Cover eFlight Presentation Story Forum<br />
Guo Yilin from the Liaoning General Aviation Academy<br />
(LGAA) and Tengluan Sui from the Stuttgart aviation<br />
company Kasaero are not only working together on<br />
the approval of the latest version of the RX1E. They also<br />
presented their work together at the e-flight forum China.<br />
The RX1E-A variant differs from the first version from<br />
2014 in many details: The most important are the range<br />
of 240 kilometers and a flight time of 2 hours. The latest<br />
progress is a new battery with 50 kWh instead of the previous<br />
40 kWh, which gives the plane 30 minutes more<br />
flight time. The German approval is sought in order to<br />
gain a foothold throughout Europe. In addition to the UL<br />
approval for Germany, Liaoning is also working in other<br />
directions in the further development of the project. A<br />
version with floats was presented last year. Liaoning is<br />
convinced that the quiet plane without noise and exhaust<br />
fumes is ideal for use on rivers and lakes, where it neither<br />
disturbs tourists nor pollutes the environment.<br />
and the approval at the CAAC has been running since<br />
November 2019. The RX4 should have a flight time of<br />
1.5 hours with a range of 300 km and a take-off weight<br />
of 1200 kg.<br />
Since the LGAA is a spin-off from Shenyang Aeronautic<br />
University and has been working with fuel-powered<br />
drones there since 2011, it was obvious to develop a hydrogen<br />
drive for manned aircraft as well. The fuel cell of<br />
the hybrid four-seater is to be installed behind the passengers<br />
in the cargo compartment. The machine should<br />
be ready for series production and available on the market<br />
in five years. The Kasaero company - around company<br />
founder Karl Käser - has received three type approvals<br />
in the last four years. Together with the manufacturer<br />
from China, it was decided to first aim for UL approval<br />
for the DULV, because this can be achieved more quickly<br />
and is significantly cheaper than an EASA approval.<br />
A four-seater based on the RX1E was also completed,<br />
which is to be approved according to Part 23 and is considered<br />
a Chinese prestige object. The development<br />
started in 2018, the first flight took place in autumn 2019<br />
In addition, the RX1E-A is also intended as an entry-level<br />
machine for flight clubs. And price naturally plays a decisive<br />
role here. In addition, with UL approval - in contrast<br />
to EASA CS-LSA approval - neither DOA nor POA<br />
