PZL M-20 Mewa
The PZL-Mielec M-20 Mewa (Polish: ''Gull'') is a licence-built version of the Piper PA-34 Seneca II manufactured in Poland by WSK PZL Mielec in a limited series from the 1980s. Development A licence to build the PA-34-200T was purchased in 1978, when WSK-Mielec started to co-operate with Western manufacturers. The Polish aircraft were to be fitted with PZL-Franklin F6A-350 engines. The first Mewa, partly assembled from US-delivered parts, flew on 25 July 1979. However, the Polish communist authorities were reluctant to produce civil aircraft of this class as there was no civil aircraft free market in Poland at that time. As a result, the second prototype, built in Poland, was not flown until 1982 and the third M-20 02, being the basis for serial production, on10 October 10, 1985. In 1988, an air ambulance version M-20 03 was developed, with Teledyne Continental TSIO/LTSIO-360-KB engines. After 1990 production of the Mewa commenced for the civilian market.

WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

PZL Aircraft
PZL (''Państwowe Zakłady Lotnicze'' - State Aviation Works) was the main Polish aerospace manufacturer of the interwar period, and a brand of their aircraft. Based in Warsaw between 1928 and 1939, PZL introduced a variety of well-regarded aircraft, most notably the PZL P.11 fighter, the PZL.23 Karaś light bomber, and the PZL.37 Łoś medium bomber. In the post-war era, aerospace factories in Poland were initially run under the name WSK (Transport Equipment Manufacturing Plant), but returned to adopt PZL acronym in late 1950s. This was used as a common aircraft brand and later as a part of names of several Polish state-owned aerospace manufacturers referring to PZL traditions, and belonging to the ''Zjednoczenie Przemysłu Lotniczego i Silnikowego PZL'' - PZL Aircraft and Engine Industry Union. Among the better-known products during this period is the PZL TS-11 Iskra jet trainer and PZL-104 Wilga STOL utility aircraft. After the fall of communism in Poland in 1989, these ma ...

1970s Polish Civil Utility Aircraft
Year 197 ( CXCVII) was a common year starting on Saturday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Magius and Rufinus (or, less frequently, year 950 ''Ab urbe condita''). The denomination 197 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

PZL M-26 Iskierka
PZL M26 Iskierka ( en, Sparklet, Sparkle, Little Spark) or M26 Airwolf is a Polish trainer and aerobatic aircraft, designed at WSK PZL-Mielec (later PZL Mielec). Design and development The M26 Iskierka was conceived as an economical plane for civilian pilot training and primary selection of military pilots. It offers training in both VFR and IFR flying as well as aerobatics. Its construction is partly based upon the twin-engine PZL M-20 Mewa utility plane ( Piper PA-34 Seneca II, built under licence in WSK-Mielec). It shares the vertical stabilizer, rudder and main landing gear with the Mewa, while the wings and tail part of fuselage are unified to some degree. The plane is constructed according to FAR-23 rules. The main designer was Krzysztof Piwek. The first prototype M26-00, powered by a PZL-Franklin 6A-350C1 air-cooled flat-six engine rated at , flew first on July 15, 1986. The second prototype was the more powerful M26-01 variant, powered by a Lycoming AEIO-540-L1B5D e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PZL-F 6A-350C1R
The Franklin O-335 (company designations variations on 6A and 6V) was an American air-cooled aircraft engine of the 1940s. The engine was of six-cylinder, horizontally-opposed layout and displaced . The power output of later variants was . Design and development These engines were commonly vertically mounted and used to power many early helicopters in the United States. They were closely related to the 2A4 and 4A4 2- and 4-cylinder engines. In various subtypes, the 6A4 remained in continuous production from 1945 to the time Franklin's United States operations ceased in 1975, with versions continuing in Polish production into the 1990s. In 1947 this engine was modified into a water-cooled version by the Tucker Car Corporation for use in the 1948 Tucker Sedan The Tucker 48, commonly referred to as the Tucker Torpedo, was an automobile conceived by Preston Tucker while in Ypsilanti, Michigan and briefly produced in Chicago, Illinois in 1948.

NACA Airfoil
The NACA airfoils are airfoil shapes for aircraft wings developed by the National Advisory Committee for Aeronautics (NACA). The shape of the NACA airfoils is described using a series of digits following the word "NACA". The parameters in the numerical code can be entered into equations to precisely generate the cross-section of the airfoil and calculate its properties. Origins NACA initially developed the numbered airfoil system which was further refined by the United States Air Force at Langley Research Center. According to the NASA website: Four-digit series The NACA four-digit wing sections define the profile by: # First digit describing maximum camber as percentage of the chord. # Second digit describing the distance of maximum camber from the airfoil leading edge in tenths of the chord. # Last two digits describing maximum thickness of the airfoil as percent of the chord. For example, the NACA 2412 airfoil has a maximum camber of 2% located 40% (0.4 chords) from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lotnicze Pogotowie Ratunkowe
State Medical Rescue ( pl, Państwowe Ratownictwo Medyczne, PRM) in Poland is a system of free public emergency healthcare established by ''Ustawa o Państwowym Ratownictwie Medycznym'' (''State Medical Rescue Act''), including ambulance service and Emergency Departments (EDs). While in Polish public hospitals and clinics NFZ common public insurance is required, PRM medical services in ambulances and EDs are completely free for everyone. Since 2018 emergency ambulances that operates in PRM, that is Polish 112 and 999 emergency numbers, are operated by public entities only (mostly voivodeships and cities dependent organisations). Standards Operating system At the moment, the operating system of Polish EMS is similar of the Austrian- Franco-German-Spanish delivery model, and is physician-led and an Integrated EMS of Public Health (IEMS). Physicians (usually anaesthetists) respond to most emergency calls, and a great deal of definitive care and even simple physician consultat ...
