What was the first British helicopter to fly and by whom?

Answer 1

Best I could Find -




Hafner R II.
Built in 1930 at Vienna, Austria, this was a second variant of the R I, powered by a single Salmson 9 Adr radial piston engine. A single seat experimental helicopter, the initial tests in Vienna proved little more successful than those with the R I and in 1932 the team with the R II moved to Heston Airport in Middlesex. The R II was under-powered to do more than just hover inches of the ground, and eventually went into storage. The R II was rediscovered in a crate in 1961 and refurbished by Westland apprentices and returned to temporary storage. The aircraft joined the museum in May 1979, and a survey showed the
need for extensive restoration and this was undertaken jointly by a group of Westland
volunteers and the Glider Support Unit based at RAF Locking. Following this work it was evident that this historic helicopter needed to be properly protected from the elements and it was mutually agreed to place it with the Museum of Army Flying at Middle Wallop, which could provide suitable undercover protection. In 1996 Raol Hafner's widow officially donated the R II to the museum, and in April 2000 it returned to the Helicopter museum to go on permanent display.

Answer 2

The best answer I can find is -

1800 : Sir George Cayley ( UK )
Already famous for his work on the basic principles of flight, which dates from the 1790s, had constructed several successful vertical-flight models with rotors made of sheets of tin and driven by wound-up clock springs.
In a scientific paper, published in 1843, Cayley mention a vertical flight machine called "Aerial Carriage." However, Cayley's device remained an idea because the only power plants available at the time were steam engines, and these were much too heavy to allow for successful powered flight.

1842 : W. H. Phillips ( UK )
Build a 10 kg steam-powered model.
