Materials Data on KBaP by Materials Project

KBaP is half-Heusler structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. K1+ is bonded in a distorted body-centered cubic geometry to four equivalent Ba2+ and four equivalent P3- atoms. All K–Ba bond lengths are 3.19 Å. All K–P bond lengths are 3.19 Å. Ba2+ is bonded in a distorted q6 geometry to four equivalent K1+ and six equivalent P3- atoms. All Ba–P bond lengths are 3.68 Å. P3- is bonded to four equivalent K1+ and six equivalent Ba2+ atoms to form a mixture of distorted face and corner-sharing PK4Ba6 tetrahedra.

A NASA/RAE cooperation in the development of a real-time knowledge based autopilot

As part of a US/UK cooperative aeronautical research program, a joint activity between NASA-Ames and the Royal Aerospace Establishment on Knowledge Based Systems (KBS) was established. This joint activity is concerned with tools and techniques for the implementation and validation of real-time KBS. The proposed next stage of the research is described, in which some of the problems of implementing and validating a Knowledge Based Autopilot (KBAP) for a generic high performance aircraft will be studied.
