We are one of the world's leading manufacturers of both military and commercial aircraft ground support equipment. Hydraulics International, Inc. is proud to be one of a few small companies having the total self sufficiency in the design and fabrication of aerospace ground support equipment.

The R10s is a reconnaissance and surveillance drone capable of conducting up to two hours of mission flight, transmitting real-time information such as target location and scale to the ground control system. Based on the company’s innovative vertical take-off and landing (VTOL) platform “Bluebird,” the R10s is equipped with EO/IR optical sensors and a laser range finder for advanced target detection. Upon receiving mission orders, the R10s takes off vertically, transitions to fixed-wing flight, and proceeds to the designated area. Its onboard cameras and sensors identify and track targets, relaying precise coordinates to the ground control system. With modular wing replacement, the R10s can be configured for extended endurance of around two hours or for high-speed maneuverability, ensuring optimal adaptability and mission effectiveness across diverse operational scenarios.

Our XR-based aircraft maintenance simulator is officially certified by the Ministry of Land, Infrastructure and Transport (MOLIT) of South Korea for training and education. It provides specialized training environments for the A321, B737-MAX, and B737-800NG aircraft, featuring over 80 detailed modules—including procedures for engine removal, main landing gear installation, and more. This subscription-based simulator is fully compatible with smartphones, tablets, and wearable XR devices, enabling seamless access through a cloud-based web service. Users can train anytime, anywhere—perfect for both remote learning and remote maintenance scenarios. Compared to traditional classroom learning, the XR platform is 4 times more effective and requires only one-third the training time. It also improves user confidence in real-world technical applications by up to 275%. By transforming traditional paper manuals into immersive, interactive training environments, the simulator delivers the next generation of aircraft MRO education for both civil and defense sectors.

Lumir is the first Korean company to successfully develop and manufacture this onboard equipment, delivering superior performance and significant cost savings compared to competitors’ products. By integrating non-volatile NAND flash devices into the image data handling unit, storage capacity has been significantly increased, with data retention maintained even when the power is off.The image data handling unit of the satellite is a core device that receives high-speed, large-capacity data output from Earth observation sensors mounted on the satellite—such as SAR or optical cameras—then compresses and stores the data in real time, while also performing encryption and encoding for transmission to ground stations. Lumir has successfully developed and manufactured this satellite-mounted device domestically in Korea for the first time, breaking reliance on imported technologies. This achievement secures Lumir’s competitiveness by delivering superior performance and significant cost savings compared to foreign products.

It is a product lineup that is proven in global markets and has world-class competitiveness. And it is being exported to more than 20 countries around the world.

The RFcore Radar series are FMCW type radar and were developed to detect/track small air targets. The major difference between three models is detection performance. RX32B is fundamental model. RX128B have four times larger radar than RX32B. RX192A have six times larger radar then RX32B. The number of the product name means the number of antenna elements. All have compact and lightweight physical architecture that concentrates all the components required for radar, such as antenna, RF components and radar signal processor, in a small single housing. Transport can be carried in the carrier box and can be easily carried by one person. For installation, you can use a commercially available camera tripod. The weight is about 7.5kg (RX32B) and 15.9kg (RX128B), and the lower connection part is compatible with the tripod connection for the camera. Power supply requires 12VDC (RX32B) and 24VDC power (RX128B and RX192A). When using a battery, it is possible to connect a 12V battery or 24V battery to radars. Usage time may vary depending on the battery capacity. RFCORE recommended the constant power supply. Transfer of Status and BIT information and simple control of the RX32B, RX128B and RX192A are possible with a web browser using the Ethernet connection for authorized users. Using the terminal program provided with the radar, you can view the radar control and detected target information in real time. All RX Radar series’ Power Amp and Core Chip were designed using RFcore's own products.

The MIL-DTL-5015 series of connectors were developed as military standard connectors and applied to various military equipment, it is also used in general industries, medical care, electric vehicles, robots and automation facilities based on its high durability and reliability. This series is threaded coupling and the connection between the contact and the wire is based on soldering. It can be used compatibly with third-party products of the same standard since it is produced according to military standards.
