The Rolladen Schneider LS8 is a single-seat glider of the standard class with originally 15 m wingspan , winglets and a rigid wing profile.
The LS8 was created by fixing the flaps of the wing of the LS6 . After the concept had proven to be successful, the wing shapes were created with an adapted wing-flap transition. The fuselage was adjusted in the area of the wing transition, as the angle of incidence had to be increased due to the rigid profile.
Versions are the LS8, LS8-a, LS8-b, LS8-e neo, LS8-t, LS8-s, LS8-18 and the LS8-sc neo. The wingspan can be increased to 18 m using clip-on wings, making the aircraft part of the 18 m class.
The LS8-b has a modified fuselage structure with an engine box in preparation for engine installation. The wing structure was reinforced in the area of the spar. A total rescue system was no longer installed behind the cockpit due to the insolvency of the Rolladen Schneider company.
The LS8-t has a homecoming aid . It was planned to increase the total weight of the aircraft to 575 kg, which was later implemented by the new owner of the molds. Until 2003 the manufacturer was Rolladen Schneider Flugzeugbau , later DG Flugzeugbau in Bruchsal , where the further developed versions LS8-s and LS8-st (with turbo drive) are manufactured.
Since the beginning of 2017, the aircraft has been available as the LS8-sc neo with a 5-inch main landing gear, a small tail wheel with a diameter of 150 mm, Mandl suction and neo winglets. The cockpit was replaced by that of the LS10 . The aircraft type was equipped with a turbo preparation as standard in order to be able to be equipped with a homecoming aid at a later date. The successor LS8-e neo is based on a similar concept with an electric drive, the Front Electric Sustainer System (FES), with an output of 22 kW. The electric drive is fed by two lithium polymer batteries with a capacity of 40 Ah (4.2 kWh) each and an integrated BMS . Optionally, the propeller and batteries can be dismantled and supplemented with a simple molded part, which means that the conversion corresponds to a non-powered LS8-sc neo.
Use and flight characteristics
Comfortable flight characteristics, good rudder adjustment and gliding performance make the LS8 a successful competition aircraft that can be flown in the standard class as well as in the 18-meter class (with clip-on wings). The LS8 is also used in advanced training because of its good-natured flight characteristics.
