Abstract : Progress is reported on rapid methods for gelling aircraft fuels. The most promising systems consists of amines and diisocyanates. The properties of the gel are influenced by the structure of the amine and isocyanate. Various types of gels can be produced. These include particulate, viscoelastic, and dilatant gels. Gelation rates as fast as 0.04 second were obtained. In addition, several systems will rapidly gel fuel from -55C to 60C. The results show that the various gels will retard the burning rate of the fuels and will contain the fuel while burning. The viscoelastic and dilatant gels have excellent impact properties. The gelation of aircraft fuel will significantly decrease the fuel vaporization rate. A comparison was made of the various gels prepared. Some of the gels are almost as effective at 2.5 weight percent concentration as at a concentration of 4.0 weight percent. (Author)
