The surfaces I generate were driven by curvature-controlled splines and lofted area-controlled profiles. The surfaces were then analyzed for performance and efficiency with CFD. Wind tunnel testing demonstrated that the outboard inlet achieved an efficiency of __% and there was extremely low variation between CPD predictions and Wind Tunnel Data (as shown in the image below). https://images.squarespace-cdn.com/content/v1/6012c667333305652fe566f8/1614698935430-9G374L15D4PZSLYWQTLZ/ob+inlet+9+wind+tunnel+data.png XB-1 Outboard Inlets https://images.squarespace-cdn.com/content/v1/6012c667333305652fe566f8/1614742409611-FTJMIDYSRGSGDWSWOPRI/ob+inlet+xb1+5x+deformation.gif XB-1 Outboard Inlets The under-wing inlets deflect outboard and upwards on the order of an inch. This deflection led to challenging sliding interfaces between the inlet and the fuselage and between the inlet and the wing. https://images.squarespace-cdn.com/content/v1/6012c667333305652fe566f8/1614699455327-XELWU1ORJ45EYU6BYNK2/OB+inlet+5..PNG XB-1 Outboard Inlets - Initial Structural Layout Once we validated the loft surfaces, we laid out the composite primary structure and mechanism conceptual designs. The layout included frames that gave stiffness to the inlet duct and nacelle components, as well as actuated ramps and doors for optimizing engine efficiency across the flight envelope. The deflections between the inlets and the fuselage were high. As a result, determining constraints of the inlet attachment points was one of the most challenging aspects of the design. https://images.squarespace-cdn.com/content/v1/6012c667333305652fe566f8/1614742663569-1FRJ9U0A741US2WJDFUN/ob+inlet+7.PNG XB-1 Outboard Inlets All components had minimum margins close to zero. This approach ensured that all our components were just stiff enough and just strong enough to withstand predicted flight loads. Most of our structure was sized by abrupt yaw cases and hammershock cases. https://images.squarespace-cdn.com/content/v1/6012c667333305652fe566f8/1614699838654-K24B9X01T9JD3JLK8Q66/fs682+frame.PNG XB-1 Outboard Inlets - Optimized Carbon-Composite Laminates Once we had a conceptual design that closed, we proceeded to optimize all primary structure to reduce weight. Each colored region in the picture to the right indicates a different ply count. By reducing ply counts to only what was necessary for each region, we were able to reduce weight of frames by 22%. https://images.squarespace-cdn.com/content/v1/6012c667333305652fe566f8/1614741586265-JT7VWK9B6MKM7XNF0XGZ/ob%2Binlet%2BCPD%2Bnacelle.jpg XB-1 Outboard Inlets - Carbon-fiber Ply Design I learned CPD from our leading composites expert at Boom. As a result, I was able to achieve within 2% of the predicted FEM stiffness in the as-built composite parts. The stiffness and quality of a composite part relies heavily on how the plies are spliced and darted and what seed points are chosen. Flattened patterns of nacelle plies are shown in the image to the left. https://images.squarespace-cdn.com/content/v1/6012c667333305652fe566f8/1614743491030-49W334US1WOAIAGY9XO3/inlet%252Bduct.jpg XB-1 Outboard Inlets View into the righthand inlet duct as the CFOAM tool is being chiseled away https://images.squarespace-cdn.com/content/v1/6012c667333305652fe566f8/1614741804478-5ZOKTPL5VCXJDCYLCTTT/IMG_3336.jpg XB-1 Outboard Inlets - Assisted Fabrication at the Vendor Due to weight savings optimization, the outboard inlet composite parts increased in complexity. Some composite frames (like the one shown below) had over 200 carbon fiber cut pieces that all needed to be placed with high accuracy. The inlet ducts were also extremely challenging to fabricate because the tool needed to be chiseled out by hand after the parts finished curing in the autoclave. As a result, it was vital to have engineering support on-site. While supporting in an engineering capacity, I also had the opportunity to layup parts I designed with experienced composite technicians. https://images.squarespace-cdn.com/content/v1/6012c667333305652fe566f8/1614742753340-RG8IJJT4VDK4JQWEA0W3/IMG_3342.jpg XB-1 Outboard Inlets View of a tight corner in one of the outboard inlet frames. Tight corners required many darts and patch plies