Hello everyone,
I'm reverse engineering a latch that is used on a "blow out" door of a turbine engine thrust reverser. I like to know exactly what the part's function is, but I'm stumped here. What exactly is the function of this blow out door? Does it simply alleviate an overpressure in the...
Hello all,
I'm not a rubber or seal expert - my experience with these are quite elementary. I apologize in advance for any really dumb questions.
My company is Reverse Engineering a Back up Seal for an aircraft application. The material appears to be a green viton by virtue of the packaging...
Hello All,
I am Reverse Engineering two aircraft fasteners that have me thrown for a loop because the materials are not US-type HSLA steels.
The first is a 30NCD16 steel that is 180-200KSI in the H & T condition. The only specs I can find on this material are prEN2478 and prEN2137. Is anyone...
Can anyone recommend a good reference for design of closed centrifugal impellers? We are reverse engineering a closed impeller for an aerospace fuel pump, and would like to optimize the design to reduce vibration.
Does anyone know if the reference listed in the Pump Engineering FAQ has a good...
Hi everyone,
I read recently that nickel alloys formed or machined with steel tools can have ferrous material smeared or impregnated into the surface. This material, of course, can oxidize when exposed to high temperatures. Is there a common surface conditioning or 'passivation' spec that is...
Hello everyone,
My company is reverse engineering a turbine engine component that consists of a small plate onto which two bolts are welded. The plate is most probably Inco 718, and I believe the bolts are Inco 718 or A286 (lab analysis pending).
My question is:
Are there separate specs...
Does anyone know if there is a way to put some descriptive text in a sketch for Reference Only? Sometimes it would be helpful to have a brief explanation of what's going on in the sketch.
When I make operation sheets to machine a component, I might say "Op 50, N/C lathe, .03 stk on -A-...
Hi all,
I was wondering if anyone had a solution or workaround for the following:
I have a Extrude-Cut Feature that has one dimension that is different for two configurations. My question is: can the tolerance be different for the two configurations? Is there any other work-around for this?
I...
The problem I'm about to describe sounds like it should be easy to resolve, but has me dumbfounded.
I have a rectangular hole in a plate with a radius (not full) forming one side of the rectangular hole. There is a .025 chamfer on three edges of the hole. The intersecting chamfers have a .040...

While we all love the automatic insertion of dimensions from the model into the drawing, has anyone found an automatic way to attach the end of the dimension line to the end a hole's centerline? SW does not seem to do this unless you make a new dimension and select the hole's centerline. I find...
