Systems Engineering Trends - News from the world of systems engineering every week ?? ?? Daniel Siegl recently organised a top-class discussion on the topic of SysML v2 conformance, which has now been published on the blog "Systems Engineering Trends - News from the world of systems engineering every week". The founder and author of the blog, Michael Jastram, spoke with Andreas Pollom (Fraunhofer IESE), Daniel Siegl, Robert Karban (co-founder of OpenMBEE and until recently at the NASA Jet Propulsion Laboratory) and Vince Molnár (assistant professor at the Budapest University of Technology and Economics). This panel was organised because SysML v2 compliance is currently in acute danger. If a solution to this problem is not found soon, this could be a major setback for SysML and MBSE. The victims will be the users who expect their work results to be interoperable. Therefore, the panellists appeal to the MBSE community to take action now and actively contribute to the work around SysML v2 conformity! The discussion was held in English (the video is available in part 1 of the discussion) and summarised in German by Michael Jastram.

I’m excited to announce my recent project with Zip Code Wilmington: the ?? 'Mars Lander' Simulation. This was a fantastic opportunity to revisit high school physics while developing a SpaceX Starship landing simulation in Java. Key contributions included designing the Vehicle class and the OnBoardComputer class to automate safe landings based on real-time telemetry. This project significantly enhanced my skills in simulation design and real-time systems. ?? ?? ?? https://lnkd.in/eqBys9en #Java #Simulation #SpaceX #SoftwareDevelopment #Physics

Using superfluid to study rotating black holes. Very interesting. I recommend checking out Sabine Hossenfelder's Youtube video for a high-level intro to the concept: https://lnkd.in/gJXcV2mM

My geeky way to wish a happy, prosperous and healthy Lunar New Year to all who celebrate this event under the auspicious sign of the Dragon. The dragon symbolizes great power. Power has the ability to make changes, and the duty to use it responsibly. It's a wonder how a bit of logic analysis and SPI programming brought this 101x80 256-colour LCD back to service. I couldn't get hold of the exact datasheet, though browsing the internet suggests that it resembles the Sharp LCD used in many mobile phones. A bit of logic sniffing helped retrieve the initialization sequence from the phone at start up. The phone was picked up from a recycling bin for free. There are too many useful things ending in land fills/incinerator because they appear obsolete (most of time by design!). I hope this new year of the dragon will urge us to switch to new paradigms of durable engineering through the power of knowledge and wisdom.

“What to do about space junk?” appears to be a significant emphasis for teams of high school students from MARYSVILLE STEM EARLY COLLEGE HIGH SCHOOL led by teachers Brooke Young and Mike Young. These students are engaged in the Ohio STEM Learning Network 2024-25 statewide design challenge based upon Starlab.?Students in two breakout rooms peppered space Experts Russell Kirk Pirlo of University of Dayton and John Trzinski of The Ohio State University with questions. Discussions ranged from initial design challenge approaches of “space nets” and “giant space vacuums” to “How to safely knock debris out of orbit so that it burns up in the atmosphere”. Team members probed Experts with questions such as “What is the materials composition of space junk?”, “How do we track space junk?” and “How are we ensuring that future objects launched into orbit do not contribute to space junk?”. Students will apply their learning and hope to share their concept-level solutions with Experts in a couple of weeks in the next interactive round! #STEM #DesignChallenge #WorkforceDevelopment

