A full session was devoted to initial technology evaluation flight campaign results for the SENS4ICE project at the 𝗚𝗲𝗿𝗺𝗮𝗻 𝗔𝗲𝗿𝗼𝘀𝗽𝗮𝗰𝗲 𝗖𝗼𝗻𝗳𝗲𝗿𝗲𝗻𝗰𝗲 (𝗗𝗟𝗥𝗞 𝟮𝟬𝟮𝟯) held in Stuttgart, Germany, on 19-21 September 2023. The results were presented by the team of German Aerospace Center (DLR). The project coordinator Carsten Schwarz provided a project overview highlighting the recent flight campaign activities and results. The core topic of indirect ice detection as part of hybrid ice detection was presented by Christoph Deiler. Johannes Lucke detailed the meteorological conditions and microphysical properties that lead to aircraft icing as observed during the SENS4ICE campaigns. One of the SENS4ICE direct ice detection technologies was described by Martin Pohl: LILD – Local Ice Layer Detector. The aerospace community and stakeholders were well represented in the audience and the SENS4ICE results were well perceived. It became clear that the SENS4ICE project opens the path towards safer aviation in icing conditions.

I am pleased to share with you the paper I presented at EUCASS 2023. The paper aims to describe the generation of an AeroThermal DataBase (ATDB) and discuss representative flow field topologies, and resulting surface heating patterns, developed during the re-entry flight of a Single Stage To Orbit (SSTO) Reusable Launch Vehicle (RLV) called RETALT2. This launcher configuration was designed in the framework of the Horizon 2020 project RETALT (Retro Propulsion Assisted Landing Technologies), whose main objective was the investigation of technologies for reusable launch systems.

Performance: Our solid rocket motors are THE most reliable assets for the nation's never-fail next generation missile defense missions.

All days in 2023 were more than 1ºC above the pre-industrial level. 2023 marks the first time on record that every day within a year has exceeded 1°C above the 1850-1900 pre-industrial level for that time of year. Close to 50% of days were more than 1.5°C warmer than the 1850-1900 level, and two days in November were, for the first time, more than 2°C warmer. https://lnkd.in/dKsdcwrT

Sustainable air travel?✈️ With a hydrogen-powered cryogenic aircraft engine, it could be done! With the ASuMED project, Demaco, together with an experienced consortium, developed a superconducting cryogenic aircraft engine. This engine, based on the dual cryostat concept, i.e. it contains two separate cryostats and two separate cooling systems. Furthermore, the rotor is cooled with liquid helium and the stator with liquid hydrogen. During this project, it was demonstrated that a compact and superconducting electric motor can absorb enough energy for application in the aerospace industry.

The challenges of steering a hypersonic plane - At five times the speed of sound a craft flies through plasma, not air. “Steering hypersonically using conventional control surfaces, like wings and ailerons, is out of the question. The forces and heat involved would destroy them. Smaller versions called trim tabs can help a bit. But what is really needed is a different approach. And, as he told delegates at last week’s meeting of the American Association for the Advancement of Science in Denver, Hisham Ali of the University of Colorado, Boulder, is one of those proposing just that. He thinks the answer is to be found in a field called magnetohydrodynamics.” “Aerodynamics manipulates gases. Magnetohydrodynamics manipulates plasmas. These are gas-like fluids whose atoms have been ionised by losing some or all of their electrons—as happens to the air, by frictional heating, when an object travels hypersonically through the atmosphere. Since a plasma’s particles are electrically charged (the electrons negatively and the ions positively), their flow pattern over a hypersonic vehicle could be altered using a set of electromagnets within. Changing the plasma flow would also change the craft’s trajectory, at a rate controllable via the electromagnets. Additionally, the plasma’s passage could be harnessed to produce electricity inside the craft, perhaps powering the magnets.” https://lnkd.in/gMzNB-Ma from The Economist

Ion propulsion systems, also known as ion thrusters or ion engines, are advanced forms of electric propulsion used in spacecraft. They create thrust by generating a cloud of positive ions from a neutral gas, which is then accelerated using electricity. Ion thrusters can be categorized as electrostatic or electromagnetic. These systems offer advantages like higher efficiency, lower fuel consumption, and longer spacecraft lifespan. They have been used in missions such as NASA's Dawn and the European Space Agency's BepiColombo, highlighting their potential for future space exploration. https://lnkd.in/eNrUYnmc #galaxyaerosgh #space #spaceexploration #SpaceNews
