Inteco L-213 aerobatic glidder
The design of the Czech aerobatic glider L-213A came from the late 1980s. A prototype flew in 1992. The flight test was started, but never completed. Soon it was quiet again around the project and the manufacturing company INTECO disappeared from the scene.
Today only an old brochure and a model kit of a Czech company remind of this really interesting aircraft.
The L-213A had nothing to do with the Blaník family (L-13, L-23 and L-33) of LET Kunovice except for the metal construction. Probably, however, the type designation should suggest a relationship with the tried and tested Blaník.
About the technical details is only as much known, as in the rather poor prospectus. Accordingly, the L-213A was made in all-metal construction, only the rudder surfaces were covered with fabric. The surfaces were connected to the fuselage with three bolts and the tailplane was pushed into the fin from the front. The hood could be placed backwards over the fuselage to open. The chassis was half retractable in the manner of Blaník, i. retracted, the bike partially looked out. The landing aids were narrow rotary brakes on the trailing edge of the wing. The large-dimensioned ailerons stretched over almost 60% of the span.
There is no information on the wing profile used and also the published performance data are incomplete. In view of a specified lowest sinking speed of 1.2 m / s, no miracles would be expected in terms of gliding performance. The indicated maneuver speed VA = 160 km / h is very restrictive compared to e.g. the Swift.
The reasons for the failure of the project can only be speculated. Probably the most likely thing is that the developers simply ran out of money. But otherwise the situation in the early 1990s was anything but favorable for the market launch of a completely new aerobatic glider.
The Poles had just landed with the Swift the absolute hit. Also, the Poles had not designed a completely new aircraft, but in principle reissued the proven Kobuz 3 for 25 years. The Czechs, just like the Romanians with their IAR 35 or Peter Celliers with his Celstar, had to expel their teething problems from their construction before the aircraft had a sales opportunity. But until then, the already tight market would have long been occupied by the Swift.