https://images.squarespace-cdn.com/content/v1/6012c667333305652fe566f8/1614743726294-WYM9L8WG5XDCC02ZGUBS/ob+inlet+layup.png XB-1 Outboard Inlets View of core being laid up on the lefthand inlet duct. https://images.squarespace-cdn.com/content/v1/6012c667333305652fe566f8/1614744040623-SYRKNQV8NSO5BLZLRTES/ob+inlet+11.png XB-1 Outboard Inlets - Supported Assembly and Nonconformances The outboard inlets were jigged, bonded, and fastened in five weeks. This accelerated schedule required copious engineering support and diligent planning ahead. On the engineering side, I created work instructions, reviewed bond gaps with metrology, checked bond fillets, and create fastener vector files. However, I also got my hands dirty; I helped glue jigs to aircraft hardware, bond prep carbon fiber components, mix adhesive, fillet critical bonds, and pop a few rivets. This phase of the build has been my favorite aspect of the design cycle! https://images.squarespace-cdn.com/content/v1/6012c667333305652fe566f8/1614806352647-CJBDA453L52X2N99FJKP/IMG_4288.jpg XB-1 Outboard Inlets https://carolinekrawczyk.com/j-85-engine-mice daily 0.75 2021-03-17 https://images.squarespace-cdn.com/content/v1/6012c667333305652fe566f8/1614804025246-XSZ7OV4OPC2NZZLUMMU0/IMG_0428.jpg J-85 Engine Mice - Design Overview Engine mice (shown in silver in the image to the left) attach to the inner nozzle flaps of an adjustable area nozzle. They are test parts that are used to constrict the area at the throat of the engine to get stall data across the engine operating environment.

Specifying grain boundaries can lead to superior shock absorption properties for missile defense and ISS/satellite external structure (Image on right shows samples made for the Army Research Labs. Samples were hypersonic shock tested.) https://images.squarespace-cdn.com/content/v1/6012c667333305652fe566f8/1614867656536-RCKMOS9TBGBKGOS64VCW/grain+boundary+4.PNG Grain Boundary Research - From Theory to Execution The proprietary process was developed by a PhD student, a material science student, and myself. It was the first time the theorized grain boundary control method (shown in the image to the left) had been executed in a lab. Developing the process required copious iteration and a high precision. https://images.squarespace-cdn.com/content/v1/6012c667333305652fe566f8/1614868791363-DN7E3ZOYPJEB1R3R8OEO/IMG_0659.jpg Grain Boundary Research - (1) 3D Print Master Master is generated using Stereolithography (SLA) 3D printing. The crystal is highly sensitive to the dimensions of the master. A cusp too large between the two crystals or too small will cause the crystal to leave the metastable region and form multiple grains. https://images.squarespace-cdn.com/content/v1/6012c667333305652fe566f8/1614868600584-L2CUVX7FOL3ZJCH3AXHB/molten-metal-in-crucible-5226099166.jpg Grain Boundary Research - (2) Cast plaster mold The 3D printed master is placed inside of the mold housing. Plaster is added then left to dry. Then, the mold is heated and the 3D printed master melts away.

The furnace (labeled in the image to the right) starts low to the ground and moves upwards at a rate of 1 inch per hour to grow the two aluminum grains in a controlled and repeatable manner. A vacuum pump is also attached to the furnace to lower the pressure in the crystal growth chamber to reduce crystal impurities. https://images.squarespace-cdn.com/content/v1/6012c667333305652fe566f8/1614913644465-RVL8TBJ8PWD5YS0TQ211/grain+boundary+3.png Grain Boundary Research https://images.squarespace-cdn.com/content/v1/6012c667333305652fe566f8/1614913617240-BRKLXWQ5FGX1WF9NS87J/grain+boundary+2.png Grain Boundary Research https://images.squarespace-cdn.com/content/v1/6012c667333305652fe566f8/1615652821179-EWENJX68B8AIPTYH24OR/grain%2Bboundary%2B6.jpg Grain Boundary Research After Machining https://images.squarespace-cdn.com/content/v1/6012c667333305652fe566f8/1615652785692-MDN7BLB83EBKOK2PFRHI/IMG_0661.jpg Grain Boundary Research Before Machining https://images.squarespace-cdn.com/content/v1/6012c667333305652fe566f8/1614917277043-0LD2GN2XT88FFPXYGL4J/IMG_0294.jpg Grain Boundary Research - (4) Machine bicrystal into required sample dimension Machining a bicrystal is more challenging that stock aluminum billets because the metal is softer and requires slower feeds and faster speeds.
