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.

To guarantee maximum safety and reliability, our DA 30 features a brushless motor and a contactless wear-free position sensor. This means maximum service life with the greatest‐possible power delivery and its design prevents electromagnetic emissions (EMI) caused by brush sparking. The housing made of saltwater‐resistant aluminum is HART‐coat treated, meets the IP‐67 standard for water and dust sealing and provides an integrated Sub‐D connector (MIL spec. circular connector or cable gland on request). Brackets integrated in the housing for horizontal and vertical assembly. 8‐fold, ball‐bearing supported, steel gear train, drive shaft with ANSI multi‐tooth. The DA 30 series can be equipped with a standard PWM input (Pulse Width Modulation) that has two different interfaces: a differential, galvanic isolated interface (Opto‐Coupler) and a single‐ended interface with CMOS levels that is also used to program the servo parameters. It includes analog position feedback to detect the drive shaft position. A differential RS‐422 PWM interface can be chosen instead of the opto‐coupled interface. The DA 30 with digital serial command interface (RS‐485) receives its commands via a CRC secured protocol. It can return not only the shaft position in digital format, but also several diagnostic data such as the level of the supply voltage, current consumption and the temperature of the motor and electronics in digital form (optionally also the humidity within the actuator case). These kind of diagnostic capabilities help to determine the health state of the actuators before, during and after deployment.

Supports non-destructive inspection of aircraft composite skin structures and is composed of a piezoelectric layer sensor, data acquisition equipment, and damage analysis software. Utilizes piezoelectric sensors to generate Lamb-wave and acquire signals, collecting data to accurately detect and assess composite damage. Visualizes inspection results on display such as damage location, size and index. - POD Accuracy: 1 inch 90% or more - POD Precision : Position error within 30 mm - 64 channels / 230 path reference detection time within 10 minutes - Sensor : Resonance resistance less than 400kΩ - Sensor : MIL-STD-810G - Sensor : RTCA DO-160 Section 23.0 - DAQ : x128 Piezoelectric sensor interface

SURI-III is a super multi functioning sight, optimizing firing capabilities for Caliber 50(M2) and AGL(MK19)in the day and night time condition. It could be supported by HMD for User’s shooting position in convenience and for saving Force’s lives. Thermal Camera + Day Camera + LRF + Red Dot Sight + Wireless Goggle + Customized Reticle + Wide Screen presents in One Device

Liquid Measurement Systems (LMS) provides fuel gauging and interface controls for service, maintenance, and flight crew personnel, at the primary refuel point on the aircraft.

External Refuel Preselect Panels can display the quantity of fuel in each tank, calculate the total quantity of fuel onboard, allow service teams to pre-select desired fuel quantity, and display fault codes. LMS’ external refuel preselect panels are compact, lightweight, and rugged systems that can be adapted to a variety of platforms.

- To measure RCS for the aircrafts, warships, helicopters, chaff and etc. - Verify to meet pre-defined RCS specifications on design phase.

The specifications for vessel design, manufacture and inspection comply with the ASME standard of the USA, as well as the standard of the Korea Gas Safety Corporation. These vessels are manufactured and exported to countries all over the world.
