At last - a simple, inexpensive, good-quality pitot-static head for homebuilts! Thank you AC-S!
Good quality, works well for my application.
This particular design doesnt work well with the 230 airfoil. It doesnt seem to be low enough to get out of disturbed air. I get erratic and unreliable airspeed readings. Im going to switch to a mast type coming straight out of the leading edge.
The combined pitot-static looks just like the photo and appears that it should work fine for its intended application, but purchasers should beware that the welds are fairly ugly. They're fairly large, not symmetrical, and the heat-affected zone wasn't cleaned up. One of the welds is fairly close (1/4 behind) the single static port hole. Again, the port should work just fine, but I was expected a better fit and finish - every time I look at it, I want to grind the weld off and redo it (saving that effort was the entire point of buying this assembly). It'd be nice if they offered an option of buying the parts (two bent tubes, endcap, baseplate) unassembled, so that end users could put them together in a more aesthetically pleasing manner. For a low-stress application like this, I'm pretty sure the tubes could be held in place in the baseplate using industrial adhesive, and there was probably no need at all for the two tubes to be welded together at the bottom.
The distance from the flange mount to the L is fixed. The vendor has no record of any max airspeed data. It is an experimental part intended for small general aviation aircraft. No record of any failures due to airspeed.
This pitot tube is 1/4" OD.
Yes, two airspeed indicators can be run from one pitot tube. Please consult with your mechanic for correct installation.
The 15144 Pitot Static Tube is a 6060-T6 1/4in .035in wall alloy tube. It has an Inner Dimension of .180 in.
The four mounting holes are drilled and countersunk to use 1/8" diameter AN426 100* flush head rivets. The mounting holes are 1.1" center hole diameter.
The distance between the mounting flange and the elbow is 7 inches.
Yes, please see universal pitot tube cover part number 13-05610.
Yes but you would need to cut the other tube to accommodate it.
This could be mounted either way, this does not have specific mounting or application specs.
Per the manufacturer, the recommended PITOT tube is 11-11448.
