Junkers Ju 87 below 3g and had lasted no longer than three seconds. In a crouched position, pilots could withstand 7.5g and were able to remain functional for a short duration. In this position, Junkers concluded that ⅔ of pilots could withstand 8g and perhaps 9g for three to five seconds without vision defects which, under war conditions, was acceptable. During tests with the Ju 87 A-2, new technologies were tried out to reduce the effects of g. The pressurised cabin was of great importance during this research. Testing revealed that at high altitude, even 2g could cause death in an unpressurised cabin
Bristol Aeroplane Company Bristol Record Office include the papers of Lionel Harris, an engineer at the Bristol Aeroplane Company in the 1940s (Ref. 42794) (online catalogue) The Bristol Engine Company was originally a separate entity, Cosmos Engineering, formed from the pre-First World War automobile company Brazil-Straker. In 1917, Cosmos was asked to investigate air-cooled radial engines and, under Roy Fedden, produced what became the Cosmos Mercury, a 14-cylinder two-row (helical) radial, which they launched in 1918. This engine saw little use but the simpler nine-cylinder version known as the Bristol Jupiter was clearly a winning design. With the post-war rapid contraction of military
