F10 Rocket Motor

Postby jack7gardiner » Sun Jan 20, 2019 7:57 pm

Hello,

I was just wondering where I could buy an apogee F10 motor.
If this is too hard in Australia, does anyone have any suggestions for other (relatively cheap) long burn 29mm engines?

Thanks,

Jack

Hi Jack,

I’m not aware of any 29mm motors with a burn time as long as the apogee F10. From my limited experience, that is an unusual motor.

What is the weight of your rocket?

As Brad said this is a unusual motor, with a very low average thrust you need to look carefully at the velocity of the rocket as it leaves the rod/rail. The rocket can easily be too heavy for the motor resulting in stability issues.

Thanks all for your replies!

That is quite unfortunate about the F10 :(

The reason I am looking for such a low thrust/long burn motor is it is for a thrust vector control rocket stabilisation system and I need this combination to properly test and calibrate the control systems.

If anyone has any suggestions for any other long burning low average thrust motors, I would be very appreciative!

Thanks,

Jack

Have you considered the Cesaroni range of ‘Mellow’ motors with burn times of about 4.5 seconds? There is a G33 with that type of propellant.

Another option is the F22 with about 3.1 seconds of thrust

https://ausrocketry.com.au/motors/reloa ... 22-7j.html

Here’s the link to the G33
https://ausrocketry.com.au/143g33-9a-m.html

Both aren’t listed in stock, might want to check with Blake, it’s posible they are actually available. Also you should talk to him about getting a special motor order imported. Although this will probably take some time, would be best in the long run.
