The Partenavia P.53 Aeroscooter was a 1950s Italian single-seat light aircraft fitted with a two-bladed rotor. It was designed by Mario de Bernardi and built by Partenavia.[1]

Design and development

The Aeroscooter was low-wing monoplane powered by a 22 hp (16 kW) Ambrosini P-25 piston engine in the nose.[1] It had a fixed nose-wheel landing gear.[1] Above the enclosed single-seat cockpit a pylon was to have been fitted with an autorotating, unpowered two-bladed rotor which was to reduce the stalling speed and the rate-of-descent if the engine failed.[1]

Only one Aeroscooter was built and it first flew on 2 April 1951 without the rotor fitted.[1] The Aeroscooter survives and is on display at the Museo Storico Dell Aeronautico Militare Italiana. A two seat derivative was produced by Mario de Baernardi as the de Bernardi M.d.B. 02 Aeroscooter.
