44M Lidérc

The 44M Lidérc (Hungarian: succubus) was an experimental air-to-air missile developed in Hungary during World War II. It had acoustic proximity igniter invented by Károly Pulváry (Technological University of Budapest). The acoustic device was a highly advanced technology in 1944 and the research of necessary electronics was a quile complex project. The sensor consisted a super-sensitive microphone, and a squelch principle circuit with two electron tube amplifiers. Cutaway plan of the Lidérc: (tortenelem.444.hu)
