Collections Research volunteer Daniel researched this object from the Powerhouse Collection, Object No. 94/27/1, a composite photograph of Lawrence Hargrave flying a kite at Stanwell Park.
This remarkable sequence of five photographs captures a pivotal moment in the history of early aviation experimentation. Taken around 1897, the images show Hargrave testing one of his innovative “soaring kites” on the beach, part of a series of experiments designed to better understand how lift could be generated and controlled in horizontal wind.

Hargrave had already made headlines just a few years earlier. On 12 November 1894, also at Stanwell Park, he demonstrated that stable flight was possible by lifting himself 16 feet into the air using four cellular box kites. This daring experiment helped establish a crucial principle: that controlled, sustained lift could be achieved with the right design.

By the time these photographs were taken, Hargrave had shifted toward refining his ideas with a safer and more methodical approach. His experimental setup, visible in the images, was deceptively simple. Two 24-foot poles were anchored in the sand and connected by a cord, from which a kite was suspended at the midpoint. A flag mounted on one of the poles indicated wind direction, while the kite’s upward pull relative to the wind allowed Hargrave to observe lift performance without risking damage to his designs, or himself.

Through repeated trials using this apparatus, Hargrave explored the impact of wing curvature on lift efficiency. He became particularly interested in shapes inspired by bird wings, developing designs with curved surfaces and thicker leading edges. While his theoretical understanding of aerodynamics wasn’t entirely accurate, his practical insights proved invaluable.

Hargrave was confident in the implications of his work, writing: “A very few trials will convince the most sceptical that if we are not soaring in moderate breezes before the end of the century it will not be from ignorance of the way to do it.” His optimism reflected a broader shift in thinking – flight was no longer a fantasy, but an engineering problem within reach.

Importantly, Hargrave chose not to patent his designs. Instead, he published his findings in a series of papers for the Royal Society of New South Wales, making his work freely available to others. This openness likely influenced later pioneers, including the Wright brothers, whose development of efficient aerofoils and eventual success in powered flight in 1903 built on ideas that experimenters like Hargrave helped bring into focus.
Today, Hargrave is recognised not only as an inventor and engineer, but also as a key figure in the global story of aviation.
Many thanks to Daniel for uncovering this great story about the object.
