Bristol Jupiter Fighter

The Bristol Type 76 Jupiter Fighter and the Type 89 Trainer were derivatives of the First World War F.2 Fighter, powered by Bristol Jupiter radial engines. To demonstrate the new engine in an inexpensive aircraft, Bristol converted three war surplus F.2 airframes into the Type 76, the first flying in June 1923. The engine installation worked, but the same fuel capacity and the Jupiter's higher consumption left inadequate range, and slipstream stopped the observer using his Lewis gun, so no more were built. The success of the installation led to the Type 89 Trainer, of which 23 were produced, used as an advanced trainer between 1924 and 1933.
