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电磁场与电磁波 第6章 平面电磁波
