LPL in 2017 was a new mobile test stand (Hydra). I oversaw the design of Hydra’s original feed system and led the procurement and fabrication. Hydra is now operational, fired multiple rocket engines, and is a key enabler of training incoming members. I was a co-author of a publication about this test stand that was presented at the 2018 AIAA Propulsion & Energy Conference. https://images.squarespace-cdn.com/content/v1/5c639f2e11f78440d05623e3/1550883938688-D3JPXLR1XKUP82UOWWV7/IMG_3023.jpeg Hydra Mobile Test Stand https://images.squarespace-cdn.com/content/v1/5c639f2e11f78440d05623e3/1550882923064-HM4DZZBCNROIEXLOYWUC/Screen+Shot+2019-02-22+at+4.47.25+PM.png Hydra Mobile Test Stand https://images.squarespace-cdn.com/content/v1/5c639f2e11f78440d05623e3/1550882932075-OGDGNT1PHHVTURQDTGO9/Screen+Shot+2019-02-22+at+4.47.35+PM.png Hydra Mobile Test Stand https://images.squarespace-cdn.com/content/v1/5c639f2e11f78440d05623e3/1550882952834-9GWOUAOZPINA7HSBZ7KY/Screen+Shot+2019-02-22+at+4.47.43+PM.png Hydra Mobile Test Stand https://images.squarespace-cdn.com/content/v1/5c639f2e11f78440d05623e3/1550882990061-KJG4DHV7KVZ9BDDEU77T/Screen+Shot+2019-02-22+at+4.47.51+PM.png Hydra Mobile Test Stand https://images.squarespace-cdn.com/content/v1/5c639f2e11f78440d05623e3/1550884123403-JS5F31RMTFK3WJ5XIHZ0/1K9A7257.jpg Hydra Mobile Test Stand https://images.squarespace-cdn.com/content/v1/5c639f2e11f78440d05623e3/1551147810995-8F2B5CJERQKHGS7Z51BM/Screen+Shot+2019-02-25+at+6.22.43+PM.png Hydra Mobile Test Stand https://images.squarespace-cdn.com/content/v1/5c639f2e11f78440d05623e3/1550811795290-M992JFIRP6AQCD0NGSLL/hydra-pic1.PNG Hydra Mobile Test Stand https://images.squarespace-cdn.com/content/v1/5c639f2e11f78440d05623e3/1550363451153-ZKNKGR3SZ7PBZPDSRMJ0/IK3A9100.jpg Hydra Mobile Test Stand https://www.johntargonski.com/spacex-1 daily 0.75 2019-03-07 https://images.squarespace-cdn.com/content/v1/5c639f2e11f78440d05623e3/1551736084924-MKKN1ZO9VOYWB36Z91FU/custom-electronic-enclosures-500x500.png SpaceX Merlin Rocket Engine *Not SpaceX work, for reference https://images.squarespace-cdn.com/content/v1/5c639f2e11f78440d05623e3/1551577470624-DF7BO618RGZUV6KMUDYW/100th_m1d_4_engine28.jpg SpaceX Merlin Rocket Engine https://images.squarespace-cdn.com/content/v1/5c639f2e11f78440d05623e3/1551577482586-RO68NO8RD5MRDDDH61WA/M+1D.png SpaceX Merlin Rocket Engine https://images.squarespace-cdn.com/content/v1/5c639f2e11f78440d05623e3/1551730612352-TB3S4GWTKNNQP1KX16XO/Screen+Shot+2019-03-04+at+12.16.21+PM.png SpaceX Merlin Rocket Engine Source: Yaskawa America *Not SpaceX work, for reference https://images.squarespace-cdn.com/content/v1/5c639f2e11f78440d05623e3/1551575227266-V49D2QTUK9R7D7Z3VDQY/IMG_1269+2.jpeg SpaceX Merlin Rocket Engine Summary As a member in the Turbomachinery Development group, I was fortune to work on Rocket Engine Programs that were both near completion & in initial development, with the Merlin & Raptor Engines.

The engine(s) went from conception to full fabrication and assembly in 4 months. Today they serve as LPL’s workhorse engines to be developed upon and learnt from for years to come. https://images.squarespace-cdn.com/content/v1/5c639f2e11f78440d05623e3/1550702118294-D8AYBCW5HJM6N0UP7P85/SMC%2BTehreem%2BRaza%2B-25.jpg Copy of Jessie & James Rocket Engines https://images.squarespace-cdn.com/content/v1/5c639f2e11f78440d05623e3/1550087784730-A5C4WKUAJP7SNQMU0IQA/Jessie_James_crop_render.jpg Copy of Jessie & James Rocket Engines - Copy of Jessie & James Engine A computer-aided design, CAD, rendering of the Jessie & James Engine https://images.squarespace-cdn.com/content/v1/5c639f2e11f78440d05623e3/1550609547574-Z1GIFN0XT2HFPRMPP721/Jessie_cut.jpg Copy of Jessie & James Rocket Engines - Copy of Simplicity A cross-section that illustrates the 5 main components that make up the engine https://images.squarespace-cdn.com/content/v1/5c639f2e11f78440d05623e3/1550554165860-0UENKNO8EDK9E5D6B2NE/IMG_0825.png Copy of Jessie & James Rocket Engines - Copy of Elegance Showcases an ascetically pleasing design with a minimal number of components. https://images.squarespace-cdn.com/content/v1/5c639f2e11f78440d05623e3/1550609464353-8D8GI4PMNYK6WKEKIE8Q/Screen+Shot+2019-02-18+at+9.34.01+PM.png Copy of Jessie & James Rocket Engines - Copy of Exploded View An exploded view that shows the orientation of all primary and secondary components featured on engine. https://images.squarespace-cdn.com/content/v1/5c639f2e11f78440d05623e3/1550609471627-349CQICBS5CN1C501MTB/Screen+Shot+2019-02-18+at+9.35.38+PM.png Copy of Jessie & James Rocket Engines - Copy of Modularity One example of modularity.
