With the Whelan unit, no flasher or external power supply (or circuitry) is required. By screen, I assume you mean shielding in the cable. Shielded cable is not required with the Whelan LED strobe. I believe you can ground to the air frame, though it may be better practice to run a ground line back to a common ground point. As was mentioned above, contacting the manufacturers will provide more (and better) info.
Good luck,
