Well done evansb, it is the Weserflug P-2147, a four seat amphibian powered by two Hirth 508C engines.
I have very little extra information on this craft. if any one else has more I would like to hear it
evansb has the controls.

Mel, you are very quick in identifying the heritage of the aircraft.
The Bellanca Bimotor Transport was an eighteen-place civilian transport version of the Model 77-140/320 Junior Bomber prototype and seaplane. Designed in 1934, the Bimotor was equipped with the latest blind flying instruments of the day, and had oleo type undercarriage. She was powered by two Wright Cyclone 710-hp geared radials vs. the 715-hp motors of the Model 77. The Bimotor Transport's wing span was 76 feet vs. 77 feet of the Model 77, and an overall length of 44 feet, which was 4 feet longer than the Model 77. Given the wingspans of the aforementioned aircraft, and the fact that the "-320" of the Model 77 referred to the 32-foot long floats, perhaps Bellanca should have called the Bimotor the Model 76. You have control.

Thanks Bri it was the wing planform and faired wing support struts that led me to my reply. The Bellanca Model 66-70 has a similar wing plan form and faired wing supports. I then found the Bellanca 77-140 bomber but could not locate the photo that you has just posted. A great challenge.

Apart from two PMs identifying this aircraft it would seem not to have sucked in any further takers. Time for a clue, this aircraft was a one off and built for research.

sycamore. Not Czech but from a neighbouring country, which in fact had occupied Czechoslovakia by the time this aircraft flew.

A similar project was carried out on an Auster T Mk 7,modified by Marshalls to enable Cambridge University to explore boundary-layer control by suction.

one11 has it 
. As you rightly say it is the AVA AF1. It certainly is an unusual aircraft. Aerodynamische Versuchsanstalt Göttingen (AVA), worked with the suction motor concept on two early experimental aircraft from 1938-40, the AF-1 and AF-2 to study boundary layer control. All flight tests were purely experimental and neither aircraft had a military equivalent. As the Fieseler Fi-156 Storch STOL aircraft fulled the utility role without need of a suction motor for ultra-short take-offs.

Time for a clue I guess. The manufacturer is normally associated with much heavier and faster designs and flew its first jet in the same year as this one got off the ground......
