June 2009 - Silent 2 Wins Region 5 East Contest, Jefferson , South Carolina , USA
|
A Silent 2 sailplane flown by Sarah Kelly claimed Sports Class first place at the Region 5 East
contest hosted by Bermuda high Soaring www.glider.org in Jefferson , South Carolina .
The Silent 2 pure sailplane flown by Sarah meets the difficult FAI Class-DU limit of 220 kg (485 lb)
max takeoff weight.
Accordingly, the published handicap set for the 300 kg ( 661 lb ) Silent 2 motorglider was officially
adjusted for the 220 kg DU glider to correct for its lighter wing loading.
Sarah flew the glider well, taking advantage of the glider's better climb rate to overcome its
reduction in best-glide speed and upwind penetration.
In her words, "The contest experience with such a light, easy to rig, and familiar sailplane was
superb, and I thoroughly enjoyed each day."
See the SSA Contest Reports www.ssa.org/members/contestreports/ContestResultsDetail.asp?id=352 page for additional
information.

April 2009 - Silent 2 TARGA Jet-Powered
|
|
|
|
AliSport's attendance at this year's AERO was a huge success.
The biggest crowd pleaser was the debut
presentation of the jet-powered variant of the 13.3
meter Silent 2 Targa.
The single-engine jet powerplant is still a
pre-production prototype and performance data will
be released only once the flight test program is in an
advanced stage.
A decision to enter series production has yet to be determined.
The installation details differ from that of the
sucessful and concept-defining 12.0 meter Silent
twin-jet flown by Bob Carlton on the airshow circuit

March 2009 - Ballistic Recovery System available for the Alisport Silent 2 TARGA
|
All models of the Silent are now available with an optional ballistic recovery parachute system
integrated into the fuselage structure.
The system, in development for three years, uses a pyrotechnic rocket and a Junkers Magnum 300
parachute with a 66 m2 (710 sq. ft.) round canopy.
The system can be used at speeds up to the Vne of 220 km/h (137 mph) and full canopy inflation
occurs within 80 m. (262 ft) of altitude loss.
The Alisport "total rescue system" is housed in a structural compartment located in the lower
portion of the fuselage just aft of the wings. The compartment, identical for unpowered and
powered variants of the Silent, is positioned so that it allows room for the standard self-launch
engine and pylon installation.
In-motion ground firing tests (see the photo sequence below) were performed to obtain
certification from the DAeC in Germany for the Silent with an installed ballistic recovery system.
The pyrotechnic rocket exits the right side of the fuselage immediately aft of the flaperon.
Once fired, the recovery parachute takes 5 to 6 seconds to stabilize and orient itself vertically
above the sailplane.
The lines of the side-firing system transition to the vertical by means of a steel cable segment of
the parachute bridle tearing through a sacrificial portion of the fuselage skin.
The parachute bridle straps are tethered to the wing spars to guarantee the most contiguous
attachment to the airframe.
The complete system weighs approximately 9.5 kg (21 lbs). According to European regulations
pertaining to sport aircraft, the maximum takeoff weight (MTOW) for aircraft equipped with
recovery systems can be increased from 300 kg (661 lbs) up to 322.5 kg (710 lbs).

June 2008 - Motorized "Sport & Recreation" Sailplane Gathering, Spessa Po', Pavia, Italy
|
A special gathering of gliders occurred from June 20 th to the 22 nd 2008 at the Speziana airstrip near Pavia in northern Italy . The combined event included both modern light sailplanes and vintage gliders. The first-of-its-kind event drew about fifteen pilots and their motorized aircraft; sailplanes capable of autonomous taxiing and self-launching. The attendees came from all parts of Italy and for many this was the first opportunity to meet and visit with fellow self-launch sailplane owners, as guests of the Corbellini family at their beautiful airstrip.
|
|
|
|
|
Gliders in attendance included variants of the 12-meter Silent Club, including an electric
self-launcher, Silent 2's, Silent 2 Targa's, Tauruses, and a Swift, all capable of self-launching and
retracting their engines into the fuselage. Vintage gliders included a Schleicher Ka-6, Morelli M-100,
and a beautiful Libelle H301, towed aloft courtesy of tug pilots Tessitore and Borgo with their
vintage Stinson L5, and Pietra with a gorgeous Piper PA-18 and a YUMA.
The event was a complete success with much gliding activity thanks to the three days of summer
sun and heat on the tail end of two weeks of continuous rain; the cultivated fields were still
waterlogged and the Po' a very swollen river. Numerous friends with airplanes and motorgliders
also flew in to visit the Speziana airstrip during the event. A warm “arriverderci” until next year's
gathering of light sailplanes.

