Helicopter is very useful aircraft because it can vertically take off and land in a very limited space, turn in any direction very quickly and hover in air. It is powered by an engine on its top with blades which rotate at high speed to give the craft its lift
The helicopter is very useful aircraft because it can vertically take off and land in a very limited space, turn in any direction very quickly and hover in the air. It is powered by an engine on its top with blades which rotate at high speed to give the craft it lifts. The word “helicopter” is adapted from the French hélicoptère, coined by Gustave de Ponton d’Amécourt in 1861. It is linked to the Greek words helix/helikos (“spiral” or “turning”) and pteron (“wing”).
