PTO SHAFT, Proven Performance, Realized in Reality CTLA's Power Transmission Shaft (PTO-shaft) is a key component of the aircraft secondary powertrain, transmitting the high-speed rotational power generated by the aircraft engine drive unit (EMAD) to the gearbox (AMAD). By applying high-strength, lightweight titanium material for the first time in the world, we have achieved both weight reduction and durability, while implementing outstanding stability and reliability through our proprietary electron beam welding technology optimized for high-speed rotation and high-speed precision balancing technology. In particular, this product, which is currently being mass-produced and delivered to the KF-21 fighter jet, has demonstrated excellent power transmission performance while minimizing vibration even in extreme environments. CTLA is leading technological innovation in the field of high-speed rotational machinery, spearheading the self-reliance of domestic aircraft components and advancing into the global market.

ZYX SPACE is an intelligent design platform that integrates artificial intelligence into the architectural design process. It is designed to minimize repetitive tasks through automation and empower designers to focus on creativity and decision-making. With its advanced AI engine trained on over 80,000 architectural drawings, ZYX SPACE can automatically recognize 2D floor plans, identify key elements such as walls, doors, and windows, and generate accurate 3D models in real time. Designers can experience seamless 2D-to-3D transformation without the need for manual modeling. ZYX SPACE also offers powerful daylight analysis features, simulating natural sunlight movement to visualize indoor lighting conditions and energy efficiency through heatmaps. This enables informed design decisions that consider both aesthetics and sustainability. One of the platform’s standout capabilities is converting image-based drawings into CAD-compatible vector files. ZYX SPACE not only extracts geometric data but also recognizes numerical information embedded in scanned or photographed blueprints, making legacy data usable in modern design workflows. Through auto-learning and labeling features, the platform continuously improves its recognition accuracy by learning from accumulated project data. It automatically classifies architectural components and spatial configurations, boosting productivity and reducing errors. ZYX SPACE also supports AI-driven interior rendering. It analyzes room layouts to suggest optimal furniture placements and delivers real-time visualizations based on different interior concepts, helping designers and clients envision the final space with clarity. When combined with ZYXCAD, ZYX SPACE provides a highly integrated design environment—enabling end-to-end automation from drafting to visualization. This powerful synergy allows architects, engineers, and designers to accelerate their workflows, improve precision, and unlock new levels of creativity.

The Sentry Mesh 6161 is a Software Defined Radio hosting our highly robust MANET waveforms that have been proven in applications from Public Safety to Unmanned Systems and Covert Operations. The MeshUltraTM waveform optimises the use of available channel bandwidth through a token passing technology, which avoids collisions and provides a bound, predictable data packet latency. Wider bandwidth, together with superior RF performance and optional Interference Avoidance System (IAS), maximises communications effectiveness in the presence of interference. The standardised design of the 6161 ensures that it can be integrated with a large range of accessory devices such as audio, data, power solutions, and antennas to address current and future program needs.

It is equipped with advanced multi-sensor payloads such as EO/IR and LiDAR, enabling precise data collection in diverse environments. The drone is optimized for tasks ranging from infrastructure inspection to tactical surveillance. Its versatility allows operators to adapt quickly to different mission requirements with a single platform.
