NASA Dryden, together with Lhc US. Air Force, McDonnell Douglas Aerospace, and Pratt & Whitney, arc developing a test aircraft capable of flight demonstrating a wide spectrum of aerodyriamic and propulsion Integration technologies for future commercial aud military aircrralt. The features of this testbed, the F-15 hdvnticcd Control Technology for IntegratedVchiclcs, or ACTIVE, are described, togctfier wih a summary of thc programs planned to be demonstrated.The aircraft is equipped with two axisymmctric pitch ,and yaw thrust vectoring nozzles, a quadruplex digital integmtcd flight propulsion control system, a high throughput/ high memory Vehicle Management System Computer, two Electronic Air Inlet Controllers, and two Improvcd Digital Electronic Engine Controls. 'These electronic controls arc fully integrated via five 1553 Multiplex busscs. Ilhc ACTIVE testbed will initinliy be used to demonstrate performance improvemcnts from thrust vectoring and For quantifying the jet intcrnction cffects generated by thrust vectoring. In futurc programs, tliis state-of-the-art testbed will demonstratc ;i sdf-repairing neural network flight control, ttie ability of vectoring nozzles to eliminate vertical tails, anti it multi-variable fully intcgratcd aerodyrianiic and cnginc control. Tlie fully integrated flight, propulsion, and vehicle management computers make this aircraft a unique resource for future integration testing. -1 ACTIVE AdAPT A8 A9 BRN RC cc EAIC FC 1;7..,IR g J Nomenclature -Advanced Control Technology for htcgrated Veh ides
Many of the next generation fighter engines are being developed with advanced multi-function exhaust nozzles. The nozzles with new thrust vectoring and reversing capabilities will be used lo augment normal aerodynamic flight control effectors and to enhance rapid thrust response for flight maneuverability and short takeoff and landings. A significant evolution of nozzles will emerge from current practice and control system technology will evolve. to provide optimal management 1 Copyrighl 0 1990 American I n~l i l~t e of Aeronautics and Aslmnmlics.
