It was discussed a while back. It was intended to test wing sections in
free air. The test section goes between the two endplates: I believe the
concept was not a success.

I'd be curious to know why they thought that the second fuselage was
needed and didn't simply fit the test rig above a standard airframe.

This twin fuselage Blanik was designed, built and flown by Sportine
Avicija, the well known Lithuanian glider manufactuer. The aircraft no
lomger exists tho S.A. still receives inqueries about it to this day.

S.A. was a Let authorised repair facility for Blaniks and so knew the
airframe very well.

The reason for its construction was to test airfoils in the "real
world" of flight. The right hand fuselage had data recording
equiptment in it.

I was told that it had a sink rate like a brick. It's life was not
long and the seperate airframes were soon returned to their normal
configuration. One was later written off but I believe one of the
gliders still is active in the Kaunas Glider Club's fleet.

Perhaps on a Janus like this one?

The SL-2P twin fuselage Blaník was developed by Sportinë Aviacija in
Lithuania as a flying laboratory for testing of laminar airfoils. The
specimen profiles are fixed to a supporting frame erected between the
fuselages. This variant is similar in concept to the modified Janus
once operated by the DFVLR (today the DLR, or German Aerospace Center)
for the same purpose.

This twin Blanik was designed, built and flown by Sportine Avicaja the
well known Lithuanian glider factory. SA was a Let Factory authorized
overhaul facility for the Blanik and so knew the airframe very well.
It was an attempt to test airfoils in the "real world". The right hand
fuselage contained data recording equiptment. I am not sure how
successful the project was.

I was told that even without the test rig it sank like a brick. It was
disasembled and the gliders returned to the club, one was later
written off but I believe one is still flying with the Kaunas Glider
Club at Pociunai areodrome.

The SA factory gets inqueries about this glider to this day.
