THE NEW ROCKET PARTS ARE HERE! THE NEW ROCKET PARTS ARE HERE! I REALLY AM A STEELY EYED MISSILE MAN!
For CAing a cone, you hold it by the shoulder (with gloves), tip pointing down, and drizzle the ultra thin CA down the side until the whole surface is saturated. K'Tesh wrote a good tutorial.
I've had problems getting it smooth during sanding, and so for my latest build I put thinned CWF over the sanded CA (suggested by someone around here but I can't remember who). Looks good so far, painting in progress.
This is starting to look really cool.
IMO, the BT-80 is the flimsy part. The struts should be fine. Might be worth reinforcing a bit so it won't get dented like a pop can.
Insufficient data. For GD stabalization there is experimental data on which the D2 rule is determined. Venting olny to avoid Krushnic is a wholly different case and requires wholly different data. I don't have any such data, which certainly doesn't mean that no one else does. But any GD realted rules are entirely irrelevant.Since the purpose of the inlets is for air flow rather than stabilization, do I need the full D squared inlet area?
How much area to avoid thrust reduction is a good question. I have now made 4 successful GDS rockets and all experienced some level of Krushnic.
