Design and development
editAround 1990, Czech company Moravan Otrokovice started a project to modernise its Zlín Z 42/Z 43 family of light aircraft.[3] The redesign proved so complete that the company treated it as a new project with the designation Z 90 and displayed a mockup of it at the 1991 Paris Air Show.[3][4] However, market conditions at the time were unfavourable, and work on the Z 90 halted without the aircraft entering production.[4] Some work that had been done on the Z 90 was used in the Kappa 77 KP 2U-SOVA ultralight design, which allowed aspects of the design to be proven in practice.[4]
By 2001, the market for general aviation aircraft had recovered sufficiently for the Czech Ministry of Industry and Trade to sponsor a new project to continue development of the Z 90 under the name VUT100.[4][5] This project would be a collaboration between different Czech aviation manufacturing companies and the Institute of Aerospace Engineering at the Brno University of Technology.[3][4]
The aircraft features a cantilever low-wing, a four-seat enclosed cabin, retractable tricycle landing gear and a single engine in tractor configuration.[1]
The VUT100 is a hybrid construction of metallic and composite materials. Its 10.2 m (33.5 ft) span wing has an area of 13.11 m2 (141.1 sq ft) and mounts flaps. The engines fitted vary, depending on the model and the cabin is 1.22 m (48 in) in width. The VUT100 is stressed for +3.8/-1.52g in the normal category and +4.4/-1.76g in the utility category.[1][6]
Although designed to European CS-23 and American FAR-23 certification standards, the VUT100 does not currently have a type certificate issued by the European Aviation Safety Agency or the Federal Aviation Administration.[7][8]
