The Blackburn Pellet was a single-engined, single-seater biplane flying boat designed as a contender for the 1923 Schneider Trophy competition.

A flying boat (the Supermarine Sea Lion III) had won the contest the year before, and in addition, Blackburn had the elegant hull of the unfinished N.1B fleet escort bomber in store since 1918.

This used a system of circular formers separated by stringers and covered with a double layer of 0.125 in (3.2 mm) mahogany strips, the second at right angles to the first.

The engine, a 450 hp (340 kW) Napier Lion was cooled with radiators fitted flush in the lower surface of the upper wing.

It set off in the morning to the trials, but on the takeoff run, baulked by a small boat,[2] the aircraft began porpoising and was wrecked[3] the pilot, R.W.Kenworthy escaping unhurt.
