Mach + Nosecones

SDramstad said:

Up until now I have been using the cheap polypropylene nosecones and they have worked great for what I have been doing. But now I am looking to do some high speed launches and was wondering just how much speed will one of those take? I know Wildman has 2 new high speed nose cones but they only come in 38mm and 54mm. Was looking for something to fit a 2.6 inch body tube. What have you been using?

Madcow has fiberglass 2.6 in nosecones. I am sure that these would be fine. A 2.6 inch rocket will probably not be mach 1 for long. I am sure the LOC 2.6 inch plastic cones would be fine also. Lighter than fiberglass.

I have the same question as the initial poster. I am looking at making a 38mm Min Dia rocket with Loc tubing and NC. When I put a 3 grain Vmax (I800) into OR, it says Mach 1.84 (this is before I add the electronics, chutes, etc), but regardless, it will definitely blow past the transonic range. Is there where I need to start building with more exotic materials?

You may want to look at CTI's glass-filled polycarbonate nose cones. They are good for Mach 2+ (without a tip). Looks like they should fit LOC's tubing. If not, they can be machined. Any ProX dealer can order these from us. Rocketry Warehouse also carries these.
