Woot, great job Steve!
You may stage and cluster up to 10,240 newton-seconds (two L’s or single M equivalent)
Wow!!
Hi guys,
Here are some excellent pictures of my level 2 cert. flight.
Pictures were taken by Ray LaPanse. Thanks again, Ray
Which motor was that? Lots of mach diamonds! I saw a lot of them on my I216 boost – Ray caught that as well. It is great to have him out there!
Wow. That looks awesome.
Wow, great pictures, Ray!
MACH DIAMONDS 😯
8) It should look familiar. The I216 is a J285 with a Smoki Sam nozzle. That Dr.J what a tricky fellow! 😆
You will never see a mach diamond. I like the black smoke, but there is this issue ;-0
These mach diamonds were really cool.
Hi everyone,
Little Blue Dawg, had its third flight last weekend, 7.11.10 THought i’d share my stats.
Motor= J420-1008 CTI 38mm 6grain xl
Rocket weight= 3.4lbs no motor
Axial Gs off the pad= 28.81
Max Gs= 72.74 Wow that .6 gram main charge is still maybe too strong.
Motor Ignition time (sec)= 0.125 seems fast to me.
Temperature (F) 98.13 Man thats one hot rocket.
Altitude= 10,868′ New personal best. 2 mile club, woot.
Velocity (Accel-ft/sec)=1098
Velocity (accel-MPH)=749 Almost the speed of sound
Congrats on the two mile club. That was a gorgeous flight. 😀
As for the motor ignition time, you can safely ignore it. The Raven in my M1939 shot on Sunday said it had an ignition time of 0.645 seconds, which was definitely incorrect (I used thermite, and it was absolutely instant on). I think that is just looking at the length of the buffer prior to liftoff detection, which is not really correlated with the ignition time at all.
We are Good to Go with our scheduled and approved launch on Saturday April 5th and Sunday April 6th, from the North Site, subject to change – Mostly cloudy and High Winds predicted. Range and waiver should be active by 9AM on Saturday. The Pawnee National Grassland remains fragile and dry, so extra precautions are in order. Please stay on the authorized roads and please don’t park more than 100’ off the road at the flight line.
