  • Dimensions of a Jet Engine

    The dimensions of a jet engine vary with its various Jet Enginetypes which include the turbojet, turboshaft, turboprop, and the turbofan jet engines. Although they all work on similar principles, each are made with different dimensions that people operating these particular engines should learn more about.

    To understand the different dimensions of a jet engine, here are some things you should bear in mind:

    The Turbojet

    A turbojet actually fits an afterburner just like the turbofan jet engine. This afterburner refers to the long tube that can be found in the middle of the nozzle and the turbine. This is where more fuel is burned to provide a stronger boost for the fuel consumption.

    The parts that you can commonly find in a turbojet engine includes: The inlet, the low pressure compressor, the high pressure compressor, the high pressure turbine, the low pressure turbine, the burner and the nozzle.

    If you have an afterburner included, the parts that you would find would include: The fuel spray bars, the flame holder, the adjustable nozzle, and the afterburner duct.

    Typical dimensions for this are about 920 mm for its diameter, about 2000mm for its depth, around 80mm for wall thickness and the water level height used is approximately around 1100mm.

    The Turboshaft

    A typical model of a turboshaft engine has the following parts: A nozzle, a rotor drive shaft, turbines, inlet, compressors, burner, and particle separator.

    The most common dimensions for the turboshaft includes: 43 by 23 by 23 for its length, width, and height measured in inches. Weight is about two hundred and above in pounds.

    The Turboprop

    A turboprop type of jet engine is also just like a turbofan, but it relies on an external propeller instead of a turbine for working at its high fuel efficiency.

    These types of jet engines are usually used in long-range aircraft and commuter planes.

    Some of the dimensions for these are: About 32.4 m for its length, around a span of 40 m, a height of about 11.67 m, and a payload of about 20,000 kg.

    Some models have a fuel capacity of around 291 US Gallons or 1100 liters.

    The Turbofan

    Those who are really familiar with jet engines say that the turbojet and the turbofan have many similarities. The only difference is its fan section that can be found at the front side of the compressors.

    Turbofans can be grouped as a low-bypass turbofan and a high-bypass turbofan. The external dimensions are approximately around 56 by 92.5mm for its length and diameter. Some rack dimensions are around 625mm by 630mm.

    These dimensions of jet engines cater to the different types available. While there are standard dimensions, some external parts can actually be tailored to suit your needs and still be able to retain a jet engine’s functionality.
