The Bristol Babe was a British-built light single-seat biplane, intended for the private flyer and produced immediately after the First World War. Only two flew.
The Bristol Babe was the creation of Frank Barnwell, a flying enthusiast as well as Bristol's chief designer. It was aimed at the private owner flyer and was a small single-engined single-seat biplane with unswept staggered single-bay wings of unequal span. Full-span ailerons were fitted on the top wing only. The fuselage was plywood-skinned, with fabric covering it for protection. The cockpit was below the upper wing trailing edge with rounded decking aft to the tail. The fin and rudder were generous and rounded, the undercarriage a conventional single-axle plus tailskid arrangement.
Finding a suitable small engine proved difficult. The original intention was to use the 60 hp (50 kW) ABC Gadfly radial, but in April 1919 ABC pulled out of aero-engine manufacture. A possible alternative was the 40 hp (30 kW) flat-twin Siddeley Ounce currently being developed, so a third Babe was begun as a testbed. In the meantime, Barnwell resurrected a 1911 Viale 35 hp five-cylinder radial engine of 45 hp (34 kW) that had been installed in an Avro Type F and which had been put into storage following a crash. This engine ran satisfactorily for up to half an hour, after which it tended to overheat. This was installed in the second Babe which made its first flight on 28 November 1919. The pilot, Cyril Uwins reported that it was an easy aircraft for an experienced pilot but rather unstable for a novice. Though it was useful for testing, the old Viale was not reliable enough for sale, so following discussions at the Paris Aero Show in November 1919, two seven-cylinder 60 hp (50 kW) Le Rhône Type 7B2 rotary engines were ordered for the first two Babes. The third Babe appeared at this show with an incomplete Ounce engine.
