The JS1 Revelation. 18m/21m flapped sailplane
Piston Glider Jonker Sailplanes
Description
The JS1 Revelation, high-performance FAI 18/21-metre Open Class sailplane.
The JS1, designed with incorporated aspects such as aerodynamics, structures, and pilot comfort, has rapidly gained world recognition with its great performance and handling characteristics.
The JS1 is available as either a pure sailplane or with the MD-TJ 42 jet sustainer system installed. Although production has been discontinued, immaculate previously owned JS1’s are available across the globe.
UNMATCHED
PERFORMANCE
The JS1 not only displays good gliding ratio at moderate speeds but also at high speeds and maintains its outstanding climbing performance.
A lightweight structure and a unique double-hole blowing/suction system on the wing enabling very low drag allow the JS1 to reach a top speed of 290km/h. Another gain for speed is water tanks in the wings, a small lift sacrifice for a big advantage.
With the combination of excellent performance, a wide range of available wing loadings and superlative handling, the JS1C-21m is extremely competitive at the highest level, without the disadvantages of older generation Open Class gliders.
The increased wing loading, combined with new tip aerofoils and third-generation winglets gives the JS1 its edge at high speeds.
