What is the airplane called that has 8 propeller engines?

There isn't a single airplane model that is *commonly* known to have 8 propeller engines. It's possible that some custom-built or experimental aircraft might have this configuration, but it's not typical.

Here's why:

* Efficiency: Propeller engines become less efficient at high speeds. An airplane with 8 propellers would likely struggle to reach high speeds due to the drag created by so many propellers.

* Complexity: Maintaining and operating a large number of engines increases the complexity of the aircraft and the potential for mechanical issues.

* Weight: Adding 8 engines adds significant weight to the aircraft, which negatively affects fuel efficiency and maneuverability.

Examples of airplanes with multiple propellers:

* Lockheed C-130 Hercules: This military transport aircraft has 4 turboprop engines.

* Antonov An-225 Mriya: This cargo plane, sadly destroyed in 2022, had 6 turbofan engines.

If you're looking for an airplane with a very specific configuration, it's important to be precise in your search. You could try searching for "aircraft with 8 propellers" or "multi-engine aircraft" to see what comes up.
