PZL SW-4 Puszczyk is a general-purpose multi-purpose helicopter developed in 1996 by the Polish aircraft manufacturer PZL-Swidnik.
The project of the PZL SW-4 Puszczyk helicopter began to be created by Polish aircraft manufacturers back in the 60s of the last century, however, for several reasons, the project was closed for almost 20 years, and only in 1981, experts again began to finalize the design of the future aircraft. Due to the lack of sufficient funding, the project was postponed until the beginning of the 90s of the last century, and only then the aircraft developers received an appropriate proposal to resume work on the design and manufacture of helicopters of the PZL SW-4 Puszczyk model.
Initially, the helicopter was supposed to be a purely civilian aircraft, however, due to quite a lot of competition, both among European and American manufacturers, the project began to be exclusively military, although it was not considered a combat aircraft.
For the first time, the PZL SW-4 Puszczyk helicopter model took off in October 1996, however, for several reasons this aircraft was presented to the public only in 2002.
In the military sphere of its operation, this aircraft is used exclusively as a transport and passenger aircraft, used, as a rule, for transporting high-ranking officers, for conducting observation flights, and also as a means for conducting air patrols. The PZL SW-4 Puszczyk helicopter does not have its weapons, and therefore its operational capabilities are very limited.
In the cockpit of the PZL SW-4 Puszczyk helicopter can accommodate up to 5 people, including one pilot and four passengers (military personnel). As such, the PZL SW-4 Puszczyk model helicopter is not intended for the transport of goods, however, it can transport small loads on its board, although in very small volumes.
According to official 2010 figures, Polish aircraft manufacturers produced 40 aircraft of the PZL SW-4 Puszczyk model, while, according to 2014, production continues, although in very limited quantities.
The power plant of the PZL SW-4 Puszczyk helicopter includes a 457 hp Rolls-Royce Model 250-C20R / 2 gas turbine engine. The aircraft can accelerate to a speed of 260 km \ h (maximum indicator), with the ability to fly over distances of up to 790 kilometers.
Helicopters of the PZL SW-4 Puszczyk model are operated in countries such as Poland, Brazil, Italy, China, Ukraine, South Korea, and Indonesia, and their use is both in the military sphere and civilian.
