HIGH ANGLE OF ATTACK MISSILE AERODYNAMICS WORKSHOP The Munitions Directorate of the Air Force Research Laboratory and the Weapons Division at China Lake Naval Air Warfare Center (NAWC) will jointly sponsor a High Angle-of-Attack Missile Aerodynamics Workshop at the Eglin Conference Center, Eglin AFB FL, on 15-17 October 1997. The workshop will bring together government, industry and academic experts in missile aerodynamics and control to not only discuss, but to plan technology development in four aspects of high angle-of-attack missile flight: external aerodynamics of maneuvering missiles; aerodynamics and autopilot integration; innovative flow sensing and control; reaction jet interactions. The workshop will develop a road map of the steps required to research, evaluate, and develop the technologies to overcome significant aerodynamic challenges of next-generation agile weapon system concepts such as the Dual Range Missile (DRM). The DRM concept is jointly endorsed by the USAF and USN through Joint Tactical Air-to-Air Missile Office (JTAAMO) coordination efforts and incorporates several laboratory advanced development programs. The workshop will generally be unclassified, but may have classified sessions if required. No foreign nationals will be authorized to attend. Workshop Format: The workshop will begin with an overview to set the stage for the meetings, present basic research areas to be addressed, identify the short-term and mid-term needs of the DRM concept and focus attention on what is desired to support agile missile flight demonstrations planned in 2001-2006. Following the overview, attendees will break up into four subgroups as follows: External Aerodynamics of Maneuvering Missiles. A more in-depth understanding of the flow physics associated with missiles undergoing high pitch rates, up to 90 degrees AoA, in the subsonic and transonic speed regimes is sought using analytical, experimental and numerical techniques. Aerodynamics and Autopilot Integration. Performance enhancements of missiles at high AoA will be explored by integrating real-time flow field sensing and control with innovative control schemes, including adaptive controls technology. Emphasis will be on developing robust control algorithms incorporating real-time state information, as well as a hybrid of innovative aerodynamic and reaction jet control techniques. Innovative Flow Sensing and Control. Non-obtrusive techniques to sense and actively control the flow field of a missile at high AoA are sought. These techniques include, but are not limited to, the application of Micro-Electronic Mechanical Systems (MEMS). Reaction Jet Interactions. A more detailed understanding of the interactions of a reaction jet, in close proximity to fin control surfaces, with the external flow field of a missile at high AoA is sought using analytical, experimental and numerical techniques. Subgroup formats will allow for short, concise and informal presentations of on-going work that is pertinent to the specific subgroup subject matter. Following the presentations, technical discussions will ensue to identify and document the research necessary to support specific missile technologies, proposed time frames and level of effort for accomplishing the research, and how the research benefits planned agile missile flight demonstrations. For the final half day, the subgroups will present their results and recommendations to a general session of all the attendees. The subgroup reports will be collected and bound into a report of the proceedings of the workshop. Recommendations resulting from the panel reports will be forwarded to the appropriate USAF and USN technology managers for funding consideration. Workshop Objectives: Review pertinent past and on-going research efforts, Identify the right technology to be developed to meet 5 year and 10 year Dual Range Missile (DRM) IPT Objectives, Identify technology development issues and payoffs, Coordinate planned research efforts in government, industry and academia to leverage available funding and minimize duplication, and Layout a technology development roadmap, identifying needed programs and providing rationale for funding.
