Hybrid Meeting Minutes 10/05/03


In attendance: Eric Hettinger, Brian O’Neel

Topics Discussed:

The layout of the gaseous plumbing system was discussed more in detail. It was decided to hard mount all of the solenoids and the metering orifice into one location approximately 3 feet from the combustion chamber and behind a protective barrier. This established the required feed hose lengths to:

(1) 3ft x 3/8" I.D. (1500 psi) braided stainless steel oxygen line
(1) 18 ft x 3/8" I.D. (1500 psi) braided stainless steel oxygen line
(1) 18 ft x 1/4" I.D. (300 psi) nitrogen purge line

This will allow for us to fit the entire motor test facility onto the mobile trailer.

Also today Eric brought over the Viton o-rings and we got the grooves cut on the nozzle and inject plate to accommodate them. The fits seem to be good.

Jim W. is working up the data acquisition system and we are still keeping our eyes open for the correct pressure and load cells.

We are currently a little behind schedule due to the recent LV2 launch but now that that is over we hope to get back on track with the hybrid development and possibly be ready to do the static test fire in 2 months.

The next hybrid meeting will be in 2 weeks.
