VTC Delfin
type of aircraft
The VTC Delfin is a competition single seat Standard class glider designed and built in Yugoslavia in the 1960s. It had some success in national competitions and went into small scale production.
Design and development
A standard class single seat sailplane with a wooden structure and largely plywood covered, the Delfin has a 15 m span (49 ft 2.5 in) shoulder mounted wing of straight tapered plan and with small tip fairings or salmons. There is 2° of dihedral. Forward of the spar the wing is wooden skinned; the first seven aircraft, the Delfin 1, use ply-foam sandwich but this was replaced with all-wood layers in the production Delfin 2. Behind the spar the covering is fabric. The Delfin 1 has metal ailerons, replaced with all-wood ones in the Delfin 2. No flaps are fitted but there are Schempp-Hirth airbrakes mounted at 60% chord.
The oval cross-section fuselage of the Delfin tapers gently to the rear to an integral fin. All Delfins were built with a fin and rudder strongly swept on both leading and trailing edges and with an all-moving tailplane, fitted with servo tabs, mounted on the fuselage.

Why this record matters
A short description can identify a subject without explaining its stakes. For “VTC Delfin”, the useful work is to connect “type of aircraft” to the records capable of establishing context and consequence.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Dec 26, 2025. The linked authority identifier is Q7907610. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
