Today's newsletter looks at #GaN, #GaAs & #SiGe, including John Oncea's look at how GaN is improving space exploration. In addition, Rohde & Schwarz explains how correlated time-frequency measurements aid early development in optimizing gate driving and reducing electromagnetic emissions and Qorvo, Inc. tells you all you need to know about GaN technology. https://lnkd.in/eTfXuu5B

What if components in aircraft could morph in response to their external conditions, much like a bird changes the shape of its wings? And what if those components could function like an octopus arm, operating independently of a central control system? Inspired by these natural phenomena, ME Associate Professor Andres Arrieta, MSE Professor Rodney Trice, and their research team are developing morphing systems for hypersonic vehicles that respond to their environment. The goal is to create a surface that can take on a variety of shapes so the aircraft can maintain optimality over a range of speeds, temperatures and altitudes. ? Learn More:?https://bit.ly/3TBJOWJ

How do airplanes fly? It's a simple question, with a not-so-simple answer. Associate Mechanical and Aerospace Engineering Professor Craig Merrett recently worked with The Conversation US to explain how airplanes work in basic terms for its Curious Kids series.

In reflecting on past experiences in the aerospace engineering industry, I pondered the significance of "trajectory." It's the path of development that resonates with us all, each on a unique journey with unknown variables. Whether in space or in life, we start with what fuels us towards our destination. What's fueling your rocket today? What path are you embarking on? The journey is intriguing; take that leap and discover where you'll soar!

At Space Technology and Aeronautical Rocketry, each day we are getting a step closer to Space. There are a lot of uncertainties about using COTS in space. We are developing a sounding rocket named KALAM to open the window of Space for students. KALAM uses COTS components for electronic systems to reduce the launch cost. P.S. - This is a fully functioning PCB as a prototype. Future PCBs will be more compact and will be built with redundancy.

??? We've been developing Elodin's next major feature, a framework for developing flight software. We call it ROCI – either named after the ship in the Expanse or a backronym for Rust Object Component Interface. ROCI allows users to develop flight software quickly, test it against simulations, and then move it onto real hardware faster than ever before. We recently integrated our attitude determination system, built with ROCI, into a customer satellite. Below is a demo of us testing that satellite running ROCI and using Elodin as a real-time visualizer.

Launch summary: Within just an hour of deployment by MCC, our team was able to recover our rocket, Invictus, guided by the Big Red Bee GPS to its general location. We were relieved to find the rocket intact, thanks to its distinctive red and white main chute. Remarkably, despite the higher impulse of the new M6000ST propellant, which nearly doubles our previous propellant's force, the rocket suffered no significant damage and would have been able to be prepped for another launch on the same day. As a result, our team sees this as a success considering our successful flight and quick recovery, and we are now prioritizing closer monitoring of our rocket's surface finish to optimize performance and ensure consistent achievement of target altitudes, regardless of the propulsion system used in future missions.?? #spaceportamericacup #rocketry #rocketlaunchers #aerospace #utrgvcecs?? #engineering #team UTRGV College of Engineering & Computer Science

What is the tyranny of the fairing? The fairing refers to the nose cone or payload fairing of a rocket that protects the payload during launch. It is shaped like a cone due to aerodynamic considerations. The size and shape limitations of the fairing place constraints on the size of payloads that can be launched. This is referred to as the “tyranny of the fairing” – payloads have to be designed to fit within these restrictive fairing dimensions. https://lnkd.in/e6NG5USN

Aerodynamics is the study of how gases, especially air, interact with moving objects. This field is central to understanding and designing vehicles like airplanes, cars, rockets, and even sports equipment. Aerodynamics examines forces such as lift, drag, thrust, and weight, which govern an object’s behavior in flight. #Aerodynamics #FlightPhysics #AviationScience #AirplaneTakeoff #LiftAndDrag #ThrustVsDrag #FlightControl #HowAirplanesFly #AerospaceEngineering #Aviation #FlightLanding #AircraftControl #FlightDescent #LandingGear #WindEffects #FlightSafety #AerodynamicForces
