CWL Aircraft and Projects

[hesham]

Hi,


the well known Polish CWL company created many aircraft and projects,and
it had a series from WZ-I to WZ-XIV,the WZ-IX was a three engined low-wing
medium bomber monoplane project,its crew were a three,and powered by
three 450 hp engines,its name was Pteranodon.

Re: CWL WZ-IX Pteranodon Bomber Project

With that name "Pteranodon" I was expecting a Dino-plane


Thanks for the link hesham. I always can see another project from this period.

Hi,

Mr. Wladyslaw Zalewski was a well known designer of early Polish aeronautical period,he created his first airplane,the WZ-I,it was a
historical biplane powered by either 20 or 28 hp engine,followed
by WZ-II,a glider of 1912,the WZ-III & WZ-IV was a two-seat quadruplanes,intended for recce role,powered by one 80 hp Gnome
Lambda and 100 hp Gnome Monosoupape B-2 engine respectively.

The WZ-V was also two-seat recce quadruplane airplane of 1917,
powered by one 220 hp Renault engine,the WZ-VI was heavy bomber Project,powered by four 200 hp engines,the WZ-VII was a single seat quadruplane fighter Project of 1919,powered by 100 hp Le Rhone 9 engine,the WZ-VIII De-Ze-Pe was tandem two-seat observation biplane Project,powered by one 360 hp Rolls Royce engine.

We spoke about the WZ-IX Pteranodon in early of this topic and the
WZ-X was a two-seat recce biplane of 1926,powered by one 450 hp engine,the WZ-XI Kogutek I was shoulder high-wing sporting and light monoplane of 1927,finally the WZ-XII Kogutek II & WZ-XIV Kogutek III
was a single seat sporting and light high-wing monoplanes of 1937.

Hi,

also this designer created an ornithopter plane and a two biplane
and monoplane Fighter Projects,powered by a pusher propeller
mounted at the second half of the fuselage in very strange shape,
concepts of 1922-23.

Heavy bomber plane project. Poland / Russia,

During World War I, Władysław Zalewski served as a mechanic in the workshops of the 2nd Aviation Park, stationed first in Warsaw and then in Smolensk. The technical head of these workshops was Vladimir Saviev, a former employee of the Russko-Bałtijskij Wagonnyj Zawod factory, where he worked on the construction of Sikorski's planes. In mid-1915, Sawielew and Zalewski established cooperation. Sawielew had the idea of building a bomber more powerful than "Ilia Muromiec", but - thanks to a five- or six-plane arrangement - of smaller dimensions. He proposed Zalewski to design and build such an airplane.
The drawings of the plane they developed in Smolensk come from September 19, 1915. They present a two-seater, four-wing bomber plane, in the front - in the fuselage axis - armed with a machine gun. The authors of the project assumed that the aircraft, with three Cheneau engines of 184-191 kW, would develop a speed of 135 km / h over a distance of 1,800 km.

Zalewski put forward a proposal to start joint work from the construction of a small single-engine four-wing in order to gain experience and check the concept. In April 1916, the construction of such S.Z.-1 (WZ-III) aircraft was completed.

More Info,
in the years 1922-1923, Władysław Zalewski developed preliminary designs for two fighter planes with a four-bladed propeller in the fuselage behind the cockpit and a machine gun in the front of the fuselage.

The first of them, a biplane, powered by a 220 kW (300 HP) Hispano Suiza engine, with Lamblin radiators under the wings, and the second - a monoplane. These projects have not been implemented.

Technical data biplane fighter (according to [1]):
Span - 8.6 m, length - 5.8 m, height - 2.6 m, bearing surface - 22 m2.
Total weight - 950 kg.

Technical data of the monoplane fighter (according to [1]):
Span - 10.0 m, length - 6.5 m, height - 2.5 m, bearing surface - 12.5 m2.

Stumbled over some new Zalewski/CWL articles. Enjoy.

What was CWL D.1 Cykacz ?.

 

[Cy-27]

CWL D.1 Cykacz was a small single seat wooden biplane designed by Students of the Aviation Section of Warsaw University of Technology. Proposed as an experimental design by J. Dabrowski. First flight by Z. Babinski at Mokotow airfield on 25th February 1925. Initial problems due to tail skid digging in.

Cantilever wings. Designed for a 12hp Salmson or 16 hp Blackburne engine. Later modified tail and airscrew the handling improved at 40 short flights were made, despite an underpowered engine. Led to the D-2.

Length 5.0 m
Wingspan 3.7 m
Height 1.65 m
Wing Area 8.12 sq m
