MODULAR-TUB is a partner project at TU Berlin as part of the joint research project MODULAR (Smart Actuator Concepts for electromechanical und electro-hydraulic Drives). MODULAR aims to develop innovative concepts for smart electromechanical and electro-hydraulic actuators. It is funded by the Federal Ministry for Economic Affairs and Energy (BMWi) as part of its Federal Aviation Research Programme (LUFO VI-1). The planned project duration is 39 months (01.01.2020 – 31.03.2023). The joint research project is led by Liebherr-Aerospace Lindenberg GmbH.
The project MODULAR-TUB at TU Berlin contributes towards model-based software development of digital intelligent flight control systems and the development of new approaches for dissimilar control-monitor functions that are typically used in fail-safe safety-critical systems.
Flight control systems of modern commercial aircraft mainly use hydraulic actuators. Recent advances in power electronics make electric alternatives viable. Electromechanical actuators (EMAs) are already used in the secondary flight control system. The use in the primary flight control system is especially demanding in regards to reliability and service life of the actuators. Those systems are safety-critical and are therefore covered by strict development, certification and quality assurance processes.
The joint research project MODULAR aims to develop innovative concepts for smart electromechanical and electro-hydraulic actuators. Research topics include more efficient methods for system design, new approaches in system monitoring and constructive solutions and control principles for electromechanical and electro-hydraulic actuators.
TU Berlin’s partner project MODULAR-TUB contributes by developing new monitoring mechanisms for next-generation flight control systems and work on efficient, model-based development processes of flight control software towards goal 4 (system capability) of the Federal Aviation Research Programme, as an understanding of the interaction of individual sub-systems (actuators, sensors, on-board computers) and the overall system “aircraft” are required. Mechanisms for the detection of Common Mode Failures contribute towards goal 2 (safe and passenger-friendly aviation).
The scientific and technical goals are:
The joint research project consists of four main work packages (HAP):
|EHA & Test Environment
|Innovative technologies for electro-hydrostatic actuators and test environment
|FCS Rotary EMA
|Intelligent digital Flight control system using load controlled electromechanical actuators
|Highly integrated EMP
|Highly integrated hydraulic electric motor pump with intelligent system monitoring
|Highly integrated and standardised electric drives
MODULAR-TUB is part of HAP2.
The Department for Flight Mechanics, Flight Control and Aeroelasticity is responsible for the tasks of TU Berlin. The tasks are part of three work packages (AP) and comprise the following topics:
Project Duration: 01/2020 – 03/2023
