Question: Who designed the glider that was the first from the Centro Volo a Vela of the Royal Polytechnic of Milan? Passage:The Arcore was designed at the Centro Volo a Vela (CVV), or Experimental Soaring Centre, of the Royal Polytechnic of Milan by Gildo Preti. It was the third glider to be designed and built there and had a close resemblance to the first of them, the CVV 1 Pinguino. Both were wood and fabric single seat competition gliders, cantilever monoplanes with mid-mounted gull wings. The wings in particular were very similar in all respects apart from the Arcore's greater span. They were built around a single spar, with a plywood covered D-box ahead of it and fabric behind. In plan, they had a constant chord centre section, filling about a third of the span, and outer sections with taper on both leading and trailing edges ending in semi-elliptical tips. The centre section had positive dihedral but there was none on the outer panels. Ailerons occupied the whole of these outer panels, hinged parallel to the trailing edge. Short span airbrakes extended upwards only, mounted just behind the spar at the outer ends of the centre section.
