Fighter aircrafts have the jet engines buried inside the fuselage

    Unlike commercial airplane, many fighter aircrafts have the jet engines buried inside the fuselage instead of in pods hung beneath the wings. Do you know why? :surprised :surprised

    Passenger planes, bombers, cargo transports, etc. need the space in the fuselage for cargo. For that reason, they place the engines on the wings.

    The fighter jets generally need to go fast and be maneuverable. They also want to have a small profile to help avoid radar/guns/missiles. Additionally, it's easier to reload and launch missiles if they're based on the wings. You just drop them and away they go: no needing to worry about opening any doors or hatches.

    The moment of inertia along the longitudinal axis is also kept small by placing the engine inside the fuselage, increasing maneuverability. Another benefit would be lower air resistance.

    Off the top of my head, the fighters use low bypass turbines which have a much higher SFC than high bypass engines such as those used on commercial and transport craft, thus making them inappropriate for this type of use.

    Specific fuel consumption?

    from my knowledge but don't quote me on this fighter jets have their engines closer to the fusalage because they need to have a smaller turning cicle so of the engines were on the wings it would mean that the plane has to put in more effort to turn as it has to move the engines round and so slow the plane down which as you probably know is not very helpful when having someone on your tail firing off missiles at you left, right and centre.



    a day without sunlight............is like.................well.........................scary!!
