3D CAD Complete!

A project log for ADC-Probe

The ultimate airspeed sensor - a mini air data computer inside a pitot-static probe!

I've finally complete 3D models for the ADC-Probe. After several rough drafts, I decided to go with a simple aerofoil shape instead of a probe. I found the whole assembly can be made much smaller and lighter this way. This image shows the assembled probe with both pitot and static air pressure ports. This design is only 34mm high and about 40mm long.

The probe is divided into two 3D printable parts. The top part will contain the pitot pressure sensor. This pressure sensor will be mounted on a PCB that measures only 5x10mm. The wiring will go through the hole in the center of the lower part to the main PCB. The hole will then be sealed up with epoxy putty (or something).

Pitot air will enter through the hole in the front of the probe. Static air will be free to move through the port on top. The peg hanging off the upper part is hollow and static air is free to travel through it to the main PCB.

The two parts will be glued and sealed with RTV silicone thinned with toluene.

Time to print a prototype I think!
