I am using my company design manuals at the moment. I do have some references at home which I can check although I think they will be for signal shielding.
You can bond directly to a panel using a bolt, nut, washer, and terminal combination. If this is for current return purposes a #10-32 can handle 35 AMPs Max, 1/4-28 100A, 5/16-28 200A and 3/8-24 245A. The surface under the contact area must be cleaned to bare metal. The...
A typical requirement would be .0005 Ohm per interface. To achieve this a clean smooth contact patch is required or a series of close tolerance fasteners or rivets. What is the application and on what type of structure?
Try the homebuilt aircraft forums. Many homebuilders have had to design their own Prop Reduction Units, PRU's, enabling them to adapt automotive engines. There are several books out on PRU's, they don't go into too much technical detail but they do provide leads to suppliers.
For wire breaks on airplanes in production we use a Time Domain Reflectometer (TDR) made by HP. With the right equipment it will only take minutes to determine the distance from the wire end to the break. But we know where the wire routes and its total length. Finding a cable underground will be...
I reciently had to open up a MOPAR 727 to replace the reverse band which had been damaged while backing a horse trailer up an incline with low fluid, (my wife did it but it was my fault). Upon removing the valve body I found the accumulator spring missing. Now at first I thought that it might...
I have always wondered why small induction motors have ratings up to 6/7 HP yet are still the same size as 2/3 HP motors except having an extra start capacitor(commonly seen on compressors). Industrial motors are twice as big for the same HP. Do they use the same rating system? Is torque a...
Good question. When I was young there were trolley buses that served our neighbor hood as well as electric street cars. My guess is that two major factors were involved; route flexibility and maintenance costs for the power grid. No wait a third factor, which would be cheap fuel. At the time...
We use "Electrolytic (nonsolid electrolyte) Tanatalum, (nonpolarized, etched foil), 85deg C (voltage derated to 125deg C) per Mil-C-39006/2. I have ordered our capacitor/vendor document and will post vendors when it arrives.
