As
former helicopter pilot, and historian
of vertical flight I had the opportunity to study the
problem of the vertical mobility very close, experiencing directly
through hours of flight, allowing me to have a clear analysis
of technical issues related to these type of aircraft.

aerodynamics)
CellCraft
projects in brief is an aircraft that could maintain the same
property of the extraordinary helicopters, but
combined with the typical speed of fixed-wing aircraft,
and most important maintain a very high levels of security and
flexibility as well. That means that a such type of machine should
be capable to land and take off vertically, as
well flying at high “appreciable” speed.
Since
the beginning I started with the constant idea of designing an
aircraft that summed up in the concept more or less of both helicopters
and airplanes be capable of the same performance and I called
this machine: CELL-CRAFT ©
or "G".
The
CELL-CRAFT©
today isn’t the sole project of this kind, as well as many
other it is an alternative aviation idea, it rather represents
a concentration of research in various fields of a futuristic
scenario next too come. It is a type of aircrafts developed on
different platforms. The concept of horizontal-vertical flight
in few words means: new environment and architecture of
the cockpit, and a new way of interaction between
man and machine, that makes this project pretty much
different from the classic idea of an aircraft as we know it today.
The CellCraft came
out while developing both the style and the architectural structure
of a modular flying system.
The term CellCraft
came out since it indicate the architecture of the aircraft itself,
the structure remind that of a typical modular system. The aircraft
also looks very compact, designed according with the idea of keeping
together individual elements technologically autonomous, identified
as main modules but assembled into a single harmonious system;
in other words been a unique and integrated structure, having
a main brain, a cell called AFC (Automatic Flight Control)
discussed ahead in details.
There
are several types of Gs (CellCraft) and many
different versions for any appropriate roles. My attempt over
here is to make a description of the most representative projects
in a the most easy way, leaving the reader having a clear view
of the entire matter. This site will also be updated with the
latest design variations or versions of the related projects,
finally a historical section shows the whole evolution
process that took the long way over the course of the years since
1996.
Architecture
of the Aircraft: G450-455
In
2003, contemporary with the development of the
project G440, almost
completed, I decided to revise the original concept once again,
starting from the first project, making a review of that machine
originally designed in 1996: the G150.
It was now the time since I could get the right technology to
re-build it as a brand new aircraft, which until then I could
only dreamed. In 2003, in fact, the technology
related to induction-electric-motors with digital
control for traction had begun its course and development providing
a growing production of electric motors ever more efficient and
reliable, perfectly adaptable to an aircraft which would fly with
full electric propulsion; and that was exactly what was originally
planned for the G150
project.
The following projects opened the second phase of the design process,
and new projects were already describing the future CellCraft’s
idea getting
the right shape. All Those projects were provided with a serial
hybrid system, in other words the transmission was connected
to both a turbo-shaft turbine engine, as well
to an electric motor inserted inside the transmission
disc (G412-13-16-18-20).
The transmission system was basically a very compact mechanism
intended to distribute the power to the various axial compressors
or multi-stage ducted-rotors.
Projects were very diversified among them and in some cases the
electric motor was inserted inside the axis of the ducted-rotor
(G440; G500). Furthermore
these machines had the rotors lying on the horizontal axis and
equipped with deflectors of various types designed to
re-direct the air-stream thrust in
a given direction. This was a feature of its own, technically
conceived for the second project’s phase: the G412
(1996) up to the G440 (2003).
The
G150’s project or a possible variation
of the most recent (G450-455),
was now perfectly feasible and more advanced than the original
design exercise, and after all quite contemporary. I like to think
about the future to something we alredy have but we should be
patient while waiting for, whatever it is it will eventually become
real soon or later.
