Hi,


the Polish Institute of Aviation or IL developed the RO-H,it was a high-wing light and towing aircraft project,it had a strut braced wing,twin tail fin and tricycle fixed landing gear,and powered by one 280 hp WN-2 engine.

Hi,

Rotodyne design (hybrid of an airplane and a gyroplane). Poland.

In 1948, prof. Zbigniew Brzoska and eng. Ryszard Orłowski from the Institute of
Aviation developed the concept of a rotodine, i.e. a hybrid of an airplane and a
rotorcraft (in this case - a gyroplane). Only a rotor model with a diameter of 2 m
was developed for wind tunnel testing. However, it has not been established
which aircraft was to be rebuilt by the installation of the rotor. One of the
possibilities was LWD "Szpak", which was then undergoing tests at the Institute.

The project was not implemented.

From Technika Lotnicza 1984,

The Institute of Aviation in Warsaw has filed a patent application with the Polish People's Republic Patent Office for a multi-role aircraft (inventors: R. Orlowski, J. Kieroński, M. Kwiatkowski, R. Lewandowski, and J. Parafiniuk). The invention solves the problem of constructing an aircraft with a powertrain that, compared to a turbofan engine, has advantageous features, namely lower hourly fuel consumption, higher takeoff thrust, and reduced noise. The aircraft could be used in agriculture, firefighting, transportation, or passenger transport. An aircraft with a biplane configuration, with two tail booms, having nacelles on both sides of the fuselage connecting the upper and lower wings in a plane of the tail booms, forming a rigid structure with the wings, characterized by having a propeller 1 placed in the housing
