"Lublin R-XX" - the Polish naval torpedo-bomber

In the late 1930s the Aviation Supply Board ordered a new aircraft for the Polish Navy (Marynarka Wojenna). It had to be a seaplane with a carrying capacity of at least 2000 kg and a speed of 200 km/h. At the turn of 1930 - 1931 three Polish aviation factories: PZL, PWS and joint-stock company "Plage i Laškewicz" from Lublin submitted proposals to design and manufacture a long-range bomber-torpedo aircraft. And they all were a seaplanes. The management of MW chose the plane, offered by the firm of Lublin. A contract was signed for the fleet to purchase 10 units of the R-XX. In 1933 a team of engineers, led by Jerzy Rudlicki started designing the airplane. The biggest problem was the creation of a three-part folding wing structure (this was required by the conditions of Marynarka Wojwnna - the aim was to adapt the plane to railway transportation). The designers convinced the representatives of the military fleet, that such a wing design would have been irrational due to its mass). Finally, the plane is designed with an integral "Fokker"-type wing. In June 1934 the elements of the prototype were transported to Puck, where the plane was assembled and placed "on floats". After a number of modifications (elongated engine mounting frames to improve the centering of the aircraft), the R-XX took to the air for the first time on April 8, 1935. The aircraft required the replacement of some elements (first of all there were problems with the tendency of large shifts of the center of mass during flight), but in general the R-XX was recognized as an advanced design. Its acceleration path was short, and the range of speeds was large (minimum speed was only 80 km/h, maximum - 250). During subsequent flights an error in the fuselage design became apparent. Due to a calculation error, the strength of the fuselage spars was too low and one of them broke during one flight. In October 1935 the company reworked the structure, but in November of the same year the contract with the company was terminated (this was a consequence of the aviation board's policy of nationalizing all enterprises in the aviation industry). No further work was done on the plane and the corrected prototype was at the disposal of the Board of the Ministry of Aviation until 1937.

A large, complex, well-designed and well-detailed model of airplane for intermediate and advanced modelers. The model recreates the appearance of the aircraft from the 1935 test period and can be made in three different levels of complexity.
