A major development focus in aerospace is the ”More Electric Aircraft (MEA)“. Liebherr offers therefore mature and field proven solutions with its broad product range in power electronics. Motor-control electronics for electrical 4-quadrant drive systems with different power ranges support a wide range of applications, such as electrical actuation or electrically powered compressors for air conditioning. In the near future, Liebherr product portfolio will be enhanced by power electronics in ATA 24, such as Transformer Rectifier Units (TRU's). Many different drive and power electronics applications by Liebherr have accumulated in-service experience in recent aircraft programs. At the exhibition stand Liebherr presents among others its motor control electronics, the Rudder Motor Control Electronics (MCE) for Airbus - A400M, as well as centralized control and monitoring of the high lift system (flap/ slat), the Flap/ Slat Control Unit (FSCU) for Embraer - E-Jets G2.
Liebherr control electronics are based on powerful micro-controllers. For safety-relevant applications, these units are designed with a control/ monitor architecture and the form factors are configured according to the customer’s requirements. Today, Liebherr control electronics can be found in the fields of flight control systems and landing gear actuation as well as in air-conditioning, cabin pressure control and deicing. The high degree of hardware standardization allows a broad range of use in new applications. The Liebherr exhibits in this area are, for example, the Remote Electronic Unit (REU) for the performance of actuator control and monitor functions independent of a flight control computer, as well as the Landing Gear Actuation & Steering Control Unit (LGSCU) for Bombardier - C-Series for the retraction/ extraction of the landing gear and nose wheel steering.
Due to the longtime experience in the development and production of own electronic modules, the Liebherr Components division is also a competent partner for EMS. The highly-qualified staff and modern technical equipment at Liebherr ensure the professional and high-quality product manufacturing. Besides built-to-order manufacturing, Liebherr offers EMS in several forms, ranging from development to after-sales service. On these grounds, Liebherr is able to respond excellently to customer requirements.
