The Short L.17 Scylla was a British four-engined 39-seat biplane airliner designed and built by Short Brothers at the request of Imperial Airways to supplement the Handley Page H.P.42 fleet already in service after Handley Page quoted an excessive price for two additional H.P.42s.
Imperial Airways used the Scylla for scheduled flights from London to Paris and other European cities. Two aircraft were built, Scylla (G-ACJJ) and Syrinx (G-ACJK). Both served with the airline until its merger into BOAC in 1939 and both were taken out of service the following year.
The Scylla was a land-based development of the Short Kent (S.17) flying boat, essentially using the Kent's aerostructure above a redesigned fuselage. It was an all-metal biplane (wingspan of 113 ft, 34,44 m) powered originally by four Bristol Jupiter XFBM radial engines mounted on vertical struts between the upper and lower planes. The square-section braced-framed fuselage was below the lower wing; the tail had a single vertical stabilizer and a horizontal stabilizer at about one quarter height. The Scylla was originally fitted with a Flettner-type servo tab trim control to ease the forces on the rudder controls. An experimental servo tab on the rudder was tested on G-ACJJ Scylla for a time. Experience gained with the latter possibly contributed to a later patent application submitted jointly by Shorts and Dudley Lloyd Parkes on 7 August 1936.
The main undercarriage had one fixed wheel on each side, mounted on three diagonally-braced struts, one to the upper and two to the lower edge of the fuselage; there was a single tailwheel. Ailerons were fitted to both upper and lower wings.
