Göppingen Gö 4
The Gö -4 ( abbreviation for Göppingen 4, also called Goevier ) is a glider in timber construction.
History
With the two-seater Gö - 4, a school and training aircraft with side by side seats was created by Wolf Hirth and Wolfgang Hütter on the basis of Gö -3 Minimoa first time. This is unusual for gliders because the tandem arrangement is preferred with one behind the other seated pilots because of the possible lower cabin cross-sections for reasons of flight performance.
In the autumn of 1937, a two-seater made its debut flight. The Gö -4 was specifically designed as a training aircraft. The Gö -2 had the disadvantage that the seats were arranged one behind another, sat in the Gö -4 teachers and students now pedagogically optimal side by side. In order to keep the torso still as narrow as possible, found outside shoulder and arm of each occupant in the wing root area. The fuselage width was thus only 92 cm. This detail was due to drafts Ulrich and Wolfgang Hütter.
Meanwhile, the rooms in Göppingen had become too small for the increased production. With the series production of Gö -4 was started in the new location Kirchheim unter Teck.
After the pattern approval in February 1939, the glider was at the company Göppingen Martin Schempp Sportflugzeugbau in the series production. We have built a total of 120 pieces.
Construction
The aircraft is a cantilever mid-wing monoplane. The fuselage and wings are made of plywood. The rudder is cantilevered, braced tailplane down.
Use
The Gö -4 belonged to the time of their structure to the high-performance gliders and was also used in competitions and training. From the 1st - 3rd June 1939 flew guide Inger and Hofmann on Hundsheimer Kogel 49 hours and 45 minutes a new world record time.
Aircraft received
Today, only a few exist Gö -4, which are flown and maintained by vintage car clubs. A Goevier is exhibited in the flight Schleißheim.
