The class-leading Silent 2 TARGA is a
high-performance light self-launching sailplane for recreational
and sport flying, powered by the proven “Alisport A302efi”
engine producing 28hp at 6200rpm. This single-lever FADEC
engine has electronic ignition, fuel-injection, electric start,
and flywheel generator. The patented counterweighted monoblade
carbon-fiber propeller has a swept diameter of 1.4m and electrically
retracts into the fuselage along with the engine pylon.
The wings have an elliptical planform, vertical
design winglets, and a span of 13.3 meters. The wing structure
includes extensive use of carbon fiber, both in the sandwich
skins and in the tapered
I-beam wing spar which uses pultruded carbon rods for the
spar caps. The wing geometry is unique in that it varies non-linearly
from the root to the tip, both in overall planform shape and
in wing section profile. The flaperons stretch for 11.0 meters
of the full wingspan and their range of motion varies from
positive landing L, to +4° for thermalling, to 0°,
-4°, and S reflex positions for cruising.
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.
The ingenious trim system,
the elliptical planform geometry of the tailplane, the vertical
design winglets, and the retractable landing gear all combine
to yield improved performance over a wide range of airspeeds.
