A scale drawing for a wheel design, perhaps for his Hawk glider. Pilcher was a pioneer in the use of wheels for gliders.
A sketch of a 'reconstructed' Hawk glider and a 4hp steam engine with two cylinders dating to around 1898.
A scale drawing for a wheel and axle, perhaps for his Hawk glider. Pilcher was a pioneer in the use of wheels for gliders.
A sketch of a Hawk glider, perhaps his 'reconstructed' version dating to around 1898.
A half inch to one foot scale drawing of the Pilcher Triplane.
A scale drawing, of a scraper-shaped wooden part, perhaps a tail section for his Hawk glider dating to the mid-1890s.
A one inch to one foot scale drawing of a Pilcher glider, probably the Bat. It has been suggested that this drawing was the original concept for Pilcher's Bat glider and was probably the drawing used to in the manufacture and construction by direct scaling and a few calculations, with development of…
A one and a half inch to one foot scale drawing of the crossbar for his 300 foot glider. This is similar to a crossbar on a drawing of the Hawk in the RAeS collection, though it also looks similar to a crossbar used for the Gull in 1896.
