I didn't look at the proE file but the drw looks complicated. I would probably consider using several features to achieve the final result, rather than one or two highly complex features. This method might or might not mimic the manufacturing process; but it might be a quicker way to get a good...
I'm looking for literature to help educate myself on the engineering of magnetohydrodynamic systems. I am interested in MHD pumps using liquid metals and/or ionic liquids. Ideally, a reference would give a first cut at the theory, with a strong focus on practical applications such as the above...
Thanks for the responses. The mystery component in each unit on the 'chain' is a thermo-electric device with internal resistance that results in the above specs.
I have seen reference to much smaller 'numerical relays' used on microprocessors. I am guessing that is a digital technique and is...
I am a mechanical engineer, designing a small aerospace device with a simple electronic circuit. I was working with an EE but he left with work uncomplete, and now I have to finish in a hurry. The device is meant to function in a chain: think of christmas tree lights. I need to select a...
Does anyone know where to find an outgassing specification for the US Air Force? For example, I have this for NASA:
NASA SRP-0022A
Total Mass Loss (TML) 1%
Collected Volatile Condensable Material (CVCM) 0.1%
Values are "not to exceed"
I am looking for something like that for Air Force...
Blimey,
Will you elaborate on this:
<i>If the current system is any of the mainstream mid-range systems (SolidEdge, Inventor, Pro/E (Wildfire), One Space, etc) then the answer is "probably not". </i>
I am using Pro/E Wildfire 3.0. For comparison, I have been on the phone with tech support on...
I am making my first drawing on a new platform (HP nw8440 laptop I believe) and am having issues with display of dimension digits after the decimal: they show up with the minimum number of digits entered (apparently), and do not correspond to the number in the dimension --> properties --> number...
I am a CAD user who is also responsible for administering the system at my company. I am trying to evaluate whether it is worthwhile to switch CAD packages. I would like to know how much time Solidworks users spend with technical support. I am interested in questions like these:
Are you a...
Hi,
Bit of a vague question, I appreciate any help - my company is writing a proposal on a method of embedding an electrical wiring system within a structural element, for aerospace applications. I am writing the part of the work plan describing how we will characterize the requirements on the...
True - hiring the right people is the key and should probably be pursued. Not sure how quickly that will happen, though, since the need is somewhat irregular. Thanks for the input.
Hi - my company is a new, small R&D contractor, primarily for gov (DOD, NIH, etc). We have had about a year of doing one-off prototypes, now we need to start doing real version control and design reviews. The problem - we don't have a lot of experience in what a design review should be! Who...
Hi, I am on the hook for some work for the Air Force and would like to educate myself on small satellite design, especially thermal design/management: payloads that create thermal challenges, thermal management techniques employed (heat pipes, conduction, efficient space radiation) etc. Looking...
I am just getting into creating assembly drawings and BOM's in ProE (Wildfire 2.0), it has been slow going. Trying to figure out how to display the material name for each part in my repeat box. I am storing material name in a user-defined param "MATL", which is loaded from the assigned material...
Hi, I have a question for CAD users - I use ProE daily and am frustrated by its tendency to crash in the middle of a session. This is a hassle because of the time it takes to load the software again, and even more importantly, losing unsaved work. I'm like to know if Solidworks has this tendency...
