Perfection is a nice word! but after doing a workshop with an ex NASA Engineer about prototyping I learned this quote! Better done than perfect: If it is done you can improve it if not you must do it. after that everything is a learning path for me. "ON" is a trigger at the end of the word. Take a look. Is like Igniti"ON" Is like passi"ON" is like Stati"ON" is Like Acti"ON" All what requires you movement has an ON at the end. Which one is your trigger? 😜 #frankperaltatherenewablefashionguy #SustainableDesign #AutomotiveLeather #sustainability #design #upcycling #sustainability #innovation #renewableenergy #innovation #tech

NASA to design sustainable jet engine core by Clarence Oxford - Los Angeles CA (SPX) NASA, in collaboration with industry partners, is set to design a new jet engine core for ultra-efficient airliners, moving into the project's next phase. In its pursuit of sustainable aviation, NASA is developing a small core for a hybrid-electric turbofan jet engine aimed at reducing fuel burn by 10% compared to current engines. A jet engine's core mixes compressed air with fuel to generate power. By reducing the core's size, fuel efficiency can improve, and carbon emissions can decrease. The Hybrid Thermally Efficient Core (HyTEC) project aims to demonstrate this compact core and prepare the technology for next-generation aircraft in the 2030s. HyTEC is a significant part of NASA's Sustainable Flight National Partnership. HyTEC's structure includes two phases: Phase 1, concluding now, focused on selecting technologies for the core demonstrator. Phase 2, starting now, will involve designing, building, and testing a compact core with GE Aerospace. "Phase 1 of HyTEC is winding down and we are ramping up Phase 2," said Anthony Nerone, who leads HyTEC at NASA's Glenn Research Center in Cleveland. "This phase will culminate in a core demonstration test that proves the technology so it can transition to industry." Before starting the design and build process, researchers explored innovative materials for the engine. After three years of rapid progress, HyTEC researchers found solutions. "We've been laser-focused since day one. We began the project with certain technical goals and metrics for success and, so far, we haven't had to change course from any of them," Nerone said. To reduce core size while maintaining thrust, the core must endure higher temperatures and pressures. Thus, more durable materials are essential. https://lnkd.in/diw7kVbw

We are thrilled to announce that Spartan Space, in collaboration with LIQUIFER Systems Group GmbH, has been working on a contract from German Aerospace Center (DLR) to contribute to the development of the Lunar Agriculture Module – Ground Test Demonstrator (LAM-GTD). For the project we have been working on pre-design and development of the Greenhouse Ground Demonstrator involving two critical structural modules: 🔹 The Logistics / Agriculture & Life Support Module 🔹 The Airlock Module These modules will play a vital role in simulating operations on the Moon, supporting life support systems and advancing space agriculture technologies.

Dehumidification: A Critical Step Before SpaceX Rockets Launch Before a SpaceX rocket is ready for liftoff, there's an essential, often overlooked step: dehumidification. At the Climate by Design International factory in Owatonna, MN, specialized low dewpoint desiccant units are crucial in creating the precise, dry environment needed for rocket preparation. With strict humidity control, moisture could protect the rocket's sensitive satellite equipment and components, jeopardizing mission success. CDI's advanced technology ensures that the rocket's interior is dried to the lowest dew points, supporting NASA and SpaceX in their quest for flawless launches. This meticulous control prevents condensation and safeguards the integrity of every part, from the most miniature circuits to complex satellite assemblies. Dehumidification isn't just a backstage process—it's an unsung hero in the countdown to launch, helping to make each mission possible. At CDI, the team takes pride in knowing that their expertise helps aerospace pioneers reach new heights. Watch the full episode on HVAC TV Here: https://lnkd.in/eUqdz82a

LIQUIFER‘s latest cooperation with Spartan Space for the Deutsches Zentrum für Luft-und Raumfahrt e.V. In Bremen, Dr. Daniel Schubert is the lead for this greenhouse ground test demonstrator. It is an international cooperation with the Canadian Space Agency.

🚀 Watching the final flight of United Launch Alliance (ULA)'s Delta IV Heavy inspired me to learn more about Aerojet Rocketdyne's RS-68A, which is a prime example of balancing performance, affordability, reliability, and manufacturability. 🚀 Here are a few ways RS-68 compares to RS-25 (which served as Space Shuttle Main Engines and now powers NASA's Space Launch System): **not intended to be an exhaustive list 1️⃣ Simplified Design: RS-68 achieved approx. 80% reduction in unique part count compared to RS-25. This reduction is parts directly translates into: - Ease of manufacture: the number of hours of touch labor required to manufacture the engine - Reduced total cost – material, labor, supply chain simplicity, inventory, transportation, etc. - Fewer parts also means fewer potential points of failure during the mission 2️⃣ Open Cycle vs. Closed Cycle Architecture: RS-25 SSME's architecture utilizes fuel-rich staged combustion closed cycle where separate “preburners” are used for LH2 and LOX. Their hot, high-pressure exhaust gas is driven through the turbopumps and into the main combustion.  Conversely, RS-68 utilized a much simpler open cycle architecture where portion of propellants is combusted in a gas generator and its exhaust is run through a turbopump and vented overboard. 3️⃣ Nozzle Cooling: RS-25 SSME used regenerative cooling where LH2 was circulated through nozzle walls, which makes engineering and manufacturing much more complex. Conversely, RS-68 used much simpler ablative cooling which is designed to absorb heat and gradually erode in a controlled manner. 4️⃣ Human-rating: RS-68 engine was NOT human-rated and was primarily designed for unmanned launches. Human-rating an engine requires additional modifications to meet stringent safety and reliability standards. 5️⃣ Combustion Chamber Pressure: RS-25 chamber pressure was close to 2994psi which contributed to its higher efficiency and performance. Conversely, RS-68 operated at a much lower 1488psi which most likely simplified material selection and manufacturing methods, and reduced the overall cost. 6️⃣ Design for single-use vs. reuse: RS-25 was designed for reuse, but RS-68 was optimized for single use. This factor likely influenced certain material choices and overall architecture. ⚙️ So what were the resulting performance tradeoffs? RS-25 has a thrust-to-weight ratio of 73.1 compared to RS-68 at 51.2. This means RS-25 is much more efficient in terms of thrust produced per unit of its weight. Another critical performance measure for a rocket engine is Specific Impulse (Isp), which represents the amount of thrust produced per unit of propellant consumed. In vacuum, RS-25 was much more efficient with Isp of 452 seconds compared to RS-68 at 410seconds. But at sea-level they both were very close. RS-25 at 366 seconds and RS-68 at 365 seconds. #designformanufacturability #designforreliability

NextSpace ... "LEVERAGING IN-SITU RESOURCE UTILIZATION (ISRU)- The SpaceFactory-MTU project brought forth several innovative engineering strategies designed to maximize the utility of lunar regolith, an abundant resource on the moon's surface. A key innovation lies in the development of a novel material, referred to as lunar 'asphalt,' engineered specifically for the lunar environment using regolith and biopolymers. The process was carried out by a robotic apparatus that performed the construction tasks in vacuum, laying and heating the lunar asphalt into a dense, cohesive surface capable of withstanding the mechanical stresses of lunar vehicle traffic. The team demonstrated the material's durability by driving a simulated lunar rover wheel over the road 900 times, covering 720 meters. Significantly, the durability test revealed no dust accumulation on the wheel, highlighting a significant advantage of our patent-pending technology."
