PZL 104 Wilga-80

Multipurpose plane

In 1958, at the Aviation Structures Center in Warsaw, the design of a new multi-purpose aircraft for glider towing, parachutist training and for sanitary purposes and agriculture was started.

In 1961, a prototype of the aircraft, designated PZL 104 "Wilga1", was tested, but subsequent factory trials forced the designers to completely redesign the aircraft. The new, fully metal structure, designated" Wilga-2 ", met all the requirements and in 1963 mass production began several versions at the same time:
"Wilga-2P" - passenger and liaison service
"Wilga-2A" - aero club (towing gliders, transporting parachute jumpers)
"Wilga-2S" -sanitary
"Wilga-2R" ~ agricultural version.

The constantly changed and improved design aroused great interest in the country and abroad. In the seventies, further changes were introduced and a new engine - Continental 0-470-L with a power of 169 kW (230 (HP). The version was designated "Wilga-35". In the 1980s, "Wilga" was produced in two variants: "Wilga-35A" - according to the BCAR regulations and "Wilga-80" - according to the FAR regulations, including: with noise silencers and changed engine cooling In 1991, the "Wilga-80" flat Teledyne Continental Motors 10-550D engine with a capacity of 300 was used KM This new version, marked as Wilga 80-550, is characterized by even better performance.

The "Wilga-35A" and "Wilga-80" planes are used to take part in various types of aviation competitions in Poland and abroad. These planes fly in 19 countries, including Canada, Egypt and the USA.

The PZL 104 "Wilga" airplane is a multi-purpose, four-seat, cantilever high-wing, all-metal structure with a fixed landing gear. It belongs to the category of short take-off and landing aircraft.

Technical data:
Span -11.13 m; length - 8.03 m; height - 2.98 m; bearing area -15.5 sq m; curb weight - 870 kg; flight weight -1300 kg, speed - max -196 km / h; speed of climb - 5 m / s; ceiling - 4000 m; range - 600 km; flight duration - 3.5 h; run-up -121 m; reach -104 m.

PZL-104 WILGA 2

Polish multipurpose aircraft

PZL-104 WILGA in the original version created by Ing. Orlowski, was flown in 1961, but the results achieved were not satisfactory. Therefore, a group of technicians led by Ing. Žurakowski redesigned the entire aircraft from the ground up, both aerodynamically and structurally. The fuselage, tail surfaces, landing gear and its mountings were redesigned. The entrance to the cabin was also originally completed - instead of four doors, only two, but quite large. A new, more advanced version, named "WILGA-2", was already flown in August 1963. Series production of a neat machine of purposeful shapes was then started in several variants:
- 2A aero club, for glider lifts and parachutist jumps
- 2P transporter, for the pilot and three passengers
- 2R agricultural, for spraying and powdering with a tank for 250-300 kg of chemicals
- 2S ambulance, for a patient on a stretcher and a doctor.
Another use of the aircraft is for geological exploration and transport of loads up to 500 kg. For export, the production flexibly adapted to the wishes of the customers by installing the American Continental 0-470 engine of 225 к with a metal adjustable propeller.

TECHNICAL DESCRIPTION
The PZL-104 "WILGA-2" is a single-engine all-metal self-supporting high-wing aircraft with a fixed undercarriage and spur.
A wing of slenderness 8 has one main spar and an auxiliary spar for ailerons and flaps only. There are slotted slots along the entire leading edge of the wing. The cover of the ailerons and flaps is enforced to increase rigidity. When the flaps are deflected, the ailerons are also deflected accordingly. A Pitot nozzle is woven into the end of the right half of the wing, and there is a landing reflector in the end arc of the left half of the wing. The profile used is NACA 2415, the adjustment angle is +1°.

The hull is structurally quite divided - the front part consists of two half-shells, the rear part is a conical shell, reinforced longitudinally by moldings and reinforcement. The cabin is richly glazed - including the upper side. The doors on both sides open upwards. Steering is lever in front of the left front seat. The dashboard is equipped with common flight and engine instruments, an artificial horizon and an on-board radio station.

The tail surfaces are also all metal. The steering wheel is aerodynamically balanced. The VOP is semi-self-supporting with a brace, the height is also aerodynamically balanced. The cover of the rudders is enforced as for the ailerons. The profile of the tail surfaces is symmetrical with a thickness of 12%. The battery is located in the keel, under the shaped cover.

Landing gear. The unusual chassis has 500 x 150 wheels suspended on swingarms, shock absorbers are separate off the axis of the wheel and chassis. The spur damper is mounted at the very end of the hull and its wheel is 255 x X 110.
Engine group. A flat six cylinder WN-6RB2 engine with a starting power of 185 к drives a two-blade adjustable wooden propeller type 2 D 2.65. The fuel tanks in the leading part of the wing have a total capacity of 175 1. An oil cooler is built under the engine.

The coloring is quite varied. The sketched aircraft (SP-PEA), exhibited at the Poznań Fair in 1964, had this finish: over the duralumin sheet in the original color transparent paint, only the upper part of the fuselage and SOP white. A red band all over the torso, two bands also on the SOP. The end of the wing and VOP are also red. Red color all over with white border. In the red band on the fuselage silver inscription PZL-104 - WILGA-2P and on the engine cover WN-6RB. The registration marks and the PZL emblem are black, as are the propellers and part of the fuselage in front of the cabin.

Technical data and performances: span 11.1, length 8.0, height 2.7 m; wing area 15.5 m²; weights - empty 670, take-off 1150 kg; surface load 74 kg/m². Speeds - maximum horizontal 200, travel 170, work 110-130, minimum 85 km/h. Climb rate at the ground 4.5 m/s, practical reach 4000 m, range 700 km.
