电磁场与电磁波 第6章平面电磁波 合KK Have Blue HB 1001 Pole gesting This three-view depicts the first of the two Have Blue The Hying af the HiB 1002 experimental aircraft.which paved the way for the design of the against real rodars in an full-seale'Stealth Fighter.It wore this strange scheme to hide operational environment was its unique faceted surface,although the second Have Blue was the culmination of a long RCS finished in an all-over grey.HB 1001 also differed by having a triais programme,which began large instrumentation boom attached to its nose. with the testing of small,third scate and fullscale modols on poles.These tests showed the tadar 'flare-spots'-areas of too much radar rellectivity Systems Have Blue utilised many off-the shelf systems from other aircraft. including the lly-by wire system from the F-16.The aircraft also had the F-16's sidestick controller,while the undercarrage came ftom the Northrop F-5.The two engines came from a Rockwell T-28 Buckeye. Flight control systems Flight control systems were served by three static pressure sensors on the forward fuselage,and three total Configuration prossure probes,one on the nose and two on the cockpit windscreen post. Have Blue validated the faceting concept. HB 1001 also had the instrumentation and the basic aircralt shape.Key boom which correlated data from the differences were the inward-canting of primary systems. the fins.which were mounted on the outside of the main fuselage body and much further forward than on the production aircraft.The leading edge was 50 t at a very sharp72.5° Stealthy exhaust The exhaust slot for the Have Blue had p greater extension on its lower hp than was featured on the F-117,with its two exhaust siots meeting at a common point on the centreline.The lower portion of the nozzle formed a two-position plate which automatically