February 2008 - Motorized Silent 2 Certified in Swiss "Ecolight" Category |
| |
| In another significant airworthiness step, following last year's German certification of the self-launching Silent 2 on April 17th, the Silent 2 obtained certification in the Swiss motorized "Ecolight" category on January 31st 2008. The Silent 2 is also the very first glider to be granted certification by the Swiss Confederation. The new "Ecolight" qualification allows the Silent to be legally flown within the borders of the Swiss Confederation (ULM flights were previously not permitted) and opens the doors for anxiously waiting Swiss pilots to obtain Silent gliders. The first Swiss Silent 2 will be delivered in March of 2008.

February 2008 - SSA Convention, Albuquerque, New Mexico, USA
|
Alisport was present at the 2008 SSA Convention with the new self-launch Silent 2 TARGA and Bob Carlton's Twin Jet Silent.
The event, running from Thursday February 14th through Saturday February 16th, was held at the
Albuquerque Convention Center
in the beautiful southwestern state of New Mexico. The two exhibit halls were sold out of floor space and the forty-plus presentations well-attended.
Bob Carlton of Silent Wings Airshows
presented on the current state of jet propulsion in gliders around the world and Alisport's US representative, Leo Benetti-Longhini, provided an update during the
Auxillary-Powered Sailplane Association (ASA) breakfast on manufacturing developments at the factory.
Interest in the various models of the "class-defining" Silent was exceptionally high.

September 28 th 2007 - Silent 2 TARGA Kit Completion and Maiden
Flight,
Virginia, USA
|
Mike Hostage of Norfolk, Virginia successfully
flew the maiden flight of his kit-built Silent 2 TARGA pure sailplane
on September 16th 2007 after receiving his airworthiness certificate
on the 8th of September. He wisely progressed through ground roll
and ground effect auto tows before transitioning to the first aero
tow. The first two flights were uneventful and each lasted over
an hour to fully explore the handling characteristics and performance
envelope of his sailplane
(N-195MH). Mr. Hostage concluded that his sailplane was spot-on
and needed no tuning adjustments.
Mike's sailplane was built per the kit manual's instructions and
design drawings, but with some builder deviations for the instrument
panel and the tow hook.He painted the sailplane with two-part polyurethane
from Loehle Aero Coatings. Mike informs us that the empty weight
and balance was right in the center of the allowable range and the
empty weight was 147 kg (324 lbs) – very comparable to factory
gliders having similar options and features (retract gear, hinged
canopy, etc).
Mr. Hostage talks positively about the quality of his Silent quick-build
kit. He is an experienced builder who previously built a Marske
flying wing from plans. In the short term, Mike plans to continue
flying his Silent 2 TARGA as a non-motorized sailplane and hopes
to explore electric self-launch options at a later date. Congratulations
from all of us at the factory! |

August 2007
- First Canadian Silent 2 TARGA takes Flight, Quebec, Canada |
Silent 2 TARGA s/n 2027, C-GODY, recently
took to the clear Canadian skies after one month of ocean voyage
and within three weeks of delivery – time needed to complete
paperwork formalities. The pure sailplane (registered C-GODY) is
based at the Bromont Airport in the province of Quebec - about 86
km (53 miles) east of Montreal, Quebec and 82 miles (132 km) north
of Burlington, Vermont. The glider is the first Silent imported
into Canada and therefore has a Special Certificate of Airworthiness
in the limited classification for non Canadian type-certified gliders.
This particular Silent has the standard TARGA vertical-style winglets
and ingenious variable-incidence stabilizer interconnected with
the flaperons. It currently has a fixed landing gear and will be
retrofitted with a retractable mainwheel plus a self-launch powerplant
as soon as the pending regulatory approvals are received from the
Canadian authorities. |
|
| |
| The sailplane has been test flown by several
experienced Canadian CFI pilots and all are impressed with its light
weight, ease of rigging, predictable flight characteristics, balanced
handling, banked slow-flight behavior, ability to climb in weak thermals,
effective airbrakes, and short-field landing capabilities. Above all,
the pilots are enamored with the innovative variable-incidence stabilizer:
specifically the absence of conventional spring trim with its artificial
stick pressures, the elimination of elevator trim drag, and most importantly
the pitch-control redundancy provided by a separate control system
connected to the flaperons. A video clip of a trial flight by CFI
Pierre Moreau, including post-flight commentary, is available for
download from YouTube.

