Orbital Research Inc. - Active Flow Control Statement of Work 2/26/09

1.0 Introduction SAIC is investigating under IR&D the use of active flow control approaches for use on guided projectiles. SAIC believes that the use of active flow control technology can provide low cost, low power, space efficient control effectors that are ideal for the precision control of certain gun and mortar launched guided projectiles.

The objective of this program is to develop an active flow control approach for existing 105mm spin stabilized artillery projectiles. Specifically, the project is intended to develop the following:  An aerodynamic model with active flow control demonstrating the flight control capability and accuracy of the approach  Conceptual design of an active flow control approach for the nose of a 105mm artillery projectile

SAIC believes that the analytical feasibility of active flow control demonstrated in this program may lead to a flight demonstration program.

2.0 SOW Tasks The subcontractor shall follow a disciplined engineering development process that includes systems engineering, design analyses, modeling, simulations, inspections, engineering tests in supporting the development of feasible active flow control approach. The subcontractor shall complete the following tasks.

2.1 Requirement Development The subcontractor shall work closely with SAIC to develop requirement specifications for an active flow control system on the nose of a 105mm artillery projectile. These requirements will include gun launch survival (20,000g setback, 5000g balloting), flight performance while spinning (up to 340 Hz), mechanical and electrical interfaces, and aerodynamic surface and sensor requirements.

2.2 Baseline Active Flow Control Design The subcontractor shall provide several candidate design implementations of active flow control that will be analyzed and traded for system performance. From these the subcontractor shall develop a baseline active flow control design that best meets the derived system specifications. In defining the baseline design, the subcontractor shall perform actuation system trade studies to determine the best Flow Control Actuation System (FCAS) design, including type, size, shape, material, number, placement, and operational characteristics to support the projectile system design. The subcontractor shall work with SAIC in defining the mechanical and electrical interface requirements for this design.

2.3 Baseline System Aerodynamic Model Support The subcontractor shall work with SAIC in the establishment of an aerodynamic model for the baseline active flow control design. SAIC will provide the baseline projectile physical and aerodynamic model. The subcontractor shall provide incremental aerodynamic characteristics to the model for the baseline active flow control design that shall be derived from wind tunnel data, computational fluid dynamics (CFD) analysis, and previous flight test data available to the subcontractor. The subcontractor shall provide recommended active flow control actuation algorithms for the sensors and actuators selected for the system design. The subcontractor shall work with SAIC to select the best system implementation of active flow control.

2.4 Program Communications The subcontractor shall participate in weekly conference calls with SAIC to develop plans, status activities, and define needed information for the execution of the program.

2.5 Final Report The subcontract shall deliver a final report in subcontractor format that provides documentation on the configurations investigated, summary of analyzes performed, and recommendations forward.
