Lets start this way. In the 15th century A man named Leonardo davinci first proposed the working principles of the helicopter But never built one. Not until the 20th century did a Russian engineer build the first controllable helicopter. Since then helicopters have filled the skies like dragon flies. But you asked why were helicopters invented? I don't think any one for sure knew why davinci was cgurious enough to think about it but its better we consider its advantages than reason for being invented. The helicopter has the ability to fly at altitudes practically impossible for any aeroplane,secondly it can land just about any were: field,water,mountains,farms and anywere else an aeroplane cant get to at low speeds. It can suspend itself in air for as long as its engine can bare and within its weight limit. Some can even hover backwards. See it has greater advantages than the aeroplane over short distances and difficult terrains. Find out the rest