April 22nd,
2007 - 500km Distance to Goal, Florida, USA |
Leo Benetti-Longhini informs us that at the conclusion
of Sun 'n Fun at Lakeland and the Wills Wing Demo Days at Wallaby
Ranch he was able to fly a 500km declared distance in a Silent 2 glider.
The northbound flight, from Wallaby in Florida to Montezuma Airport
in Georgia, was performed in an FAI Class DU non-motorized Silent
2 glider (under 220kg T/O weight).
Leo reports that there was a challenging 15kt crosswind for first
half of flight, followed by heavy smoke with almost IFR visibility
across south Georgia from the Okefenokee swamp fires, then blue sky
past Tifton. He terminated the 6.5 hour flight at the declared goal
due to battery problems, instead of proceeding for a free distance
attempt. The flight has since been approved for two Florida state
records - one in the DU class and one in the Sports class.
|

Leo wishes to thank ground crew and Sun 'n Fun volunteers, Daniel
Schur and John Dotson, who followed the entire way and arrived
within minutes at Montezuma, Georgia.

Avalon, Victoria, Australia |
Bob Carlton of Silent Wings Airshows performed
five day-shows and one night-show at the 2007 Australian International
Exposition and Airshow.
The multi-day event at Avalon, about 40 miles from Melbourne, included
the three-day "Australian International Aerospace & Defense
Exposition" followed by the weekend-long "Australian
International Airshow". More than 200,000 spectators were in
attendance on Saturday.
The jet Silent received rave reviews, including approval from non-other
than Chuck Yeager, a guest of honor at the event. Mr. Carlton commented
very favorably about the organizers, sponsors, and enthusiastic
attendees.

November 2006
- Variable Incidence Horizontal Stabilizer
|
| The sailplane
is trimmed in pitch via an innovative variable-position horizontal
stabilizer. The stabilizer position is governed by the flaperon
setting: the five settings of the flap control produce corresponding
changes to the stabilizer incidence, thus defining the trim airspeed
in relation to the flap requirements. The conventional elevator
remains in trail, minimizing trim drag.

March 2006 -
FAI Gliding Commission IGC Meetings, Lausanne, Switzerland |
A proposal of interest to Silent owners was accepted
at the March 3-5th meeting of the IGC in Lausanne, Switzerland.
Agenda item 12.3.3.g, originating from the French Gliding Federation
(FFVV), calls for a new FAI class of motorized gliders under 300kg
(660lbs) and 450kg (990lbs), max take-off weight (TOW) for single-seaters
and two-seaters respectively, and a stall speed of 65km/h (35kts)
or less.
The proposal lists several reasons (lower costs,
reduced bureaucracy, no medical requirements, etc) as reasons for
the emergence of many light self-launchers meeting these weight
and stall speeds. The weight and stall values given match the requirements
for light aircraft in most European countries (most often described
with general names such as microlights, ULM’s, ultralights,
sport and recreation aircraft, etc, depending on the country in
question).
The proposal goes on to state that, even though
there is always a risk of having too many classes of gliders, it
would be a missed opportunity if the IGC does not recognize the
importance of establishing a class to accommodate this thriving
segment of aviation. Whether such a new class would be a variant
of the existing DU class (non-powered with max TOW of 220kg) or
a totally new class is not yet known. The proposal is open for comments
for one year. If adopted, the benefits to owners of self-launch
Silents cannot be overlooked. |

