T/FA-50 PTO Shaft, The New Standard for Next-Generation High-Speed Rotating Power Transmission The power transmission shaft (PTO Shaft) applied to the T/FA-50 features in-house designed, optimized flexible couplings that provide excellent durability. In addition, the adoption of high-speed precision balancing technology effectively suppresses vibration and ensures shaft oscillation prevention. While it shares a similar form with the KF-21 power transmission shaft, the T/FA-50 PTO Shaft incorporates unique, dedicated technology, making it distinct. The system development has been completed, and performance improvements are continuously underway with the goal of localization.

Relief Valve ensures high flow rate compared to competitor market designs. Climb/Dive Valve is a pressure equalizing solution for enclosed volumes that experience pressure differential levels between the internal and external pressure values of the system. Ball Valve is very commonly used on UAV and land systems. It is available with high torque and low torque actuation. Materials, sizes, end connects customizable.

Due to its lightweight nature, TYTO 100 can transmit photos/low-resolution video from Manned and Unmanned Platforms beyond line of sight. TYTO 100 features an all-in-one Certus SFX module and antenna, with power supply. Wi-Fi and Ethernet Connectivity can be easily paired with existing customer devices, and Global Satellite Connectivity can be added. The TYTO 100 can also be used as Standalone mode with built-in Battery.

We developed and optimized an object detection and tracking solution tailored for edge environments using Intel Atom platforms with OpenVINO. The system combines MobileNetV3-SSDLite for detection and MobileNetV3-Small for tracking, enabling efficient real-time performance on resource-constrained devices. Through model optimization and inference acceleration, we achieved over 2x improvement in FPS and more than 50% enhancement in inference speed, all while maintaining detection and tracking accuracy. This demonstrates the solution’s suitability for lightweight, low-power edge AI applications

Between Earth and space: stratosphere-compatible, solar-powered high-altitude aircraft, known as HAPs (High Altitude Platforms), offer a sustainable alternative to satellites for Earth observation and communication. They are reusable, cost-effective and flexible in use. The DLR joint project HAP-alpha is developing such a technology demonstrator and is endeavoring to establish a complete system capable of permanent operation. The aim is for DLR to build up comprehensive expertise for the development of high-performance, high-flying solar aircraft and to play an active role in shaping the legal framework. In summer 2025, the HAP-alpha successfully passed a ground vibration test.
