Public award description
THE SUBSONIC FIXED WING PROJECT OF THE FUNDAMENTAL AERONAUTICS RESEARCH PROGRAM IS SUPPORTING RESEARCH AIMED AT INCREASING THE EFFICIENCY OF SUBSONIC FIXED-WING AIRCRAFT. FOR LOW SUBSONIC SPEEDS, AN UN-SWEPT FLYING WING CONFIGURATION RESULTS IN SUBSTANTIALLY LOWER DRAG AND STRUCTURAL WEIGHT, WHEN COMPARED TO A CONVENTIONAL CONFIGURATION WITH FUSELAGE AND EMPENNAGE. THE NEAR ABSENCE OF ROTATIONAL INERTIA AND CONTROL MOMENT ARM ABOUT THE PITCH AXIS, HOWEVER, RENDERS SUCH A CONFIGURATION PROBLEMATIC FROM A STABILITY AND CONTROL STANDPOINT. THIS ISSUE CAN BE RESOLVED BY INTRODUCING A SUFFICIENTLY LARGE ANGULAR MOMENTUM BIAS INTO THE VEHICLE BY INSTALLING A CONSTANT-SPEED FLYWHEEL IN THE AIRFRAME.