July 2005 - Another World Record for the Silent
2
Zapata, Texas, USA |
Gary
Osoba significantly raised the bar in the FAI’s DU-Class record
rankings by flying approximately 604 miles (972 km) on Monday July
18th in a Silent 2 pure sailplane. The free-distance flight put Osoba
within a mere arm’s length of surpassing 1000 kilometers, the
“Holy Grail” of the DU glider class and a hurdle not unlike
the first 1000km achieved with a Sisu back in the 1960’s. Gary
reports that conditions at Zapata were strangely lacking the early
morning cloud-streeting that the Texas border town is known for. He
went on to say that there was some organization of cloud streets once
on the plateau north of Uvalde and his speed was good until conditions
deteriorated about halfway into the flight. He expects that analysis
of his flight trace will show average lift in the 300-400 fpm (1.5
to 2.0 m/s) range. Gary ultimately made it well into the Texas “panhandle”
and landed safely at a ranch near Amarillo, Texas.
It is also worth reporting that, after towing
half the pilots at the WRE, Bo Hagewood went on to set a new single-surface
hang-glider world record of approximately 190 miles (305 km) in a
borrowed Falcon. Another participant, Robin Hamilton, also set a new
distance record of about 425 miles (684 km) in a Swift. So we have
a truly amazing “Record Monday” with three new records
in gliders of vastly different performance, ranging from a Falcon
to a Swift to a Silent! From all of us at AliSport, congratulations
Gary, Bo, and Robin. May you all have additional successful flights
in the next few weeks.
|
|
|
| Osoba comments very favorably on the handling
and performance of the Silent 2 and plans to make more distance and/or
speed attempts in the near future. After Zapata, the Silent 2 will
likely be flown at Big Spring, Texas while the 2005 US National Hang
Gliding Championships are held there. With exception to some large
scale weather phenomena, conditions in Texas have been considerably
drier this year than in 2004. Osoba’s exhausting 10-hour 40-minute
flight was barely squeezed into a challenging weather window between
the remnants of Hurricane Dennis and fast approaching Hurricane Emily.

Report for additional reporting by Davis Straub or David
Glover’s excellent WRE

April 2005 - New DU
Record Flight, Georgia, USA |
David Stevenson
of Atlanta, Georgia, USA flew over 900km (560 miles) on Sunday April
24th, 2005 in a Silent 2 pure sailplane. He launched at 9:10 AM from
Jasper, Marion Co. airport in Tennessee where he was towed by John
Bloomfield of Chilhowee Gliderport to his release point in the northwest
corner of his home state of Georgia. After some tricky saves in the
weak, early morning lift he was able to connect with the Sequatchie
ridge and proceeded to his first turnpoint at the northern edge of
the Sequatchie Valley near Interstate-40. Next, he headed south into
Alabama to his second turnpoint at Collinsville (halfway between Fort
Payne and Gadsen), then north again to his third turnpoint back in
the Sequatchie near Dunlap, Tennessee.
Stevenson then headed southeast aiming for Charleston, South Carolina
and the Atlantic coast! After several more difficult saves crossing
a wet drainage area of the Tennessee River he finally reached higher
and drier terrain in the southern Appalachians. From there the conditions
improved as he continued toward his goal. The next challenges came
first with a low of 400m (1400 feet) AGL near Athens, Georgia followed
almost immediately by a flight computer shut down caused by a faulty
electrical connection. Fortunately the logger continued to record
the flight while David switched to his back-up sectional charts. Nine
and one half hours after the start he landed at Hampton, South Carolina.
He was assisted in his venture by fellow pilot and ground crew, Murray
Forbes of Atlanta. |
|
|
| Preliminary statistics
are 95 km/h (59 mph) average cross-country speed, 28% thermalling
time with average 1.9 m/s (370 ft/min) climb, 49.7 L/D, and 61 glides
with 136 km/h (85 mph) average glide speed. His data file is available
for download on the website of the AeroKurier OLC. Stevenson plans
to submit his flight to the NAA and FAI for record approval as a declared
3-turnpoint distance in the DU category. His RECORD
complements other records set with the Silent 2 and brings the elusive
1000km DU hurdle even closer to reality. Congratulations, David on
your amazing achievement. |
