Since the late 70s, designers
have tried to make semi-rigid hang gliders with varying degrees
of success. Many projects ended prematurely with test pilots
being killed or injured.
Than the arrival of the Bright Star Swift in late 1992 rekindled
the fire for real foot launchable sailplane/hang glider. In
my mind, the Swift was too impractical and heavy and failed
to hit the mark; if you are going to go that far then a sailplane
would be a better option, and on top of all the hassle you lose
that all important feeling of the wind on your face.
The Exxtacy and Pegasus were
born in 1997 and now two years on with the E-7, Ghostbuster
and Atos, a new generation of exciting foot launch wings is
beginning to emerge. The weight of these new wings has already
dropped dramatically and this is just the beginning of their
development.
Maybe Im a dreamer, but in a few years time perhaps
well be flying a weightshift 20:1 glider which weighs
less than 25 kilos
SETTING
UP
Carrying a rigid wing is one hell of a job if you have got
no buddies around to help you out. The carbon fibre D spar
leading edges are about 50 cm wide when packed, so perching
them on your shoulder and hiking to take-off is no mean feat.
The designers have sewn handles at either end of bag, so even
they obviously expect their customers to have a helping hand.
Assembling the wing was quite straightforward, and only because
we followed the instructions did it take longer than normal.
I would imagine that with a little practice you could have
an ATOS assembled in less than ten minutes. The process is
much the same as with a regular hang glider only you dont
have to bother stuffing battens because the ribs are permanently
attached to the beautifully worked carbon fiber D spar leading
edge.
The airframe is up to the usual
high standard that we have come to expect, and there are some
nicely machined alloy parts connecting the leading edges.
The carbon fiber work is exquisite and every piece I examined
was, as far as I could see, perfect. The sail is relatively
simple and has required very little shaping which helps keep
the sail almost wrinkle-free. As usual the shark rod tops
are a bitch to get on. Its only just a one man job if
you are Superman; I just managed it. Theres only one
thing that is vital to remember and that is to connect the
spoilers.
LAUNCHING
The wing has a good static balanceon your shoulders, just
a little tail heavy which I prefer. The main difference from
a hang glider is the short root chord which you notice most
when you are preparing for take off. The nose of the wing
is only just in your field of vision unlike a hang glider,
which almost reaches the horizon in comparison.
I was told to set the flaps to 15 degrees for take off and
thermalling.
Holding the wing ready for
launch, I did notice that the wing slops around a little.
This is due to the lack of side wires. Never the less it was
easy to ground handle in the light winds and later I found
that in strong winds it becomes even easier. Stood on the
ramp at Kennedy launch (Gourdon, France) I rotated the nose
down and accelerated as hard as possible. After three steps
I was off, thinking to myself how easily it came unstuck and
how little effort would be required to do the job well.
FIRST IMPRESSIONS
The first thing I do when I test a wing is to hold the base
bar very lightly between thumb and forefingers, then I just
let the wing find its natural balance point. From this reference
point I started to explore the potential of the Atos.
The sky was a little overcast
and the conditions were far from ideal, with very weak lift
drifting through from time to time. The first ten minutes
were a little fraught as I discovered the wing could be over-controlled,
considering that my last hang gliding flight was over a year
ago.
At first I was trying to fly it like a class 1 hang glider,
which made my thermalling erratic and not very efficient.
I was applying too much pitch and roll command, but once I
had toned it down a little the wing began to transform into
a pleasant and efficient machine. As I climbed out above launch
a flexwing hang glider that had taken off after me began to
sink out as the Atos seemed to waft ever higher.
HANDLING
I was seduced by a smooth co-ordinated feeling the Atos offered
when centered in the lift. There was so much less work to
do; no pushing, pulling, yawing and highsiding as is necessary
with a class 1 machine. After twenty minutes in the air I
was already thinking that I might just need a wing like this.
The sky beginning to brighten up, so I set off on glide with
no particular goal other than to enjoy myself.
One last turn then I flicked off the flaps for the first time
and pointed at my next destination. On releasing the flaps
the wing surged forward and I cruised off at 65 km/h with
no effort.I know the area of Gourdon well as it is home to
most of my paragliding test work, and as I neared the village
itself I realized just how much better this wing is compared
to anything Id ever flown before. The village of Gourdon
is an old medieval fort perched on a spine, and on a Sunday
afternoon it is full of tourists soaking up the sun and the
impressive views. I arrived below the village and climbed
in a small thermal, imagining myself as a huge Himalayan Vulture,
my wing gracefully lifting me into the view of the tourists.
