who is the known as the father of aviation
George Cayley In 1799 he set forth the concept of the modern aeroplane as a fixed-wing flying machine with separate systems for lift, propulsion, and control.[2] [3] He was a pioneer of aeronautical engineering and is sometimes referred to as "the father of aviation."[1] He discovered and identified the four forces which act on a heavier-than-air flying vehicle: weight, lift, drag and thrust.[4] Modern aeroplane design is based on those discoveries and on the importance of cambered wings, also identified by Cayley.[5] He constructed the first flying model aeroplane and also diagrammed the elements of vertical flight.[6] He designed the first glider reliably reported to carry a human aloft. He correctly predicted that sustained flight would not occur until a lightweight engine was developed to provide adequate thrust and lift.[7] The Wright brothers acknowledged his importance to the development of aviation.[7]
