AdmiralDonSnider Posted February 22, 2013 Share Posted February 22, 2013 I figure your Ti material is a bit on the coarse side of things. Very fine Ti powder is best. And 10% seems plenty. 3% or even less I would guess is best. But others may help you with better input on both. Link to comment Share on other sites More sharing options...
DubaiAmateurRocketry Posted February 22, 2013 Share Posted February 22, 2013 around 5% is enough, Ti is not a good fuel, Aluminum would give better sparks. Link to comment Share on other sites More sharing options...
Col Posted February 22, 2013 Share Posted February 22, 2013 You only want it in the delay fuel above the spindle. Adding 10% of 50 mesh ti sponge will give you a nice white tail. Link to comment Share on other sites More sharing options...
ACLIGHTADDICTED Posted February 22, 2013 Author Share Posted February 22, 2013 Thanxs for the answers AdmiralDonSnider100-250um is betwenn 60to140mesh size this isnt really coarse in my opinion. DubayAmateurRocketryI ad the 100-250um sponge in my endburners after the spindle without any problems in addiction to milled BP ColSure, i will only ad ti above the spindle just in the delay so i think i will try it out with the 100-250um to see how it looks.

Mumbles Posted February 22, 2013 Share Posted February 22, 2013 I have no clue what DubaiAmateurRocketry is talking about. The aluminum will give no sparks what so ever. The titanium will be fine. You don't want the metal to be a good fuel. You want it to burn up in the air, not the motor. I'd go with the 100-350 micron stuff. I bet it will work great.
