The Aero A.30 was a two-seat biplane - Aircraft of the Czech company Aero Tovarna letadel Dr. Kabes , which was mainly used by the Czech Army aviation as a long-range reconnaissance aircraft and light bomber . The machine was developed as a further development of the relatively successful Aero A.11 .
history
At first, in 1925, Aero made attempts to equip the A.11 with the 450 hp Lorraine-Dietrich, but the A.11 airframe proved to be too weak for this engine.
A new airframe was developed in 1926, overall larger than that of the A.11 and with a larger upper wing area. A Skoda engine was used in the A.30 instead of the originally planned Lorraine-Dietrich, but the A.230 variant received the Lorraine-Dietrich.
Due to the shortcomings that emerged during the first test flights, constant improvements to the details of the A.30 were necessary; Overall, it took about a year for the engineers to be satisfied with their design.
For two months, an Aero A.30 held the world speed record for a 500-kilometer flight with a payload of one ton. The machine reached an average speed of 213.56 km / h in August 1927.
