Flying machine model ‘Experiment H,J,K’

Made by Hargrave, Lawrence in Rushcutters Bay, New South Wales, 1887.

The Museum of Applied Arts and Sciences holds the largest collection of material internationally of the aviation pioneer, Lawrence Hargrave. While no single individual can be attributed to the invention of the aeroplane, Hargrave belonged to an elite body of scientists and researchers (along with Octave Chanute, Otto Lilienthal and Percy Sinclair Pilcher) whose experiments and inventions paved the way for the first powered, controlled flight achieved by the Wright Brothers on December 17, 1903.

Production

This flapping wing machine model, designated as either 'Experiment H,J,K' or the '11th flying machine', was produced by Lawrence Hargrave in Rushcutters Bay, New South Wales, Australia in 1887.

The model is constructed from light wood and paper in the membrane of the plane and it is powered by twenty-four rubber bands. There is no device for steering. The paper used in the plane's membrane replaces a previous experiment using muslin (a type of cotton fabric), which was found to buckle under pressure.

The specifications of this flapping wing model were modified twice during the course of Hargrave's three experiments. Initially, it was built with an area of 1986 sq in, but it was later reduced to 1974 sq in.
