The PZL SW-4 is a light-weight, single-engine helicopter of Polish origination. It is manufactured under the storied PZL-Swidnik brand label and can be used to accomplish a variety of over-battlefield missions as well fulfill various civilian market / industry rrequirements. A first-flight in prototype form was recorded on October 29th, 1996 and series introduction occurred in 2002. The series remains in active service, flying solely with the modern Polish Air Force. Production has been ongoing since 1996.

This Light Utility Helicopter (LUH) is in the same class as the American MD Helicopters MD500 series, the Bell 206, and the Eurocopter Colibri - all three helicopters detailed elsewhere on this site.

The SW-4 has a relatively basic, conventional design showcasing clean lines and a streamlined appearance. The cockpit seats two side-by-side with a compact, three-person passenger cabin integrated directly aft. The engine sits behind and over the cabin and used to drive a three-bladed composite main rotor and twin-bladed tail rotor unit offset to port side. The drive shaft servicing the latter is housed within the tail stem structure which seats a vertical dorsal and ventral fin as well as horizontal planes used in flight control. The helicopter sits atop a simple twin-skid undercarriage, keeping maintenance requirements low. The cockpit sports redundant flight controls for both pilot positions and features a shared instrument panel. A center console divides the two crew spaces and vision out-of-the-cockpit is exceptional due to the liberal use of window panels across the forward section of the fuselage.

Dimensions of the SW-4 include a running length of 34.7 feet, a main rotor diameter of 29.5 feet, and a height of 10 feet - overall a relatively compact footprint for a helicopter of this class. Empty weight is 2,315lb with a Maximum Take-Off Weight (MTOW) reaching 4,000lb.

Power is derived from a single Rolls-Royce 250-C20R/2 series turboshaft engine develop 451 horsepower, driving the helicopter to speeds of 160 miles-per-hour. It can reach an altitude in excess of 17,000 feet and a range out to 490 miles. Rate-of-climb is 2,030 feet-per-minute.

Forty total helicopters in the series have been built to date (2022) with some 24 taken into service by the Polish Armed Forces where they serve as helicopter trainers. The civilian market form, appearing in 2016, is designated as "AW009". The SW-4 "Solo" is an optionally-piloted version of the helicopter and a joint development between PZL and helicopter powerhouse AgustaWestland. Work on this form was begun in 2011.©MilitaryFactory.com
