Integration: Engine Control Unit
In addition to the structural components, the operational reliability of the entire powertrain must be demonstrated. For this, a battery testing program and a ground testing program have been established. More systems will be tested in stages during the test, before the full flight test program is finally flown. For example, the successful completion of ground testing enabled the first exit and entry tests at the idaflieg summer camp. The individual components are listed below, along with the associated verification and required testing.
In a scientific work the control unit, (Engine Control Unit (ECU) or EAGLE Control Unit), was developed. Under the name EAGLE, the Rosenheim University of Applied Sciences, together with the RWTH, is preparing the further development and testing of the software for the cockpit instrument for integration into the aircraft and for flight certification. The cockpit instrument is being prepared for integration into the aircraft and flight certification. The system state machine controls the start-up and shutdown of the propulsion system. Compliance with MISRA-C:2012 development guidelines was also required for all developed source code. Algorithms for estimating the charge and "state of health" of the propulsion system's lithium battery were also evaluated in the process
The Engine Control Unit is the so-called EAGLE Control Unit of the EAGLE project of the FH Rosenheim under the direction of Prof. Dr.-Ing. Birger Mysliwetz.
This consists of a 36x48mm color LC display in the center, two blocking toggle switches in the upper right corner, and a rotary knob with a push button in the lower right corner. The upper toggle switch is called the Up/Down switch, it specifies with its position in which state the system should currently transition. If it is up, the system will start to extend the motor, if it is down, the system will start to retract the motor. The rotary knob is used to navigate in the software and to select the speed, the push button function is used to confirm inputs and messages. The middle toggle switch is reserved for later use and is currently not wired. The display shows the status data of motor and battery. This includes the speed (RPM), voltage as well as temperature values. This gives the pilot the correct overview of the system status.
Do you have questions about the project or would you like to join us? Then just write us anemail or meet us at the weekly meeting. It doesn't matter which subject you are studying or which semester you are in. We are always looking for motivated team members who are committed to take part in our project independently. With us, you will get exclusive insights into aircraft development and can gain experience in aviation alongside your studies. We are looking forward to you!
For about a year now, the FVA is cooperating with the Institute of structural mechanis and lightweight construction (SLA) at RWTH Aachen University.
Back in January, we conducted a first test run of the load experiment with an early model of the pole.
