What is a SZD-24?

The SZD-24 Foka series were Standard class gliders of predominantly wooden construction with fixed wheel and skid undercarriage. The fuselage comprised a wooden structure with the cockpit in the extreme nose transitioning with very clean lines to the integral fin at the rear.

Why was the SZD-24-2 fitted with reduced area ailerons?

The SZD-24-2 Foka 2 was fitted with reduced area ailerons to reduce drag, but roll control was dramatically reduced. The sharply swept fin (used to increase control power and stability with a smaller fuselage, reducing weight), was integral with the fuselage and supported the plywood skinned tail plane at approx ⅓ fin span.

How can SZD-24-2 Foka 2 reduce drag?

A single SZD-24-2 Foka 2 (SP-2362) was built, incorporating attempts to reduce drag by improving laminar flow and reducing the area of the ailerons.
