I was laid of at the beginning of the year and have just turned 64. As much as I would like to work another 4-5 years, I don't see much hope in finding a job at this age. Judging from the adds on monster, if you don't match every one of the requirements they don't even want you to apply.
As...
You couldn't possibly mean something like Gordon Blair's book on 4-stroke engine simulation? Although from what little I know about engines most flow is treated as incompressible, with Mach numbers of .6 or less in the intake.
An application that I know of uses a three way catalyst and is probably running stoichiometric. It uses an electronic throttle body with an electronically controlled pressure regulator. The system is made by Econtrols in San Antonio and is expensive. The reason this system was used is that CFR...
There is the large book by Gordon Blair. To me, it is much too oriented toward "buy my program" than presenting good technical writing. I also have a copy of Two Stroke Tuners Handbook by Gordon Jennings, from HP Books. I read it years ago and my recollection is that it is more down to earth.
The v is just a number that you increment, say, from 30 degrees to 90 degrees (which is pi/6 to 3pi/6). Calculate X and Y for each value of v and you will get half of a flank. You can plot X and Y then mirror image it and rotate it 3 times, depending on what cad program you might have, and you...
The Yamamoto equations for the rotor flank are indeed complex and are poorly explained. Both Yamamoto and Ansdale appear to have taken them from a German book that probably can't be found anywhere. The equations do work if you program them into an excel spreadsheet. You have to use either all...
In my home town the local library has a copy of the SAE handbook (which is 4 volumes). Universities with an engineering program should have them as well. Otherwise you need deep pockets to get anything from SAE, even if you are a member for $75 a year dues.
Try to find the book by Yamamoto, it has all the equations. It might be out of print but I have seen a pdf of it somewhere on the internet. Unfortunately, I don't remember where.
There are lots of SAE papers from the Curtiss Wright days. Your research won't be complete without them.
Calculations may not do much good since they are based on assumptions about how smooth the engine should run (I don't remember the name of the fudge factor). Find the polar moment of inertia of your current one, then design one say 10% or 20% greater and see if it makes a difference. You just...
Hello,
I need advice from people who do contract work. I'm approaching 64 and just lost my job (engineering). I am thinking about laying low for a few months to see if the economy starts to improve, and then finish my career by doing contract work. I see that Aerotek is encouraging older people...
I searched one time and found nothing. I needed to design a throttle body and had a drawing of a Zenith carburetor to compare it to. The weird thing about it was the shaft for the throttle was located .030" below the axis of the bore. No one I talked to could explain why. I would have just put...
SAE published or sold a book on gearbox design a few years ago. I'm out of town so I can't get the name, and don't know if it is still in print. It was not a very good book, but better than nothing. (actually it might be by the same Stokes mentioned above, but different title)
Don't try for any more accuracy than you need. In this type of work you can often get by with a simplified model, and Solidworks might force you to do that anyway. You may not need every curve, component, or fastener if you just need to check for clearances or find places to mount things.
I...
I have several equations and all I want to do is enter some data, run the calculations, increment the input, and list the result. Plotting the result would be nice but I suppose I could just copy it into excel.
A previous thread mentioned Mathcad, which is priced out of my reach, and Python...
There are numerous industrial engine distributors in the US. North Coast Ford in Ohio is one of them. Whoever you contact will probably refer you to a local dealer.
What? You are a pay grade higher than what the desired job pays, and you think the company will pay you more than you get now to transfer to a job where you should be getting less than what you currently make???? Or am I reading this wrong?
The only thing I can offer from experience is that...
Mr. Tick, I like your poster. We also have a GC here but I always go to the local drum shop, because it is such a pleasure to deal with people who are honest and really know what they are doing.
When I was young and not very smart, I bragged to an older coworker about my raise, not realizing at the time that he got much less probably because he was considered past his prime. Of course, he went in the office and raised hell about it, and I ended up getting an ass-chewing since I...
