Avro Type F
The Avro Type F is a monoplane aircraft of the British manufacturer Avro.
History
Beginning of the year 1912 began Alliott Verdon Roe with the plans for an airplane with an enclosed cabin - a first for its time. He reached back on the chassis, and the pages and elevator of the Avro 500, where the rudder was connected to a steerable tailwheel.
The cell of the machine was in a mixed construction made of wood and aluminum. The wings were braced by a motor mounted on the fuselage pylon and had no oars, the Control is achieved via wing twist.
In April 1912 was the installation of the machine and on May 1, 1912, the Type F rose to the first flight. This was the first flight of a machine with a closed hull world.
When a drive is already used in a Type D Viale - 5-cylinder engine was installed; the unit was so well known and was considered well maintained. Thus, the critics of this concept, which due to the pollution of the windshield due to leaking from the engine oil expressed their skepticism in advance with respect to the visual obstruction of the pilots were not confirmed.
In early May 1912, several test flights and a flight altitude of 1,000 feet ( 304.8 meters) was achieved for the first time on May 17. So it was decided at Avro, the Type F on May 25, 1912 public performance in Hendon. However, failed immediately after starting the engine, and factory driver Wilfried Parke had to make an emergency landing. He hit a fence and the aircraft overturned. After all, it could be proved in the following after dismantling the only slightly damaged machine that the plane could be completely disassembled by four men in 25 minutes for transport.
It was only on 13 September 1912, the machine was put into operation again. At the start of tests, however, broke the skid, and during the subsequent landing it came to the turn -over. This time the damage was, however, significantly, the Type F was not subsequently put into operation. The machine was a single piece and was never produced in series.
The Viale engine, the Type F is exhibited in the Science Museum in London.
