The proliferation of antenna systems of state-of-the-art military aircraft has challenged major airframe manufacturers to provide additional outer surface platform space for antenna placement while still maintaining a flightworthy structure. The solution is to design antennas that can sustain severe structural load. The recently completed 'RF Multifunction Structural Aperture (MUSTRAP),' contract number F33615-97-2- 3807 performed by Northrop Grumman Corporation (NGC), El Segundo, California and TRW/ASD, Rancho Bernardo, San Diego, California, together with their DoD customer have met this challenge by conceiving the novel technology of Conformal Load-bearing Antenna Structures (CLAS). Under the Air Force Research Laboratory, Air Vehicles Directorate, Structures Division's leadership and direction, the MUSTRAP team have developed multifunction, broadband, structurally integrated, low cost antennas for communications, navigation, identification (CNI) and electronic warfare (EW) applications in the 0.03 to 2.0 GHz range. Two concepts, a fuselage and a vertical tail installation, were designed, analyzed, fabricated, and tested. The fuselage demonstration article was a load bearing multifunction (UHF/SATCOM) antenna 35 by 37 inch panel subjected to combined axial and shear loading, which replicated realistic flight conditions. Ultimate failure loads imposed on the panel were 1,800 pounds per inch axial loading and 600 pounds per inch shearing loading, after successfully withstanding a single lifetime (6,000 hours) of fatigue. Electrical performance was validated using anechoic chamber measurements. The vertical tail concept was a structural excitation multifunction (VHF/UHF) antenna element that can be tailored to fit in virtually any end cap vertical tail configuration. Designed to endure the severe acoustic environment associated with empennage noise sources, the end cap was successfully flight tested on NASA/Dryden's Systems Research Aircraft (SRA) to validate the structural and electrical performance. Highlights of the program are presented in the text.

The DARPA/AFRL/NASA Smart Wing program, conducted by a team led by Northrop Grumman Corporation (NGC) under the DARPA Smart Materials and Structures initiative, addresses the development of smart technologies and demonstration of relevant concepts to improve the aerodynamic performance of military aircraft. This paper presents an overview of the smart wing program. The program is divided into two phases. Under Phase 1, (1995 - 1999) the NGC team developed adaptive wing structures with integrated actuation mechanisms to replace standard hinged control surfaces and provide variable, optimal aerodynamic shapes for a variety of flight regimes. Two half-span 16% scale wind tunnel models, representative of an advanced military aircraft wing, one with conventional control surfaces and the other with shape memory alloy (SMA) actuated smart control surfaces, were fabricated and tested in the NASA Langley Research Center (LaRC) Transonic Dynamics Tunnel (TDT) wind tunnel during two series of tests, conducted in May 1996 and June 1998, respectively. Details of the Phase 1 effort are documented in several papers. The on-going Phase 2 effort discussed here was started in January 1997 and includes several significant improvements over Phase 1: 1) a much larger, full-span model; 2) both leading edge (LE) and trailing edge (TE) smart control surfaces; 3) high-band width actuation systems; and 4) wind tunnel tests at transonic Mach numbers and high dynamic pressures (up to 300 psf.) representative of operational flight regimes. Phase 2 includes two wind tunnel tests, both at the NASA LaRC TDT - the first one was completed in March 2000 and the second (and final) test is scheduled for April 2001. The first test-demonstrated roll-effectiveness over a wide range of Mach numbers achieved using a combination of hingeless, smoothly contoured, SMA actuated, LE and TE control surfaces. The second test addresses the development and demonstration of high bandwidth actuation. An overview of the Phase 2 effort is presented here; detailed discussions of the wind tunnel testing, model design and fabrication, and actuation system development are given in companion papers.
