The engines propel the airplanes.
Helicopter engines require substantial power to propel the helicopter vertically from a standstill. With regards to planes, yes obviously planes need powerful engines, BUT planes speed up to 200km/h on runways before they start flying.

Yes, jets are planes but jets are mostly known as supersonic planes.
Smaller planes have piston engines, but bigger planes like the Boeing 717-777 and other planes have turbine engines

Some examples of reaction engines in airplanes are turbofans and turbojets.
its engines
Ion engines only work in the vacuum of space.
You have to have at least one. (If you don't have an engine, your are classified as a glider.) The largest planes typically run 4 or 6 jet engines. Most planes have 1,2,3,4 or 6 engines. Very large aircraft sometimes have more. There are propeller planes, turbo prop and jet engines. There are also VTOL Vertical TakeOff and Landing planes, such as the Harrier and Osprey
BMW is a beautiful car but the first car of BMW was built in 1928 with the motor bikes not cars.They first started making engines for planes that why the logo of BMW is like that because it represents the front propel er of a plane.
