To ensure its aircraft is production ready by 2028, the company uses #amazonwebservices High Performance Computing (AWS HPC) services. Learn how AWS helped PLANA compress 8 years of work into 3, complete design simulations in hours instead of days, and lower HPC simulation costs by 70%. @Andre Kearns @Sandeep Sovani @Tim Murnin #aws #aerospace

A post (read it in link [1] which is posted under the first comment) that popped up on my feed about aircraft landing (particularly those from Airbus) with flare mode. The flare mode is described on the AOPA website as: ["The gradual pitch-up just prior to touchdown - slows the descent and allows the airplane to settle gently on the runway: • Flare too high or too fast, and the aircraft drops abruptly • Flare too low or not enough, and the aircraft lands hard or flat"] Aircraft approaching and landing on the runway remain the most critical flight phases. It accounted for ~50% of fatal accidents and 75% of non-fatal hull losses between 1997 and 2016. The design, tuning & validation process of final approach and flare control systems remains a challenging task. I was curious to look up the topic, so I checked the MathWorks site, if there's a demo available on flare control, but none. There is a Simscape landing gear control demo on MathWorks site (see link [2]), but that's different from flare control. So, I thought to search on Google Scholar, as there must be a/some published paper/s available on aircraft landing approach with flare control and then voila! There are a number of them available. I've only read one of them. See link [3] in the comments, which is relevant to Aircraft/Aerospace Control Engineers. • "Robust Autoland Design by Multi-Model ℋ∞ Synthesis with a Focus on the Flare Phase" The authors used #Matlab and #Simulink with the Robust Control Toolbox (RST) to develop a flare control model called "Autoland" for aircraft landing under strong wind conditions and parametric uncertainties. The objective of their study was to control the vertical speed of the aircraft before touchdown while minimizing the impact of wind-shear, ground effects, and airspeed variations. Autoland uses H-Infinity controller rather than the traditional LQR (linear quadratic regulator) used in aircraft designs of today. H-Infinity is more robust than LQR, but it added complexity to the design. Aircraft automatic landing in the vertical plane can be divided into two main phases: • the final approach during which the aircraft must follow a descent path (glide) • the flare segment, which is activated when the landing gear height falls below a threshold value which is most often fixed ≈50 ft but might be slightly updated as a function of ground speed. Similarly, in the horizontal plane, the aircraft trajectory must coincide with the runway axis (localizer phase) as long as landing gear height is ≈30 ft. The alignment phase (or decrab mode) is then activated in order to minimize the lateral efforts on the landing gears at touchdown. The following Airbus short video clip shows how the pilots land an A320 aircraft. There's a user-story on MathWorks site (in link [4]) on how Airbus Engineers used Matlab & Simulink to design the fuel management control system of the A380 aircraft: • "Airbus Develops Fuel Management System for the A380 Using Model-Based Design"

OneWeb and SpaceX’s LEO User Terminals Limitations  OneWeb and SpaceX have designed and are in the prototype phase of their LEO User Terminals.  While OneWeb relies on Mechanically Steered Antenna Array, SpaceX utilizes Phased Antenna Array technology.  In order to connect to first LEO satellite and handover to the second incoming LEO satellite, there is a tight time constraint, which Mechanically Steered Antenna Array solution requires two antennas. These antennas are typically dish antennas with high profile. This high profile limits these LEO UTs to Fixed Wireless Access, FWA, applications and market. The Phased Array Antennas however are suitable for fast switching speed via single antenna array and can connect to LEO satellite 1 and handover to satellite 2, dynamically in order of ~100 us time, which are feasible for LEO requirements. However, Phased Array Antennas are expensive and typically used for military applications and cannot be streamed line for commercial applications. There is a greater opportunity for Mobile LEO UT which neither of the above solutions address form technical and cost perspective. There is market for flat antenna array design in Ku and Ka bands. Flat Antenna Array is not only attractive for commercial applications but also addresses mobile LEO UT, such as Autonomous Automotive.  It is view of ORTENGA that cost effective Flat Antenna Array can be realized to address mobile market whether it is LEO or 3GPP Release 17 networks. Augment ORTENGA with your design and development teams to address growing Autonomous Automotive markets. ORTENGA OneWeb Technologies SpaceX Kymeta Corporation UC San Diego

Prem Andrade, Distinguished Engineer at Ansys, explores the digital engineering journey for an eVTOL, from mission planning and concept selection to design and operation. He explains that the eVTOL digital engineering journey begins with mission planning, concept selection, and safety. The next step is to decide which concept has the best system configuration and performs most effectively, efficiently, and safely by conducting a trade study on possible configurations. An important component in this assessment is the system architecture model. #DigitalTransformaton #eVTOL
