The rapid development and testing of Ursa Major's Draper engine not only outpaced our original production timeline but also outpaced industry standards. Draper's propulsion system is more than qualified to address the US Government Accountability Office's growing modernization and supply chain concerns. https://brnw.ch/21wKXuv

The SD11487 is a half bridge configuration with two 1200V 12mΩ SiC MOSFETs. Also included in the module are two freewheeling 1200V SiC Schottky diodes in parallel with the MOSFETs and an integrated NTC temperature sensor. Continuous drain current is specified at 95A.With operating temperatures of -55°C to 175°C, the SD11487 is designed for the most demanding applications such as down hole exploration; space; and avionics. The hermetically sealed copper package combined with the Alumina Nitride direct bond copper substrate provide excellent thermal conductivity as well as case isolation. The integrated temperature sensing enables high level temperature protection.

This is a “two-fer” transmission. The first recording features Orbit Fab's Co-#Founder & CEO Daniel Faber. His journey is a fun one. Before settling on developing the "Gas Stations In Space" business case, he first looked at starting a space commodities exchange, even a space #Olympics event. This is a fun one. The second is from Colorado Spring, Colorado where the Space ISAC hosted the Value of Space Summit. I moderated a panel discussion on "Critical Challenges to Protecting Human Habitats on Orbit, on The Moon, and Beyond" with Axiom Space's Director, In-Space Infrastructure & Logistics Jason Aspiotis and the Space-ISAC's new Board Chair Samuel Visner. This wasn't just your regular security chat. We focussed on threats to value, because in-space human habitats are a capital intensive endeavor that needs de-risking. #Space #defenseindustry #ISS Christopher Hearsey, David Marsh, Colin Carroll, Alex Ioskevich, Geoffrey Baugh, George Pullen, Jeffrey Kaczmarczyk, Jeffrey Manber, Jeffrey Hill, Trudi Hoogenboom Ph.D, Michael Webster, Richard Phillips, David Berger, Rich Ferguson, Brian Karas, John Beckner, Rod Pirniakan, Leonardo A.

Propulsion is deeply integrated into nearly every facet of our lives, from enabling air travel and launching satellites that support the smartphones we carry to influencing countless other daily activities. Take an in-depth look at Ursa Major, a Colorado start-up and Harpoon Ventures portfolio company that's changing how propulsion gets into the hands that need it most to have a global impact. Ursa Major is the leading independent rocket propulsion provider and a critical player in building the space-industrial base in the United States. As the first American company to fire and fly an oxygen-rich staged combustion engine, Ursa Major provides reusable, high-performing propulsion systems to commercial space enterprises, defense contractors, and the Department of Defense for launch, hypersonic, and national security missions. The company employs the country's leading propulsion experts at its one-of-a-kind headquarters in Berthoud, Colorado, which houses engineering, manufacturing, and test operations all in one campus. Ursa Major’s first propulsion system, Hadley, is a 5,000 lbf ox-rich staged combustion liquid rocket engine that powers multiple hypersonic test programs in the Multi-Service Advanced Capability Hypersonics Test Bed (MACH-TB) program. Ursa Major now applies its expertise to solid rocket motors to bolster the industrial base and provide propulsion where the nation needs it most - national security and deep space travel. https://lnkd.in/gpvi4Zja

SME with 30 years of leadership in avionics, solid rocket motors, ordinance, and mechanical systems for rocket systems.
https://lnkd.in/gVe6MPim i often heard in my reviews of design and process risk evaluation efforts that my experience with all these failures modes that these are not common. see the table in the article.i have seen before . some examples of mine listed below are from about a decade ago: a. paschen's law and wire arcing from wire nicked during process of stripping of insulation showed their weakness. b. the emphasis on proper selection of connector and cable wire esp for extreme shock and thermal environments , hot and cold, something has kept me and my friends awake. c. one last point on Paschen's law. tin whiskers formed on lead free avionics can and do cause electrical shorts in space env. seen for third stage fight events. my big concern is , @ the end what amd how to capture the lessons learned and how to not forget those. Or, as someone suggested to me recently " lessons learned are overvalued, each team must learn these Over Again" Do you agree? #reliability #aerospace
