Curved Wings

Hargrave realized that aspiration, the ability to rise into the air, was connected to wing curvature. So he used the winds at Stanwell Park to test the aspiration qualities of curved wing surfaces. He developed his ‘soaring machines’ during the last 2 years at Stanwell Park, 1897-99.

The machine was tied to the rope slung between two poles 24 ft high and 48 ft apart, guyed to the surrounding beach. It had the freedom to fly about the rope without dashing itself on the ground.

Hargrave's work, like that of many another pioneers was not sufficiently appreciated during his lifetime. Most of his models ended up in a German museum in Munich, due to protracted negotiations over safe housing of them in Sydney. Unfortunately many were destroyed by Allied bombing during WWII, the rest repatriated back to Australia later.

Our aim is to draw attention to the pioneering contribution that
Lawrence Hargrave made to the development of human flight,
as well as championing his interest in the natural heritage
and cultural development of Stanwell Park.

We are available for exhibitions, displays of Lawrence Hargrave models and educational activities.
