Capacitors for Aircraft High Power.
Abstract
Extensive life tests of several dielectric systems have shown that those best suited for pulse discharge energy storage capacitors requiring high energy storage density are paper/K-Film with castor oil (218 joules/pound of active storage volume at 100,000 shots life), paper/Kapton with MCS 1489 oil (120 joules/pound 100,000 shots), paper/polysulfone with silicon oil (94 joules/pound at 100,000 shots) and paper/polypropylene with MCS oil (97 joules/pound at 100,000 shots). All paper capacitors are promising but require further testing and an improved screening procedure to ensure reliability. K-Film is suitable for low pulse rates (a few shots per second) only while polypropylene is best suited for high pulse rates. For moderate pulse rates of a few hundred shots per second, and high temperature operation, both Kapton and polysulfone are attractive. Kapton has the higher energy storage density but polysulfone is considerably cheaper.
