The Zlín Z-526 is a Czechoslovak sport and aerobatic aircraft of the Trenér series. The two-seater versions are nicknamed Trenér Master , the single-seaters are known as acrobat and acrobat special . The Z-526 became famous by winning the aerobatic world championship in 1968 in the individual ( Erwin Bläske , GDR) and team (GDR) competition.
development
The Z-526 is the logical further development of the Z-326 . Changes to this consist in the reinforced airframe and engine mount. The engine got a special fuel system developed for aerobatics. For the first time, a fully automatically adjustable Avia-V-503 two-blade made of metal with a diameter of 1.95 m served as a standard propeller.
The first series appeared in 1966 and included the two-seat Z-526 Trenér Master , which was used in particular for aerobatic training, and the single-seat Z-526A . Both had a 118 kW (160 hp) M-137 engine as a drive . The reduced-weight Z-526AF followed in 1970 .
The Z-526F appeared in 1969 as a performance-enhanced version , the first flight of which had taken place in autumn 1968. It had an M-137A engine with an output of 132 kW (180 hp) and was produced in over 150 copies by 1974. Its single-seat counterpart for aerobatics first flew in October 1971 as the Z-526AFS . In this case, the wings and thus the wing area had been reduced, which made it more agile and allowed a higher rate of climb. The landing flaps were completely removed, but the ailerons were enlarged. The canopy was given a more aerodynamic spherical shape. The export variant for the western market was equipped with a Lycoming AIO-360-B1B drive and Hartzell adjustable propeller, was called the Z-526L and flew for the first time on August 28, 1969. Thanks to the more powerful 200-hp engine, it achieved a permissible level Top speed of 315 km / h.
The successor was the Z-726 Universal from 1973, derived from the Z-526F , which also formed the last link in the Trenér series.
A special version for glider tow was created in 1981 under the name Z-526AFM Condor . It has a more powerful M-337A turbocharged engine and a V-410 variable displacement propeller. The wings with additional tanks at the ends were taken over from the Z-326.
description
The cell of the Z-526 consists of a welded tubular steel frame that is planked with metal above and below and covered with fabric on the sides. The two-spar wings are arranged on the fuselage in a low -wing configuration. The tail unit consists of a metal frame covered with fabric. The main wheels of the rear wheel chassis are half retractable into the wings and have a track width of 1.80 m.
Others
The team from the GDR , which was victorious at the World Cup in 1968 , consisting of Erwin Bläske , Peter Kahle and Dieter Kapphahn , flew their Z-526A beyond the permissible +/- loads, but tried to compensate for this by shortening the inspection inspection intervals. A total of eight Z-526A, one Z-526F and eleven Z-526AFS were used on the GST .
During a demonstration on September 1, during the Radom Air Show 2007, two Z-526s belonging to the Polish aerobatic team AZL Żelazny collided in the air and crashed. Both pilots were killed.
On June 29, 2013, a Z-526 AFS approved with the Czech registry (OK-ZRB) crashed during an unauthorized aerobatic flight due to control errors near the main grandstand of Roadrunner Race 61 in the solar park located directly next to Eberswalde Finow airfield . The 47-year-old pilot from Berlin was killed. The event was then canceled.
