In this particular instance, the detailed free shape needs to be accurately modeled, as there are potential interference points along the hose routing that must be avoided.
The true free shape (absent gravity and hydraulic loads) should be a path that meets the boundary conditions (position...
Any tips on how to do the following?
Given: Hose endpoints X,Y,Z coordinates, endpoint tangent vectors, and hose length.
How to construct spline that has minimum strain energy for the constraints given above.
I recently changed jobs from being a design engineer in a floundering mom-&-pop chemical manufacturing firm to a design engineer in a major civil/military aerospace firm. I had extensive 2D/3D Autocad experience, some experience in solid modeling with SW, and had also "played" with...
By the way, I forgot to mention earlier...the picture in the link above shows that the wings have a definite anhedral. I'm no aerodynamicist, but I would surmise that the anhedral allows WIG at a lower altitude by minimizing wingtip vortices.
I believe you may be referring to the Boeing Pelican, which if built, will be the largest aircraft (WIG or not) in the world. You can find out more about it at: http://www.boeing.com/news/frontiers/archive/2002/september/i_pw.html.
If your needs are legitimate, the Solidworks Corporation or your local VAR will gladly supply the code. However, since you are trying to run an evaluation on an out of date (by 2 revisions) copy, it seems that you may be trying to get something for nothing. If that is the case, then your on...
Many times the pipe shoe will be "scalloped" where it contacts the pipe to reduce heat transfer. Semicircular cuts are made in the plate so that only 1/4 to 1/3 of the plate actually contacts the pipe.
Could one of the advantages (aside from manufacturing flexibility and cost) of the plastic intake manifolds that are so common now be reduced heat transfer to the intake charge?
Here's a shot in the dark. Poor surface finish could be an indication of heavy finish cuts used when the part was milled. This could have higher residual stresses that would have a negative impact on the part's fatigue properties as well as dimensional stability.
Does anyone know of a good reference which gives the history behind aircraft standardizing on 400 Hz AC? I've heard of many of the advantages related to weight savings, etc., but not the origin of the decision. Why not 200 or 500 Hz?
Tankman650,
Thanks for the advice. This particular tank is relatively small (23 ft diameter) and sits on a concrete foundation, to I don't think punching loads are an issue. Also, the original bottom corroded and was replaced with 1/2" bottom plate. I think I'll still use repads to...
I am looking for suggestions on good reference books that cover hydraulic, pnematic, fuel, and secondary power systems design. Specifically as it relates to tactical fighter jet aircraft. Any suggestions? Thanks.

I am designing internal supports for a large bayonet heater that will be installed in an API 650 oil storage tank. Due to thermal expansion, the heater will have to slide over the supports. It is desired to NOT have cross bracing between the internal supports to resist the lateral loading...
On radiusing the external corners, Asanga brings up good points, as does Corypad. I would add that if the part is to be heat treated, leaving ANY sharp external corners can lead to quench cracking because of the much greater local cooling rate.
