  • Aircraft engines – Inline engines in Poland until 1939. – Part 7

    The Lorraine-Dietrich 12 engine was the first in-line engine built in the Reborn Republic of Poland. Department IV of Air Navigation decided to undertake licensing purchases. To begin with, a license was purchased from French Lorraine-Dietrich engines with 400 HP and 450 HP. In December 1926, an agreement was signed between Skoda Polska and the…

  • Aircraft engines – Reciprocating engines in Poland after 1944. – Part 8

    After World War II, the development of medium and high-power piston engines was practically stopped. Only low-power internal combustion engines remained in development. This was due to the revolutionary development of turbojet engines, followed closely by turboprop engines. Unfortunately, the Polish Aviation Industry has practically dropped out of the world leaders. As a country influenced…

  • Aircraft engines – Rocket – Part 11

    In France, a rocket engine of the SEPR type for combat aircraft was developed. The resulting version of the SEPR 841 engine could be mounted on Mirage III C aircraft. The engine was mounted under the rear part of the fuselage with bolted connections. Aviation kerosene is the fuel and nitric acid is the oxidant.…

  • Aircraft Engines – Turbojets in the East – Part 17

    Description to the photo: The Lis-2 engine was produced in Poland, at WSK PZL Rzeszów, under the license of the Russian Klimow WK-1 engine. The Lis-2 engine was used in aircraft of the aircraft family: PZL Lim-2 (single-seat), PZL SB Lim-2 (two-seat).

  • Aircraft Engines – Turbojets in the UK – Part 15

    The De Havilland Vampire combat aircraft was developed in the UK in parallel with the Gloster Meteor. However, unlike him, it received a power unit consisting of one turbojet engine. The engine was placed in a rudimentary fuselage just behind the crew cabin. The first flight of the De Havilland Vampire plane took place on…

  • Aircraft Engines – Turbojets in USA – Part 16

    As early as 1945, engineers at General Electric and Allison set out to develop a turbojet engine with an axial compressor. This is how the design of the TG-180 was born, which later received the designation J35. The engine was developed in parallel with the J33 engine. Some historians believe that the J35 engine was…

  • Aircraft Engines – Turboprop – Part 27

    Despite the Allison T40 program failure, Allison continued to develop a single-turbine turboprop engine, as was the Allison T38 engine. The T56 engine was developed especially for the Lockheed C-130 Hercules transport aircraft. Over several decades, the Allison / Rolls Royce T56 engine has been built in over 18,000 units. The engine was used to…

  • Aircraft Engines – Turboprop – Part 28

    The Soviet Mi-1 and Mi-4 helicopters were powered by piston engines. Turbine engines have already been widely introduced in the West. The Russians managed to obtain the Allison 250 engine. On its basis, Sergei Isotov’s team developed their own engine, which was designated GTD-350. The first engine start took place in 1961. The engine in…

  • Aircraft Engines – Turboprop – Part 29

    In Poland, turboprop engines were encountered in the 60 years, when LOT Polish Airlines received Il-18 (1961) aircraft with Ivcheniko AI-20 engines and An-24 aircraft (1966) with Ivchenko AI-24 engines. The same engines were used in the military An-12 (Ivchenko AI-20, 1966) and in the An-26 (Ivchenko AI-24, 1972). These engines were not produced in…

  • New exhibits at MLP in Czyżyny. 2010.

    I will be the first to mention the extremely interesting Jaguar combat aircraft. It is a supersonic, twin-engine tactical support aircraft, designed for precise attack on point targets with classic bombs, guided bombs and guided missiles. The plane is the fruit of British-French cooperation. For economic reasons, on May 17, 1965, the governments of France…
