Fighter aircrafts have the jet engines buried inside the fuselage

In summary, fighter aircrafts have their jet engines placed inside the fuselage for several reasons. This allows for more space in the wings for cargo and missiles, increases maneuverability and decreases air resistance. Fighter jets also use low bypass turbines which are more suitable for their needs. This placement of engines also allows for a smaller turning radius, making it easier to avoid enemy fire.

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?

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.

Yeah, sorry.

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!
 

Related to Fighter aircrafts have the jet engines buried inside the fuselage

1. Why are jet engines buried inside the fuselage of fighter aircrafts?

The placement of jet engines inside the fuselage allows for a more streamlined and aerodynamic design of the aircraft. It also helps to reduce drag and increase the overall performance and maneuverability of the fighter aircraft.

2. How does burying the jet engines inside the fuselage affect the weight distribution of the fighter aircraft?

By placing the jet engines inside the fuselage, the weight is more evenly distributed throughout the aircraft. This helps to improve the stability and balance of the fighter aircraft during flight.

3. What advantages do buried jet engines provide in terms of stealth capabilities?

Burying the jet engines inside the fuselage can significantly reduce the heat and noise signature of the fighter aircraft, making it less detectable by enemy radar and reducing its overall visibility.

4. Are there any disadvantages to having buried jet engines in fighter aircrafts?

One potential disadvantage is the increased complexity and maintenance required for the engine placement. It also limits the size and type of engines that can be used, which can affect the overall performance of the aircraft.

5. How do fighter aircrafts with buried jet engines compare to those with external engines?

Fighter aircrafts with buried jet engines generally have better performance and higher maneuverability due to their streamlined design and evenly distributed weight. They also have a lower radar cross-section, making them more difficult to detect by enemy radar.
