GENERAL AVIATION

 EXCLUSIVE: Y6S Plus unveiled
 UK urban air mobility start-up Autonomous Flight has revealed a new, highly modified version
 of its Y6S eVTOL – the Y6S Plus. The Y6S Plus retains the Y-configuration of three pairs of
 rotors of the previous design but ditches the ducted fans of the forward pair. It is also larger
 and sized for six people, rather than two. The company is still in the investment phase and
 is tight-lipped about further details and project timescales, but has exclusively shared these
 renders (including the front cover) of the Y6S Plus with AEROSPACE.

                                                                 Single pilot

                                                                 to allow six passengers to be carried.

Multi-role eVTOL
The Y6S Plus is being designed from the
outset to be adaptable through its structure
to other roles, apart from point-to-point air
taxi services, such as a cargo drone and air
ambulance.

Although of smaller vehicle size, this year’s
competition has synergy with our GA Design
Competition and so the team from the Islamic
University of Technology (IUT), which won three of
the six prizes in the IMechE competition this year,
was invited to take part in our design conference.
Tausiful Islam, a student at IUT, is the Team Leader
and Chief Operating Officer of ANTS Aerial
Systems and he presented their impressive project.

The Freedom Drone
Tausiful detailed the need for a rapid response
system to deliver urgent small package medical
aid anywhere in Bangladesh. The Freedom 71
drone system has been developed to do just that,                                                  The UK to see the light again?

RAeS International General Aviation Design
Competition 2020
The RAeS design competitions are aimed at promoting major innovation in the general aviation aircraft sector and past
winners have triggered several exciting projects. The results for the 2020 competition were announced at this year’s
General Aviation Design Conference. The competition was again run in conjunction with the Light Aircraft Association.
Its mission was to define a vertical take-off, battery-electric aircraft able to evacuate the injured from a storm swept island
in the Caribbean. The scenario was the island of Dominica which was devastated in 2017 by Hurricane Maria.
The mission was to fly a stretcher case, attendant and pilot to another island. The aim was to achieve maximum range
with reserves. This had to be backed up by a comprehensive design report and flown in a simulator. Most powertrain
parameters were defined at 2020 levels.
This was the toughest design competition yet but has led to some excellent designs. Once again, winners came from
around the world.

                                                                          The A2CAL team from Berkeley US won first place with

The competition has been organised thus far around the calendar year. However, there is pressure to change to fit in with
the academic year in future, with the competition announced around May, in time for supervisors to fit a project within
their curriculum. So the next competition will be announced in May 2021 but not closed until after the end of the summer
term in 2022.
Readers are invited to submit ideas for the next competition which must be targeted at innovation in GA aircraft. Send
ideas to knowledge@aerosociety.com.

A new challenge
ISRO’s unpiloted missions will test the launcher,
crew module and other associated technologies
destined for human spaceflight. In January 2020,
the space agency unveiled a half-humanoid robot
that would be part of both unmanned space
missions. Named ‘Vyommitra’ – Sanskrit for ‘space
friend’, the half humanoid will be capable of
speaking two languages, performing environment
control and life support systems (ECLSS) functions,
operating switches aboard the spacecraft and
recognising voice commands.

to launch vehicles and spacecraft management
with access to extensive infrastructure in terms
of launch pads, ground tracking stations. It also
