Altimeters in Saucers

[cavecentral]

Building my first saucer and it is too heavy to let free fall. About 5 to 6 pounds finished.

Anyways, I am attaching a strattologger to the bottem for chute deployment (apogee only). I'm sure I need to house the altimeter with vent holes in some manner. Any suggestions? Not sure what the pressure ranges are on the bottom of a base drag rocket.

Plan to build a little 'box around the electonics with the standard 1/4" holes I use in my normal AV bays. Just want to see what others have done that worked (or didn't).

Thanks,

This is my large saucer. The 2 pods next to the motor house altimeters and parachutes. The altimeters are set to deploy at 250' on the way back down, no apogee event. I use long burn motors that may still be burning as the saucer arcs over at apogee. The chutes deploy out the bottom of the saucer.
You do need to get the chutes away from the saucer or they tend to suck into the recirculation under the base of the saucer.

As our LCO would say, what a wonderful waste of propellant!

Thanks. I plan to shoot the chute straight backwards out the bottom of the saucer. Mine doesn't have free space around the motor tube to do what you did for altimeters. I'll have mine stuck on the bottom with some shielding from wind and hope for the best.
