The SZD-13 Wampir (Szybowcowy Zakład Doświadczalny - Glider Experimental Works) was a single-seat tail-less glider designed and built in Poland from 1955.
Development The SZD-13 Wampir was a development of the SZD-6X Nietoperz, using a NACA laminar flow aerofoil. Main designer was Irena Kaniewska. Wind tunnel tests on the prototype were not encouraging, so it was not flown, in favor of the more advanced SZD-20 Wampir II.
