Liftoff!!! Last Friday we successfully launched AQUILO VIII.5S. One year ago, AQUILO Rocket Team attempted to #launch AQUILO VIII, unfortunately due to an overpressure in the #motor, this resulted in a very rapid unscheduled disassembly and thus the loss of months #work.  During the summer holiday, the team solved the design issues and improved their #propellant casting skills. The new launch opportunity: March.  But, due to a procedural #error, the rocket still didn’t come off the launch tower, another hard #lesson learned. However, there is one thing this team won’t do: giving up. The last few months the team worked on extensive checklists including every step from our university to the launchpad. After multiple practice assemblies, we included every step in our procedures. So we filled the #motors with grains from the largest propellant #casting we have ever done and we were ready for the launch. 3. 2. 1. Ignition! And what an #ignition it was, the rocket took off, almost instantly, in a straight line towards 1100+ metres. This was a well deserved launch after years of #improvements (more detailed information at Jondar Hoenselaar’s page). This all, together with a successful motortest, resulted in an amazing victory for the whole team. Actually all teams and amateur organisations successfully launched their rockets. It was especially nice to see that the teams were even collaborating on such events. More on this later. Thanks to this amazing team and all the people who helped to make this possible. In thrust we trust!

F-22 RAPTOR ENGINE START AND TAXI 🇺🇸 See the flame coming out of the APU or auxiliary power unit upon startup. TY on the tail signify’s Tyndall AFB in Florida. The APU is first turned on in order to then start the main F119 engines producing 35,000 pounds of thrust each. The power to weight ratio is 1:1.

This elastomer jaw coupling, GN2240 has been used in a student project, creating a flight simulator! These couplings, from Otto Ganter GmbH & Co. KG can transmit very high torques while compensating for shaft misalignments and runout tolerances. They are preferred in applications where the focus lies on pure torque and power transmission. The choice of three coupling spiders with different hardness values allows the properties of the coupling to be optimally matched to the specific requirements. The clamping hubs and simple plug-in installation make jaw couplings very easy to assemble. #Couplings #FlightSimulation #Training #Studentimagination

There was a time when Stephen Hawking’s predictions were greeted with skepticism. (Not surprisingly, as it also happened to Newton). However, over the decades, they have been proven—almost all of them, except one that seemed impossible. Do you know which one we are talking about? The physicist never believed in combustion engines and pointed to something very different: the detonation engine. A group of engineers has created the first one, with a prototype that works, breaking the laws of the universe. #propulsion #detonation #engine #prototype #hawkings https://lnkd.in/gffhQjRZ

In the deeper essence of quantum mechanics, this will cover the nature of reality.

SPST was the innovation of Rocketry propulsion development of solid propellant motor or propellant,The main Aim of the project is to develop re-landing vehicles by using solid,liquid or cryogenic propellants.

R E V V O L U T I O N 1.5🏎 Hello everyone, I'm beyond excited and happy to announce that the free 1.5 update for my realistic engine synthesis suite for Kilohearts AB Phase Plant is out now! It is the result of over half a year of refining the synthesis and, most importantly, trying to make the usage as straight-forward as possible. Aside from new engines and functionality (even for existing ones), it features an updated user guide/tutorials as well as a template preset with "advanced" functionality pre-setup, hopefully allowing everyone to understand the synthesis and build their own engines. To celebrate the launch, there is a 20% discount when using the code 1V5 upon checkout until the end of the week (Sunday, May 12th, 12:59 PM CEST). Hope you enjoy! :) P.s: My reach is 100% limited to the word of mouth, so if you think it's worth it, I'll be beyond thankful for every share/"spreading the word" in general! https://lnkd.in/efYFW9YM

Cadence Fidelity CFD AutoMesh provides an uncomplicated way to create or reposition the RS interface. The stator geometry is extended by the required areas and the mesh setup is automatically adapted to the rotor meshing. Let Patrick Shoemaker inspire you in our latest Lifehack.

I love stories like this. 4 college kids beat a bunch of defense giants in a drone-killing tech competition using a device they made in a backyard! Here's how they did it... The idea for their drone-destruction tech came over a cup of tea. 🫖 Anna & Parth wanted to compete but couldn't afford traditional weapons. Instead, they decided to target drones with sound waves. Resonance frequency became their secret weapon. Imagine shattering a wine glass with sound—now imagine doing that to a drone. 🍷💥 That's how these students approached the challenge. Built with an old car speaker in a backyard, their device used ultrasound to knock drones out of the sky. After testing, it worked well enough to invest in better technology. They eventually spent $17K on speakers and hardware, racking up $9K in credit card debt before the competition. When they showed up to the competition, all the other teams had fancy SUVs and team swag. Undeterred, the students placed second out of fifteen teams, including defense giants like Boeing and Teledyne. The students left with $270k of prize money. Haters will complain about the physics of sound waves and how the technology isn't ready for the field. So what! It's awesome that a bunch of students competed and beat these big companies. What's next? They're starting a company called Prandtl to commercialize the technology. https://prandtl.ca/ Follow their story on LinkedIn:  https://lnkd.in/g4Fe4piP https://lnkd.in/gQ2Kssfj https://lnkd.in/gvxkwFcs
