Polish projects since 1945

[blockhaj]

Also for Institute of Technology Aviation (ITL),there was two projects;


one was Aerofoto 48,it was single seat twin boom pusher aircraft,and the second M.48
was jet fighter and fighter-trainer combat aircraft.

Are there any linedrawings of the M.48 fighter trainer?

 

[Petrus]

It should be noted that the ITL M.48/ITL-48 was not to be a jet fighter. Its planned engine was the Jumo 211, many of which (with propellers) had been taken over by Polish authorities after the war.

But where there any plans to make jet fighters/trainers which where to be armed?

The Aerovan was a project for twin-engined high-wing light STOL
transport aircraft.

And here is a 12-seat Project,developed from Aerovan,but had a tandem wing.

Hi,

the CSS-14 was production of Gotha Go.242M

Hi,

the CSS-14 was production of Gotha Go.242M

Indeed the CSS-14 was a probable designation of a proposed Go-242 conversion (the conversion has been also referred to as the CSS-242M). After WW2 there were quite a few Go-242 gliders at several airfields in Poland abandoned by the Luftwaffe. So the idea came up to rebuild them into someting along the lines of the Go-244 using captured German engines. In 1948 a project of such a rebuilt was prepared. The aicrcrat was to have BMW-132 engines.

As for the CSS-15 here you've got a scan of the original drawing of the project (with the BMW-132 engines):

There was also another version of the CSS-15 with the Bramo-323 Fafnir engines.

M-9 Ziemowit* trainer project of 1959 (construction team: Stanislaw Jachyra, Adam Borowski, Marek Augustynik) from PZL-Mielec. Span 8.15m, length: 9.2m. It was to be powered by the TO-1 jet engine (by Tadeusz Mirski) that was to develop 400kp thrust.


* Ziemowit is a Polish male first name, also known as a name of a legendary ruler of ancient Poland.

Is that a single-face centrifugal compressor?

Indeed the TO-1 had a single-stage centrifugal compressor.

Hi,

Fire-Fighting Airplane design.

Dr. Eng. In the mid-1980s, Stanisław Danilecki conducted research on the closed wing system. At that time, he developed concept designs for a fire-fighting aircraft with a minimum lifting capacity of not less than 3500 kg and an ultralight sports aircraft in such a system.
The aircraft was designed in a variant of the closed wing system, which was characterized by the fact that the horizontal tail is formed by the surfaces outside from the point of contact of both wings, connected in one line. The point of contact of both pairs of airfoils was in 2/3 of their span. The position of the control surfaces was as follows: elevator on the inside of the aft pair of airfoils, ailerons on the outside parts behind the contact point, flaps on the inside part of the front pair of airfoils, rudder on the tailplane.

The analysis of the advantages of the closed wing system for an aircraft intended for firefighting conducted by the author of the project showed that it was possible to obtain approx. 10% higher climb speed, the weight of the load may increase by 50% and the speed range will increase by approx. 10% compared to the design classic.

Hi,

Design of an amateur sports plane. Poland.

In 1987 Marian Górniak, an amateur constructor, had a ready plan of a light aircraft, the construction of which would take about a month. The constructor was looking for a sponsor who would finance its construction. Probably, due to financial reasons, this project was not implemented.

[Apophenia]

The publication Lotnictwo (Aviation) published an appeal in issue No.35 (16-31 March 1994) to raise donations for both Marian Górniak and Jarosław Janowski. It was dubbed the Fundusz Uparci Lotnicy - The Stubborn Aviators Fund

I assume for the project in question for Janowski was the J-7 Fregata, an unbuilt two-seat development of the J-6 motor-sailplane.

Thank you dear Apophenia,

and here is the article.

Aerobatic plane design. Poland,

In 1972, Krzysztof Hipolit Piwek obtained a diploma from Energy
and Aviation of the Warsaw University of Technology,for the
aerobatic plane Project.

Ultralight sports plane project. Poland.

In 1994, the Yalo Floating and Flying Equipment Plant carried out design work on
the Yalo 1 two-seater ultralight sports plane.The design of the plane was probably
not implemented. No further information available.

Some recent Warsaw University of Technology programs and prototypes.
I don't know the names of all the prototypes, but the last one sure looks intriguing.

From this book.

This is a Mig-17 that had in fact conform fuel tanks around the base of the wing, and have heavy duty landing undercarriage with doubleed wheels. It was suppose to be polish premier attacker. Engeniers in Poland considered making a "traditional nose with moving intakes to the sides, but MiG did not allow as this would be a change to the structure of the planes.

Hi,

in 1949,the Section Aviation Mechanics Wheels Students Warsaw University of Technology designed SLPW-1,a two-seat low-wing sporting aircraft Project,powered by one 90 hp Cirrus Minor engine.

http://www.samolotypolskie.pl/samoloty/1888/126/SLPW-1

From Technika Lotnicza 1982,

In 1949, the Aviation Section of the Warsaw University of Technology Student Mechanical Association conceived the idea of maintaining the Section's long-standing traditions of aircraft construction.

The initial design of the SLPW-1 sports aircraft was developed by student B. Młodziejewski, who completed it in December 1949. The design was inspired by the best sports aircraft from the last years before World War II.

The SLPW-1 was a two-seat, wooden, low-wing monocoque monoplane with a semi-monocoque design, with one crew seat behind the other and a retractable landing gear. The aircraft's total drag coefficient was to be Cr = 0.0215 at Cz = 0.25, giving an aircraft glide ratio of 11.5. The wing was to be equipped with flaps to achieve Cz max = 1.9. Power was to be provided by a four-cylinder Cirrus Minor 64 kW (90 hp) inline engine or similar. The tanks were to have a capacity of 80 liters. The aircraft's technical specifications appear to be overly optimistic.

The design and implementation of the project were never completed due to the dissolution of the Aviation Section in 1950 due to false political charges brought against its board members. Moreover, the conditions prevailing in the country at the time would not have allowed the aircraft to be built, as it was a period of liquidation of domestic aircraft design activities and the restriction of social initiatives in the field of aviation, particularly attempts to build aircraft outside the industry.
