As we look up to the skies and witness the marvel of satellites orbiting our planet, it's easy to forget the complex science and engineering that make these missions possible. Today, We want to shed light on one of the unsung heroes of satellite development - Thermal Engineering. 🌡️ 🌟 Why is Thermal Engineering so essential in the world of satellite design and space missions? #space #consulting #satellite #cubesat #engineering #software #hardware #thermal

Traditionally, propellants for chemical rocket engines have been divided into two categories: cryogenic and storable.   While cryogenic propellants offer the highest performance and are non-toxic, they are only used for launch vehicles and other short-duration missions.   Storable propellants, such as hydrazine, can be easily stored for years, but are either highly toxic or offer only mediocre performance. But they are the only choice for long-duration space missions.   Our Cryogenic Propulsion Module could change all that.   The CPM's zero boil-off technology allows the cryogenic methane/oxygen propellants to be stored indefinitely in orbit. A passive Resonance Ignition System gives the system quasi-hypergolic properties, providing the ignition reliability critical for demanding multi-year missions. The self-pressurising system architecture eliminates the need for heavy and expensive pumps and eases thermal management. Finally, regenerative cooling allows the thrust chamber to deliver the highest possible performance without compromise.   These features allow the Cryogenic Propulsion Module to deliver kick-stage-like performance in a smallsat form factor, even years after initial deployment into orbit.   Our recent Hotfire campaign demonstrated that these are not empty promises. It showed that all the components work well together and can deliver the targeted performance. Even in its simplest breadboard version, it already delivers a specific impulse well above anything else on the chemical satellite propulsion market, and future improvements can only increase this advantage.   This puts the CPM in a prime position to serve the space logistics market of the future.

https://lnkd.in/gSjWHhQy having participated as a subject matter expert in multiple risk boards, i have learned a lot about how the boards assess risk, really a complex matriz of probality of occurrence of the specific chain of events that could cause the failure in the mission and consequence of the failure. this matrix covers all known facts of leaks in valvetech valves , leak rates akd acceptable leak rates. past events are also added. the probability calculations are math based but at the end of the day engineering judgement is thrown in to calculate the probability. "So here is my guess on the If-then statement... IF one single valve with the same workmanship as other valves leaks post-fights the current rate on the ground by 100 times and no corrections can be made, THEN there will be loss of life. " to be clear. this is my guess based on my engineering knowledge of spacecraft systems and These type of valves. these are NOT and never should be easy decisions.i am certain they are not, in this case. getting to the root causes that are verified and fixed is vital. really vital.

🛰️CUBESAT UPDATES The 6S CubeSat team has now entered phase C, which means they'll also be getting their hands dirty with some -not so dirty- testing! Let’s take a closer look at what this means! But first, a short review of the main components that this phase envisages. PESCA and VOLTA are the two payloads of the CubeSat. PESCA stands for PErovskite Solar Cell Analyzer: it’s a system that aims to evaluate the performances of the PErovskite Solar Cell (PSC); innovative solar cells - provided in partnership with the University of Potsdam and the University of Cambridge - that can theoretically perform 42% better than the regular ones. Whereas VOLTA is a structural battery that enables storing more electric power with the same values of mass and volume. During phase C, the design will be further refined to reach a final design of 6S that would satisfy the mission objectives. In fact, the mission objectives are achieved through testing VOLTA under the highest possible thermal gradient in five consecutive orbits and measuring key values of the PSC. PESCA will analyze the PSCs measuring their I_SC (short circuit current), V_OC (open circuit tension), Maximum Power point, the entire I-V curve and other important values like the temperature. The tests will be performed numerous times during the duration of the mission to collect enough data to be studied. The development of the testing phase will be strongly supported by the implementation of the Failure Mode and Effect Analysis (FMEA). This procedure is a bottom-up analysis that accounts for every failure mode and its effects on the mission. In this way, the testing becomes more reliable, also giving some hints of identification of potential mitigation actions. 🤩Are you willing to explore the 6S CubeSat and its secrets more in-depth?
