Shortly after the 1931 competition, an R engine using a special fuel blend powered the winning Supermarine S.6B aircraft to a new airspeed record of over 400 miles per hour (640 km/h). Continuing through the 1930s, both new and used R engines were used to achieve various land and water speed records by such racing personalities as Sir Henry Segrave, Sir Malcolm Campbell, and his son Donald; the last record was set in 1939.A 1951 R-powered water speed record attempt by Donald Campbell was unsuccessful.
在1931年比赛后不久,一台"R"发动机在使用一种特别的混合燃料做动力的情况下,使得一架获胜的休泼马林公司的S.6B飞机飞出了超过400英里1小时(640 km/h)的新记录,在随后的30年代里,崭新的和使用过的"R"发动机在亨利·西格雷夫,坎贝尔·马尔科姆爵士及他的儿子唐纳德·马尔科姆这些竞赛名人的手中创造了一系列的陆地及水面速度记录,最好记录于1939年创造,1951年唐纳德·马尔科姆尝试刷新R发动机载动的水上速度记录但没有成功。

In this part, the densities of sodium benzoate, sodium nitrobenzoate, sodium chlorobenzoate and sodium methylbenzoate in DMFwater mixed solvents have been measured at 298.15K with an Anton Paar Model 55 densimeter. From these densities, apparent molar volumes and partial molar volumes have been calculated, transfer volumes from water to DMF-water mixtures and substituent contributions to the transfer volumes have also been obtained. Solvent and substituent effects are discussed in detail. The Scaled Partical Theory has been applied to the ternary solutions to evaluate the partial molar volumes of cavity formation and the volumes change associated with solute-solvent interaction.
