TST-13 Junior is a single-seat ultralight
composite glider with an engine installed in the
front part of the fuselage. The aircraft is
suitable for tourist flights and leisure thermal
The goal of the development work on the TST-13 was
to design an ultralight aircraft for pleasurable
flying and to feature aerodynamics to allow
utilization of thermal conditions for gliding and
motorless flights. The concept of the TST-13 is
based on the high-performance TST-10 Atlas glider.
We used the same wing span of 15m and the fuselage
of the TST-10 was modified to enable the
installation of the propulsion unit with a thrust
propeller in the front part of the fuselage. The
fuselage of the TST-13 features an instrumentation
panel and design conforming to the category of
ultralight motorless aircraft. The landing gear is
fitted with two wheels with a controlled tailwheel.