See you tomorrow morning at #ISSRDC where Joey Heying & I will be introducing the COSMIC Capstone Challenge as the COSMIC - The Consortium for Space Mobility and ISAM Capabilities leads for Workforce Development. If you can't make it in person, learn below how to register your university or sign up as a mentor. I’d like to invite you to participate in the inaugural COSMIC Capstone Challenge?(C3), a new?student?design competition to develop concepts for in-space servicing, assembly and manufacturing (ISAM). The?NASA-funded?Consortium for Space Mobility and ISAM Capabilities (COSMIC) was established?in response to the National ISAM Implementation Plan?in order to advance those capabilities in the United States. C3 is a unique offering that would benefit students studying aerospace, electrical, and mechanical engineering among other disciplines. Here are?some of the elements that may make this a good fit for your students: * Project focus on the conceptual design phase, which can benefit from the fresh insights of engineering students * Weekly or biweekly mentoring from a dedicated industry expert already working in the ISAM field * Ability to work in a cutting-edge area, exposing students to new concepts and positioning them well for future employment in related fields * The 2024-25 challenge asks?students to create a conceptual design for ISAM demonstration mission * By leveraging the COSMIC network, great ideas could be developed further and fly early next decade * The detailed C3 Information Packet?has been developed to guide students through the process, which includes dozens of references and recommended milestones * While structured primarily for design classes of college seniors, any student team is eligible which could include directed study, student clubs, high school teams or even independent study * All entrants will present to professionals at a 30-minute outbrief in mid-April (with a back-up option in June) * Monthly seminars from experts in ISAM and other pertinent fields ? And much more. If you’re planning to offer this to your students, I encourage you to register your school. And once students have formed their teams, they can sign up?here. You can reach out to the organizers, (Joey Heying & Jacob Rome, who are organizing this effort as the COSMIC Workforce Development co-leads) with any questions at [email protected]. Or visit https://COSMICspace.org/c3 & download the info packet. ?

This week marked the third lunch of space X starship super heavy, this marks another major engineering achievement and major milestone for the space x team and the space exploration industry . What you are seeing is star ship itself without the booster re-entering earth atmosphere at hypersonic regime />5xspeed of Sound, at this speed air doesn’t have enough time to flow round the vehicle’s path so the build up of plasma occurs because of the intense compression of air particles as you can see by the noticeable glow on the sides of the vehicle. Now as a young engineering student aspiring to become an engineer, I’m always curious about invention and innovations that reshape our world and help those in need through the apple of knowledge, cause what i believe in is the gift we are born with was given to us help others, to help those who can’t help themselves, that’s why I ensure I acquire the tools needed like learning engineering concepts like 3d deigns, simulation manufacturing and testing and also understanding from first principles, all in effort to make the world a better face, to put a smile on your face ?? #spaceexploration #spacex #engineeringdesign #designengineering #rocketscience #industrialdesign

Important Dates in Engineering History: March 16, 1926, Auburn, Massachusetts, was the chosen location for renowned physicist Dr. Robert H. Goddard's historic launch of the world's first liquid-fueled rocket on March 16, 1926, an event that marked the beginning of man’s journey into space. Goddard's rocket design was significantly different from earlier solid-fueled designs because it used liquid fuel, which allowed for greater control and efficiency in propulsion. This first liquid-propelled rocket reached an altitude of about 41 feet (12.5 meters) and traveled a distance of around 184 feet (56 meters) in 2.5 seconds, eventually landing in a cabbage field. It was a modest first step. Goddard's rocket, named Nell, incorporated several innovative features: it had the engine on top and the fuel tanks below, a setup that Goddard thought would make it more stable. Additionally, it included a combustion chamber, a nozzle, and a system for fuel and oxidizer delivery. His rigorous calculations and propulsion experiments influenced future pioneers like Wernher von Braun and inspired breakthroughs that led to space missions, satellite launches, and crewed spaceflights. Goddard, one of the great pioneers of rocketry, ignited the imaginations of scientists, engineers, and visionaries worldwide, and influenced generations of thinkers in fields from engineering to filmmaking. #RocketryHistory #InnovativeRocketDesign #AerospaceWelding #HighTechWelding #PrecisionWelding #ElectronBeamWelding #AdvancedWeldingTechniques #WeldingForSpaceIndustry #AerospaceManufacturing #WeldingSolutions #WeldingTechnology #AerospaceEngineerin #ElectronBeamTechnology #AdvancedManufacturing #WeldingExpertise #WeldingCapabilities #AerospaceInnovation #PrecisionWeldingSolutions #WeldingForHighTechIndustries #SpaceTechWelding #WeldingInAerospaceg #ElectronBeamWeldingExpertise #AdvancedWeldingProcesses #AerospaceManufacturingExpertise
