Misfueling Detection with Two Offseted Capacitive Fuel Senders
ثبت نشده
چکیده
Misfueling of a general aviation aircraft with a Jet Fuel instead of an Avgas can have dire consequences. In this paper simple non-destructive testing method is proposed using two capacitive fuel senders that are vertically displaced in a fuel tank by a small distance to detect such situation. Method is based on different readings for the same fuel level in a tank (as fuel senders are displaced). Each fuel has different dielectric constant. In case of correct fuelling difference between these readings will always fall within narrow fixed interval.

Design and simulation of a RF MEMS shunt capacitive switch with low actuation voltage, low loss and high isolation
According to contact type, RF MEMS switches are generally classified into two categories: Capacitive switches and Metal-to-Metal ones. The capacitive switches are capable to tolerate a higher frequency range and more power than M-to-M switches. This paper presents a cantilever shunt capacitive RF MEMS switch with characteristics such as low trigger voltage, high capacitive ratio, short switchin...
