Description
The PZL-Mielec M-18 Dromader is a single-engine Polish agricultural and firefighting aircraft designed by WSK-Mielec (later PZL-Mielec) in the mid-1970s. Due to the political situation of operating in an Eastern Bloc country, the manufacturer sought assistance from U.S. aircraft manufacturer Rockwell International to facilitate global sales through U.S. Federal Aviation Administration certification. This cooperation resulted in the M-18 sharing outer wing panels and fuselage sections with the Rockwell Thrush Commander, while integrating the ASz-62 engine and structural modifications. The first prototype flew on August 27, 1976, and received Polish certification in September 1978. A total of 759 aircraft were built by 2012. While production has been halted, refurbishments with new WSK "PZL-Kalisz" engines continue, and plans exist to renew production at WZL-2 in Bydgoszcz.
Design
The M-18 features outer wing panels with a NACA 4416 root airfoil and a NACA 4412 tip airfoil. It is powered by a 731 kW (980 hp) PZL Kalisz ASz-621R 9-cylinder air-cooled radial piston engine driving a four-bladed, 3.3-meter diameter PZL Warszawa AW-2-30 constant-speed aluminum alloy propeller. For agricultural and firefighting roles, the aircraft is equipped with a fiberglass hopper located forward of the cockpit, which has a capacity of 2,500 liters of liquid or 2,200 kg of dry chemicals.
Operational History
The Dromader has been exported to 24 countries. Over 200 units operate in the United States, and 15 were sold to China in 2008. Military and state operators include the Hellenic Air Force, the Montenegrin Air Force, Serbia's Agricultural Aviation, and the Croatian Air Force as a former operator. Civil operators utilize the aircraft for cropspraying and firefighting, including the Turkish Aeronautical Association and the former Yugoslav airline Jugoslovenski Aerotransport.
