History
In 1911, Alliot Werdon-Roe designed an aircraft which he called the Avro 500. The aircraft was powered by a 35 HP engine. In total, 6 such machines were built, and they were used until 1913. Avro quickly gained the sympathy of the pilots thanks to its easy piloting. On the basis of the Avro 500 design, another Avro 504 model was designed in 1913. The prototype took to the air in July 1913. The drive was an 81 horse Gnome. The plane achieved a sensational speed of 107 km / h. Therefore, the military ordered 12 of these machines. Until the outbreak of the war, 63 Avro 504s were built, when the war broke out, orders flowed like an avalanche. 8,340 copies were built during the war alone. Thanks to its good performance and amazing flying properties, the Avro was used for almost everything. He was a reconnaissance bomber plane, he collaborated with artillery. It was even used for hunting tasks. The greatest success of the Avro 504 was the destruction of the airship base in Germany in 1914. 3 machines destroyed the airship and the hydrogen plant. Avro was used throughout the war, but quickly became the equipment of training units. There were 10 different construction versions marked with letters. Avro planes were used long after the war. Even in 1933, its subsequent varieties were produced. Several of them served in Great Britain during World War II. One copy of Avro was purchased by the Polish military aviation. It was used for training in Warsaw until 1926.