As I climbed skyward I watched my shadow slice over the tables
and umbrellas and marvelled at the Atoss sleek shape.
Time had come to head for a
rocky ridge to see how it handles when scratching close in
to the hill. Flaps on and I snuggled in tight, monitoring
the wing tip closely as I contoured the relief. It was here
that I found out that the Atos was a little slow to respond
compared to a flexwing hang glider, so I moved away slightly
and felt lots more comfortable. With the extra performance
and sink rate it would appear to be of no disadvantage to
have a little more clearance from the ridge, in the same way
that you dont find sailplanes scratching on ridges with
their tip only a metre off the deck. I hit a good thermal
and as the swordlike wing rose I cranked it hard into the
core and climbed with a steep angle of bank. So smooth and
co-ordinated
I had very little work to do so I enjoyed
the view of my home village as I rose ever higher.
The wind was from the east
so I set off into the headwind towards the lee side of the
Courmettes, a 5000 ft mountain that dominates the region.
Time for some turbulence! I encountered the first of it as
I approached the mountain, some snotty curl-over. The wing
just continued on its path effortlessly, and with a totally
rigid sail and airframe, I was not thrown off course even
in the thick of it. There was a good strong rough lee side
thermal so I jabbed the A-frame across and into it. The ride
was great, and the Atos seems to really enjoy strong lift,
climbing like a paraglider but feeling like a sailplane. As
I pressed on into wind in a mix of thermal and turbulence
I took time out to watch the wing for movement, but there
wasnt even the slightest futter from the sail as I approached
a top speed of 85 km/h in rough stuff. I slowly returned the
bar to trim and the wing rose constantly for much longer than
I expected. The bar pressure at full speed was very positive
and I felt safe and confident that it would not just tuck
at any moment.
If I was to fly it on a regular basis then I would prefer
a little less pressure because it feels like you would spend
a lot of time flying fast with this baby.
I was wishing that it was mine
so that I could really go and explore its potential, but instead
I settled for cruising past the paragliding take off to show
my buddies the toy I had borrowed for the day. No way I would
swap for one of those, I thought to myself as we flew into
the distance.
I wanted more still so I thought
a little landing practice would be good. On approach to a
top landing, I pulled full flap on as instructed, and my airspeed
dropped and my descent rate went through the roof. I pulled
in because speed is your friend when you are low, and with
the flaps on it felt too slow for a wing like this. The glider
plummeted but the notorious turbulence attempted in vain to
throw me off course. Slowly I bled the speed off and was surprised
to find myself still airborne at an unfeasibly slow speed.I
pushed hard as I thought Id cocked it up, but I was
wrong. The wing responded by stalling and placing me on my
feet: easy. Manhandling the wing in turbulence was a doddle.I
squared it into wind, gave a few steps and enjoyed another
easy take-off. I liked it so much that I top landed once more,
then I unclipped, took a few paces back, put my ass on a rock
and admired its aesthetic beauty. It really is a nice wing
to look at, and the high aspect ratio emphises the feeling
of performance which oozes out of this machine. I took to
the skies again with ease, reinforcing how user friendly it
was. The last word from Gianni was that it was mine to fly
on Sunday, so after my three hour flight I decided to go and
land in the official field. My landing was not perfect as
yet again I was fooled by the slow speed at which it would
still fly, so I pushed to hard , too early and my flight came
to an abrupt ending. The wing was immediately surrounded with
hands fingering its most intimate parts of the wing. I learnt
that all these pilots had come from miles around to test fly
the Atos as well on this day. Apparently they had been cursing
me for not coming down as the afternoon went by. I must apologise
to those pilots if I had been told of their plans I would
have landed much sooner (well, may be).
CONCLUSION
The last hang glider I flew was a Gugenmos RCS. I was impressed
and enjoyed my flight. This however was something different.
I was left with a big grin on my face, and the desire to have
one of my own.
Everything that I have ever wanted out of flying is now available.
The speed and glide open a new dimension of possibilities
and the ease of take off and landing mean you can fly knowing
that at the end of the day you wont need a 200 metre
long airstrip to get down safely. Combine that with the easy
handling and I think you could fly a huge distance on one
of these babies. But I think most club flyers will be drawn
to this wing for its feeling alone. The only negative points
I could find are that it is a little fragile in the flap area
and the difficulty you have when carrying the thing alone
when packed.
The Atos is truly a refined product.
