The Focke-Achgelis Fa 330 "Wagtail" was a motorless small gyroplane intended for use on submarines and ships.
description
The machines could start at a speed of 30 km / h. They were propelled and lifted up ( autorotation ) solely by the speed of the submarine and the wind . The structure was extremely simple and consisted of a tubular steel construction and a main rotor measuring 7.31 m in diameter , which consisted of three rotor blades.
The gyroplanes could be folded up. They were not stowed in the interior of the ships or submarines, but in two large pressure vessels (60 cm in diameter) that could be closed with watertight lids and were mounted vertically on the tower of the submarine. One of the containers contained the three rotor blades and the hub, the other fuselage structure, controls and tail unit.
The launch took place from a launch table that was mounted in the so-called winter garden of the submarine. The individual observer had a greatly increased range of vision, which should improve the location of targets. If the visibility from the tower of the submarine was usually no more than 5 nm , the observer from the wagtail could see 25 nm, as the gyroplane reached a height of approx. 120 m on the 300 m long tow rope.
It took seven minutes to get the machines ready for use on a submarine, and they were packed in two minutes. In emergencies, the pilot could drop the rotor and land with the rest of the machine hanging from a parachute . More than 112 of these simple, but technically sophisticated devices for their time were built and used on the Type IX D 2 submarines .
Around 200 copies of the Fa 330 are said to have been assembled at Weserflug in Hoykenkamp. Some of these came to Britain in 1945 and were investigated at the Airborne Forces Experimental Establishment , RAF Beaulieu. Another prototype was completed after the war in France as the SNCASO SE-3101.
Since the use of a submarine prevented the submarine from descending quickly (or required abandoning the aircraft and leaving the pilot behind), the success of the model was very limited. Subsequently, the possibility of modifying the Fa 330 into a helicopter using a 60 hp engine was examined, but it was not considered feasible. Instead, the outwardly quite similar, but largely independent Fa 336 was designed. The concept also included a 60 hp engine and a conventional tail rotor for torque compensation, but never got beyond the drawing board due to a lack of development capacities.
