Our latest project, the FVA 30, is dedicated to solving the electrification of aviation, just like FVA 29. With the accumulated experience and the brilliant solutions from our predecessor projects, we would like to make a big step now: we want to build an airplane, which is designed only to be electricity powered during the whole flight, from the beginning to the end. Our first mission to be completed is:

 

Travelling from Aachen to Berlin faster and more efficient than driving.

Why electric aircrafts?

 
The advantage of the electric flights is clearly evident. It takes an aircraft far less time to reach the destination, independent from the traffic situation. It leaves more environmentally friendly CO2 footprint. It is also easy to operate, letting you enjoy your time sitting in a quiet aircraft while overlooking the landscape beneath you.
Therefore, it makes sense that leading aircraft manufacturers should be actively involved in the field of electric flights. Commercial flights with hybrid aircrafts will be offered in 2030. Our goal is to offer some thought-provoking ideas and make our dream come true.
However, electric aircrafts also have their disadvantages. The main problem is the power supply, which is supported by batteries in many prototypes. The amount of energy in advanced batteries today is not yet enough to carry several people for such a long distance. The development of a hybrid concept is therefore worthwhile. Electricity should not only be supplied from a battery, but also form a separated generator driven by conventional fuels.
We want to explore the feasibility of a methane-powered hybrid aircraft, which, together with the generally high efficiency of a motor glider, is as environmentally friendly as no concept before.

Conception

 
As a student group, we should develop a concept that optimally exploits the advantages of the electro-hybrid flight. As a result, it only makes sense to use the efficiency of a motor glider and to modify an existing model.
A modular concept is useful to us because we can quickly present complex solutions in several phases without having to go through the workload. In project work, several concepts with different engine positions and aircraft shapes were examined. A V-tail plane configuration was found to be the most efficient and simple solution. In addition, we want to ensure a quiet flight, so the design of the propellers was also researched.

There is still a lot of theoretical work to be done before the construction work can begin. Electricity and motor layout, propellers, aerodynamics, structure and power supply should be further developed. To this end, simulation, calculation and interpretation are simulated. Nevertheless, we are satisfied with our work so far and are still reporting on latest results.
Rage: 650 km
With the route from our home flying station, Aachen-Merzbrück, to Berlin Schönefeld (530 km) and a buffer of 120 km, we are able to cope with any unforeseen situation such as detours or delays
Travel speed: 150-200km/h
At this speed, our aircraft would be most efficient, so it can achieve the lowest fuel consumption and still reach the destination in a proper time.
Travel cost: < 100€
Along with methane cost and the depreciation of engine, batteries and aircraft. This would make the chartering of an electric aircraft very affordable and could be used, for example, during training. Of course, the aircraft would also be extremely attractive for normal travel.
Seats: 2
A pilot and a passenger sit side by side.
Travel height: max. 3000 m
Under 3000 m, we do not need any additional oxygen. This is quite good, because oxygen is essential if you want to stay alive.
Takeoff distance: < 500 m
So that we can take off from our home airfield Aachen-Merzbrück.
Noise: < 60 dB-A
If you are 200 m away from our aircraft, it would only be as loud as a car in the urban area.
