Turbojet Engines produce thrust by compressing exhaust gas through a propelling nozzle. The exhaust gas jet is composed of high-pressure combustion gases. The pressure created within the nozzle causes the piston to move down and opens the nozzle aperture. These gases then exit the engine and produce thrust. Turbojet engines produce the greatest amount of thrust of any type of engine.
While turbojets generate large thrust, their efficiency is low at low aircraft velocities. Their efficiency increases as aircraft velocities increase. For this reason, supersonic aircraft require high propulsive efficiencies. While turbojets don’t produce high fuel efficiency, they can operate at higher velocities than piston engines.
The Turbojet Engine uses a nozzle and compressor to create thrust. The nozzle is attached to a turbine and drives the compressor through a drive shaft. This turbine then turns a propeller at the front of the engine. The turboprop is similar to the turbojet, but uses a turbine located rearward of the combustion chamber.
Another type of turbojet engine is the ramjet engine. This design works by compressing air and releasing it through a vent. This makes for an increased air temperature. The NK-12 is the largest turboprop engine. It was designed in the 1950s by the Soviet Union. This engine has a four-bladed fan and is 5.6 meters (18 feet) in diameter. It can also be found on jet aircrafts.
The first gas turbine was created in 1921 by Maxime Guillaume. The technology was still not developed at that time, but he was able to patent the idea. The axial flow turbojet had to be invented first. In 1926, the aerodynamic theory of turbine design was published. This was followed by the experimental work at the RAE.
The turbojet engine has several advantages. First, it is very effective at high altitudes. It can fly from continent to continent in a few hours. Second, it is more efficient than piston and propeller aircraft. And third, it can run on higher pressure. It also provides a greater range than domestic aircraft.
The second advantage of a turbojet engine is that it produces high-pressure gas at a high rate. This combination results in a relatively stable average thrust. The engine can also be built with a common crankshaft. This gives it more flexibility. However, a turbojet engine requires a lot of maintenance.
The third advantage of a turbojet engine is that its piston is relatively light. This makes it a light and portable type of engine. The piston shaft are connected to the engine by a connecting rod. The crankshaft is located at the axis of the piston. It is possible to get up to four thousand RPM at full throttle.
Another advantage of a turbojet is that it is quieter. Because of this, it is able to generate more thrust at low speeds.
