Silent Club

 

The Silent Club is a light sailplane with 12-meter fiberglass wings for recreational flying. It has a blend of agility, control responsiveness, climb performance, safety, and fun. The two-position flaps have a reflex position to maintain good glide performance at higher airspeeds. The pure sailplane and fuel-injected self-launcher versions were available as quick-build kits. Assembly is simple, both due to all controls having fully automatic connections and due to the light weight of the wings. The airframe is built entirely of composite materials, with use of carbon fiber in the aft portions of the fuselage pod, the tail boom, and various critical locations of the structure. The cockpit is completely built of glass fibre. The Silent Club's low sink rate and its stability while thermalling allow it to fly with hang-gliders and to be practically unbeatable in climb when compared with Standard class or 15m class sailplanes. It is easy to both launch and to land, and is particularly suitable for new pilots performing their first single-seat flights. The Silent Club has very efficient conventional air brakes and can be landed in less than 70 m (230 ft). Due to its span of only 12 m (39 ft) it can be stored in a small space. A fully enclosed "clam-shell" trailer is available for road transportation.


The Silent 2 is a high-performance light sailplane with 13-meter wings for recreational and sport flying.


The carbon-fiber wings have an elliptical planform, removable winglets, and five flap settings to cover the entire speed range. The pure sailplane and fuel-injected self-launcher versions were available as quick-build kits. Several World records have been set with the Silent 2 in the FAI Class-DU. A basic airframe combined with reasonable pilot weight will generally result in a take-off weight under the 220kg (485 lbs) maximum allowable required for the FAI's DU Class. The Silent 2's airframe is built entirely of composite materials, with use of carbon fiber in the aft portions of the fuselage pod, the tail boom, and various critical locations of the structure. The oven-cured wing structure includes extensive use of carbon-fiber. The sandwich skins use vacuum-bagged carbon fabric for the interior layer and glass fabric for the exterior layer while the wing spar uses pultruded carbon rods for the spar caps. It tows well behind trikes, sport-aircraft, and regular towplanes, making it versatile for all types of glider operations.


The Silent 2 TARGA is a high-performance light sailplane for recreational and sport flying. It has retractable landing gear, vertical-design winglets, and horizontal stabilizer with automatic trim. The pure sailplane and fuel-injected self-launcher versions were available as quick-build kits.

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 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 +40 for thermalling, to 00, -40, 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.
