Condor 4

 

The Condor was designed by Heini Dittmar with the advice and help of Atexander Lippisch and Dipl-lng Fritz Kramer; the Condor owed something to an earlier sailplane, the 19m (62ft 3.5in) span Fafnir. Dittmar built the prototype Condor in a workshop at Wasserkuppe in his spare time and it made its debut in the 1932 Rhon gliding contest, which it won; its very clean lines aroused considerable interest, and it went into series production.

Introduced in its original formin 1932, the Condor 1, the high-set gull wings were braced with V-struts and had strengthened leading edges. The Condor series was built from wood, with the wooden-framed wing covered in doped aircraft fabric. The landing gear was originally a dolly for take-off, with the aircraft landing on a fixed skid, although at least one was modified to use a fixed monowheel. The wings have balanced DFS-style dive brakes for glidepath control. The horizontal stabilizer is of an all-flying tail design.

Condor I
 
The Condor 2and the IIA, developed in 1935, replaced strut bracing with a cantilever wing with a new wing section of reduced thickness/chord ratio on the outer parts of the wings, living an improved glide angle and lower rate of sink at higher speeds. This version set a new world distance record of 303 miles in 1935 and was a well-known type at prewar gliding contests. The Condor itself was of conventional wood and fabric construction, with very long span ailerons and a landing skid under the fuselage; no monowheel was fitted.
 
In February 1934 a Condor was taken to South America and, flown by Heini Dittmar, set a new world altitude record of 14,272ft for sailplanes, breaking the previous record by nearly 6,000ft. In 1935 one was flown to a new world distance record of 504 km (313 mi).
 
The Condor 3, which appeared in 1938 and was built by Schleicher, had a longer, slimmer fuselage and strengthened cantilever wings which now incorporated DFS air brakes.
 
After the war Heini Dittmar formed his own company, Mowe-Flugzeugbau Heini Dittmar, and there developed a tandem two-seater version, the Condor 4, which first flew in 1953 and was very similar to the Mk 3 apart from the second seat. The two-seat Condor IV was put into series production by Schleicher. The Condor IV has a 18.0 m (59.1 ft) span wing that employs a Goettingen 532 airfoil at the wing root, changing to a NACA 0012 section at the wing tip.
 
Condor IVs were flown in the 1952 World Gliding Championships held in Madrid, Spain. During that contest Ernst-Günther Haase set a new world record in the multi-place category for speed over a 100 km (62 mi) triangle of 80.9 km/h (50 mph).

Condor IV
 
Hans Luenger imported one Condor IV-2 to the United States in 1952. After the wooden fuselage was damaged, he and Merritt Zimmerman built a new design replacement from welded steel tube and covered it with doped fabric. The new fuselage included a fixed wheel for landing gear. This aircraft was removed from the US Federal Aviation Administration registry in 2007.
 
The Condor, also referred to as the Dittmar Condor, single and two-seat gliders were produced in small quantities before the Second World War, produced again between 1952 and 1955 by Alexander Schleicher GmbH & Co and also by Ferdinand Schmetz.
 
Some sources state that there were a total of 18 Condors constructed, while one other says that the total number is unknown, but includes at least 18 Condor IVs built under licence in Argentina.

Peter Reidel's Condor La Falda was modified to have a strut-mounted power-egg, containing a Kroeber M4 driving a pusher propeller, attached to the centre-section. The intention was for the power-egg to be carried to the glider by the retrieve crew, fitted to the glider and the pilot to fly the glider back to home base without the need to de-rig and transport by trailer. In practice it was found to be impractical due to the complexity of the mounting, as well as time and effort required to mount the power-egg.
