In the end of May the Flugwissenschaftliche Vereinigung Aachen (1920) e.V. will finally celebrate its 100th anniversary.
100 Jahrfeier (100th anniversary celebration)
Basic Sailplane Maintenance course
After most of the participants had arrived a day or two beforehand, the course finally started on Tuesday, November 15th.
Project thesis on the design of an engine mount for the FVA 30
What is the most clever way to combine the progress of one’s own studies with the FVA while still advancing a project as sustainably as possible?
AERO Friedrichshafen Video
At Aero 2022 in Friedrichshafen, Germany, we exhibited part of the FVA30 powertrain test bed. What it’s all about and what important role the Speedgoat Real Time Target machine is playing, FVA 30 project manager Paul explains in the following video.
e-Genius Besuch
After some members of the FVA already visited the Institute of Aircraft Design (IFB) in Stuttgart in 2019 to check out their electric powered glider e-Genius, which is the prototype of our FVA 30, it was time for another visit last week.
Certification Process for a Hybrid Electric Aircraft
The scientific aviation association (FVA) is developing the FVA 30, a hybrid electric motor glider, in order to research alternative propulsion systems. Due to strict safety requirements in aviation…
Battery Management System Integration into an Electronic Control Module for a Hybrid Electric Aircraft
During development of the powertrain, engineers face the challenge of designing an electronic control module (ECM) for reliable data processing, so that pilots can monitor and control the drivetrain. In electric aircraft…
Wing Prototype building
After a long time, a more complicated piece of fibre-reinforced plastic construction was once again produced in the FVA workshop.
CFD Workshop
CFD can be a critical tool in the design processes as a proper analysis can improve the efficiency of the entire construction.
Tail Wheel Construction and Control
Due to the landing gear arrangement of the FVA 30, a tail wheel is required.
Propeller-Tail Interaction
After the complete sizing and design of the V-tail of the FVA-30, an important effect affecting the tail was studied again in more detail during the last semester: The interaction of the propeller wake with the flowed-around control surfaces on the empennage and the resulting rudder effectiveness significantly influences the verification of longitudinal and lateral stability both in twin-engine operation and in single-engine operation (one-engine inoperative, one-sided propulsion failure) and thus also affects the design of the empennage.
Flight Performance Computer Revision
The overall propulsion design depends significantly on the performance requirements resulting from the planned flight profile.
Wing Load Comparison with the e-Genius II
In the last article, a first load comparison between the wings of FVA-30 and e-Genius was carried out.
Control Unit & HMI
The system architecture of the FVA-30 is a continuous evolution driven by the requirements of the various components of the aircraft. Important for the design is not only the electrical powertrain, but also mechanical assemblies such as the trim, avionics and lighting of the aircraft.
Engine Tests: Approval Regulations and Test Design
To prepare the engine runs for the EMRAX 228 HV used, we followed the certification regulations of JAR 22 (Section H Subsection Test Bench Runs) and then made a proposal to the LBA (German FAA) for our approach to the engine runs.
