I Ae 34 "Clen Antú" (Sunbeam)
The project of this two-seat tandem glider begun in 1948 and was concluded one year later. Three units were built and the first was flown in 1949, June 20 with capt. Edmundo Weiss at the controls. 

The project was intended to cover some basic necessities: 

  • To provide a two seat training glider capable to fly for extended periods in thermals .
  • To provide good visibility for the instructor while the student practiced "blind flying" over instruments.
  • To provide an adequate glider for the student first "solo flight".
  • To provide an adequately stressed airframe for aerobatic maneuvers and easily adaptable for a powered glider.
  • To provide a high performance competition sailplane.
  • Its structure was built in wood (3 pieces) and could be assembled / disassembled by 4 people in few minutes. The wings were entirely covered with plywood. it had elevons and flaps along the trailing edge, with drag - rudders near the wing tips and terminal velocity dive - brakes in the wing central section, and near the root.  

    The fuselage had a width of 60 cm., a two wheel tandem landing gear with a skid in the front, and a rear seat 30 cm. above the front one to improve visibility of the instructor. A single instrument panel is visible from both cockpits. Provisions for an oxygen reserve of 3 hours and seat parachutes were included.
