The PZL M-24 Dromader Mini (Dromader is Polish for "Dromedary"), orginally named the Lama (Polish for "Llama"), is a single engine agricultural aircraft, developed in the 1980s by the WSK-Mielec (later PZL-Mielec) from the PZL-Mielec M-18 Dromader. It did not progress beyond the prototyping stage.
Development[edit]
The plane was developed as a smaller variant of the successful M-18, intended for smaller areas of land, up to about 50 hectares (120 acres). The design was intended to retain as much commonality with the M-18 as possible; ultimately around 70% was achieved. Common areas included the cabin, rear fuselage, empennage, outer wing panels, and mainwheels. The desire to maximise this commonality resulted in an overall weight greater than what would otherwise have been necessary.
The prototypes were tested from 1982 to 1986, when the design was certified. However, PZL did not have capacity to manufacture the design alongside the company's existing programs and no further examples were built.
A turboprop version, the M-21T, powered by a Walter M601A, was designed but never constructed.
Design[edit]
The M-21 is a conventional, low-wing cantilever monoplane with fixed, tailwheel undercarriage. Construction is of metal throughout. It is equipped with a single seat in an enclosed cabin. Power is supplied by a single PZL-3SR radial engine mounted tractor-fashion in the nose.
