- Description
- Air Force Research Laboratory, Air Vehicles Directorate, Aeronautical Sciences Division (AFRL/VAA) solicits research proposals for Task 2 of the Active Integrated Inlet-Duct-Engine Demonstration (AIIDED) program. The AIIDED program seeks to demonstrate the integration of both the inlet aperture and duct closed-loop flow control systems in a very-compact, highly-offset inlet to maximize propulsive efficiency and robustness to flight condition while minimizing reliability pitfalls such as high-cycle fatigue. Recent developments in closed-loop flow control ? active flow control integrated with sensors through feedback ? demonstrate the performance enhancement potential for aggressive inlet systems. In particular, the Structurally Integrated Compact Inlet Technology (STRICT) program has demonstrated the aerodynamic and structural weight efficiencies to be realized from designing an aircraft inlet system using flow control as an enabling technology. Boundary layer flow control may further aid in the integration of the forebody and inlet by providing a ?virtual? boundary layer diverter, allowing the aerostructural design of inlet aperture de-emphasize flow quality requirements in favor of other geometric and/or weight constraints. Desired characteristics of the integrated configuration are: an advanced, conformal inlet aperture with integrated forebody; duct-diffuser length to diameter ratio (L/D) objective of 2.0, with a threshold L/D of 2.5; compatibility with current low-observable design philosophies and requirements, including 100% line of sight blockage to the engine face at all viewing angles; designed using advanced probabilistic hammershock load methodologies; manufactured using advanced production methodologies; a robust closed-loop flow control system integrated into the inlet aperture, duct and/or diffuser; an advanced turbine engine; configuration applicable to future UAVs such as UCAV and Sensorcraft. The demonstrations should show that this integration has positive or no degrading effect on installed propulsive efficiency and reliability when compared to less aggressive inlets designed to current engineering standards (e.g., F-35 / JSF). Analysis and tests include, at a minimum: integrated closed-loop flow control system demonstrations, including dynamic control; integrated forebody-inlet aero-control demonstration showing system robustness; installed aeropropulsion performance demonstration; structural integrity and producibility of integrated, flight-ready hardware. Additional testing required to bring the Technology Readiness Level of the integrated actively-controlled inlet to a level 6 should be accomplished. Demonstration of integration details including actuator and sensor structural integration, power requirements, control system architecture and integration, structural failure criteria, dynamic distortion prediction methodologies, and inlet/engine interface requirements is important to reduce risk for future programs that will utilize this technology. This design should present net weight and installed performance benefits and minimal additional power and other interface requirements over the current state of the art. The Versatile Affordable Integrated Inlet-Fan for Performance and Reliability (VAIIPR), Task 1 of the AIIDED program, will demonstrate the integrated performance of a flow-control-enabled duct flow path with an advanced fan. Importantly, this demonstration will quantify the benefit inlet flow control will have on the high-cycle fatigue characteristics of highly-loaded fan stages. .
