Sneak Preview ...

Here is a sneak preview of the Polaron G2 rocket in the Phase 1 configuration. We decided to extend the rocket by another spliced quad for just over 21L of goodness.:) It's just on 3m long (~10 feet). When launched at 250psi, it will be the pyro equivalent of an H500.

Probably another two or three more days work is required before it's first test flight. Simulations for this rocket are looking quite good, and even more interesting for the boosted version. Though real life never quite agrees with the sims so we'll just have to fly it to see the actual performance.

Hey George

Very nice indeed your rockets are getting on an epic scale cant wait to see the launch report keep up the good work and your updates

Great work guys...

Hi George,

That is enormous! Cant wait to see how high that thing goes, it must break the 1000ft mark!

Regards Doug

Thanks guys, we are keen to fly it at the next opportunity, though there are a lot of firsts for us on this rocket so it will be interesting to see how it goes.... upwards hopefully. :)

Hi George,
Long time not check :)!
This is really big ! From photo looks around 3m/9-10ft!
Also from photo I guess that is with inside tube !? Is it?
A lot of impulse will be there!
Can you share some simulation data?

MariusD said...

Sorry, I looked at photo, and then
I read your post !:))
Lunched at 250 psi, with inside launch tube, if everything works
OK, it will be than 1200 ft.

that looks nice

Hi George
Simplicity and performance !!
Is it the secret ?

Excellent work ... But I have a doubt. The rocket body will not bend due to forces of rapid acceleration? He does not need some sort of reinforcement to prevent this? Sorry for English, I am Brazilian and I follow the development of you for so long.

Hi George,

It's HUGE.... Do you have a video of the chute eject? Won't the whole rocket break during takeoff? You must have an awful big car to fit that in... If it gets any bigger you'd need a school bus or something to get your gear to the launch site. I'm really anxious to see the launch! Will you stick in an onboard camera?

Take care!

Hi Ruben,

Sorry no video yet of the parachute eject. I will be putting together more information and videos now that I am back in town. :) Luckily the rocket disassembles thanks to the tornado couplings so we can actually fit it in the car. One of the main reasons why we continue to use them. But a dedicated rocket vehicle like a bus would be nice :)

The rocket will fly with a camera and altimeter. These will be located lower down on the rocket where there is space next to the tornado couplings. This should help protect them if the parachute deployment fails. I'm also hoping to fly another flight computer there as well to gather more flight data.

Hey George,

Just a quick thought, have you ever considered putting a g-meter onboard any of your flights?

Regards Doug

Hi Doug,

We have flown a friends flight computer on a number of flights and it measures acceleration, along with other parameters. We hope to fly it again on this rocket.
