| Source measurement | — | The original design for the SW-4 called for it to be powered by a 300 kW (400 shp ) PZL Rzeszow GTD350 turboshaft engine, as featured upon the prototype mockup.[source]PZL SW-4 Puszczyk · Development / Origins; only the objects and conditions stated in this passage According to PZL-Swidnik, the early SW-4 could reach the rated top speed of about 240 km/h (130 kn ) and a max range with auxiliary fuel tank about 900 km (485 nmi ).[source]PZL SW-4 Puszczyk · Development / Origins; only the objects and conditions stated in this passage PZL-Świdnik's parent company, AgustaWestland chose to use the SW-4 as the basis for an optionally manned rotorcraft, the PZL-Świdnik SW-4 Solo. In 2011, development of an optionally-manned demonstrator began. The SW-4 Solo was first was shown at the MSPO 2012 in Poland as "SW-4 Solo" RUAS/OPH platform (Rotorcraft Unmanned Air System/Optionally Piloted Helicopter). In 2013, AgustaWestland was given a Royal Navy contract for the SW-4 Solo's development as part of the UK's RWUAS (Rotary Wing Unmanned Air System) Capability Concept Demonstrator (CCD) programme. Development of the SW-4 Solo is also being supported by the Italian Ministry of Defence 's Directorate for Air Armaments under the Italian National Military Research Plan. By September 2015, the SW-4 Solo had performed a total of 26 demonstration flights, which included simulated shipboard integration tests. In November 2015, AgustaWestland stated that the SW-4 Solo was "ready for sale".[source]PZL SW-4 Puszczyk · Development / Further development; only the objects and conditions stated in this passage The SW-4 is powered by a single 335 kW (450 shp ) (283 kW/380 shp max continuous rated) Rolls-Royce Model 250C20R/2 turboshaft engine, which drives the rotorcraft's three-blade main rotor and two-blade tail rotor. An alternative engine is provided in the form of the 460 kW (615 shp) Pratt & Whitney Canada PW200 /9 turboshaft engine. The main rotor is fully articulated and the rotor blades on both the main and tail rotors are composed of composite materials. The SW-4 uses hydraulic flight controls, the rotorcraft has been promoted as possessing excellent flight controls, and can be flown in both day and night visual flight rules conditions.[source]PZL SW-4 Puszczyk · Design; only the objects and conditions stated in this passage The SW-4 is capable of transporting up to five people, including a pilot, in crashworthy seats; passengers are provided with a high level of external visibility and comfort, an optional vibration absorption system is also offered. The main cabin can be rapidly reconfigured between passenger and cargo-carrying configurations and is accessed via two sliding doors on either side of the cabin, a dedicated baggage compartment is also present beneath the main cabin. PZL- Świdnik stated that multi-role operations had been a high priority during the SW-4's development; and that the rotorcraft is well-suited to passenger transport, primary and advanced training, patrol and surveillance missions.[source]PZL SW-4 Puszczyk · Design; only the objects and conditions stated in this passage Various optional equipment can be installed, such as removable co-pilot flight controls, wire strike protection system , a forward looking infrared (FLIR) sensor system, instrument flight rules (IFR) training fittings, radio altimeter, emergency medical system, moving map, external loudspeakers and/or search light, flotation gear, and an external cargo sling. Much of the external equipment is designed to be held on external extension arms; overall, the SW-4 can mount/carry a useful payload of up to nearly 600 kilograms. Both basic and advanced trainer variants of the SW-4 have been developed to conform with NATO standards and military pilot training regulations, it is promoted as possessing a high level of inherent flight stability and safety; the advanced model is compatible with night vision goggles (NVG) and is equipped with an emergency simulation unit.[source]PZL SW-4 Puszczyk · Design; only the objects and conditions stated in this passage Capacity: 4 passengers[source]PZL SW-4 Puszczyk · Specifications (SW-4); only the objects and conditions stated in this passage Length: 10.57 m (34 ft 8 in)[source]PZL SW-4 Puszczyk · Specifications (SW-4); only the objects and conditions stated in this passage Height: 3.05 m (10 ft 0 in)[source]PZL SW-4 Puszczyk · Specifications (SW-4); only the objects and conditions stated in this passage Empty weight: 1,050 kg (2,315 lb)[source]PZL SW-4 Puszczyk · Specifications (SW-4); only the objects and conditions stated in this passage Gross weight: 1,600 kg (3,527 lb)[source]PZL SW-4 Puszczyk · Specifications (SW-4); only the objects and conditions stated in this passage Max takeoff weight: 1,800 kg (3,968 lb)[source]PZL SW-4 Puszczyk · Specifications (SW-4); only the objects and conditions stated in this passage Powerplant: 1 × Rolls-Royce 250-C20R/2 turboshaft engine, 336 kW (451 hp)[source]PZL SW-4 Puszczyk · Specifications (SW-4); only the objects and conditions stated in this passage Main rotor diameter: 9 m (29 ft 6 in)[source]PZL SW-4 Puszczyk · Specifications (SW-4); only the objects and conditions stated in this passage Main rotor area: 64 m 2 (690 sq ft)[source]PZL SW-4 Puszczyk · Specifications (SW-4); only the objects and conditions stated in this passage Maximum speed: 260 km/h (160 mph, 140 kn)[source]PZL SW-4 Puszczyk · Specifications (SW-4); only the objects and conditions stated in this passage Range: 790 km (490 mi, 430 nmi)[source]PZL SW-4 Puszczyk · Specifications (SW-4); only the objects and conditions stated in this passage Service ceiling: 5,200 m (17,100 ft)[source]PZL SW-4 Puszczyk · Specifications (SW-4); only the objects and conditions stated in this passage Rate of climb: 10.3 m/s (2,030 ft/min)[source]PZL SW-4 Puszczyk · Specifications (SW-4); only the objects and conditions stated in this passage |
