anthony brown has been called upon by many companies to bring his expetise and knowledge to their aid...he beleives the integrity will not only fly,handle well,but most importantly...be certifiable...attached is another example of what he has done..
The dangers of turbulence
behind en route commercial
aircraft could be better
understood and thereby
limited, following new
research by Canada’s
National Research Council
Institute for Aerospace
Research (NRC Aerospace).
NRC Aerospace (Hall 4,
C17a) has installed and
tested new instrumentation
on its Canadair CT-133
aircraft that will enable it to
gather extremely detailed
information on the effects
of turbulence generated by
commercial aircraft.
Aircraft travelling
through wake vortices can
experience substantial aerodynamic
loading and flight
path upsets, possibly
causing injuries to passengers
and structural overload.
Armed with its new air
data acquisition system,
which can collect 600
samples of inertial and air
data a second, the CT-133
performed six calibration
Light relief from
Rockwell Collins
Rockwell Collins (Hall 4,
Stand F10) is showcasing
its CISS-2100
Configurable Integrated
Surveillance System,
which combines weather
detection, traffic alert
and collision avoidance,
Mode S surveillance and
terrain awareness and
warning functions into
a single system.
It also features
Rockwell Collins’
MultiScan Hazard
Detection System, which
provides fully automatic
weather hazard detection
up to 320nm,
ground clutter suppression,
and enhanced
turbulence detection
capabilities.
The CISS-2100 uses
40% fewer parts than
traditional aircraft
surveillance systems,
reducing the weight,
volume and power
consumption.
Eaton’s low-cost
fluid sensor
A new oil indicator
sensor that determines
oil fluid levels in intermediate,
tail rotor and
main gearboxes has been
developed by Eaton
Aerospace (Hall 4, F12).
The retrofit item
works with existing
aircraft wiring interfaced
with a remote
indicator at the
cockpit caution panel
to detect the presence
of oil.
This also eliminates
additional wiring and
space requirements and
minimises upgrade
costs.
Thales upgrades
Merlin sonar
Thales UK (Hall 3, C5)
has been awarded a £27
million contract by
Lockheed Martin to
upgrade the acoustics
(sonar) system of the
Merlin multi-mission
helicopter.
The award covers the
upgrade of 30 helicopter
systems with options for
eight further systems in
the future.
The upgrade, together
with a Sonobuoy
command and receiver
system, will give the
aircraft enhanced
performance, especially in
shallow water environments.
The upgrades will be
undertaken by Thales
UK’s underwater systems
Anti Submarine Warfare
(ASW) Airborne group in
Stockport, England, and
supported by airborne
group elements in Brest,
France.
Canadian research logs wake vortex data
flights in May, followed by
a wake vortex flight behind
three commercial aircraft –
an Airbus A310, A319 and
Boeing 767-300.
Later this summer, NRC
Aerospace will refine the
instrumentation and undertake
further data gathering
flights.
The study follows one
conducted by NRC
Aerospace in 2004, using a
Dassault Falcon 20 and less
sophisticated instrumentation.
Anthony Brown, NRC
Aerospace research officer
and test pilot, says: “We
gathered data at 600Hz,
which is 600 samples per
second. To our knowledge,
this is the first atmospheric
research aircraft to do so at
that high a rate. It gave us
an immediate impression of
the wake vortex flow field
that we just didn’t observe
when we gathered data at
32Hz using the Falcon. As a
result, we feel that this is a
good platform to obtain
detailed information on
wake vortex flow fields.
“Our goal is to obtain data
on the flow phenomena to
clarify the risk and highlight
the desirability or the need
to develop wake vortex
turbulence warning instrumentation
that can be
installed on aircraft.”
