At 6:06:38am, Asfaloth lifted to the skies of Xuhai for the first time. This mission was aimed at shaking down a completely new rocket system and its launch tower, as well as the maiden flight of the Tsua-Ing 1300kgf-class hybrid rocket engine. The team for Launch-1 is brought together by the students and faculties of ASARe Lab, ARRC and MSCL, NYCU's Mechanical Engineering Department and iSSE, along with program collaborators 國家太空中心 TASA, Autodesk Education TW, 宇宙喵 Kuroro 地球總部, 益材科技. _________ Video shared by TASA and photography team.

• What are event-based (EB) cameras? • Ans: High kHz-rate imaging in the form factor of a chicken nugget. Traditional high-speed cameras operate by capturing sequences of images at rates ranging from hundreds to thousands of frames per second (fps). Each image comprises a rectangular array of pixels conveying RGB or gray values corresponding to incident light. The memory-intensive nature of high-speed recording typically entails: 1. A trade-off between image resolution and fps. 2. Restricted capture duration, often limited to burst-mode only. 3. Significant camera footprint, weight, power and cost. In contrast, EB cameras contain pixels that independently trigger in response to changes in incident light. The retained information encompasses pixel-position, time of trigger, and a binary value indicating the direction of light intensity change. The reduced data size allows EB cameras to achieve equivalent high kHz-rate recording within a highly miniaturized and lightweight device. Our research centers on exploring and leveraging the potential of EB cameras for hypersonic vehicles, where weight and volume are at a premium, and where dynamics are on the order of 10-kHz: • “AsyncELF”: Development of Event-Based 3D Imaging for Hypersonic FSI Measurements https://arc.aiaa.org/doi/10.2514/6.2024-2492 • Analysis of Event-Based Camera's Potential for In-Flight Measurement on Hypersonic Test Vehicles https://arc.aiaa.org/doi/10.2514/6.2024-2659

🚀 Elevating Hypersonic Diagnostics with Event-Based Imager 🚀 In contemporary times when hypersonic vehicles, quiet supersonic jets, and reusable rockets take center stage, furthering the science of high-speed aero-, thermo-, and structural dynamics is paramount. For transonic aircraft, aerostructural dynamics may occur at around 100's of cycles per second (Hz), while hypersonic vehicles push the envelope with frequencies reaching 10,000's Hz. Measuring these dynamics traditionally involves a trade-off between spatial and temporal resolution, alongside device footprint. E.g. a high-definition kHz-rate camera may be impractical for free-flying test aircraft. "Event-based (EB) camera," a nascent machine vision technology, may redefine the diagnostics trade-off. Based on pixels that respond independently and asynchronously to external stimuli, EB cameras offer high-kilohertz-rate response in miniature packages, ideal for integration into drones or embedding in high-speed test vehicles and wind tunnels. ASARe Lab collaborates with Professor Currao et al. to explore the use of EB cameras in measuring fluid-structure interactions in NCKU's transonic wind tunnels. ------ Research by: ASARe Lab: Prof. Z.
