In the middle of the 30. years vagonka Gotha (Gothaer Waggonfabrik And.G.) proceeded to work on the bezocasých aircraft, designed by Dr. And. Kupperem from the company Akaflieg München and in general the layout similar also neuspěvšímu machine Westland Hill Pterodactyl Englishman Hill in 1934. The main objective of this work was to create a heavier fighter with a great angle of the shot from the rear range. For the purpose of the research of the controllability of such aircraft at low speeds was in 1935 as a first step, built a small experimental monoplane, which from the RLM received the type designation of Go 147.Later, after the decision about the construction of the second, revised prototype was uznačení changed to Go 147A.
Wooden two-armed wing was strut of kapotovaných steel pipes. The entire trailing edge of the wings of the type "the seagull" with the sweep of the leading edge 38 degrees, with the circular surfaces of the guideposts at the ends, cutting a slit elevonové flaps. Nezatažitelný rear chassis was fixed to the bottom of the fuselage with two struts, the main spring loaded undercarriage legs were hinged anchored to the sides of the fuselage.
Short člunovitý torso long 6,3 m conceived the 2 crew members (pilot and observer/rear gunner), placed behind each other in the cabin under the wing. It was made as a structure welded from steel tubes covered with canvas, only the fairing of the engine was made of duralumin sheet. The two open seats were behind. The stern of the hull grew to a vertical sharp edges.
As the drive was used air-cooled 7 cylinder radial engine Siemens Sh 14A on the performance of 140 pieces, hidden under the cover of the type NACA and driving a fixed two-blade wooden propeller. The wing was a trifold, double-girder, a wooden structure, on the bottom side covered with plywood and on the upper side of the cloth. Nešípovitá the middle part has been downloaded to the hull in the shape of a sharp In and adjacent to the outer part of the wing in the angle of the arrow 38°, which were to the torso anchored struts classic shape N when the front part of the N led down to the bow of the hull and the remaining portion to the bottom edge of the fuselage. Prototype Go 147A was in the autumn of 1936 finished and already during the first test flight it turned out that the machine is completely unstable along all axes. Although changes have been made, no substantial improvement it did not lead. During low speed flight have been the control of the machine almost impossible.
Although during the tests of the first prototype have been identified serious problems with the stability itself of the concept of the doubts start. He was therefore ready and the other test Go 147B, of course, thoroughly rebuilt. Received less directional tail surfaces with a modified shape and integrated flaps having also the function of the wings, also the elevator and lift the flap were to increase the efficiency of magnified. Margin was about 1.25 m is reduced, as well as the tail wheel, which also received a coating. As a driving mechanism was installed more powerful Argus As 10C on the performance of 240 pcs. Fabric covering the fuselage and wings was for the most part, replaced with plywood, only the helm remained coated with a substance. Because the machine was intended also as a trainer for observers and on-board the shooter and also as a light observation and also a homing aircraft for artillery, was the Go 147B also armed. Loadout should be composed of a synchronized machine gun MG-17 operated by the pilot and movable machine gun MG15 in the rear cockpit.
The machine with the civilian registration D-IQVI was finished in the autumn of 1937 and in December 1937 launched for its first flight. Flight characteristics and achieved performance again disappointed, so after a series of improvised changes came in the summer of 1938 the definitive end of all tests, and at the same time RLM ordered cessation of development and the scrapping of the two prototypes.
Note - in some sources there are machines referred to as Go 147 V1 and Go 147 V2.
