Can they make a helicopter with a jet engine instead of the old big prop.?
A modern helicopter usually has a jet engine powering the rotor. . That spinning thing above the helicopter is not a propeller. It’s known as a rotary wing. It’s what lifts the craft into the air. . Think of it as a wing that is spinning around. Instead of pushing the wing through the air to create lift in rotary wing aircraft the wing is above the craft and spins in place. That is about as simplified as I can express it. . An aircraft held aloft by the power of a jet engine alone would be very inefficient. .
