11 2016 Project Overview 11

12 Project #1 Additively Manufactured Heat Exchanger Lockheed Martin designs and builds many computer assemblies. These computers utilize circuit card assemblies that consist of various electrical components that can get very hot during a mission. Heat exchangers are used to remove the heat and safe-guard the components. These heat exchangers can be expensive to produce using traditional manufacturing methods. Redesign an existing heat exchanger for AM Choose a proper AM process and material for the heat exchanger Cost and build time must be taken into account Sample part can be built using plastic additive technology, but differences in design between plastic-built part and actual part should be reported Overall size factor must remain as-is and CCA Mating features must remain as-is Internal air-flow thru geometry can change, but surface area must remain constant. 12

13 Project #2 Sensitive Payload Shock Absorber Lockheed Martin has several unmanned aerial vehicles (UAVs) that experience high shock loads upon landing. These UAV parts must be as lightweight as possible yet strong enough to handle the harsh landing conditions. Develop an internal member to transfer and distribute the shock loads from the tail to the elevator. Structure should be able to handle multiple landings Bending moments will be acting on the lever and fastener holes. Additively built structures are preferred due to scheduling Bonus points for structures that could be built in theater The lighter the structure, the better. Less weight means the UAV can carry more payload and fly longer Structure must fit within provided volume 13

14 Project #3 Connecter Backshells Wire harnesses and connectors are a universal challenge throughout Lockheed Martin s product lines. We currently procure backshells from connector manufacturers, and these current backshells limit our ability to separate signals coming out of the electronic assemblies and into the harness. Another issue with the current backshells are the internal sharp edges. Internal sharp edges can abrade and damage the wiring and cause signal loss from assembly to assembly. Develop custom backshells that have the ability to efficiently separate signals coming out of the electronics assembly and into the harness as well as provide smooth internal surfaces removing any concern of wire abrasions. Develop and design: Single port Multi-port backshells Multi-port design would be to provide the ability to separate the signals coming out of the harness Backshells must be compatible to micro-d or D-sub connectors (MS24308 & Mil-DTL ) Backshell exit orifices shall have features to install band clamps once the harness has been installed Backshells must prevent wires from experiencing chaffing on the internal part of the backshell that would lead to wire damage and signal loss 14

15 Project #4 USB Hub Mounting Bracket Due to a design requirements change a new USB mounting bracket needs to be designed From a 4 port hub To a 7 port hub From Horizontal mount To Vertical mount New cable retention for usb cables and power From single usb hub to stacked 3 high Environment 0 to +25C Must show that new bracket can survive vibration loading Old Hub and Bracket New Hub 15

16 Project #5 Design for Additive Lockheed Martin design teams have relied upon traditional methods of manufacturing (casting, machining, etc.) to solve our complex and complicated problems. As additive manufacturing continues to mature in quality and capability, our engineers must not only learn to use these techniques, but also learn how to design solutions to take advantage of additive manufacturing s unique capabilities. The future lies not in additively manufacturing a screw, but rather designing and additively manufacturing a system that doesn t need screws. Research a part or component that reflects the products that Lockheed Martin provides to our customers. Review your selection with Lockheed Martin representatives before proceeding with design. Redesign that part to take advantage of the capabilities of additive manufacturing. Create a prototype of your new part out of plastic using a 3D printer. Demonstrate that your new part meets or exceeds the capability of the legacy design while providing one of the following: Reduced weight Reduced part count Faster / easier assembly Improved performance 16
