FUNCTIONALLY TAILORED MULTI COMPONENT COMPOSITE STRUCTURES VIA ADDITIVE MANUFACTORING. THE OBJECTIVE OF THIS PROJECT IS TO EXPLORE THE POTENTIAL FOR CREATING A FULLY DENSE MULTI-ALLOY COMPOSITE STRUCTURE WITH A CONTROLLED INTERNAL RESIDUAL STRESS FIELD. THIS WILL BE ACCOMPLISHED THROUGH THE USE OF A ONE-WAY SHAPE MEMORY ALLOY MATERIAL INCORPORATED INTO A STRUCTURAL ALLOY MATERIAL IN A CAREFULLY DESIGNED CO-CONTINUOUS RETICULATED ARRANGEMENT. ADDITIVE MANUFACTURING TECHNIQUES WILL BE USED TO CREATE THE MATRIX COMPONENT (FIGURE 1) USING A STANDARD ENGINEERINGALLOY TI-6AL-4V. THE VOIDS IN THE MATRIX WILL BE FILLED WITH NITINOL SMA POWDER HOT CONSOLIDATED AND SHAPE-SET INTO A FULLY DENSE ARRANGEMENT. THIS COMPOSITE STRUCTURE WILL THEN BE MECHANICALLY WORKED IN ORDER TO INTRODUCE RECOVERABLE PLASTIC STRAIN INTO BOTH THE MATRIX AND THESMA. UPON MEMORY ACTIVATION HEAT TREATMENT THE SMA WILL ATTEMPT TO REVERT TO ITS ORIGINAL SHAPE-SET DIMENSIONS (I.E. CONTRACT) BUT WILL BE CONSTRAINED BY THE TITANIUM ALLOY MATRIX. THE RESULT WILL BE A STRESS STATE SHOWN CONCEPTUALLY IN FIGURE 2. AS CRACKS GENERALLY NUCLEATE AT AFREE SURFACE THE COMPRESSIVE FIELD IN FRONT OF THE CRACK TIP WILL INHIBIT THEIR PROPAGATION. THE STRESS INTENSITY FACTOR (K) IS RELATED TO THE LOCAL STRESS FIELD ( ) BY ! = ! !". CAREFUL DESIGN OF THE STRUCTURE AND THE RESULTANT INTERNAL STRESS FIELD SHOULD ALLOW THE STRESS INTENSITY FACTOR TO REMAIN BELOW THE THRESHOLD VALUE THUS INHIBITING ANY CRACKS FROM GROWING. AND BY THE NATURE OF THE INTERLOCKING ARRANGEMENT OF THE SMA/ALLOY COMPOSITE CORE ANY CRACKS INITIATING IN THIS AREA WILL BE CONTAINED AND ISOLATED FROM THE LOAD BEARING STRUCTURAL LAYERS. FOR THIS INITIAL STUDY DETAILED CHARACTERIZATION OF THE MATERIAL WILL BE CONDUCTED UTILIZING MECHANICAL TESTING ELECTRON MICROSCOPY AND NEUTRON DIFFRACTION. ADDITIONALLY THE APPLICABILITY OF THIS METHOD FOR PRODUCING HIGH STRENGTH HIGH TOUGHNESS AEROSPACE STRUCTURAL COMPONENTS WILL BE EVALUATED ALONG WITH POTENTIAL DUAL USE APPLICATIONS OUTSIDE THE AEROSPACE MARKET.

THE OVERALL GOAL OF THIS PROPOSED PROJECT IS TO SUPPORT SAFE OPERATIONS OF UNMANNED AERIAL VEHICLES (UAVS) FOR URBAN MOBILITY. THE INITIAL FOCUS WILL BE ON SMALL OCTOCOPTER UAVS PRIMARILY EMPLOYED FOR PACKAGE DELIVERY IN URBAN SETTINGS BUT LATER WE WILL EXTEND THE WORK TO APPLY TO LARGER UAVS SUCH AS AIR TAXIS THAT MAY BE USED FOR URBAN TRANSPORTATION BY HUMANS. WE WILL DEVELOP A FRAMEWORK AND COMPUTATIONAL ARCHITECTURE THAT IS GENERAL AND SCALABLE. SOME THE KEY CONSIDERATIONS AND HIGHLIGHTS OF OUR OVERALL APPROACH ARE: (1) INTEGRATED ON BOARD AND OFF BOARD SCHEMES FOR MONITORING UAV FLIGHTS FOR INDIVIDUAL VEHICLES AND THE FLEET OF VEHICLES TO MANAGE FLIGHT OPERATIONS REDUCE FLIGHT RISKS AND MAINTAIN FLIGHT SAFETY; (2) SHORT-TERM AND LONG-TERM DECISION MAKING SCHEMES THAT WILL INCLUDE ANALYZING RISK ASSOCIATED WITH THE CURRENT TRAJECTORY GIVEN THE EXISTING ENVIRONMENTAL CONDITIONS CONTINGENCY MANAGEMENT AND FAULT-ADAPTIVE CONTROL TO MAINTAIN SYSTEM TRAJECTORY AND OPERATIONS; AND (3) STUDYING THE EFFECTS OF MULTIPLE INTERACTING SUBSYSTEMS OF THE UAV ON SYSTEM PERFORMANCE ESPECIALLY UNDER DEGRADED AND FAULTY CONDITIONS. WE WILL WORK CLOSELY WITH RESEARCHERS AT NASA AMES TO DEVELOP THE EXISTING HARDWARE-IN-THE-LOOP TESTBED AND RUN EXPERIMENTAL STUDIES ON THIS TESTBED TO DEMONSTRATE THE EFFECTIVENESS OF OUR COMPUTATIONAL ARCHITECTURES AND DECISION-MAKING ALGORITHMS FOR A NUMBER OF RELEVANT SCENARIOS
