The shuttle's forward reaction control system, or RCS, includes 14 primary engines and two vernier jets. Two aft RCS pods feature 12 primary thrusters and two verniers each. The primary engines generate 870 pounds of thrust while the verniers produce just 24 pounds of push.The software we were analyzing was the DAP jet-select and deadbanding (more than you ever wanted to know here). We spent a lot of time with this "Phase-plane" diagram.
Changing subjects, a Wyland painting was stolen from a Waikiki store on Lewers Street. Which is more surprising: that it was snatched from a gallery during business hours, or that there's a Wyland painting worth $700k? :) Anyway, support your local tiki.
