In the Avro Type F is a monoplane - airplane of the British manufacturer Avro .
history
At the beginning of 1912, Alliott Verdon Roe began planning an aircraft with a closed cabin - a novelty for the time. He used the landing gear as well as the rudder and elevator of the Avro 500 , whereby the rudder was connected to a steerable tail skid.
The cell of the machine was created in a mixed construction of wood and aluminum. The wings were guyed by a pylon attached to the fuselage and had no rudders, the transverse steering was done by twisting the wing.
In April 1912 the machine was assembled and on May 1, 1912 the Type F took off for its maiden flight. This was the first ever flight of a machine with a closed fuselage.
A Viale 5-cylinder engine already used in a Type D was installed as a drive ; the unit was known and considered to be well maintained. Thus, the critics of this concept, who expressed their skepticism in advance with regard to the pilot's visual impairment due to the contamination of the windscreen by oil leaking from the engine, were not confirmed.
In early May 1912, several test flights took place and on May 17, the first flight altitude of 1,000 feet (304.8 meters) was reached. So it was decided at Avro to demonstrate the Type F publicly in Hendon on May 25, 1912 . However, the engine failed immediately after the start and works pilot Wilfried Parke had to make an emergency landing. He hit a fence and the plane overturned. After all, during the subsequent dismantling of the only slightly damaged machine, it was possible to prove that the aircraft could be completely dismantled for transport by four men within 25 minutes.
The machine was not put back into operation until September 13, 1912. When attempting to take off, however, the skid broke, and the subsequent landing resulted in a rollover. This time, however, the damage was considerable, and the Type F was no longer used afterwards. The machine remained a one-off and was never mass-produced.
The Type F Viale motor is on display at the Science Museum in London .
construction
The Avro Type F was a middle-decker with a partially fabric-covered fuselage, partially clad with wood and aluminum. The wings consisted of a covered wooden structure. The landing gear consisted of a two-wheeled main landing gear with an intermediate skid and a steerable tail spur.
