IGF::OT::IGF THE HIGH SPEED PROJECT IS A NASA ARMD FUNDAMENTAL RESEARCH PROJECT ALIGNED WITH THE STRATEGIC GOALS AND OBJECTIVES DESCRIBED IN THE NATIONAL AERONAUTICS RESEARCH AND DEVELOPMENT PLAN AND THE 2014 NASA AERONAUTICS STRATEGIC PLAN. THE HIGH SPEED PROJECT IS AIMED AT PROVIDING THE RESEARCH AND LEADERSHIP TO ENABLE THE DEVELOPMENT OF A NEW GENERATION OF SUPERSONIC CIVIL TRANSPORT AIRCRAFT. THE PROJECT S NEAR TERM OBJECTIVE IS TO DEVELOP THE TOOLS AND INTEGRATED CONCEPTS THAT WILL ENABLE DEMONSTRATION OF OVERLAND SUPERSONIC FLIGHT WITH ACCEPTABLE SONIC BOOM. THE CURRENT REGULATORY PROHIBITION OF FLIGHT THAT PRODUCES A SONIC BOOM OVER POPULATIONS IS VIEWED AS THE PRINCIPAL BARRIER TO FUTURE SUPERSONIC CIVIL AVIATION. A KEY ELEMENT OF THE HIGH SPEED PROJECT IS EXPERIMENTAL FLIGHT VALIDATION OF PREDICTIVE METHODS, CONCEPTS, AND TECHNIQUES. INCREASED EFFECTIVENESS OF CURRENT SYSTEMS OR BETTER TECHNIQUES AND METHODS ARE NEEDED TO INCREASE PRODUCTIVITY OF VALIDATION OPPORTUNITIES. AIRCRAFT MANUFACTURERS HAVE DECLARED THAT A COCKPIT DISPLAY SHOWING SONIC BOOMS WILL BE ESSENTIAL FOR ANY FUTURE CIVILIAN SUPERSONIC AIRCRAFT, AND ITS USE IS ENVISIONED TO BE AN IMPORTANT ELEMENT OF A NEW CERTIFICATION STANDARD FOR LOW-BOOM OVERLAND FLIGHT. A NUMERIC MODEL WILL BE DEVELOPED, REFINED AND EXERCISED OVER THE THREE YEARS. FLIGHT TESTS WILL BE CONDUCTED AT SEVERAL LOCATIONS. THE FIRST TEST WILL BE CONDUCTED AT ARMSTRONG FLIGHT RESEARCH CENTER, FOR CONTINUITY WITH THE BULK OF PRIOR FLIGHT TESTS. THE REMAINING TESTS WILL BE CONDUCTED AT DIVERSE LOCATIONS IN THE UNITED STATES. LOCATIONS WILL BE IN EXISTING SUPERSONIC AIRSPACES USED BY THE MILITARY. VARIETY AT EACH LOCATION WILL BE OBTAINED BY FLYING AT DIFFERENT TIMES OF DAY. ATMOSPHERIC CONDITIONS WILL BE DOCUMENTED, SO THAT FLIGHT TEST CONDITIONS CAN BE USED AS INPUT TO THE NUMERIC MODEL. THE RESULTS OF EXERCISING THE NUMERIC MODEL WILL THEN BE USED TO DEVELOP PRACTICAL ALGORITHMS FOR SIGNATURES AND LOUDNESS THAT WILL BE INCORPORATED INTO PCBOOM, NASA S GENERAL PURPOSE SONIC BOOM PROPAGATION SOFTWARE.
