam floats back down He has it perfectly balanced so it comes down flat.

My tally.

1) Yellow Ultra-Delta Saucer - Infamous Quest D5-4. All Paper saucer arced over under thrust into ground. 4th try, one was ok. Very regressive motor not for high drag rockets. No more.
2) Hour Glass E9-4 Straight climb with tumble ascent at end burn.
3) The SnowFlake C6-3 a fair flight this time.
4) Stars & Stripes Original saucer F24-0W Best motor for this rocket.
5) Smiley on a G79-0W HPR Style 29/120 Big flame and lots of smoke to nice altitude. AeroBrake recovery.

Rain stopped A) 29mm Stealth (Qubit type) with rotation and tumble patterns on a G76-0G.
B) CINCO Saucer/Pyramid One of AppleWhites larger rockets. A G,H & I rocket 50Ns to 250Ns average motors. To be used with the AeroTech 38mm Special RAS G,H, & I motor.

I wanted to demonstrate the use of the 38RAS system. You need 3 hands. But a tube will help. Must be very careful that the O rings and fiber washers don't move while installing the spacers.

The totals were:  36 flights, 39 motors.  The cumulative total impulse was 1542 Ns with an average total impulse of something completely silly due to the single J motor completely skewing the curve...  The motor breakdown follows:
