    摘要： The invention relates to an optical system for the detection of a flying or moving object approaching a target, which compriseŝ (a) one or more transmitter-receiver sets positioned at an external surface of a wall of said target, each of said transmitter-receiver sets comprising: (a.1) a light transmitter for creating a fan-like planar or curved optical curtain in front of said wall of the target; (a.2) a receiver which comprises a two-dimensional focal plane array, said focal plane array being spaced apart from said transmitter and being positioned at a plane not parallel to said optical curtain such that a field of view of said focal plane array covers at least a portion of the entire area of said optical curtain; and (b) one or more processing units for determining at least a location of intrusion of said flying object to within said optical curtain by means of determining pixels within said focal plane array that are affected by reflections or scatter due to said intrusion of said flying object.

    摘要： A combined fan-compressor impeller comprises a single hub and a plurality of spaced main blades extending outwardly from the hub such that an air passage channel is defined between two of the main blades. Each of the main blades is a mixed flow blade which continuously extends from a fan section at an inlet end of a channel to a compressor section at an outlet end of the channel without any axial clearance between the fan section and the compressor section, providing aerodynamic matching of pressurized air flowing through the channel from the fan section to the compressor section.
