The Neoptera eOpter is being developed in a joint venture in Bristol, UK, and Toulouse, France. The eOpter is an electric VTOL that uses eight propellers for thrust generation.
Stage of Development
Neoptera has not built a full-scale version of its eOptera yet - the largest sub-scale test model has the following dimensions:
Wingspan: 1.2 m (4 ft)
Weight: 10 kg (22 lb)
The company is currently seeking funding so it can produce the full-scale version of the aircraft.
From the Neoptera website:
Neoptera Ltd has been developing since 2017 a unique winged Vertical Take-Off and Landing (VTOL) civil light aircraft capable of transporting 2 to 5 passengers (or equivalent payload).
Winged VTOL aircraft offer the versatility of helicopters (enabling vertical take-off from compact helipads) combined with the energy efficiency of aircraft (benefiting from the lift afforded by fixed wings to extend range).
Thanks to our aerospace experience and our understanding of the challenges involved in the design, development and certification of aircraft systems, we have concentrated our efforts on safety and simplicity whilst at the same time offering a truly novel concept.
Thinking outside the box, we believe that we have managed to come up with a proposition that will offer a unique passenger experience that may well become the benchmark for future transition VTOL.
Our aircraft relies on distributed electric propulsion to offer a fault tolerant solution with mutliple levels of redundancy. Our aircraft is ready for the next generation in battery technology but the modularity of our concept is also compatible with a range of electric energy sources such as hybrid power unit or fuel cells.
Our Take on Neoptera
Neoptera has several funtional sub-scale eVTOL models to its credit, however none of them are larger than 5 feet in wingspan. If the company can secure the funding, watch there next scale models closely, as their performance will indicate future success for the team.
