Aero-engines – Powered-lifters – Part 25
The Rolls Royce Pegasus engine is one of the most remarkable turbojets in aviation history. The Rolls-Royce Pegasus, formerly the Bristol Siddeley Pegasus, is a turbo-fan engine designed by Bristol Siddeley. The engine was specially designed for the combat aircraft that eventually became the Harrier.

Aircraft Engines – Gas Turbine – Part 13
Since a turbojet engine is a heat engine, all the laws of thermodynamics apply to it. The engine starts with an air gulp and an air intake duct. Its length and diameter are different and depend on the parameters of the turbojet engine and the speed achieved by the aircraft. The air intake is usually…

Aircraft Engines – Geared Turbofan – Part 23
Work on turbo-fan engines with a gearbox resumed at the turn of the century. There were several reasons for this decision. First; Such an engine, despite the use of a transmission, has a lower mass in terms of mass-thrust ratio. Secondly; has lower fuel consumption. Thirdly; emits fewer harmful chemicals into the atmosphere. Fourthly; emits…

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 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…
