The Kortenbach & Rauh Kora 1 was an unusual twin-boom, pusher motor glider, designed and built in Germany in the 1970s and intended as a training aircraft.

Recognition (WEFT)

WEFT is AircraftIQ's four-point recognition method — how it works.

Spot it by:

• central pod fuselage with the pusher engine behind the cockpit
• two slender tapering tail booms running back from the wing, each ending in a fin
• tailplane carried on top of the fins and projecting outwards

A cantilever high wing with a constant-chord centre section and tapered outer panels, with Schempp-Hirth airbrakes opening over the inner wing. The cockpit is 1,200 mm wide under a starboard-side opening canopy.

Specifications

• The Kortenbach & Rauh Kora 1 has a length of 7.4 m (24 ft).
• It has a wingspan of 18 m (59 ft).
• Its maximum speed is 205 km/h (127 mph).
• Typical crew: 2.

History

It was a two-seat side-by-side motor glider built entirely of wood by Kortenbach & Rauh, who were best known as furniture makers. It had a 64 hp Limbach SL 1700EC1 air-cooled flat-four engine behind the seats.

Variants

Two prototypes were built. The first, which flew on 13 September 1973, had a fully retracting tricycle undercarriage, while the second, which flew in 1976, had fixed spatted mainwheels, which increased the glide angle from 31.4 to 30.

Where you'll see it

The second prototype was still undergoing flight tests early in 1978, with no production decision reached despite orders for some twelve aircraft. It remained on the German civil aircraft register in 2010.
