Period

This model anti-G suit used c. 1939- early 1940 [possibly for testing purposes only]

Canada

Dr. W.R. Franks, Professor in Medical Research, University of Toronto was a leader in aviation research work conducted in Canada during the late 1930s-1940s on problems associated with acceleration. Among his accomplishments in the field, Franks developed an anti-G suit (the " F.F.S."] which applied pressure to the calves, thighs and abdomen to prevent pooling of the blood in the veins of these areas, and supported the increased pressure developed in the arterial bed of the same regions. This prevented blackouts and unconsciousness, and delayed the onset of fatigue- critical problems for pilots subjected to centrifugal force during aerial manoeuvrers. [Ref. 6] This heavy fabric bag previously identified as Franks' suit component, and tentatively identified as a camera bag. [Ref. 3] This [and other versions of the F.F.S.] required testing in a controlled and reproduceable environment. For this purpose, a "human centrifuge", the R.C.A.F. accelerator was designed and constructed. [see 1987.0229 and 1976.0529]. [Ref. 5]

Function

Presumably used to protect contents by limiting exposure to environmental changes.

Technical

The Mark III F.F.S. was the first anti-G suit to be used in actual air operations anywhere in the world. It demonstrated the value and practicality of anti-G suits, which lead to further development of the technology and later versions of the Franks suit. The first prototype suit was constructed of thin cotton and made to fit Franks himself . It was sewn together in Franks' office at the University of Toronto, and had thin rubber bladders vulcanized throughout, allowing the wearer's full body to be protected by a thin film of water. Franks wore the suit during testing in a Finch Fleet biplane. He realized that not all areas of the body required equal protection from G-forces, and modified his original prototype accordingly. This piece may be one of the elements of the refined prototype suit. [Ref. 6, p.114]
